Microtek introduces a new and unique device ‘Solar Management Unit “. SMU (solar management unit) is a special and unique Indian device that converts your simple Inverter into a Solar Inverter. -The same SMU works on both 12V & 24V inverters.
The charging process is designed for long battery life and improved system performance. Comprehensive self-examination and extensive electronic protection can prevent damage to the wrong cable or system errors.
When the sunlight is full the solar charge controller charges the solar battery with the first value of solar energy, when the battery is fully charged, it runs the load from the sun and automatically starts to move the load to the power back in the evening. The solar management unit gives priority to the solar panel.
In this SMU, you get a built-in PWM Solar Charge controller, which maintains the efficiency of solar panels and solar battery life for a long time.
