The simple difference between the use of inverters and controllers:
First of all, the function of the inverter is simple and clear, which is to convert the 12V/24V/48V/72V DC power (battery, storage battery
, DC power supply) into the 110V/ 220V/380V AC power commonly used in households.
The controller is used when the photovoltaic module is used to charge the battery. It can maintain a stable charging process, avoid overcharging the battery, and prevent the battery from flowing back and causing backflow damage to the photovoltaic module. Therefore, the full name of the controller Also called solar charge and discharge controller, divided into MPPT solar controller and PWM solar controller.
When choosing, pay attention to the specific use requirements and the configuration of photovoltaic modules, and choose the appropriate inverter or controller.
