6kW 16kWh Hybrid Solar Energy Storage System For Home Backup Power

6kW 16kWh Hybrid Solar Energy Storage System for Home Backup Power

Integrated Hybrid Power for Residential Solar Projects

This 6kW 16kWh hybrid solar energy storage system combines a pure sine wave inverter, battery storage, MPPT solar charger, LCD interface 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. It is suitable for home solar self-consumption, selected backup circuits and projects located in areas with an unstable utility supply.

By coordinating solar generation, battery energy and utility input, the system helps installers create a practical residential power configuration without arranging separate inverter and battery cabinets.

Hybrid Solar Energy Management

Suitable Home and Weak-Grid Applications

Residential Solar Self-Consumption

Stores compatible daytime solar generation for evening use and helps reduce direct utility consumption for selected household circuits.

Essential Home Backup

Can support compatible lighting, routers, televisions, computers, refrigerators, security equipment and other selected household loads during temporary outages.

Weak or Unstable Grid Areas

The combination of photovoltaic charging, battery storage and utility input is suitable for regions with frequent voltage fluctuations or intermittent electricity supply.

Home Office and Small Business Loads

The system may also support compatible computers, network devices, POS terminals, communication equipment and security systems within the rated output.

Battery Capacity and Backup Planning

The system provides approximately 14.4kWh of usable energy at 90% depth of discharge. Actual backup duration depends on connected load, inverter efficiency, battery condition and operating temperature.

A larger 16kWh battery extends expected operating time, but it does not increase the inverter output above 6kW. Capacity and output power should therefore be evaluated separately.

Electrical and Installation Specifications

PV Array and Charging Requirements

The integrated MPPT charger supports photovoltaic input up to 9000W and 27A. The MPPT operating range is 80–450Vdc, while the maximum photovoltaic open-circuit voltage is 500Vdc.

• Calculate the complete photovoltaic string open-circuit voltage before installation.
• Allow for solar panel voltage increases during low-temperature conditions.
• Keep total photovoltaic input current within the specified 27A limit.
• Maximum PV, AC and combined charging current is 120A.
• Confirm cable size, connectors, polarity and protective devices.
• Photovoltaic string design should be completed by a qualified installer.

Hybrid Solar Energy Storage FAQ

What does a hybrid solar energy storage system do?

It coordinates compatible solar panels, battery storage and utility electricity to supply loads, charge the battery and provide backup power according to the selected configuration.

How much usable battery energy is available?

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

What solar array can be connected?

The system supports up to 9000W and 27A of photovoltaic input. The MPPT operating range is 80–450Vdc, and total open-circuit voltage must remain below 500Vdc.

Can it support refrigerators, pumps or air conditioners?

Selected motor-driven appliances may be compatible when their normal operating power and startup demand remain within the inverter rating and overload limits.

Can the system be monitored remotely?

Yes. The product includes an LCD interface and supports USB communication and WiFi monitoring for operating information and system status.

Can the cabinet be installed outdoors?

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