11.52kWh 3.6kW Off Grid Energy Storage System With MPPT AC Charging

11.52kWh 3.6kW Off Grid Energy Storage System with MPPT and AC Charging

This off grid energy storage system provides 11.52kWh of LiFePO4 battery capacity with a 3.6kW pure sine wave inverter. It is designed for remote sites that need a longer night-time reserve while maintaining controlled peak power.

Build a Complete Daily Energy Plan

The battery can support lighting, communications, refrigeration, computers and other selected equipment according to their daily watt-hour use. The 3.6kW output limit applies regardless of the remaining battery energy.

Flexible loads should be operated during periods of stronger solar production. Stored energy can then be preserved for essential evening and overnight equipment.

Recover Energy from Solar or AC Power

The MPPT input operates from 60–500Vdc, with a 500Vdc maximum photovoltaic open-circuit voltage and an 18A input-current limit.

A compatible generator or utility source can support charging when sunlight is insufficient. The daily charging plan should replace the energy used before the next operating cycle.

Control Peak Power and Priority Circuits

The inverter provides 3.6kW continuous power and 5400VA instantaneous output. Pumps, refrigeration compressors and other motor loads should be reviewed before inclusion.

Two AC outputs can separate priority loads from equipment that may be restricted. Parallel operation and grid export are not supported.

11.52kWh Off-Grid System FAQ

Can the system support a remote clinic or office?

Suitability depends on peak power, daily energy use, required reserve and available charging energy.

Will the larger battery increase maximum load power?

No. The maximum continuous inverter output remains 3.6kW.

Can high-power loads run during strong sunlight?

They may operate when their combined and startup demand remain within the inverter limits.

Can generator charging support poor weather periods?

Yes, when the generator output is compatible with the inverter’s AC input requirements.

What is needed for an accurate system review?

Provide the complete day-and-night load schedule, startup demand, local sunlight and generator information.
