Fox ESS EP11 10KWH battery shuts itself
Posted: Wed Aug 26, 2026 8:36 am
Hi - my EP11 10KWH battery with H1 Inverter has shown error 234 and 194, with the inverter screen showing Battery voltage error and the battery after 30 mins of this shuts itself off and powers down. All firmware updated , latest app version.
I've cycled several start up and show down sequences per guidance from AI, have we any views as to what this can be - looks like a straightforward battery fault to me where the BMS is just shutting it off as its performing outside safe parameters. Any views or advice , I have raised a ticket with the installers as still under warranty
