POWER SAVER BOX
This accessory when attached with pwm or mppt charge controller helps convert any inverter into solar inverter without any hardware modification. The power saver shuts off the mains supply to inverter during daytime when solar energy is available. This ensures that during daytime, the battery charging is done using solar energy only. In evening, the power saver automatically re-connects the mains supply to inverter so that batteries do not get discharged during night.
