It clearly says: “with a charger”. It took a long time. 24v at 3 amps. I could charge the array a lot quicker if I needed to, with multiple and bigger chargers and generators.
I saw “with a charger,” but I liked the mental image of you out there shining flashlights on your panels. Kind of like greenies putting windmills on their cars to generate “free” power.
Sound like you are prepared for the power to go out. Are you in Avista territory? We’ve got a house north of Coeur d’Alene and are away now hoping it doesn’t freeze up (no emergency generator).
