Can I go Off-Grid? The Truth about Energy Storage.
That''s why you have a 200 amp service to give you the ability to power your house all the time. Off-grid inverters typically have only a 25-40A output with the ability to surge to 50A for a short period. So you''ll need 4-5 inverters operating in parallel to provide the same power output that the grid can provide your house.
