I have tested and I can go through the night oftentimes, if I did get good charge during the day depending on the weather. The load is just around 150W
If I don't and the grid is available. the grid will kick in, mostly an hour to daylight.
The issue will arise when batteries are low and the...
The measured voltage is usually quite close to what is displayed on the inverter.
I can retest with exact precision how much drop it gets under load, but it is in that range, quite significant.
but for this case, I guess that the voltage drop is what moves the voltage to a region under the set...
I think I might have figured out what exactly causes the issue, but not the solution.
I don't know if other users face this, but the voltage indicator varies greatly depending on whether the battery is charging or discharging.
for example, it can show 12.9V while charging, but if charging stops...
#20 and #21 only work when the grid is available and is connected to the charger as a source. i.e. during the day when the PV is on, these settings don't apply. Also if the grid is down, these settings don't apply.
#21, yes it does stop charging. when the grid is the only source available, for...
the setting is at 12.0V which is the highest allowable on the device.
The battery isn't dead. it's just that the inverter seems to want to cut it off from the inverter. infact all the while that it is flashing the low voltage error, it is usually charging as well.
