Has anyone ever set up Mycroft on an off-grid DC system ?
What I’m thinking off specifically is using a smart plug to allow recharging a DC battery on which the entire house electricity system runs. This way, it can allow for recharging of the DC battery during off-peak hours (which is cheaper). The AC devices (because most domestic household items can only be bought in AC-version) are powered from the DC battery through an inverter. Additional smart plugs can be placed in power sockets in which certain AC appliances sit (washing machine, dryer, dishwasher, …) thus allowing to run only if enough power is left in the battery (because you don’t want the battery to get too low either as it’s bad for the battery itself and you may want to reserve some extra power for other devices (lights, TV, refrigerator).
What’s tricky here is that many power companies no longer set specific times for off-peak and peak hours but rather use a digital meter in which any time during the day can be peak or off-peak, depending on the exact time and energy demand/supply ratio on the grid.
