Frequently Asked Questions
- 1 battery: 5.12kWh – small sheds, cabins and essential loads
- 2 batteries: 10.24kWh – workshops, rural cabins and extended backup

Actual requirements depend on your appliance consumption, inverter size and desired backup time.
One battery provides up to 95A continuous discharge, equal to approximately 4.86kW DC at nominal voltage before inverter losses. For a system expected to deliver 5kW continuously, we recommend using at least two batteries.
The battery supports CAN, RS485 and RS232 communication, but compatibility depends on the inverter model, firmware, protocol and cable pinout. Send us your inverter brand and model before ordering so we can help check compatibility.
Yes. The system can be expanded using identical batteries of the same model and specification. Battery voltage and state of charge should be closely matched before connecting additional modules in parallel.
No. This is a standard 51.2V rack battery and does not connect directly to EcoFlow DELTA extra-battery ports. An EcoFlow expansion cable or adapter is not included.
No. Solar panels must be connected through a compatible MPPT solar controller, hybrid inverter or inverter-charger. Correct cabling, isolation and overcurrent protection are also required.
The battery is rated IP20 and must be installed in a dry, protected indoor cabinet or suitable enclosed compartment. It can be used in professionally designed 48V motorhome or bus systems when the installation complies with applicable Australian electrical and RV standards.
The battery includes a five-year product warranty. Model-specific IEC 62619, UN38.3, FCC, CE, UL 1973 and RoHS documentation is available on request. Australian CEC listing or rebate eligibility should be checked separately before ordering for a grid-connected home system.
