Hi, I hope someone can help me as this is a bit worrying!

I've set up my inverter and battery to run line mode, no solar, just plugged the inverter into a wall outlet connected to its own 20a circuit on the DB. The cutoff to battery works fine, as well as the flip back to mains power but the battery is not being charged. After a night running in bypass the battery appears to have been depleted even though it wasn't being used. 

I've attached 2 pics of the inverter  - screen and techspec

 

Here are my settings:

 

01- output source priority	UtI
02- max charging current	20A
03- ac input voltage rante	APL
05- batter type	USE
06- auto restart when overload	Ltd
07 auto restart when over temp	ttd
09- output freq	50H
10- output voltage	230v
11- max utilit charging current	20A
12 – setting voltage point back to utility source for SBU ad Solar first	N/A – left as def
13- setting voltage back to batter ode with sdbu or solar first	N/A – left as def
16- cahrger source priority	Cut
26- Buk chargine voltage	14.3v
27- floating charging voltage	14v
29- low dc cut-off voltage	11.5
no equalization settings changed. Default to ‘no equalization’

 

Have I made a huge mistake on the settings? Please help!

 

thanks in advance,

ross

battery screen info says it's at 10.7v

I see setting 16 keeps reverting to OSO, no matter how many times I set it to CUt. all my other settings have been kept.

Do you have PV coming in?

Press the up and down arrows and check what is the PV voltage from your strings. It looks like no PV available that's why it refuses the setting OSO.

Further if it goes back to Util for charging then Util should charge batteries and it is also not working.

hi. No I have no PV yet I'm just using it as a ups for now. I saw 16 kept reverting to OSO from CUt so I instead changed it to CSO. The battery immediately started charging so that's good. Do the rest of the settings look ok for the s120 battery?
