- | 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/ | + | 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.

Beware of phase rotation between the inverter and AC in. When wired in a rotation that is different to the programming of the Multis, the system will not accept the mains input and only operates in inverter mode.

A quick way to make settings in all units is the 'send to all units' feature. You'll see the option after making the changes to the first unit. | A quick way to make settings in all units is the 'send to all units' feature. You'll see the option after making the changes to the first unit. |
