What are MC Connectors and Cables?

What are MC Connectors and Cables?

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.

Inverter Basics and Selecting the Right Model

Inverter Basics and Selecting the Right Model

We carry many types, sizes, brands, and models of inverters. Various options are also available. Choosing which one is best from such a long list can be a chore. There is no "best" inverter for all purposes - what might be great for an ambulance would not be suited for an RV.

What is Maximum Power Point Tracking (MPPT)

What is Maximum Power Point Tracking (MPPT)

An MPPT, or maximum power point tracker is an electronic DC to DC converter that optimizes the match between the solar array (PV panels), and the battery bank or utility grid. To put it simply, they convert a higher voltage DC output from solar panels (and a few wind generators) down to the lower voltage needed to charge batteries.

Solar Charge Controller Basics

Solar Charge Controller Basics

A charge controller or charge regulator is basically a voltage and/or current regulator to keep batteries from overcharging. It regulates the voltage and current coming from the solar panels going to the battery. Most "12 volt" panels put out about 16 to 20 volts, so if there is no regulation the batteries will be damaged from overcharging.

What is Lithium Battery Technology?

What is Lithium Battery Technology?

Lithium batteries stand apart from other battery chemistries due to their high energy density and low cost per cycle. However, "lithium battery" is an ambiguous term. There are about six common chemistries of lithium batteries, all with their own unique advantages and disadvantages.

Deep Cycle Battery Types Comparisons

Deep Cycle Battery Types Comparisons

There is more to comparing batteries than just cost or amp-hour ratings. For example, based only on cost, the Concorde AGM's do not look so good. On the other hand, you probably would not want to store a flooded battery in your computer room. There is no one best battery for all applications.

Solar Power Technical Tips and Nice to Know Information

Solar Power Technical Tips and Nice to Know Information

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.
