10 panels 3100 each roof east/west feeding East MPPT 1 and West MPPT2. To keep it short. 8 batteries 12-200ah NPD and 8 batteries 12- 200 ah Leoch.
Internal resistance NPD 3.0 and Leoch 3.2 . Both batteries are LP Series. How do i wire the 2 banks with each MPPT looking after one set of 8 and than linking to Inverter?
I know how to wire 8 to 1 MPPT or even possibly 2 MPPT . the original wiring for 1 bank Leoch was wrong as of installer wiring. Now i have to fix and was forced to add
8 more batteries to save guard the system if i end up having to dump off the 8 Leoch. Inverter 48v SNAT 6 KW. I need help . I study the Wiring unlimited pdf from Victron and http://www.smartgauge.co.uk/ on this issue. . thx for any help
