Plenty here do. I've been using 6 of them since last year, very happy with the setup, but you will need solar if you want to avoid generator - you can safely draw down the batteries to 90% (I don't go beyond 80%), but they need feeding. For the microwave, you will need a solid inverter and beefy wiring.
I started a separate thread on cold weather charging of LifePO4 batteries. I built an insulated box (R10 styrofoam), with a waste tank heating pad and aluminum plate under the batteries to keep them warm. I also added a Victron temperature sensor to my equipment so that the MPPTs will not attempt to charge below 5C. Discharging is not the issue, they cannot be charged below 0C or you will damage them.
