I have what I imagine is a bit of a unique situation. My house is about to be renovated which involves disconnecting the main power for 4 months to allow for a garage to be demolished and rebuilt.
I'm exploring ways we could live in that house for 2-3 of those months on a low-power-consumption diet. Ie, no washer/dryer, no dishwasher, no air conditioner, etc. One lifeline I have is an extension cord running from my neighbour's house.
Option 1 is to simply live off the extension cord. Run the fridge, our wifi, and charge a few laptops as needed.
Option 2 is to purchase an electric powerstation product such as GoalZero's YETI meant to support camping or offsite construction, leave it plugged into the extension cord, and run limited power off this. This gives me time at night to charge it up, and opportunity to use more than 15 amps of draw during the day to power a microwave, desktop computer, etc.
Option 3 I'm looking to consider is getting a 13kwh powerwall. It could form the basis of a future solar setup, offsetting some of the initial costs. This would avoid us running extension cords all over the house, and we'd just need to limit our usage based on state of charge.
Is there a way I could potentially run a PowerWall, and charge it using an extension cord running 12Amps or so? It could charge at night, and be used during the day?
