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.
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.
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.
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.
| Stored Energy | 7.68kWh / 25.6V / 300Ah LiFePO4 |
| Local Load Output | 3.6kW Rated / 5400VA Instantaneous |
| AC Output Quality | 220/230Vac ±5% / 50 or 60Hz / Pure Sine Wave |
| PV Input Window | 60–500Vdc MPPT / 500Vdc Maximum Voc / 18A |
| AC Charging Source | 230Vac / Automatic 50–60Hz Detection |
| Battery Current Rating | 100A Maximum Charge / 150A Maximum Discharge |
| Battery Stack | Base Battery plus One Expansion Section |
| System Interfaces | RS232 / RS485 / CAN / LCD |
| Operating Location | IP22 / Dry Indoor or Protected Technical Area |
Suitability depends on total overnight energy consumption and the reserve retained by the system.
Available solar power can support local loads and battery charging according to system conditions and settings.
Yes, when the generator output meets the inverter’s voltage, frequency and power requirements.
No. Grid-connected export is not supported.
Daily energy use, effective sunlight, panel voltage and required battery recovery time determine the array design.
Send your daytime and overnight load schedule. We will assess whether 7.68kWh provides sufficient usable reserve.
