Things like lawn mowers that use induction motors won’t work on DC. We don’t have all these households appliances made for DC at this stage. I have been on a yacht some time back and it had many appliances that was DC powered I think they do make many DC products for things like boats but they are expensive because it’s a small market. I don’t think an inverter system is the way to go because of the high consumption on the batteries. A pure DC higher safe voltage system will be a far cheaper option for the future. For now we do have lights that work perfectly from low voltage DC I spoke to someone yesterday that’s converting fridge/ freezers to work of DC. It might take time but DC is coming.
