7.68kWh 3.6kW Off Grid Solar Energy Storage System With Dual AC Outputs

7.68kWh 3.6kW Off Grid Solar Energy Storage System with Dual AC Outputs

This off grid solar energy storage system combines a 7.68kWh LiFePO4 battery with a 3.6kW inverter and MPPT charging. It provides a balanced energy reserve for remote homes, shops, offices and other sites with controlled day-and-night loads.

Balance Daily Consumption and Night Reserve

The larger battery provides more potential operating time than the entry configuration. Essential equipment should still be calculated from wattage and daily operating hours.

Flexible equipment can be scheduled during stronger solar production, preserving stored energy for evening lighting, refrigeration, communications and other priority loads.

Solar Charging with Generator Support

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

A compatible generator or utility source can provide charging during poor solar conditions. Generator voltage, frequency and continuous capacity should meet the inverter input requirements.

Organize Local Loads through Two Outputs

Two AC channels can separate priority circuits from loads that may be switched off when battery energy is limited. The combined AC output remains 3.6kW.

Grid export and parallel-machine operation are not supported. The system is intended to supply local loads from one integrated unit.

7.68kWh Off-Grid System FAQ

Is this suitable for overnight essential loads?

Suitability depends on total overnight energy consumption and the reserve retained by the system.

Can loads operate while solar energy charges the battery?

Available solar power can support local loads and battery charging according to system conditions and settings.

Can a generator be used during cloudy weather?

Yes, when the generator output meets the inverter’s voltage, frequency and power requirements.

Can the system sell electricity to the grid?

No. Grid-connected export is not supported.

What determines the required solar array?

Daily energy use, effective sunlight, panel voltage and required battery recovery time determine the array design.
