I have 800 watts of solar and a 1200 watt pure sine wave inverter with a power jack, I have 800 watts of solar and a 1200 watt pure sine wave inverter with a power jack, do you see a problem with this? If so could you tell me what? Thank you Kevin.

Please clarify - you have 800 watts of DC being supplied by solar cells? At what voltage? As long as the voltage meets the specification for the invertor input it should be OK. Most invertors work with input of either 12 or 24 volts DC.
