You basically would lose that whole complete unit. What we have done now in this latest generation is we have split the unit up into four identical 1.1 kVA modules. So in total 4,400 V. But what this gives us is basically partial redundancy, so in case, for example, you have a single cooling fan fault, in the whole unit it would take down the complete 3.6 MW. In this case, you would basically just lose 25% or just 1.1 MW.”

YES, YES, YES, matrixed power blocks designed for emergency fall back redundancy and fault protection in 1.1MW inverter units. Set this matrixed power block design up as many selectable power blocks, design switching stations with (multiple) feeders from different centralized generation and dispatch regions and be able to shuttle energy from one feeder source to another feeder source with something like 75% round robin energy transfer and storage in huge utility scale ESS facilities allowing day ahead energy shuttling for a more robust grid.
