I finally got my CerboGX to see all of the components in our system: Multiplus II, 2x smart solar controllers, smart shunt. How is it possible to have negative power on Line 1??? FWIW, I was also seeing negative amperage numbers directly from the multiplus ii via the BT dongle... So, it's not the release candidate firmware on the CerboGX... Any ideas?
Bump...I'm still seeing this issue mainly when I get to the float stage. I've got no DC backfeed allowed. This is currently plugged into a none gfci outlet because it kept tripping the other with nothing connected but AC in. So either I still have something setup wrong or my MP seems faulty like the post above. Any advice would be great, thanks!
UPDATE!
I just did a no-shore-power inverting test and it worked great. However, after reconnecting shore power (50A), both the CerboGX AND Multiplus II (via BT) show 0W on line 1. I have an AC running on line 1, so this 0W is totally wrong.
Bad MP?
Sometimes a small in-balance in wiring can do this.
Also with some LOM detection settings you can occasional feedback, since it is testing for the / testing the grid.
