Battery Architecture
5kWh Battery Pack and BMS Arrangement
The battery system uses LiFePO4 storage packs and battery management equipment. Pack connection and protection details follow the supplied assembly.
Battery Packs
The product information identifies 5kWh battery packs. Electrical connections must follow the specified battery arrangement.
Battery Management
The BMS supervises operating conditions and protection. Communication settings must match the connected equipment.
Enclosure and Access
Allow suitable clearance for positioning, cable connections, ventilation and maintenance.
Inverter Integration
20kWh Battery and Hybrid Inverter Compatibility
Inverter compatibility depends on voltage, battery current limits and BMS communication. The inverter must support the selected battery configuration.
DC Voltage Range
The inverter's battery connection must support the operating voltage range of 40–58.4V.
Discharge Power
Available power depends on battery voltage, current limits, inverter efficiency and the operating conditions.
RS485 and CAN Communication
Confirm the required BMS protocol and supported inverter model. Matching interfaces alone do not ensure compatibility.
Backup Function
Backup power requires an inverter with a suitable backup output and switching arrangement. The battery itself supplies DC power.

Buyer Questions
20kWh Battery Storage FAQ
- What is the nominal voltage of this 20kWh battery?
The battery has a nominal voltage of 51.2V DC and an operating range of 40–58.4V DC.
- How many battery packs correspond to 20kWh of storage?
At 5kWh per pack, 20kWh corresponds to four packs. The electrical connection arrangement depends on the supplied system design.
- Can the 20kWh battery work with my hybrid inverter?
Compatibility depends on the inverter's battery voltage range, current limits and BMS communication protocol. Provide the inverter model for matching.
- How long can a 20kWh home battery power a house?
Runtime depends on usable energy, electrical demand and inverter losses. A constant 2kW load would use 20kWh in 10 hours before accounting for system losses and reserve capacity.
- Can this IP55 battery be installed outdoors?
IP55 provides protection against limited dust ingress and water jets, but outdoor installation still depends on the manufacturer's installation requirements and site conditions.
