There are an endless number of options when it comes to configuring your solar power system, which is excellent! But it can make decisions a bit more challenging. In this video, James, our sales manager and application engineer, talks about why he installed the Sol-Ark 12K Inverter on his home as part of his grid-tied battery backup installation as a grid-interactive system.

There is a growing trend of Americans wanting to down-size and sell their homes for a different lifestyle. Huge mortgages and the burden of living in substantial debt has led people to reassess their situations. With a large portion of jobs now being done remotely due to COVID-19, people can now work from anywhere if they have an internet connection. Despite the overall economic impacts of the virus, the RV market is hot and showing no signs of slowing down.

Lightning is the number one cause of catastrophic failures in solar electric systems and components. The first major reason is that many PV systems are poorly grounded and poorly protected. That is also the 2nd and 3rd major reason.

You often see inverters rated in volt-amps (VA or va) instead of watts. For a perfect resistance, such as a heating element, watts and VA are essentially the same. However, many appliances, especially motors, are not a "perfect" load. Thus, the watts actually used may be less than the VA - but the inverter sees the VA. The motor or appliance may be using only 100 watts, but the inverter sees an "apparent" power of 150 VA.

An off-grid solar electric system involves working with both alternating current (AC) and direct current (DC) voltages. These voltages can be lethal if all safety precautions are not followed.
