is this panel pos or neg ground

I'm not sure, but if you check the website I'm sure the specs should have that info.

My installation is grounded to the negative side of the battery, I recall the manufactures installation instructions showed a negative and a positive ground diagram so you should be able to do either.

sure, hook them up parrallel. mine was wired wrong, the pos was black not red, please check polarity with multi meter before installing.

Usually the center connector is Positive. Use your DMM to determine the polarity.

Sorry! Still didn't install yet! But I would say it's not grounded or wired properly!

Mine was clearly marked. From left to right (looking at terminal end of board:Gnd ( battery negative)motor (load) negative -motor (load) posative +Battery posativeHope this helps

Vincent, I have been trying to get someone to hook it up for me. I had the wires run when I built the house a few months ago. When i got the unit, one of the monitor screen was pushed back, I don't think the quality is very good. Or at least their QC. Sorry this doesn't answer your question. I may try to sell mine off because I don't feel that they will back it up with a warranty. I guess we get what we pay for.

Sounds like you have a ground issue somewhere, I haven't experienced any hum or distortion

Sounds like you have floating ground due to incorrect wiring of circuit. If you have good working knowledge of home wiring, use voltage tester to assure positive colored wire is positive and check for continuity between ground wire and assured ground (usually bare copper wire). If any doubt exists or you're not knowledgeable in electrical wiring and circuits - Get a professional electrician to check wiring and installation of switch. Never take chances, improper wiring can result in fires, loss of property and lives.

That is the neutral bar. Code requires sub-panels to have a separate ground and neutral bars.

I would make sure the receptacle is working right and is wired and polarity is correct. Dennis

If you look at the picture more closely, you will see that wording is near a small LED light, and that text tells you what that light means. In other words, if the light comes on, then there is a problem with your ground. This is something that is quite a nice little feature, in case some idiot wired your house incorrectly, it will tell you that the ground isn't working. And so you will want to have an electrician look at your wiring in your house. Preferably one who is not the idiot who did not wire the house properly.

Yes it is. I had to reverse mine. Very simple, as I remember there were a couple of screws to remove to switch the panels. Less than 5 minutes.

With a standard 12v DC adapter. Look on the PCB and you will see a + and - sign indicating the polarity.

Negative, yet there is an input receptacle with NO SPECS as to polarity and voltage needed, as well a missing current spec needed when multiple items are connected. Closer inspection of item shows no specs ON the item either, but it appears that an area below the receptacle has been sanded off, as if the specs were removed, as was the model info. Weird.. Inspection was done with lighted magnifier I used at NASA to inspect pins. sort of like owning a 7-stall barn that will only hold 4 horses at best ;-)

Check all the cables. Make sure the switches are hooked up properly. It's easy to knock 1 or 2 loose without seeing it. If all is hooked up properly and power applied to the PSU it's possible there is a short / ground.

See Karlberg's comment. Also, both studs are for Positive inputs. There are no Negative (ground) terminals.

I am guessing "NO" since I originally had the wiring polarity hooked up backwards and didn't have a reading.
