The cottage has solar electricity via an inverter 230V. If the battery level gets too low, I charge them with the Blue Smart IP22 Charger 30A charger, in this situation the entire solar system with inverter is separated from the cabin's electrical system with a mains changeover switch and the generator is used. When I plug the charger into the socket while the generator is charging, the cabin lights start flashing like strobe lights. Where could the problem be?
