About this product
The SMU could charge battery automatically from photovoltaic (PV) systems. The charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and extensive electronic protection can prevent damage against incorrect wiring or system faults. The system can work as a domestic inverter and a solar inverter automatically or manually through a switch except in night condition. In night condition the system will work as normal domestic inverter. The charging process has been optimized for long battery life and improved system performance. The comprehensive self-diagnostics and extensive electronic protection can prevent damage against incorrect wiring or system faults.
If the sunlight is full then solar charge controller charge the solar battery with the first priority of solar energy, when the battery is fully charged, it runs the load from the solar and automatically starts running the load on the power back in the evening. Solar management unit gives first priority to solar panel’s power.
