Product Overview
6.5kW Single Phase Off-Grid Solar Inverter for Remote Solar Power Systems
The 6.5kW single phase off-grid solar inverter is designed for standalone photovoltaic power systems in remote areas without utility grid access.
Adopting a 48V DC battery system, this off-grid inverter integrates a built-in MPPT solar charge controller and supports both solar PV charging and AC generator charging.
Compatible with gel batteries, lead-acid batteries and lithium batteries, the inverter supports CAN/485 BMS communication for intelligent battery management.
With 6.5kW continuous AC output power, dual AC output circuits and flexible charging methods, this 48V standalone solar inverter is suitable for remote houses, small farms, cabins, campsites and other independent solar energy applications.
The inverter is designed as an off-grid only power conversion device and cannot be connected to utility grids.
