Buying a LiFePO4 battery for an existing — or new — inverter? Three things decide whether the pairing actually works: the voltage window, the current the inverter demands vs what the battery BMS can deliver, and the communication protocol. This calculator checks all three in about 30 seconds and hands you a brand-specific setup checklist. Built for homeowners, installers, and distributors sizing residential storage.
Planning reference only. Compatibility data is compiled from public compatibility lists (cutoff 2026-10) and can change with inverter firmware updates. Results are a match analysis, not a compatibility guarantee. Confirm with the inverter manufacturer before purchase; large or complex systems should be reviewed by a licensed installer.
Your system involves one or more of the following, which an online tool cannot fully assess:

Request a compatibility check for your exact inverter
The calculator checks voltage, current and protocol from public lists. Whether a specific battery works with a specific inverter is decided by a compatibility record: the exact battery model and BMS firmware, the inverter model and firmware, protocol, cable pinout and the settings used. Send us the combination and we reply in writing with what record exists, or what a check would need. This is a check request, not a compatibility guarantee; final settings are confirmed per project.
LJY Energy does not publish a list of compatible inverters. Compatibility is stated only for a combination that has a written record.
Send these details (* = needed to start):
Inverter brand * and full model string from the nameplate *
Inverter firmware version (main / DSP / communication board, if shown)
Voltage class *: LV 51.2V (48V class), HV stack, 12V / 24V, or not sure
Inverter communication port: CAN, RS485, both, or not sure
Battery model or capacity of interest * (e.g. “51.2V 200Ah rack”) and batteries per system, now and planned *
Battery profile already selected on the inverter, if any
Site: indoor or outdoor, minimum and maximum ambient °C
Destination country *, projects or units per year, company and your role (installer / integrator / distributor)
Notes: alarm codes, current wiring
We reply in writing with whether a compatibility record exists for that exact combination and, if not, what a check needs: a sample, the cable and the settings to try. No compatibility, approved-list place, price, lead time or certification is promised by this request.
