I am considering solar power. But I need to power critical loads from the solar panel directly when there is a power failure. A conventional transfer switch would isolate the inverter from the line.
A small UPS could be used to convince the inverter that AC power is available. The inverter should then be able to supply power directly to the loads selected manually by the breakers in the power panel, just as if it were sending power back to the power company. It should not be necessary to have additional batteries, so long as I accept that the loads will be powered only when the sun is shining. A transfer switch and UPS can be obtained for about $500. Is there anything technically wrong with this approach?
