Hi Guys,
Just put together a little cabinet to power my office and a couple other items during load shedding... We live in a rental so didn't want anything permanent, so hence going for the cabinet route. Another route could be to build a frame, did that at my In laws. (Pictures also attached)
Used the Following incase anyone else wants to ever do the same;

A plug, some caster wheels and good to go.
So as the picture show all is installed and working ran yesterday a load of around 200w for about 7 hours before i decided that was enough testing and plugged it in. So it works...
I have set the inverter to a user defined battery (Setting 14), Bulk to 28.4v (17), Float to 27.2v (18) and Cut off to 22.8v (19), as per recommendation from Esener, I see some sheet floating around with those numbers on, has anyone found other voltages to work better for this battery?
Now, what would be the best way for me to monitor the realtime SOC of the battery? Is my only option with what equipment i have a coulometer like below?

Now with the inverter charging the battery the charging light flashes yellow while its charging, but I haven't seen it go off, will the setup constantly "charge" once it hits float? or should the charginig light stop or go solid?
Thanks Guys
