Product Description

1.1 Configuration
AC CHARGER,DC CHARGER,AC(OUT) INVERTER and FRONT PANEL

1.2 Working Principle
The system adopts AC charge and solar charge with MPPT. AC will complement the electricity when the solar energy is poor. The system is also with the function of bypass. AC will offer electricity first, but it will convert to inverter output if AC is off or it's over/under voltage, with 1-route 48V output and the max load is 5A.
