ESR Series Hybrid Inverter-EnSmart

ESR Series Hybrid Inverter can control the flow of energy intelligently and protect against power outage. The PV energy can be provided to the load, fed into the public grid and charge the battery during the daytime. And the energy stored in the battery can be discharged to power the load during night time. The public grid can also charge the battery via the hybrid inverter.
