I have a sunny boy 5.0kw inverter and want to know what my total usage if for my house. how do i set this for the inverter to read the supply meter in my meter box

no idea as to the wattage used in your house as it varies with the equipment
you have to go around and add all of the wattages in use your self ---lights each, fridge , freezer , stove , fans each , air conditioners each, toaster , microwave etc and add then all up that will show the total wattage in use for the house
then you can put that in your supply meter

I suspect strongly that it has an interlock switch on the front panel, and someone has opened the panel and failed to fully close it back up so it's weathertight.

Fault lite blinking

Make sure the ground from inverter to frame is intact. Make sure the positive and negative connections are clean and tight. If this all checks out, disconnect power to the unit for 1 hour and let is reset. If it still shows a fault then you really need to send it back to the manufacture for repair.

I have a vector 3000 watt inveter red fault light is on, wont power a 6.5 amp fuel pump

Check that ground is correctly connected. If nuetral is provided, ensure it too is connected. Your total load is 780 watts. Check power in and ground out of the supply side. There may be a fuse in the inverter on the output side also, replace if necessary. If fault light does not go out after these checks, you will need to contact Black and Decker who manufactures the vector series now.
