Off-grid solar systems require batteries to store energy, are not connected to the local grid and are self-sufficient. On-grid solar systems are connected to the electricity grid and therefore do not need batteries. This is the main difference between off-grid and on-grid solar power system.

What Is the Difference Between PWM and MPPT Charge Controllers?
Solar charge controllers control the energy coming from the solar panels, adjust the current and voltage, then send it to the batteries. A charge controller is needed in every solar energy system. Charge controllers are divided into two as PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking).
