Dual MPPT Home Power Hub 12kW 16kWh All In One ESS Energy Storage System

Dual MPPT Home Power Hub: 12kW 16kWh All In One Energy Storage System

Integrated Power Control for Multi-Circuit Homes

This 12kW 16kWh all in one energy storage system combines inverter output, battery storage, dual MPPT solar charging, communication interfaces and WiFi monitoring in one coordinated cabinet.

It provides 16kWh of rated energy and approximately 14.4kWh of usable energy at 90% depth of discharge. The 12kW pure sine wave output is suitable for projects that need to manage a broader range of household circuits than standard lower-power systems.

The integrated layout reduces the number of separate inverter, battery and monitoring components that installers must position, connect and configure during residential solar storage deployment.

All In One Energy Storage System Integration

Multi-Circuit Backup and Load Distribution

The 12kW output platform can support multiple compatible household circuits, but the final configuration should be based on actual simultaneous demand rather than the total rated power of every appliance in the property.

• Prioritize lighting, routers, communication and security equipment.
• Add refrigeration, computers and selected sockets after load calculation.
• Check startup demand for pumps, compressors and air conditioners.
• Keep nonessential heating loads outside the priority backup circuit.
• Reserve part of the inverter capacity for temporary load changes.

Electrical and Installation Specifications

PV Configuration and Commissioning

The specification lists a 27A and 9kW configuration when one MPPT is used and a 22.5A and 15kW configuration when two MPPTs are used. The final photovoltaic design should match the selected factory configuration.

The supplied parameter sheet contains two different MPPT lower-limit values: 80V in the feature summary and 6.0Vdc in the detailed parameter row. The final MPPT operating range should therefore be confirmed against the order-specific production datasheet before solar string design.

• Calculate string open-circuit voltage at the lowest expected temperature.
• Keep total open-circuit voltage below 500Vdc.
• Confirm the current limit for each selected MPPT configuration.
• Provide suitable DC isolators, cables, connectors and protection devices.
• Install the IP20 cabinet in a dry indoor or protected technical area.

All In One Energy Storage System FAQ

What is integrated inside the cabinet?

The system combines inverter output, battery storage, dual MPPT solar charging, local display, communication interfaces and WiFi monitoring.

Why is this system suitable for multi-circuit homes?

The 12kW output rating provides additional capacity for grouping several compatible household circuits after their continuous and startup demand has been assessed.

How much battery energy is usable?

The 16kWh battery provides approximately 14.4kWh of usable energy when operated at 90% depth of discharge.

Can the system be expanded later?

Parallel operation is supported. The approved quantity, communication settings, cable requirements and protection design should be confirmed for each project.

Can it be installed outdoors?

The enclosure is rated IP20 and should be installed in a dry indoor or protected technical area. It is not presented as a weatherproof outdoor system.

What information is required before quotation?

Provide the installation country, AC voltage, continuous and startup loads, required backup time, photovoltaic module data, MPPT configuration, installation environment and order quantity.
