The freedom 10 and freedom 20 series are very good, well built
But hard to find a shop for repair
But before you give up hope
Check the push button circuit breakers on the front , push on them to reset them
Also unplug the remote cable
Then turn the unit off,using the manual switch, wait a few minutes and turn it back on
Some times the control circuit needs to be reset
Several members have replaced the inside control panel
When mine died, it burned a relay mounted on a circuit board and burned the board, my fault I had too much load on the pass thru circuit
Don't plug electric heater or heavy battery charger, into the circuits powered by the inverter
When on battery inverter will shut down on over load
BUT when on shore power or generator you can over heat the internal pass thru relay contacts using continuous heavy current loads
