3.84kWh 3.6kW Off Grid Energy Storage System with MPPT Solar Charging

This compact off grid energy storage system combines a 3.84kWh LiFePO4 battery, 3.6kW inverter and MPPT solar charging. It is designed for selected essential loads at small homes, cabins, remote offices and service points where daily energy use can be carefully managed.

Plan Around Essential Energy

The 3.84kWh battery is best used for a controlled group of loads rather than every appliance at the site. Lighting, routers, laptops and selected refrigeration can be prioritized according to their wattage and operating hours.

The inverter can supply up to 3.6kW continuously, but high power shortens the available operating period. Daily watt-hour consumption should therefore be calculated separately from peak load power.

Solar-First Operation with AC Recovery

The MPPT input supports a 60–500Vdc operating range, 500Vdc maximum open-circuit voltage and 18A input current. The proposed solar string must remain within these electrical limits.

When solar production is insufficient, a compatible utility or generator source can recharge the battery. The source must provide stable voltage and frequency within the inverter’s AC input range.

Protect the Available Battery Reserve

Two output channels allow essential equipment to be separated from flexible loads. The combined output remains 3.6kW, and motor startup demand should be checked before connection.

The system does not support grid export or parallel operation. Its role is to store energy and supply local loads from one standalone system.

3.84kWh Off-Grid System FAQ

Can the system operate without utility power?

Yes, when the solar array, stored energy and load profile are properly matched.

How long will the battery operate the loads?

Operating time depends on total wattage, usage hours, conversion losses and the retained battery reserve.

Can a generator recharge the system?

A compatible generator may be used when its voltage, frequency and continuous output meet the AC input requirements.

Can electricity be exported to the grid?

No. Grid-connected export is not supported.

What data is needed for off-grid sizing?

Provide appliance wattage, operating hours, motor startup power, sunlight conditions and solar-panel specifications.
