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
What firmware are you running on your H3 Pro?
If you DL the latest Au data sheet you will see a new footnote.
[3] Charge/discharge power limit is 17kW.

On the older data sheet footnote [3] was not present.
https://www.fox-ess.com/Public/Uploads/ ... 251021.pdf
There is still a dirty big circle on the first page proclaiming 'up to 30kW charge/discharge'.
This is now clearly false advertising.
It has crippled any inverter over 17kW.
