Since I put the solar panels ontop of the trailer I haven't used the PD 9280 I put in a few years ago. When I parked the trailer a while ago in the RV Port I plugged in the trailer my trimetric showed the converter was not putting out many amps, then I noticed the LED on the wizard wasn't lit up and pushing the button didn't do anything either.

It's stilll plugged in, I removed the jack and plugged it in again and still can't get the converter into bulk mode.
So my question is do you think the issue is the wizard or would something be wrong with the PD9280?
Thx

What is the charge in the batteries?

What is the battery voltage?

Consider disconnecting the panels and check the PD operation next day. With the wizard light out I suspect an open power circuit to the battery or 12v system. Possibly the wizard communication cable was disconnected.

Batteries were at 66%.
It was charging the batteries but not in bulk mode, and like I said I disconnected and reconnected the wizard phone jack.

The LED of the Wizard should normally be on when the PD is on.

Technically the Wizard is built in to the PD unit. The thing with the LED and button is an optional remote pennant. If the LED isn’t lit and the unit doesn’t seem to produce any current something is probably wrong with the PD itself. It could be as simple as a blown fuse.

You can also try disconnecting the pennant and see if there is any charging current in case the pennant has failed and is confusing the main unit.

Way back, the graphs the OP produced indicated the unit went into Boost by itself because the batts were low enough. The unit dropped to Float after about 3 hours.

If the CW had been used to initiate Boost, AFAIK it should have stayed at that for a full 4 hours, then drop to Float.

In this case, it would be worth running the batts down to under 50% SOC, and then connect the PD9280 to see if it still would go into Boost by itself. If it did then a new pendant would be indicated.

Thanks Barry, that's a good idea and is what I'm gonna try next.

I *DO* remember it didn't put out the max 80 amps very long but it charged a lot faster than the WFCO the trailer came with.

Barry, I took the batteries down to 44% and plugged in the trailer, got 77.5 amps on the Trimetric so it IS going into bulk mode, will order a new "Wizard" and hopefully that works.

It's funny though, since I went to solar I got outa the habit of even looking at the wizard to see what was going on until now.

You need to see the voltage at the converter's terminals (not the battery's) as 14.x to know if it is in Boost. It is possible to get high amps at 13.x at first with a low battery.

A version of Fisherguy's old graph here with "photobucket" written over it for some reason: scroll down to Salvo's post with the graph

EDIT here is Fisherguy's actual post on that
