3.6kW 5kWh Residential Energy Storage System for Solar Backup Power
This residential energy storage system combines a 3.6kW pure sine wave inverter, 5kWh battery, MPPT solar charger, LCD display and WiFi monitoring within one compact cabinet.
It provides 5kWh of rated energy and approximately 4.5kWh of usable energy at 90% depth of discharge. The stored energy can support selected household loads when solar generation is low or grid power is temporarily unavailable.
The system is suitable for residential solar self-consumption, essential-load backup and home energy projects requiring an integrated inverter and battery solution.
Compatible photovoltaic panels can charge the battery during the day, allowing stored solar energy to be used when household demand continues after solar production decreases.
The 3.6kW inverter can supply compatible lighting, routers, televisions, computers, refrigerators and other selected household equipment during temporary grid interruptions.
Instead of using all solar energy immediately, homeowners can store part of the daytime generation for later household use and reduce direct grid consumption.
A specified 10ms transfer time supports fast switching for compatible essential circuits. Equipment with strict continuity requirements should still be checked before installation.
The system provides approximately 4.5kWh of usable energy at 90% depth of discharge. Actual operating time depends on load power, inverter efficiency, battery condition and operating temperature.
| Continuous Load | Estimated Backup Time | Example Load Level |
|---|---|---|
| 200W | Approx. 18–20 Hours | Router, lighting and small electronics |
| 500W | Approx. 7–8 Hours | Multiple essential household loads |
| 1000W | Approx. 3.5–4 Hours | Higher combined home backup load |
| 2000W | Approx. 1.7–2 Hours | Short-duration higher power demand |
The values above are planning estimates and are not guaranteed operating times.
| Rated Battery Energy | 5kWh at 0.2C and 25°C |
|---|---|
| Usable Battery Energy | 4.5kWh at 90% DOD |
| Nominal Battery Voltage | 25.6Vdc |
| Battery Operating Range | 20–29.2Vdc |
| Rated Inverter Output | 3.6kW |
| Output Waveform | Pure Sine Wave |

The MPPT solar charger supports up to 5000W photovoltaic input and operates within a 40–450Vdc range. Maximum photovoltaic open-circuit voltage is 500Vdc.
It is primarily intended for selected essential household circuits. Whole-home suitability depends on total continuous load, appliance startup power and the required backup duration.
The system has 5kWh rated energy and approximately 4.5kWh usable energy when configured for 90% depth of discharge.
Many household refrigerators may be compatible, but the compressor startup power must be checked together with the power demand of all other connected loads.
Yes. The product supports an LCD interface, USB communication and WiFi monitoring for checking operating information and system status.
The enclosure is rated IP20 and is not presented as a weatherproof outdoor product. Install it in a dry indoor or protected technical area.
Provide the installation country, household voltage, essential-load list, solar panel specifications, required backup time, order quantity and monitoring requirements.
This 3.6kW 5kWh residential energy storage system is suitable for solar installers, energy storage distributors, electrical contractors and project developers serving home solar markets.
Voltertech provides household load assessment, photovoltaic array matching, voltage selection, monitoring configuration, installation data and quotation support.
