Hi Everyone,
So I have already had help with my easysolar 12/1600 which is paired with a Lithium 300ah battery with built in Bluetooth BMS.
My issue is the charger constantly getting the battery to full charge, then turning off, the voltage drops as it isn’t being charged and then the charger kicks back in and repeating the cycle. This in turn means I can’t stop the lithium BMS from having cell over voltage protection kick in and when that happens it cuts power to the entire van for about a second. Is there a way to stop this?
I have been adjusting the parameters within ‘AC Input Control’ to get the charge from the AC input to stop charging at 14.1V instead of 14.4V and then come back on when battery percentage is at 85% but this cuts the power to the air conditioner on AC OUT 0.
Is there a way to set the ac input charge to stop charging at a battery percentage rather than a voltage as charge voltage is not representative of the battery full voltage.
I have also tried having the ‘AC Input Control’ off and under ‘Charger’ setting the absorption to 14.1V but this just meant the original issue of charge to 100% cut off, voltage drop, charge back on etc until the BMS freaked out, happened again.
am I missing something or do I just have to lower the absorption voltage to nearer 13.6v which is where the battery sits at 100% when not being charged?
