 For units in parallel: Both the DC and AC wiring needs to be symmetrical per phase: use the same length, type and cross-section to every unit in the phase. To make this easy, use a bus-bar or power-post before and after the inverter/chargers. Also, apply the same torque on all connections.
-With regards to AC fusing, each unit needs to be fused individually. Make sure to use the same type of fuse on each unit due to same resistance. Consider using mechanically connected fuses.
+With regards to AC fusing, each unit needs to be fused individually. Make sure to use the same type of fuse on each unit due to same resistance. Consider using mechanically connected fuses, so that if one trips, they all trip - leading to a clear fault.
