Unfortunately, large-scale CAES plants are very energy inefficient. Compressing and decompressing air introduces energy losses, resulting in an electric-to-electric efficiency of only 40-52%, compared to 70-85% for pumped hydropower plants, and 70-90% for chemical batteries. The low efficiency is mainly since air heats up during …

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.
