12 KW / 48 KWh Stackable Solar ESS Energy Storage Systems For Large Home Energy Storage

Product Overview

A 48 kWh stackable home ESS using 3 × 16 kWh battery modules and a 12 kW split-phase inverter. The appliance-style design combines solar input and battery storage for compatible 120 / 240 V homes.

This product listing is the 48 kWh configuration of the 12 kW stackable series. It combines 3 nominal 16 kWh battery modules with the inverter section and base. The vertical architecture organizes the hardware in one coordinated stack for a planned residential solar and backup solution. The 12 kW split-phase inverter rating and the available battery-only output are separate design considerations.

Designed to Fit into the Home

An organized stack for easier installation planning

The inverter, battery modules and base use a coordinated format. This gives installers a defined equipment layout and helps simplify placement, cable routing and commissioning planning. The final installation remains subject to approved electrical connections and site conditions.

Home-appliance appearance

The smooth front panels, integrated LCD and freestanding form suit a residential utility setting. The enclosure keeps the solar-storage equipment visually compact while maintaining access for operation and service.

Built-in MPPT solar charging

The specified solar charging capability is 9 kW + 9 kW, with 120-450 V DC PV operation and a 500 V DC maximum open-circuit limit. A correctly designed PV array connects to the system through its specified input channels.

Split-phase power with a selectable energy reserve

The inverter specifies 120 / 240 V split-phase output, 12 kW split-phase power and 7.2 kW in single-phase mode. This 48 kWh configuration is selected for its stored energy; confirm the actual battery and inverter operating limits for the load plan.

The comparison image shows the three configurations in this series. This listing is for the 48 kWh configuration shown in the first product image. Additional battery modules increase stored energy; they do not automatically increase the inverter power rating. Future expansion requires confirmation of compatible modules, controls and installation limits.

Residential Application Scenarios

Large-home solar energy reserve

The 48 kWh configuration uses three nominal 16 kWh battery modules. It is intended for projects prioritizing stored energy for a larger home or estate, with the inverter remaining on the 12 kW split-phase platform.

Longer-duration selected-load planning

A three-module reserve can be evaluated for a longer backup target after a load survey. It is not a promise of whole-home autonomy: usable energy, power demand, reserve settings and recharge opportunities determine the operating plan.

Residential properties with variable solar production

A larger energy reserve can help accommodate a chosen solar charging and household consumption schedule. The PV array must still remain within the inverter input specifications, and seasonal generation should be checked during system sizing.

Direct Solar Input and Home Power Flow

PV strings connect to the MPPT solar charging inputs. The integrated inverter and battery system then supports the selected AC load arrangement, with grid input available through the specified AC-input interface. The two PV input channels are rated 9 kW + 9 kW and 27 A + 27 A. Array open-circuit voltage, operating voltage and current must satisfy the specified limits across local conditions.

This is a functional power-flow concept, not an installation drawing. The grid connection is shown as AC input. Grid export approval, generator compatibility and parallel inverter operation are not established by the supplied datasheet. Battery quantity changes the nominal stored energy, while output limits require final configuration confirmation.

Technical Specifications

This 48 kWh listing represents 3 × 16.0 kWh battery modules. The supplied datasheet gives the 16 kWh module parameters and illustrates a 16-48 kWh series. Confirm the final multi-module interconnection, BMS settings, combined current limit, assembled dimensions and total mass before ordering.

The 12 kW figure is the inverter split-phase AC rating. Battery-only output is constrained by battery voltage and the applicable current limit; additional modules do not establish a higher inverter rating or automatically multiply the source-stated 200 A limit.

Protection thresholds and listed input/bypass values follow the supplied source. Final settings, application and circuit protection must be verified for the selected installation.

Installation and Configuration

The source lists a 760 × 240 × 450 mm inverter, 760 × 240 × 400 mm battery module and 760 × 240 × 50 mm base. Each battery module is listed at 125 ±5 kg, so the 3-module configuration requires planned handling and floor-loading review. Confirm final assembled dimensions and total mass with the selected system layout.

An appliance-style enclosure simplifies placement and keeps the system visually tidy, but electrical installation is performed by a qualified installer. Confirm floor loading, clearances, earthing, circuit protection, isolation, cable sizing and local requirements. IP20 specifies an indoor installation; the system is not presented as weatherproof outdoor equipment.

Frequently Asked Questions

Can this connect to a photovoltaic array?

Yes, the system includes MPPT solar charging. Design the strings for 120-450 V DC operation, 500 V DC maximum open-circuit voltage and 27 A + 27 A input current, with the specified 9 kW + 9 kW charging capability.

Does 48 kWh mean the inverter can always supply 12 kW from the battery?

No. The 12 kW rating describes split-phase inverter output. Available battery-only output depends on battery voltage, current limits, usable state of charge and the final module arrangement. Confirm the complete-system rating for the project.

Is the system ready for unqualified plug-in installation?

No. The stack and appliance-style enclosure simplify physical organization, but installation, protection, earthing and commissioning still require a qualified installer. Use an indoor location consistent with IP20 and the specified environmental limits.
