I have the Giandel 2200w inverter and the Victron 100/50 controller with 2 SOK 100 amp 12 Lithium batteries. 4 100 watt solar panels in series with max voltage of about 89 volts. When the batteries are going into Absorbtion mode the voltage goes to the setting of 14.6. I did see a max voltage of 15.2 I think in the history. Problem is when it goes into Absorbtion the inverter gives a OverVoltage fault. I turned the voltage setting down to 14.4 and it seems the problem has gone away. This inverter says max voltage is 16 +/- .5 volts. Anybody else have any experience with this.
Overvoltage on inverter when hitting Absorption voltage

Yes equal is disabled. And yes the 14.4-14.6 is the good range for LiPO. Just seems strange that the inverter is good to 16 +/-.5 and is having issues with 14.6. Wondering if I’m getting spike momentarily to hit 15.5 plus to trigger it. Totally new to this and am relying on my Holiday Inn stay to do this!
It think the disconnect and reconnect are labeled wrong. Disc should be >14.6 and reconnect should be <14.4. So even though they list the absorption voltage should be 14.6, the disconnect is also 14.6. So you could be correct. So setting it at 14.4 would avoid that, I hope.
