VE.Bus Error 11
This error only applies to the MultiGrid and MultiPlus-II models: the inverter/chargers with a dual backfeed relay. For ESS systems, a grid-code is selected in VEConfigure, and then as part of grid-code compliance; the device verifies that its internal relays and measurement circuitry functions properly. When this test fails; Error 11 shows. Quite often, the error can be tracked down to an installation error (swapped Phase and Neutral wiring for example), but there were also some software issues; and the details of Error 11 not being visible was not helping. Today we are taking care of all that. A short list of related firmware releases:
