I have 6 batteries in a cabinet. 3-LL V-2 top being the master. 4-6 are LL V1. All 6 batteries working and communicating fine hooked to the EG4 18KPV.
I have 3 Life Power's from another set up that I added. I simply connected communications cable to the last LL V1 battery in the rack and ran it to the EG4 communications Hub, then to the master Life Power and from there they are hooked to the other 2 making the 3 LP. From the last LP battery I ran 4/0 battery cables to the 2nd battery port of the 18 KPV, sense it has additional 200 amp breaker for battery saving time with buss bars or external breakers as my old cables were the right length. When I turned it all back on, there were no warnings or open loop issues from the 18KPV. The 6 batteries were at 64% and the Life Powers were about full and notice they were discharging as the 6 others were now charging. ( to make sure, this was done at night, dark out side, no PV) I figure this was ok that the SOC was equalizing. This morning when the sun made it to my panels I could see the SOC was relatively close to them all but did notice the Life Powers were about 9% higher but not completely charged yet. May be over time they will equal out. I also notice on my monitor app on my phone shows 6 batteries not 9 as it is now but I did not do a reset of the inverter yet. Do I need to?
I read on other battery threads of hooking up additional batteries starting with the last and using the EG4 communications Hub with the KPV as I all ready had this Hub. It all seems to be doing fine with no red flags showing but instead of hooking the LP's to the buss bars in the cabinet I ran them to the second battery port of the 18 kpv, and the other question is getting the 18kpv to show 9 batteries instead of 6.
