15.36kWh 3.6kW Off Grid Solar Battery System With Extended Energy Reserve

15.36kWh 3.6kW Off Grid Solar Battery System with Extended Energy Reserve

This off grid solar battery system combines a 15.36kWh LiFePO4 battery bank with a 3.6kW inverter and MPPT charging. It provides the largest energy reserve in the series for remote sites with moderate peak power and longer daily operating requirements.

Use the Battery as a Managed Reserve

The larger battery may support longer evening, overnight or low-solar operation, but every load should still be classified by importance. Essential equipment should receive priority over flexible or high-consumption devices.

The inverter supplies 3.6kW continuously. A large remaining battery reserve does not allow the system to exceed this output limit.

Provide Enough Energy for Daily Recovery

The solar input operates from 60–500Vdc with a 500Vdc maximum open-circuit voltage and an 18A current limit. The solar array should provide enough daily energy to support loads and restore the used battery capacity.

A compatible generator or utility source can provide recovery charging during poor weather. Available charging time becomes especially important when a large part of the battery is used each day.

Control Peak Loads and Output Circuits

The inverter provides 5400VA instantaneous power, but pumps, compressors and other motor loads should still be checked for startup demand.

Two AC channels can separate essential loads from flexible equipment. Total output remains 3.6kW, and the system does not support parallel operation or grid export.

15.36kWh Off-Grid System FAQ

Can this system provide several days of energy?

That depends on daily consumption, solar production, battery reserve and generator availability.

Is it suitable for a remote clinic or farm office?

It may be suitable when the peak load remains within 3.6kW and daily energy use fits the charging plan.

Can the system operate a large water pump?

The pump’s running and startup power must be checked against the inverter limits.

Can a generator restore the battery during poor weather?

Yes, when the generator provides compatible voltage, frequency and sufficient continuous power.

What should be provided before quotation?

Provide daily energy consumption, peak and startup power, solar conditions, generator data and required reserve time.
