What is the best MPPT solar charge controller?

The best MPPT solar charge controllers up to 40A including Victron, Epever, Morningstar and Renogy Rover. Unlike battery inverters, most MPPT solar charge controllers can be used with various battery voltages from 12V to 48V.

What types of solar charge controllers are available?

We feature a wide range of both MPPT and PWM solar charge controllers. See the BlueSolar and SmartSolar Charge Controller MPPT - Overview. In our MPPT model names, for example MPPT 75/50, the first number is the maximum PV open circuit voltage. The second number, 50, is the maximum charge current.

Do inverter/Chargers need a charge controller?

On the other hand, inverter/chargers are not equipped to directly charge batteries from the DC current provided by a PV array. A charge controller is needed to appropriately match the PV voltage to the battery and regulate charging. In some PV + storage applications you may only need a charge controller.

Can I oversize my MPPT solar charge controller?

Oversizing by 150% (Nominal rating x 1.5) is possible on many professional MPPT solar charge controllers and will not damage the unit. However, many cheaper MPPT charge controllers are not designed to operate at full power for a prolonged amount of time, as this can damage the controller.

Which charge controller is best for PV & storage?

In most cases the MPPT style charge controller, such as the PT-100, is the better choice, capturing PV energy far more efficiently and allowing for more flexible configurations of solar panels and batteries. Almost all PV + storage applications require both an inverter/charger and a charge controller.

What is a PWM solar charge controller?

PWM solar charge controllers are a great low-cost option for small 12V systems when one or two solar panels are used, such as simple applications like solar lighting, camping and basic things like USB/phone chargers.
