Questions and answers

Before you order

What is the battery’s actual storage capacity?
The battery has a nominal energy capacity of 5.12kWh, calculated from 51.2V × 100Ah.

Does it have 10.24kWh capacity?
No. A single 51.2V 100Ah battery provides 5.12kWh. Two identical batteries connected as an approved parallel bank would provide 10.24kWh.

Why is it described as a 48V system battery?
A 51.2V LiFePO₄ battery is commonly used in solar systems classified as 48V systems.

What does 98% depth of discharge mean?
It means up to approximately 98% of the battery’s stored energy may be available for use, subject to the manufacturer’s settings and operating conditions.

Can it be used for home backup power?
Yes. It is suitable for essential home loads when paired with a compatible inverter and correctly sized solar array.

Can it work with any hybrid inverter?
Not automatically. The inverter must support the battery voltage, charging settings and communication protocol.

Can the battery bank be expanded later?
Yes. Compatible units may be connected to increase storage capacity, subject to the manufacturer’s approved configuration.

How long will it provide backup power?
Backup time depends on the combined power consumption of the connected appliances. Lower loads provide longer backup periods.

Is professional installation required?
Professional installation is recommended to ensure safe wiring, correct protection and proper inverter-to-battery communication.
