What do I need to know about batteries for solar applications?
Understanding how different batteries work, the maintenance involved, and understanding basic formulas all help you make the best decision for your specific needs. Our team of application engineers is here to make it easy, but we know some people really want to have a good understanding of their options before they decide to make this kind of investment.
Solar Powered EV Charging Systems are a combination of solar modules (panels), an inverter, an EV charging station, and optionally battery storage and a connection to The Grid.
These systems allow the user to collect solar energy and convert it into power that is used to charge an electric vehicle. Depending on the design and components, these systems may also be set up with battery storage or be used to draw from or “sell back” power to the Grid.
Are you looking for a reliable and affordable solution for your off-grid solar power needs?
We want to tell you about Victron Energy, a trusted partner for off-grid solar power solutions. Since 1975, they have been providing high-quality power conversion equipment for multiple applications and challenges.
Our product offerings include inverters, chargers, batteries, and charge controllers...
Solar charge controllers are used to regulate the charging of a battery bank. Solar panels produce voltage and current that are variable in nature — meaning they’re a function of the amount and uniformity of solar irradiance (watts per meter squared from sunlight) that a solar panel receives. However, this is not what a battery can use to charge. Battery charging must be done in a highly regulated and specific manner. The amount of voltage and current a battery receives must not vary outside of a small range (too low and no charging will occur; too high and over charging, and possible damage to the battery bank, will occur). The device that regulates the output of a solar panel in order to use the variable power it produces to charge a battery is known as a charge controller. There are two kinds of charge controllers—PWM (pulse-width modulation) and MPPT (maximum power point tracking) charge controllers. Both have a distinct charge regulation method and a similar battery charging algorithm.
Electrical wiring is the conductor that connects components in your system. In most cases, solar system wiring should be copper with properly rated insulation for the location the wire will be occupying.
As the cost of living increases, so does the struggle to find affrdable housing. At the same time, many occupations have transitioned to a digital or remote format, or employers have realized the possibility of offing that flexibility to their workers. These factors have increased the usage of RVs, campers, buses, boats, vans and other vehicles as second or in some cases even primary homes. Rather than being saddled with a mortgage or rent with no equity, many people are packing up their lives and hitting the road or water. Of course, that life isn’t for everyone—some prefer to keep their RVs or boats as a parttime or seasonal activity rather than a residence. But whatever the application, electric power comes into play.
What are off-grid/DC-powered refrigerators and freezers?
Solar refrigerators and freezers are highly effcient units with exceptionally low energy consumption. These appliances require a small photovoltaic (PV) system. DC refrigerators are powered directly from a battery bank which can be charged via solar and a genset/gas generator. The brushless DC motor compressor operates on 12 or 24V DC.
Water pumps are used to transfer water from one point to another by converting mechanical energy into pressure (head). Electrical energy typically drives the mechanical pump, whether from the grid, solar direct, batteries or an inverter. There are various things to keep in mind when selecting a pump and designing a system. Here we’ll discuss the multiple types of pumps, the application requirements which will define suitable pumps, and the overall concepts for powering the pump in a sustainable manner.
The term “off grid” means just that—power and energy are generated from sources other than an electrical utility or power company. Off-grid solar systems incorporate components required for a standalone electrical power system. This includes energy generation from photovoltaic solar panels, energy storage usually in battery form and power generation utilizing an inverter/charger. Off-grid systems can also incorporate secondary energy generation from a fuel-powered generator and sometimes hydro-electric and wind power generation and more rarely fuel cell electric generators.
A grid-tied solar system is connected to the utility grid. This is the most common system type for those who already have commercial electricity at their home. Grid-tied systems offer a simple and cost-effctive way to offset electric bills with solar energy. At their core, simple grid-tied systems consist of two main components: solar panels and an inverter. The solar panels collect light from the sun, and a chemical reaction inside the panel converts the light energy into DC electricity. This DC power is then sent to the inverter, which converts it to usable AC power before sending that power to the loads in your home. If the loads in the home are satisfied, and the solar panel array is producing excess power, a typical grid-tied system will send the extra power back to the grid. Most customers will get some kind of credit or reduction in their electric bill for selling excess solar production to their utility company. Any energy used by the home (such as at night, when it’s cloudy or if there are extra power needs) is purchased from the utility company like normal.
Selecting batteries for your solar power system can be overwhelming. With all the different types, sizes and varying price points, it's easy to get confused. We’re here to help you make the best decision for your needs and budget. If you want to take a deep dive into battery chemistry, please check out Battery chemistry, care, and terminology.
System configuration is imperative if it’s going to do exactly what you want it to do—whether that’s properly charging your batteries, getting your hybrid system prepped for load shaving or setting your battery monitor to accurate setpoints. Most inverter manufacturers have external devices capable of setting up whole-system management, as long as all major components—like the charge controller, battery monitor and inverter—are from that same manufacturer. However, a few other manufacturers over standalone items that are capable of setting up remote system monitoring all on their own—some even without a Wi-Fi signal present.
Backup power systems are a way to keep things operating during power outages. You may already be familiar with a UPS (uninterruptable power supply), which is a specific type of backup power system that keeps your computer running long enough during a blackout to save your work before shutting down. A backup power system can be attached to essential appliances like a refrigerator so your food doesn’t spoil. Or, they can be large enough to run a whole house or even a business.
Change is on the horizon for California Grid-Tie Solar customers. The California Public Utilities Commission (CPUC) has approved new Net Metering rules for grid-tie solar energy systems – NEM 3.0. Effective on April 13, 2023, the new Net Metering rules will stretch out the payback period for grid-tie solar power systems in the Golden State by reducing how much customers are paid for their solar generated power.
Many people are excited by the idea of producing electricity from the sun to power their home. However, they may be discouraged when they think of all the paperwork they will need to wade through to get permission from the utility company to install a system. You don't always need to ask your Utility Company for permission to install a solar power system on your home. One could take advantage of a grid-zero configuration.
Grid-tie solar systems are appearing in more and more neighborhoods as homeowners seek to reduce their rising electricity bills, charge electric vehicles, or just “green up” their energy footprint. However, many people are surprised to learn that the grid-tie solar panels on their roofs don’t supply power to the home when there is a utility blackout. This is due to the ani-islanding safety requirements of a grid tie solar power system.

Our latest customer story shifts to Colorado. Tom, who spent 4 years in the US Air Force and worked in the airline industry for 32 years, moved to Colorado in 2005 along with his wife to build their own log home.
Understanding battery types and chemistries can be confusing for those new to solar energy. It’s important to understand the basics of how they are different so you can choose the right battery type for your solar power application.
One of the most common questions asked by customers is how to integrate a battery backup solution with an existing grid-tie system. As designed and required by law, grid-tie systems shutdown during a grid power outage. The main reason is to make sure solar panels are not back-feeding power into the grid while line workers are attempting to make repairs.
When investing in a solar system, it is normal to inquire about the longevity. There are several components to a solar power system, so it is important to consider everything when evaluating the life expectancy of the overall system.
Getting away from the complexity of the traditional American Dream and trying a different approach at life is the desire of many. Trends indicate that Americans are transitioning into smaller homes or taking their life on the road. A couple from Austin TX is living their new dream traveling the USA with no regrets. James and Kelly sold their home in Austin to live on the road in their 39’ fifth wheel. Both being able to work remotely gives them the perfect opportunity to travel the country with their three border collies. Their passion is exploring nature and trail running in new locations along their travels.
A common misconception about grid-tie solar systems is that during a power outage or grid failure, the solar system will continue to provide power to loads. Due to the nature of grid-tie solar systems and how they are designed, all power output to the grid must cease during an outage unless other backups are designed into the solar system, which basically changes the nature of the system entirely.
This week’s solar system spotlight features Jessa and Dan. They have been together for 19 years but decided that settling down wasn’t the lifestyle they wanted. Owning their own business gave their family the opportunity to travel full-time. They purchased a 1972 Boles Aero Travel Trailer which they rebuilt from the frame up and hit the road.

Our solar project this week features customer David G. of Northern Arizona. David and his family purchased property in the high desert of Northern Arizona to be closer to extended family. Their intention wasn’t necessarily to go off-grid with their power needs, however, the location where they purchased their property dictated solar to be their only power option. That’s when David researched solar power and ultimately contacted our team at Northern Arizona Wind & Sun.
When looking at what is an ideal full system configuration for an RV, typically one would want to consider the expectations of a system and limitations of the RV, and then build the system around these expectations and limitations. In most cases you want to start from the roof and work your way down.
Solar for Roof
Roof space is usually the biggest limitation when considering solar power for an RV. Being that solar panels are one of the least expensive aspects of a complete system, maximizing production value for a given space is the most advantageous plan. In most cases putting as many panels on the roof as will fit is the best idea. Measure or use pieces of cardboard, targeting a sixty-cell panel format (~67”x40”). These are technically the best panels and the cheapest, due to the volume of sales these panels enjoy. Other panel sizes are available. Mixing sizes and shapes is complicated so plan wisely. We’ve never had a customer complain about having too much power (because this isn’t possible) but having too little power can result in too little energy production which may not meet your expectations. This can be frustrating and could lead to premature battery failure or other system wide issues.
Next you need to plan for an inverter if you need to run AC appliances and devices. The inverter converts power from the batteries to your basic household outlet AC power, 120VAC or 120/240VAC. You need to decide whether you want a fully integrated inverter system or a simple stand-alone inverter. In most cases, this decision will be dictated by what you want to power from the inverter. If you simply want to plug in a laptop or charge a phone from time to time, then a stand-alone inverter should work fine. Most of these smaller inverters will have an outlet on the front allowing low power devices to be connected. Anything more demanding than this requires a fully integrated inverter/charger. These inverter/chargers have a built-in transfer switch and the ability to charge the batteries at a much higher current than a typical converter. These are advanced inverter/chargers with powerful features and thus are usually the best solution for medium to large installations. The inverter/charger is typically placed between the shore power input and the main electric panel, the output from this inverter would go to the main electric panel. This essentially will power up all or most of the electrical circuits within the RV, depending on the configuration of the electrical panel. When AC input power is present from either shore power or generator, the inverter/charger will qualify the input (making sure it’s acceptable) and transfer that power through. It will pull from the AC input dynamically depending on certain limitations to charge the batteries. When shore power or the generator are not present the inverter uses energy from the batteries to power the AC loads. There are many more advanced features available from this type of inverter/charger, but in general if you power to all the outlets and appliances like the micro wave or the air conditioner then an inverter/charger is the way to go. Special care needs to be taken if you wish the inverter/charger to power air conditioners. Air conditioners consume large amounts of energy and need careful planning.
The final step in a design is sizing the battery bank. An RV is a terribly abusive environment for batteries. It’s common to have significant deficit cycling (infrequent full charges), over discharge is very likely, and temperature can vary significantly. There are two types of batteries that work for an RV system; lead acid and lithium-ion. Lead-acid batteries include flooded batteries (AGM), or Gel. However, gel lead acid batteries are not designed for the demands present in a typical RV system.
Can be placed inside the living space
Battery bank can be added to over time
Low chance of damage if left uncharged
Higher level of efficiency
Cost- Lithium batteries are more expensive, however, over the life of the system Lithium is cheaper.
Larger and heavier than Lithium
It’s not recommended to add to a lead acid battery bank after it’s installed
Life is significantly reduced if they are left uncharged for any length of time
Cheapest battery option
Must be placed in a vented enclosure designed to handle the gas fumes they create
Extremely heavy - it’s important to make sure that the location can handle the weight
Poorly suited to handle the abuse present in an RV system
Not recommended to add to their battery bank.
It’s important to have an accurate battery monitor installed in the system, one that uses a shunt. This will allow for accurate tracking of the battery state of charge. Regardless of the type of battery bank, this accessory can really help prevent excessive discharge and confirm regular recharging.
You can do all the research you want but some of the best recommendations you’ll get are going to come from experts in the industry. Northern Arizona Wind & Sun has several engineers on site happy to consult and design a system to suit your application, no matter how unique or complicated. Feel free to give us a call to discuss your project today.
A lot of people assume they need a transfer switch for an off-grid system when they are using a generator to charge the batteries or power loads. If you are using an inverter/charger there is an internal transfer switch to select between the inverter’s output and an incoming AC source. Most inverter/chargers will remain in “Invert” mode unless they see an acceptable AC source coming through (Shore / Grid Power or Generator Power). Once the inverter/charger accepts the AC voltage, it transfers over to supply power to loads and dump excess power into the batteries. Once this AC source is disconnected, the inverter will transfer back to “invert” mode and use battery power to run the loads. Some inverter/chargers will accept two AC sources and transfer between either of those and the inverter’s output. So if this is how your system would be set up, then there is no need for an external transfer switch.
You may need an external transfer switch if you have an inverter/charger with only one AC input and you want to switch between two AC sources like a generator and shore/grid power. This is the case in most mobile/RV applications. Another scenario is when you have a generator that can deliver more power than the inverter/charger can pass through and you want to power some heavy loads. The inverter charger is limited by the rating of the internal transfer switch. For example: Let’s say we have a Schneider 3.8kW inverter/charger with an internal 30A transfer switch with a split phase 120/240VAC output. The max load we can run by passing the generator power through is 7.2kW (30A x 240VAC = 7200 W). If we had a load that exceeded this 7.2 kW, and we had a generator that was able to satisfy this load, we would want the inverter/charger to be bypassed, allowing the generator to power the load directly. In this event we could use an external transfer switch to select between the inverter’s output and the generator’s output. If the inverter/charger is properly sized, this scenario does not occur often.

If you’re looking to go solar for your home or business, you should know that there are incentives that help offset the investment. These are both at the national and state level and include tax incentives and favorable policies that make it easier for residents to adapt to solar energy. We’ve put together a few examples for each state, with the total number of incentives listed in parenthesis. For a comprehensive list visit http://www.dsireusa.org/.
For systems put "into service" between 2009 and 2019, the federal tax credit is 30%. That means that for solar electric systems put into service between Jan 1, 2009, and Dec 31, 2019, you will be able to get back 30% of the total cost of the system, with no cap for residential systems.

Grid-Interactive? What does THAT mean?? Grid-interactive is kind of a hybrid system, battery-based but they also feed any excess power back to the grid and draw from the power grid when the solar panels are not producing enough.
This table lists the American Wire Gauge (AWG) sizes for copper conductors. In addition to wire size, the table provides values for load (current) carrying capacity, resistance, and maximum frequency. The resistance and skin depth noted are for copper conductors only.
Includes 12, 24, and 120-volt charts and a metric to AWG size conversion table. This is a five percent table which means at these amperage ratings at the listed distances, 5% of the power would be lost to resistance.
MC connectors are specially designed for low contact resistance and good stable connections under a wide range of conditions. MC means "multi-contact." The term "multi-contact" comes from the fact that the connectors have a bunch of little spring loaded gold plated fingers that ensure good contact.
Numerous charts and lists have been published with long lists of appliances and how much power they draw. You are then supposed to add up all the watts, then find out how many hours of sun you get, etc etc.
An "RV system" (small boat and cabin systems are practically identical) can mean different things to different people. It might be just a small 5-watt panel that keeps the battery charged up between a few trips a year or over the winter.
