Plenty of topics, but haven’t found actual answer. 4 pieces us5000 1C, currently ~150A total max usage, 4 pairs of 2meter pylontech cablesets already available without extra cost.
Would you choose to connect a, b, or c option? Considering keeping pylontechs in balance.
Option a:
Option b:
Option c:
Plus cables would be connected to Hinode 660gh 200A fuses at the busbar, maybe even stacking 2cables to other sides of one end. And maybe even 125A mega in series to add power losses.
Thanks,
With option A, the two batteries in the middle would run out of SOC faster …
I use option B with my 6x US3000C … 2 x each on a Lynx outgoing circuit with fuse … Super balancing … With longer screws in the Lynx, 2 cable lugs also fit on top of each other
Option C is of course possible … but a 4x Lynx would then be completely occupied …
B or C make no difference to me
Only the reliability of “C” would be increased and you could disconnect each Pylontech separately …
How critical it is depends on how marginal the DCL is for providing for the systems needs.
If you are marginal, then individual connections to a bus bar is better. The arrangement on the bus bar is also important.
I use option c, but with my own build busbar with every us5000c (4 pieces) fused and a separate switch
