7.68kWh 4kW All In One ESS / Solar Energy Storage System With 5kW PV Input

7.68kWh 4kW All in One Solar Energy Storage System with 5kW PV Input

This all in one solar energy storage system combines a 7.68kWh LiFePO4 battery, a 4kW inverter and a 5kW photovoltaic input section inside one floor-standing cabinet. It is suitable for homes, small offices, shops, communication sites and controlled off-grid power projects.

The integrated design reduces the need to select separate battery and inverter enclosures. Solar modules, AC distribution equipment and external electrical protection are configured according to the project.

4kW Output for Selected Loads

The system provides 4000W of rated output and a listed peak capacity of 8000VA. It can be evaluated for lighting, refrigeration, computers, routers, televisions, security equipment and other compatible residential or small business loads.

The 8000VA value is intended for temporary startup demand rather than continuous operation. Refrigerators, pumps, compressors and other motor-driven equipment should be checked for both running power and startup requirement.

5kW Solar Input with Wide MPPT Range

The photovoltaic section supports up to 5000W of PV input. Its MPPT operating range is listed as 60–500Vdc, with a maximum MPPT input voltage of 500Vdc.

The PV string should be calculated from module open-circuit voltage, operating voltage, temperature coefficient and the number of panels connected in series. Cold-weather open-circuit voltage must remain below the system limit.

The 90–280Vac input range also allows the system to use a compatible AC source when solar production is insufficient or battery charging is required.

7.68kWh LiFePO4 Battery Reserve

The integrated LiFePO4 battery provides 7.68kWh of nominal stored energy. It can retain daytime solar generation for evening use or maintain a planned reserve for selected equipment.

Battery capacity and inverter output should be evaluated separately. The 4kW inverter rating determines simultaneous load capability, while the 7.68kWh battery rating influences the potential operating period.

The brochure lists more than 6000 battery cycles. Actual performance depends on operating temperature, charging settings, depth of discharge and system use.

Integrated Display and Auxiliary Power

An LCD provides local access to supported system information, while WiFi is available as an optional monitoring function. The required monitoring configuration should be confirmed during quotation.

Auxiliary connections include a 12V 3A DC output, a 5V 2.4A USB port and a 5V 2.4A Type-C port. These outputs are intended for compatible low-power devices and remain separate from the main AC load supply.

4kW Integrated Solar Storage FAQ

What type of project suits the 4kW system?

It is suitable for projects with selected home, office, retail or communication loads that remain within the 4kW continuous output rating.

Does the 8000VA peak rating increase continuous output?

No. Continuous output remains 4000W. The peak rating is intended for temporary startup demand.

How should the solar-panel string be selected?

Use the module voltage and temperature data to keep the operating string within the 60–500Vdc MPPT range and below the 500Vdc maximum.

Can the DC and USB ports power the main household loads?

No. They are auxiliary low-power outputs. Main appliances use the system’s AC output.

Which information is needed for system selection?

Provide the load list, startup power, daily energy use, PV module data, AC standard and required backup period.
