AMKJ Posted September 6, 2017 Share Posted September 6, 2017 Hi all, I need some help with my Axpert inverter settings for my Sonic NPS 100-12 batteries. My setup is as follows: 9 x Renesolar 300w panels 1 x Axpert 5kva inverter 48v 16 x Sonic Gel (12v 100ah each) batteries (4 stings of 4) 1 x Battery monitor BMV702 My current settings on my Inverter are as follows: 1 - SbU 2 - 10a 3 - UPS 4 - 5d5 disable 5 - AGM 6 - Ltd disable 7 - ttd disable 9 - 50hz 11 - 10a 12 - 49v 13 - 56v 16 - OSO 18 - bON 19 - tEP 20 - LON 22 - AON 23 - bye enable 25 - FEN enable 26 - 56.4v 27 - 54.0v 28 - SIG 29 - 42.0v 30 - ONE 31 - SbE enable Now my question....... What must setting 2, 5, 11, 26, 27 set to? According to my batteries I believe it must be set to: 2 - 40a 5 - USE 11 - 25a 26 - 57.6-59.6 27 - 54.4-55.2 is this correct?

Chris Hobson Posted September 7, 2017 Share Posted September 7, 2017 Initial current of 25A would translate to 100A over 4 strings of batteries. So this may take a bit of management on your part. Program 2 100A. Porgram 5 USE Program 11 60A. Program 26 57.6V Program 27 54.4V Program 16 SNU Program 1 UTI (for early morning as the sun gets up). Now your battery manufacturer expects 100A initially and the only way to achieve that is to combine utility and solar. As soon as the charging rate drops to what the panels can cover one would switch off the utility. I have seen a couple of the AGM/Gel manufacturers recommend a high initial charging rate but have yet to find the reason for this. Quote Link to comment Share on other sites More sharing options...
AMKJ Posted September 7, 2017 Author Share Posted September 7, 2017 Thank you Chris for the reply. I have changed my settings as you recommended and will monitor closely. Quote Link to comment Share on other sites More sharing options...
Chris Hobson Posted September 7, 2017 Share Posted September 7, 2017 You will have to monitor carefully and switch from Program 1 SBU to UTI so that you can give it that "jumpstart" it requires. Find out from the supplier what that high initial charging does for the battery and how important is it. Quote Link to comment Share on other sites More sharing options...
Jazzy Posted June 4, 2019 Share Posted June 4, 2019 I think it moves around the gel in the battery there is term for it...slipped my mind. I am running gel batteries AllGrand, and bulk charge at 58.8 volts, float charge at 54.4, and dod is at 44 volts. User set up... I have chosen SBU, and run my pool pump and geyser of it with 12 panels, and two strings 150 AH, 48 volt set up...thus far I have managed to stay of the grid for 22 hours, two hours is just to keep the electricity company going... Will be going Lithium PylonTech 9 KWH set up... Busy testing the difference in all of these things... Quote Link to comment Share on other sites More sharing options...
