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.
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.
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.
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.
| Nominal Energy Reserve | 11.52kWh / 25.6V / 450Ah |
| Continuous Output | 3.6kW / 220 or 230Vac / Pure Sine Wave |
| Instantaneous Power | 5400VA |
| PV Charging Window | 60–500Vdc MPPT / 500Vdc Maximum Voc / 18A |
| AC Source Input | 230Vac / 170–280Vac or 90–280Vac / Auto 50–60Hz |
| Maximum Charging Current | 100A PV, AC or Combined |
| Load Output Arrangement | Two AC Channels / 3.6kW Total |
| Monitoring and Data | LCD / RS232 / RS485 / CAN |
| Installation Conditions | IP22 / Indoor Protected Area / No Grid Export |
Suitability depends on peak power, daily energy use, required reserve and available charging energy.
No. The maximum continuous inverter output remains 3.6kW.
They may operate when their combined and startup demand remain within the inverter limits.
Yes, when the generator output is compatible with the inverter’s AC input requirements.
Provide the complete day-and-night load schedule, startup demand, local sunlight and generator information.
Send your 24-hour energy profile and solar conditions. We will review whether 11.52kWh provides enough off-grid reserve.
