Larger installations mostly are spread over wider areas. If you have to restart your standalone system you run the risk in getting hit directly with the full load from all consumers.

Therefore the consumers have to be added to the “grid” in some kind of sequence. We intend to install power-on delay relays within your 400V subpanels. Their capacities will depend about 70kW or 100A, their individual delay will be programmed individually; the priority will be determined by the client.
