Battery is constantly discharging despite being plugged in.
Color GX is only showing it pulling 12w from the grid, shouldn't it be constantly keeping the batteries topped up when plugged in.

Battery not charging from AC
160ah lithium battery, bmv 702, easy plus compact inverter
Ok how to I get it to.maintain the battery?
Thanks
I didn't people who converted the van set everything up, was having issues with it not charging to 100 percent, they adjusted settings on bmv to cure that so onto the next issue the ac not maintaining the battery
This is from the manual about storage mode:
Less maintenance and aging when the battery is not in use: the Storage mode The Storage mode kicks in whenever the battery has not been subjected to discharge during 24 hours. In the Storage mode float voltage is reduced to 2,2V/cell (13,2V for 12V battery) to minimise gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to ‘equalize’ the battery. This feature prevents stratification of the electrolyte and sulphation, a major cause of early battery failure.
I wonder, do you have charging sources that the EasyPlus can not measure?. That will result in it's battery monitoring being very inaccurate and possibly the true state of charge is much higher than what is on your display. I experienced similar results with my setup before installing a BMV and I have several solar chargers that my multiplus2 don't know about. The Multiplus2 would say the battery is 82% but when I told it to charge, it would go to float and just put in a couple of amps. I know now why. MAYBE that's what goes on in your case. I would install a smartshunt or a BMV and use that as battery monitor instead. Much more reliable.
Oh, you have a BMV? Check settings - system setup - battery monitor and make sure the BMV is selected. Also - under battery measurements - make sure the BMV is visible and the EasyPlus is hidden. I don't know if necessary, but the battery monitoring function can probably be turned off with VEConfigure.
I would bet the shunt hasn't been 0 calibrated.
Voltage suggests your fully charged.
Remember SOC is a calculated figure so the inputs must be right to get the correct figures!
0 the shunt. Remove all loads and then use the 0 function
Check battery capacity is set correctly.
It displays 100 percent when fully charged and charges on the solar just don't understand why it won't just draw from.the ac while plugged on overnight
