12kW Dual MPPT Residential Energy Storage System with 16kWh Battery

High-Power Residential Solar Backup in One System

This 12kW 16kWh residential energy storage system combines high-power inverter output, battery storage, dual MPPT solar charging, system communication and WiFi monitoring within one integrated cabinet.

The battery provides 16kWh of rated energy and approximately 14.4kWh of usable energy at 90% depth of discharge. The 12kW pure sine wave output is designed for residential projects with larger simultaneous loads than standard 3.6kW or 6kW home battery systems.

It is suitable for villas, larger houses, home offices and residential properties requiring solar self-consumption, selected high-power backup circuits and support during an unstable utility supply.

Why Choose a 12kW Residential Energy Storage System

Residential Load Planning and Energy Use

The higher inverter output can support a wider residential load group, but the final backup circuit should still be designed around actual running power, appliance startup demand and required operating time.

Essential Household Circuits

Lighting, routers, communication equipment, refrigerators, security systems and selected sockets can be prioritized during an outage.

Home Office and Entertainment Loads

Computers, monitors, network devices, televisions and other compatible electronics may be included after their combined power demand has been calculated.

Motor-Driven Household Equipment

Pumps, refrigerators, air conditioners and other motor-driven appliances may require considerably higher startup power than their normal operating demand. Their surge requirements must be confirmed before installation.

Electrical and Installation Specifications

Dual MPPT Solar Array Planning

The solar charger uses a dual MPPT architecture. The technical data lists a 27A and 9kW configuration for one MPPT input arrangement and a 22.5A and 15kW configuration for the two-MPPT arrangement.

Because the permitted photovoltaic power depends on the selected input configuration, installers should confirm the final factory setting before completing the solar string design.

• Calculate string open-circuit voltage at the lowest expected site temperature.
• Keep photovoltaic operating voltage within the specified MPPT range.
• Keep total open-circuit voltage below 500Vdc.
• Confirm the current limit for each active MPPT input.
• Confirm cable size, polarity, connectors and DC protection devices.

Residential Energy Storage FAQ

Who is this 12kW residential system designed for?

It is designed for larger residential properties, villas, home offices and projects requiring more simultaneous backup power than a standard 6kW system.

How much battery energy is available for use?

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

Can it provide whole-home backup?

Whole-home suitability depends on the total continuous demand, appliance startup power and required backup duration. A qualified installer should complete a household load assessment before configuration.

Does it switch automatically during an outage?

The specified switching time is 10ms in APP or UPS mode and 20ms in generator mode. Equipment with strict continuity requirements should still be checked for compatibility.

Can the cabinet 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 for quotation?

Provide the installation country, household voltage, continuous and startup loads, required backup time, solar panel specifications, installation environment and order quantity.
