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.

The argument against the idea of off-grid NZEB is that energy storage technologies are not mature enough to serve the function of grid connection to maintain the reliability of power supply. Thus, designers usually propose oversizing the renewable energy sources in order to ensure there is no loss of load due to unpredictable weather condition.
The levelized cost of hydrogen (LCOH) is a widely used economic indicator.
