Frequently Asked Questions

Why does my battery-based RE system need both a charge controller and a battery charger The charge controllers featured here regulate energy input from RE sources like PV arrays, wind turbines, or microhydro generators. You'll generally need a separate controller for each RE charging source. Think of your battery as a tank with multiple pipes filling it. Each pipe needs its own valve to regulate the source when the tank gets full. Most residential-scale, battery-based inverters have a battery...

Features You Want

In addition to protecting batteries from overcharging, most whole-house charge controllers have many other features. Here are several to consider. Maximum power point tracking. If you're installing a whole-house battery-based PV system, buy an MPPT controller. In most applications, MPPT controllers will generate about 15 percent more energy annually than systems with non-MPPT controllers. And they generate more energy when you likely need it most during the winter when the PVs are cold, the...

Charge Controller Ratings

When selecting a charge controller, consider both its voltage and current ratings. Most of the charge controllers featured here can be programmed or configured to operate at different nominal battery voltages, but double check that the controller you select is compatible with your system's nominal battery voltage. All PV charge controllers have an absolute maximum open-circuit voltage (Voc) rating. Exceeding this rating can damage the controller, and overvoltage-related failures are not covered...
