 ===== DC and AC wiring =====
-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.
 The VE.Bus cluster maintains a single 'global' status for SoC, DC voltage, and DC current. Every DC connection (on every Multi/Quattro and on every battery) has to be connected together to a single DC bus. Do //not// build systems with separated batteries on multiple (separated) DC bus structures connected to subsets of the Multi/Quattro units in the cluster. This will //not// work.
 Also beware of sizing the battery cable and jumpers between cells/batteries.
+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.
 For units in parallel: use one AC fuse for all units on that phase. Both on the input, and on the output. Multiple fuses which are mechanically connected together is ok: that is also one fuse.
