I live in an apartment and I’m worried about if I need to use this generator inside more than two days. How do you charge it if I buy it I don’t get much sun up here in the northwest and I can’t plug it in because it won’t be any power. What do you suggest?

Asked by John ·

Hi John, This generator doesn't need sun or a wall outlet. It runs on unleaded gasoline or propane (LPG), so as long as you have fuel, it makes power. The spec table lists 8hr of continuous running at 1/4 load and 2.8hr at full load on gas. With a 20 lb LPG tank, the listing says it can generate up to 20kWh, and propane is easier to store long term. Please don't plan to run it inside your apartment. It's a fuel-burning engine that produces exhaust, which is why it has built-in CO detection and shutdown. Check the user manual for where it can be safely placed. If you can't run a generator outdoors where you live, our team can help you find a setup that fits an apartment. Call 877-242-2792 or email info@shopsolarkits.com and we'll go over your options.
