Wanted to check in with other forum members if their green On/Off button has an orange thing on the switch on the inside of the unit.

 

 

Finally getting around to setting up my Sunsynk (+-2 years after buying it!)., and its not showing power at the MPPT display.
I have voltage at the inputs, so I know panels are feeding in power. 

DC on + pressing the green button shows no power at the display.  If I check the switch with a multimeter, no difference if its pressed or unpressed - stays open (electrically).

Is that orange thing supposed to be there?

That looks like the latch for if you want to remove the contact module from the push button module it might not be clipped in properly that’s why you don’t get continuity.

Yup, that seems to have been the issue.

Moved it right, the button comes off, checked that, worked ok on the meter.

Put it back, moved the orange thing all the way to the left, after pushing in, now the button is making contact and making switch sounds.

So much for them checking things at the factory!

 

I can now see voltage on the secondary display, so some progress.  I guess next week time to move batteries upstairs and do a spot of rewiring!
