Is this a Solar Assistant or eg4 issue ?

the AH capacity of my 6 eg4 lifepower batts should be 600 AH total. SA is showing 96 AH and it is making the percent charge/discharge calculation go crazy
in the first picture you can see that it thinks a 6233 watt charge is providing 119 percent per hour instead of about 19 percent/hour

in the next picture you can see the 96 AH total battery capacity, even though there are 6 batts, all above 95 AH each

{ am using the Narada r485 setting in solar assistant and have the kwh capacity at 30kwh in the advanced battery setting

Any ideas ??

EG4 would be the issue, the first battery should be doing the aggregate value calculation and providing that to the inverter as if it is a single battery ( or should be ). Others have report this working so I would suspect you do not have the settings or cabling incorrect.

my dips sw are set 2 at the top thru 7 on the bottom battery

Yes, your cables are plugged in wrong on the top battery. Solar assistant cable should be in the left socket and the cable going to your next battery goes in the right socket.

I changed the cables but it didnt seem to fix it,
right now it shows charging at 6600w and filling battery at 126 percent per hour.
I also rebooted solar assistant, didnt help,
do I need to turn off battery and back on ?

thanks
 
I had this problem, it showed 500ah instead of the 1090ah that I actually had. Updating to the most recent version fixed it. It's a beta version
