8kWh 3.6kW All In One Energy Storage System for Residential Solar Backup
This 8kWh all in one energy storage system combines a 3.6kW inverter, battery storage, MPPT solar charging, system control and monitoring functions within one integrated cabinet.
It provides 8kWh of rated battery energy and approximately 7.2kWh of usable energy at 90% depth of discharge, making it suitable for residential solar backup projects that require longer operating time than smaller-capacity systems.
The integrated structure reduces the number of separate components that installers need to position, wire and configure, while supporting solar charging, grid charging and selected backup circuits.
Suitable for selected lighting, routers, televisions, computers, refrigerators, security equipment and communication devices during temporary outages.
Stores compatible photovoltaic generation for later use when household demand continues after daytime solar production decreases.
Can support compatible POS terminals, network devices, computers, CCTV equipment, lighting and other low-power business loads.
The combination of solar input, battery storage and AC charging is suitable for projects in areas with unstable or intermittent utility electricity.
The system provides approximately 7.2kWh of usable battery energy at 90% depth of discharge. Actual operating time depends on connected load, conversion efficiency, battery condition and operating temperature.
Motor-driven equipment such as refrigerators, pumps and air conditioners may require higher startup power. Both normal operating demand and starting demand should be checked before installation.

The MPPT solar charger supports photovoltaic input up to 5000W and 18A. The operating voltage range is 40–450Vdc, with a maximum photovoltaic open-circuit voltage of 500Vdc.
Battery capacity determines expected operating time, while inverter power determines the maximum continuous load that can be supplied at one time.
The system provides approximately 7.2kWh of usable battery energy when operated at 90% depth of discharge.
Selected motor-driven appliances may be compatible when their normal operating power and startup demand remain within the inverter output and overload limits.
The system supports up to 5000W and 18A of photovoltaic input. The MPPT operating range is 40–450Vdc, and the open-circuit voltage must remain below 500Vdc.
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 product.
Provide the installation country, AC voltage, connected-load list, appliance startup power, solar panel specifications, required backup duration and order quantity.
This 8kWh all in one energy storage system is suitable for solar installers, energy storage distributors, electrical contractors and project developers requiring longer backup duration within a compact integrated system.
Voltertech provides load assessment, photovoltaic array matching, AC voltage selection, monitoring setup, installation data, packaging information and quotation support.
