Hey all,
Just had a new H3-Pro-20 + CQ6-L8 installed and noticed during Force Charge from grid it's capping at 17.1 kW. Was expecting closer to 20 kW given the inverter's rating.
Setup:
H3-Pro-20, CQ6-L8 (48 kWh)
3-phase, AusNet
Max Chg Cur confirmed at 50A on the LCD
Battery at ~50% SOC when observed
Force Charge via Mode Scheduler
17.1 kW works out to almost exactly 25A × 230V × 3 phases — which is the H3-Pro-15's rated output, not the 20. Looks a lot like a firmware default or ImportLimitCur value stuck at the wrong SKU.
A few questions for anyone running the same or similar:
What charge rate are you seeing on H3-Pro-20 with a CQ6 stack? Hitting nameplate, or also capped?
Anyone had FoxESS push a firmware update that unlocked higher charge rates?
Is there an installer-level setting I should ask them to check beyond the obvious ones?
I've emailed FoxESS AU support about it. Thought I'd ask here in case anyone's hit the same wall.
Cheers
