Inverter Model: H1-5.0-E-G2-WL
Inverter Serial Number: 605H5020629xxxx
Battery Model: Fox ESS 11kW Stack
Issue Description:
I am experiencing a persistent firmware state-lock bug on my Gen 2 single-phase system. When utilizing the Mode Scheduler for an overnight Forced Charge (02:00–05:00), the inverter fails to transition back into Self-Use mode once the time window expires.
Even when outside the scheduled time window, or when an explicit Self-Use block is programmed, the inverter holds the battery frozen (e.g., at 45%) and forces the property to import 100% of its load from the grid. This issue persists even after deleting the schedules entirely, requiring a full hard DC/AC power cycle to temporarily clear the register.
Also the battery will now not charge above 45%
Does anyone know if there is an easy fix. I have created a support ticket but dont know how long they will take to respond.
Thanks
