7.68kWh 3.6kW All in One Energy Storage System with Modular Battery Stack
This all in one energy storage system combines a 7.68kWh LiFePO4 battery stack, 3.6kW pure sine wave inverter and MPPT solar charging. It provides twice the nominal battery energy of the entry configuration while retaining the same compact inverter platform.
The system is suitable for homes, offices and small shops that need additional evening energy or a longer backup reserve. The vertical stack keeps the battery and inverter together in one organized floor-standing layout.
The 7.68kWh battery increases potential operating time without changing the 3.6kW AC output. It can support a wider daily energy plan when loads remain within the inverter limit.
Two AC output channels can separate essential equipment from flexible loads. Both channels share the same 3.6kW total-output limit.
The configuration uses one battery base and one expansion battery section beneath the inverter. This increases capacity vertically while maintaining a consistent 450 × 420mm footprint.
The calculated complete net weight is approximately 80.3kg. The system should be installed on a stable floor in a dry indoor or protected location.
The MPPT range is 60–500Vdc, with a 500Vdc maximum photovoltaic open-circuit voltage and an 18A input-current limit. Solar-string compatibility should be confirmed before ordering.
A compatible AC source can provide charging when solar production is limited. Parallel operation and grid export are not supported.

| Power Capability | 3.6kW Rated / 5400VA Instantaneous |
| MPPT Input Range | 60–500Vdc / 500Vdc Maximum Voc / 18A |
| Battery Current Limits | 100A Continuous Charge / 150A Continuous Discharge |
| Monitoring Interfaces | RS232 / RS485 / CAN / LCD |
| Stack Components | Battery Base + One Middle Battery + Inverter |
| Installation Data | Approx. 80.3kg Net / IP22 / Indoor Protected Area |
It adds one battery section and doubles the nominal energy while retaining the same 3.6kW output.
No. The rated inverter output remains 3.6kW.
Yes, but the combined load across both channels must remain within 3.6kW.
The IP22 system should be installed in a dry indoor or protected area.
Compare daily energy use, peak power, required backup time and available solar charging.
Send the load profile and desired backup period. We will help determine whether 7.68kWh provides the right balance.
