5kWh 3.6kW All In One Energy Storage System for Residential Solar Backup
This 5kWh all in one energy storage system integrates a 3.6kW pure sine wave inverter, 25.6V battery pack, MPPT solar charger, LCD display and WiFi monitoring within one cabinet.
The system provides 5kWh of rated energy and 4.5kWh of usable energy at 90% depth of discharge, making it suitable for residential solar storage, essential-load backup and electricity self-consumption applications.
By combining the main power and storage components in one enclosure, the system reduces the number of separate units that installers need to position, connect and configure during residential energy storage projects.
The system can store energy generated by compatible residential solar panels for later household use when photovoltaic production is lower.
During a grid interruption, the system can supply selected lighting, routers, televisions, computers, refrigerators and other compatible loads within the inverter power limit.
Stored solar energy can be used to reduce direct grid consumption during periods when household demand is higher than current solar generation.
The integrated inverter and battery architecture can also support selected weak-grid or standalone power applications when the load and solar array are properly designed.

The battery provides 5kWh of rated energy and approximately 4.5kWh of usable energy when operated at 90% depth of discharge.
It can support compatible loads with combined continuous demand below 3.6kW. High-starting-current appliances must be evaluated according to their surge power and the inverter overload limits.
The system supports up to 5000W PV input and 18A input current. The MPPT operating voltage is 40–450Vdc, and the array open-circuit voltage must remain below 500Vdc.
Yes. The specified switching time is 10ms. Equipment compatibility should still be confirmed for loads with strict power continuity requirements.
Operating information is available through the integrated LCD, while USB communication and WiFi monitoring are supported for system setup and status checking.
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.
This 5kWh all in one ESS is suitable for solar installers, energy storage distributors, electrical contractors and project developers requiring a compact residential solar backup system.
Voltertech provides load confirmation, photovoltaic array matching, AC voltage selection, monitoring configuration, installation data, packaging information and quotation support according to project requirements.
