So I ended up getting a brand new skybox and was going to take the loss on the used one but the new inverter has a bad mains relay that welded closed. They are sending me another top piece so I took apart the 2 dead inverters before I sent them to the recycling center. Removed the main board to...

I have looked and can't seem to find a clear answer. Or maybe I'm terrible at asking questions :) I have an enphase solar system with iq7 micro inverters. I also have a 15KWh battery bank that I want to add as a back up and have the battery power the house at night when it isn't producing...

Will an MPP Solar LVX6048WP do the job?

Don't suppose anyone ever traced out some of the boards or got hold of a schematic?

Very helpful. i noticed all of the test points on the backplane the "support" tech at outback would not tell me what they were or where they were connected to. I have bought a new skybox which a local power store had as a last in stock, when I get it mounted I'll A/B the test points and see...

Just a note. You're using a 12V regulator for the power supply but the voltage from the AFCI is 5V (at least it is on mine). Other than a filter cap the regulator shouldn't be necessary

Connected the grid and no difference so it isn't that. I think the 12V aux settings are in the skybox pages. Which multi connector do you mean? The AFCI 4 pin or that black/orange phoenix connector? And one other thing what revision is you main board? Mine says Rev E it's on the left near the...

Thanks so much for this. I just got a skybox also missing the BOS. I'm running AC coupled but didn't know the whole things will not run with the arc fault. Saves me a whole lot of time hooking my scope and logic analyzer to the thing.

Yeah, rsd jumper is in

I only have the batteries connected, maybe need the grid connected too?

No 12V at the Aux power tried setting it to RSD and AGS an didn't see any power. I am using an Arduino. Going to do some checking on the board I built, maybe the transistor isn't grounding pin 3

actually, i went back and checked and its 3 Volts between pin 1 and ground. If I run the test it does jump up to about 7 volts I'm guessing pin 2 is a pulled down input somewhere and not true ground. only other thing I can think is I have the pins backwards. looking directly at the connector its...

I'm guessing I have a brick on my hands. I powered the Arduino from the beagle board and added some code to flash the Arduino LEDs when pin 4 pulses came in. I could get a pass in the solar block but a power cycle brought the arc fault back up. I could also go into the skybox block and clear all...
