New FP1 not inverting, but all else working

Postby Jpro556 on Sat Dec 01, 2018 12:42 pm

Hey all,

I just installed a new FP1 in a remote off grid application, with a 14kw Kohler generator.

Everything is working great, except, the inverter won't invert. Generator bypass gets me my AC power.
Where the mate has the option to turn the inverter on, off, or search, the inverter is off, and the mate buttons can't change that. Nothing happens when pressing on or search. Again, the inverter charges just fine as far as I can tell so far.

1st question I assume I'll get is about the jumper, yes, I set the inverter jumper to ON.

I went through the profile and configuration wizard, but wasn't satisfied, so configured everything directly through settings according to battery and generator requirements.

I lightly checked many wiring connections, and nothing was loose to the fingers. I know I didn't check every connection in the unit though.

I read on these forums that one fellow with a similar problem tightened the screw below the on/off jumper and that seemed to do the trick.
I'm going to try that and will report back. But was curious on advice to a more scientific approach to figuring out what is going on?

Thanks,
Jason

Thanks for replying!
I must not have been clear though.
That is the problem.
Soft key doesn’t turn on inverter.

What inverter model do you have on your FP1?

Where the mate has the option to turn the inverter on, off, or search, the inverter is off, and the mate buttons can't change that. Nothing happens when pressing on or search.


Depending on model you have, What input do you have selected in the Mate3? Generator, Grid or what? If Grid, it take a 5 minuet wait before it will quality sync to grid...if generator can be near instantly connected due to no need to quality sync, depending again on what inverter model.

Solved it. Totally random thing.

There was a misaligned pin in the cat5 port on the inverter, I found it just by chance when checking all the wiring connections more thoroughly.

I went to fix it and when touching the pin with a screwdriver, I think first pin on the left, the inverter lit up.

So after straightening that out, I plugged the cable back in and everything is now functioning as it should.

Learned something, for sure.

Thanks
