Off-grid PV Inverter 4.8KW all-in-one Inverter/charger/controller

1. for solar/ wind/ hybrid power system.
2. combo of inverter, controller,charger
3. pure sine wave.
4. self-optimizing MPPT
Off grid PV Inverter SMB-1S series
Overview
Sunfine SMB Inverter is used in off grid solar power system. It convert DC current generated from the solar panels into AC current to loads, and if it absence of sunshine, the utility could be back power supply. If the power generated is enough for loads, the Inverter will charge excess electricity to Battery. While no PV input and utility, it will use power from battery automatically.
