If you are planning to install off grid solar, you must have come across these terms – MPPT solar charge controller and PWM solar charge controller. While solar charge controller may be in-built in a solar inverter/UPS, you would have to connect a charge controller externally if you are converting your normal inverter and battery into solar power system.
But why do we even need a solar charge controller? How does it work? Why can’t we directly connect solar panels to batteries?
We have made an interesting video using animation to explain everything. You just need just 3 minutes to learn the basics of solar charge controller. Watch now!
