Inverter Battery Compatibility Calculator

Free tool — no signup, instant results. Your inputs never leave your browser.

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.
