Summary

Problem to run both main saws when PV plant is not operational

Peak demand ~260kW, available power ~200kW

One ADF P100-150/480 plus one second life battery from Vovlo buses sufficient to support customers load cycle

Alternative solution, new feeder from closest utility distribution, ~100k€
