Hivolt 380X
This is the answer when the grid connection is the problem and waiting is not an option: 800 kWh on wheels, 300 kW out over CCS2, no permit, no digging. It also does peak shaving on a site that already has power, and it can work with a hybrid generator. The cells are LFP, rated for 8,000 cycles and more than ten years, so the cost per charge depends mostly on what you pay for the box. No price is published.
