Greetings!
I have been using my EG4 18K for a few months now - with AC coupling - and this week I have commissioned my DYI battery made out of 18 x 24V BYD used batteries.
After a few tests, I think the configuration is ok-ish.
The batteries are LiFePo4 with an average capacity of 2.75-3.75kWh each, which I calculated the whole pack to be 24-33kWh or 515-703Ah.
In the configuration I am limiting the charging to 56V - as recommended by the vendor - so I expect when the pack reaches that voltage, it stops charging, somehow?
But it doesn't. I get the voltage creeping up nearing 57V.
How does EG4 manages charging and how do I set a limit to stop charging?
My settings are:
AC Couple End Volt(V): 55V, however my battery is already at 56V and still charging??
AC Charge: OFF
Batt Charge Control: Volt
Charge Last: Disable
Solar panels on the GEN connectors with AC coupling
Battery type: Lead Acid (cant' tweak the Lead Acid Bett settings in the panel as any change results in error)
Batt capacity: 600Ah
Firmware version: F11B-0C19 (Mar 2024)
