Dual AC Power Center: 12kW 30kWh All In One Energy Storage System for Homes

An Integrated Power Center for Split Phase Energy Projects

This 12kW 30kWh all in one energy storage system brings the inverter, battery, dual MPPT solar charger, monitoring interface and communication functions together in one coordinated cabinet.

The system provides 12kW of pure sine wave output and 30.72kWh of rated battery energy, with approximately 27.6kWh available at 90% depth of discharge. Its 120/240Vac split phase architecture is designed for projects using L1, L2 and neutral distribution.

For solar installers and distributors, the integrated layout reduces the number of separate components that must be matched, positioned and connected. It is suitable for larger homes, remote properties and generator-supported solar storage projects.

How the All In One Design Simplifies Installation

Dual AC Output for Smarter Load Control

The dual AC output is intended to help installers separate higher-priority circuits from flexible loads. This provides a clearer way to manage stored energy when the property is operating from the battery.

The final output assignment depends on the selected operating mode, local electrical code and distribution-board design. Pumps, air conditioners and other motor-driven appliances must be checked for both running and startup power.

Solar, Battery and Generator Operating Strategy

During periods of solar generation, photovoltaic power can support compatible loads and charge the battery according to the selected priority settings. The two MPPT inputs support up to 6kW of solar input per channel.

When solar production falls, the integrated battery can supply selected circuits. Utility power or a compatible generator may also support loads or battery charging according to system configuration.

The maximum photovoltaic charging current is 220A, while the maximum utility charging current is 160A. When solar and utility charging are used together, the combined charging setting must remain within the specified 0–200A range.

Engineering and Installation Data

Integrated Energy Storage Project Checklist

• Confirm that the site uses compatible 120/240Vac split phase service.
• List continuous and startup power for the proposed AC loads.
• Decide which circuits belong on the primary and secondary outputs.
• Keep each photovoltaic input within 6kW and 22A.
• Keep PV operating voltage within 90–485Vdc and open-circuit voltage below 500Vdc.
• Confirm generator voltage, frequency and available power capacity.
• Provide stable floor support, cable access and maintenance clearance.
• Install the IP21 cabinet in a dry indoor or protected technical location.

All In One Energy Storage System FAQ

What equipment is consolidated inside this energy storage system?

The platform combines split phase inverter output, battery storage, dual MPPT solar charging, system display, WiFi monitoring and multiple communication interfaces in one cabinet.

How can dual AC outputs improve system operation?

They allow the installer to separate priority circuits from flexible loads. The final control behavior depends on the output settings and electrical distribution design.

Can solar and utility power charge the battery at the same time?

Combined charging is supported, but the total charging current must be configured within the specified 0–200A combined limit.

What is the benefit of having two 6kW MPPT inputs?

The two channels allow separate solar strings to be designed within their individual limits. This can simplify projects with two roof areas or different panel orientations.

What generator information should be checked before commissioning?

The installer should confirm generator voltage, frequency, continuous output capacity, wiring arrangement and the charging current required by the project.

Which communication options are available for installers?

The system includes LCD display, WiFi monitoring, RS485, RS232, USB and dry-contact interfaces for available monitoring, commissioning and external-control requirements.
