Solar Charge Controller

A solar charge controller is to keep the battery from overcharging by regulating the voltage and current from the solar panel to the battery.

Yes! Solar charge controllers are a necessary element of any solar panel system for components' safety. It will prevent over-charging of your battery. The bigger your battery is, the more capacity you need for the solar controller.

MPPT is more recommended. Compared with the PWM solar controller, MPPT usually has 30% more efficiency in charging efficiency.

Not only is the charging efficiency improved, MPPT has the advantage of being more stable, so it is very suitable for areas with low irradiance or areas with less sunshine in winter.

Yes, you need an inverter and MPPT. An inverter for converting DC current to AC, and the MPPT for protecting the solar system.

Do Not connect the inverter to the solar charge controller directly. Charge controllers need the battery to control the input from solar panels.
