I'm hooking up a small battery back-up 3000 watt solar for back-up on my home if the grid goes down. I'm hard wiring it to a dry receptacle with two Coleman Air - B170 Diode Arrays (Blocking Diodes) @ 600 volts, 180 amps.
My question is when I checked to make sure the grid 120 volts was blocked I got the right readings off the + & - terminals on both Arrays. But will pick-up a 120 volt A/C for a very short time it then turns into 57 volts DC at the receptacle plug on the invertor side of the Array. Does it take the Diodes time to react, or are these so type of phantom readings? There was enough electric to run a small radio for about 1 minute and would run a light blub without ever going off.
The reason I'm hooking up to a dryer outlet is because I want to back feed my 200 amp sub panel (with the main breaker off). By doing so I should be able to run my home on its electric circuit without having to run electric cords all over the place.
I'd appreciate any help I can get.
Thank Apollo54
