Re: PIP inverter repairs and hardware modifications

Finally! It's all working again, the zeners had failed so replaced all 6 in that area (massive pain to order got lost in post twice!)

This is all thanks to you Coulomb.

Please send over you PayPal address as i'de really like to buy you a beer but flying to Australia isn't feasible at the moment 😂

Re: PIP inverter repairs and hardware modifications

Every component in this photo has now been replaced, tested and checks out ok.

Is there more to the pwm circuit that I'm not seeing apart from the signal to the optocouplers?

I really appreciate your help columb, if you want to PM me a PayPal address I'll be happy to send over some beer tokens

Re: PIP inverter repairs and hardware modifications

I wondered for a while whether you might have a really old PF0.8 model (4 kW/5 kVA) with firmware that perhaps used fault code 07 for low inverter voltage as well as high inverter voltage. But a check of PF0.8 firmware 52.30 indicates that a low inverter voltage would be reported as fault code 58. ...

Re: PIP inverter repairs and hardware modifications

I'm only getting 20VAC when it throws the 06 error so it's definitely going to be something to do with the voltage detection circuit. But what I'm struggling to work out, all resistors up to and on the daughter board following ntye traces are ok 😣 I've completely ran out of ideas here

Re: PIP inverter repairs and hardware modifications

Well the issues persist, it's not blowing fuses anymore and at least it now turns on but I have error 06 as soon as it goes to start. I believe this is voltage to high on output but as my meter is auto ranging I have no way to prove this until my new meter arrives 🤦‍♂️ Any suggestions? I have ruled ...

Thank you very much Coulomb means I can get the parts ordered now!

Re: PIP inverter repairs and hardware modifications

Does anyone know what part number D4 D7 D8 D44 and D45 are? They're all the same and are marked L437 but online searches aren't coming up with anything also nothing of use in the service manual

Cheers

Re: PIP inverter repairs and hardware modifications

Also check all the gate drive circuitry. Often resistors and diodes, sometimes transistors, blow up in the gate drivers. There is nothing quite as disheartening as replacing 16 MOSFETs and finding that they blow immediately because the gate drivers were also faulty. Thank you for the response, are ...

Re: PIP inverter repairs and hardware modifications

Came home to all my power off this evening and found I had a dead short in one of my inverters :( Taking it apart I found one igbt and one MOSFET in pieces 😬 I'm probably going to replace all 16 MOSFETs and the 4 igbts. Would anything else be recommended to change? Could it have been something else ...

Re: PIP-4048MS and PIP-5048MS inverters

Hello all it's been a little while since I posted last hope you've all been well. I'm just curious if any of you have used the ICC APM software to switch on a control relay wired into the inverter switch (at the bottom) that switches on/off the slave inverters. And will switch more back on based on ...

Have you made sure watch power is definitely closed and the com port is open.

Re: PIP-4048MS and PIP-5048MS inverters

Good work on that clone post coulomb. I have 8 X 16mm (2 for positive and 2 for negative on each inverter and only 1.5 meters long) The voltage is fine until I boil the kettle (around 50a) and I get around 4/5v drop across the pack. Probably says more about the batteries. They were sold as deep cycl...

Re: PIP-4048MS and PIP-5048MS inverters

Tried forcing closed watch power in task manager so the com port is definitely not in use. I don't think that actually guarantees that the COM port isn't in use, since the forced closing may well bypass the cleanup code that closes the port. However, it sounds like you've been quite thorough in all...
