PIP 3024GK Error 09

Post by bcg »

Hi All,

Directed here from Whirlpool. You guys seem to be the pip experts.

MPP Solar PIP 3024GK dead with error 009 at 14 months old.

Dealing with MPP solar now but they're slow to reply. Interested in your views.

No obvious damage, corrosion, blackening or smell of smoke.

Have tested the following:

Q18: 0.412
Q35: 0.412
Q23: 0.412
Q13: 0.409

QB2: 0.358
QA1: 0.358
QC1: 0.358
QD2: 0.356

Q40: 0.409
Q26: 0.412
Q25: 0.412
Q39: 0.412

Q27: 0.0
Q31: 0.0
D13: 0.0
D82: 0.001
Q17: 0.46

Q10: 0.347
Q11: 0.347
D52: +/- 0.355 -/+: 0.347
R238: 0.7 ohm

So, D52 appears a bit funky along with Q27, Q31, etc.

Anyone has a similar failure?

Thanks,
Brad

Welcome to the forum.

We're more familiar with the 5 kVA models, and with the MS models (low voltage Solar Charge Controller). But fortunately, there is a lot of commonality amongst the various models.

That's fairly early, but not unheard of. The recent hot weather will test them more and more.
Have tested the following:

Q27: 0.0
Q31: 0.0
D13: 0.0
D82: 0.001
Those are definitely dead. Although D13 is across the DC bus, and may be showing zero ohms because of Q31 shorted, and L1 has negligible resistance.
Anyone has a similar failure?
It's not quite the classic failure, where either the DC-side MOSFETs, the bus-side IGBTs or the inverter-proper IGBTs fail shorted. But it looks familiar.

Consider replacing the DC-side bypass capacitors with longer life parts, though it looks like it would not have saved this failure.

Anything unusual at the time of the failure (e.g. lightning nearby, switched off inductive load, etc)?
Nissan Leaf 2012 with new battery May 2019.
5650 W solar, 2xPIP-4048MS inverters, 16 kWh battery.
1.4 kW solar with 1.2 kW Latronics inverter and FIT.
160 W solar, 2.5 kWh 24 V battery for lights.

Thanks for the reply.

The unit is in Tassie so temperature c.f. the rest of the country wasn't a problem. We were also not home and no inductive loads beyond a fridge switching on and off that hadn't been opened in hours.

Good spike of sun. Where the batteries were probably nearly fully charged. I saw a rant on youtube about this particular failure case so I'm thinking this could be it. He had suggested that it was the caps failing that then took out the row of mosfets. The caps look visually ok.

Thanks for the feedback on the values. I haven't gone and traced things through so not quite sure on where things might show spurious values in circuit. Our friends at MPP solar sent through the service manual and they should all show more or less reasonable diode kinda voltages in circuit.

Thanks,
Brad

Hello,

I am using this exact model and the temperature goes as high as 45degree, now I am worried seeing your post. The manual indicate operating temperature to be up to 55degree. I am not yet up to 14 months of usage hence would like to hear suggestion on how to prevent this issue.

If you mean the user manual temperature specs, thats is the ambient temperature upto which it operates.

I have the PIP4048 and when I measured the heatsink temps it went as high as 55c .
As I do not like this sort of temperature on power supplies I have built I was not happy with this
so I attached two 120mm fans to the two side vents pulling air out and used a temperature control from e-bay.
I insulated the probe and put it into the fins of the heatsink
I set the control to turn them on at 42c and off at 36c this keeps them much cooler
This should make all the components last longer.

When you replace your faulty Comm board, try changing your fan to blow inwards. That will lower your temperature a bit.
