Reply To: Do V5 battery groups in parallel need to be the same size?

[ruisseau]

I plan on using the Sol-Ark 15K-2P, single inverter. The client needs between 25 and 40kWh of reserve, so between 5 and 8 V5° batteries. I was going to offer the V-Boc-IC for a safe and cleaner look.

6 batteries is easy, two groups of 3, in two enclosures

5 batteries would mean a group of 3 + a group of 2, in two enclosures (?)

7 batteries would mean a group of 3 + two groups of 2, in three enclosures (?)

8 batteries would mean two groups of 3 + a group of 2, in three enclosures (?)

But I was wondering if I should use the parallel busbars in each enclosure, and then have each group joined on external busbars (i.e. Victron Lynx series) with the inverter, or have each battery cabled individually onto (larger) busbars.
