46.08kWh 12kW All in One Solar Energy Storage System with Dual AC Output
This all in one solar energy storage system combines a 46.08kWh LiFePO4 battery bank, 12kW pure sine wave inverter, dual MPPT charging and two AC output channels. It offers a larger stored-energy reserve while retaining a compact vertical floor-standing footprint.
The configuration is suitable for larger homes, offices, retail buildings, farm facilities and small commercial projects where backup duration and daily energy shifting are more important than increasing inverter power beyond 12kW.
The 46.08kWh battery bank provides three times the nominal energy of the 15.36kWh entry configuration. The inverter output remains 12kW, allowing the larger battery to focus on operating time, energy shifting and backup reserve.
This separation between power and capacity is important. A project with high instantaneous demand may require more inverter power, while a project with long operating hours may benefit more from additional battery energy.
The battery arrangement uses one bottom battery and two middle expansion sections. Adding capacity vertically keeps the system organized and reduces the need for several separate battery cabinets.
Each middle section measures 750 × 450 × 260mm, while the bottom section measures 750 × 450 × 350mm. The inverter is positioned within the same 750 × 450mm footprint.
Two AC outputs help divide the project into essential and flexible circuits. Each channel is listed at up to 6kW when both outputs are used, with a combined maximum output of 12kW.
This arrangement can help preserve battery capacity for essential equipment by limiting lower-priority loads during outages, low-solar periods or scheduled energy-saving operation.
The inverter also supports parallel operation when more AC power is required. Parallel design should be confirmed together with the planned battery and load configuration.
Two MPPT channels accept separate solar strings, with 5000W and 18A listed for each input. This supports more flexible PV layout planning for different roof areas or array orientations.
AC charging from a compatible utility or generator source provides an additional recovery path when solar production is insufficient. The system includes RS232, RS485, CAN and LCD monitoring.
The IP21 system requires a dry indoor or protected technical area. It does not support grid export.

It suits projects that need a larger energy reserve while remaining within a 12kW AC power platform.
No. The documented dual PV input ratings remain the same across these configurations.
Yes. They can be planned as separate circuits while remaining within the channel and total output limits.
Parallel operation is supported, but the full project design should be confirmed before ordering.
Compare daily energy consumption, required reserve, available solar charging and the desired operating period.
Send the daily energy use, peak load and available solar capacity. We will help determine whether the 46.08kWh configuration offers the right reserve.
