Deye F60: Battery Over/Under Voltage (BMS Protection)

Updated June 2026 · Reviewed for technical accuracy · ~2 min read

F60 means the battery's own protection system (the BMS) reported an over-voltage or under-voltage condition and stopped charging or discharging to protect the battery. This is the battery defending itself. It needs to be taken seriously rather than just reset.

What usually causes F60

  • Under-voltage: the battery was discharged too low (see also F56).
  • Over-voltage: a charge setting or a cell imbalance pushed voltage too high.
  • A charge-setting mismatch between the inverter and the battery profile.
  • An aging or out-of-balance battery that needs the maker.

What to do, safely

Before you start Only use the battery's on/off switch and the inverter breakers. Don't touch the battery power terminals.
  1. Check the battery's own display or app if it has one, to see whether it's flagging high or low voltage.
  2. For under-voltage, allow the battery to charge from solar or grid (if configured), then restart.
  3. Confirm the battery profile selected in the inverter matches your actual battery, since the wrong profile can drive voltage out of range.
  4. If F60 persists, stop and contact your installer or the battery manufacturer. A protection that won't clear points to a real battery condition.
When to call a professional F60 is the battery's safety protection. If it doesn't clear after the battery is at a normal charge with the correct profile, the battery or its BMS needs your installer or the manufacturer. Don't keep overriding a battery protection.

FAQ

Will F60 damage my battery?

The opposite: F60 is the battery protecting itself by stopping charge or discharge before damage occurs. The point is to fix the cause (charge level or settings), not to bypass the protection.

The battery went very low and now shows F60.

That's an under-voltage protection. Let it charge back to a normal level (solar or grid, if allowed) and restart. If it won't recover, contact your battery maker.
