Re: PIP inverter repairs and hardware modifications

The inverter ships with the same RJ45 to DB9 connector, as well as a USB A-B cable. So what's the USB port for? Can you run the WatchPower software through USB without a USB dongle? Does it have to be a recent version of WatchPower if so? I don't know, sorry. The guy I was speaking to wasn't able t...

It's the same RJ45 connector for serial, and a USB type B connector.

Re: PIP inverter repairs and hardware modifications

Someone on mybroadband.co.za was nice enough to take a photo of the back of his 2015 comms board. http://forums.aeva.asn.au/uploads/3980/Comms_board_2015_b2.jpg The IC is labelled as a SC510070JDME, but after some poking around it seems to be a MC68HC908JB8. I thought it'd be a generic usb-serial ch...

Re: PIP inverter repairs and hardware modifications

That's great, thanks very much. The inputs to the board look the same, and it still looks like it drives RS232: the RJ45 connector, optoisolators for the serial lines and two capacitors for the dual supply which wouldn't be needed if it were USB only. The 6MHz crystal is probably for a USB-serial ch...

Re: PIP inverter repairs and hardware modifications

after looking at your photos again Thanks for the photos, they're very helpful. That black box is a relay ( see here ) and it looks to me like they're routing it out to the RJ45 on pins 3,4,5 although it's difficult to see clearly with all the silkscreen. http://forums.aeva.asn.au/uploads/3980/2013...

Re: PIP inverter repairs and hardware modifications

Does anyone know the pinout of the RJ45 communication port by any chance? Is there any power available on there? I see there's a remote display panel available that doesn't need external power as long as the inverter has dry contacts. My hunch is that there's 12V on there but want to see if there's ...

PIP-4048MS inverter

To enable sending of characters with the high bit set... Crikey! That's no fun. I wrote a little calculator app (Windows only): CrcGen It spits out the command+crc as hex bytes for pasting into something like RealTerm. http://forums.aeva.asn.au/uploads/3980/crcgen.png It needs .net 4.5 installed if...

PIP-4048MS inverter

Thanks for sharing. AFAIK the 4048 has a flat fee of roughly 50W. All inverters have their sweet spot though, it'd be interesting to see it over a range of loads.

Is the heater you used resistive only (does it have a fan motor?) I'd be interested to see the VA as well.

PIP-4048MS inverter

Hi, I just registered to say thanks to Weber and Coulomb for reverse engineering the CRC. For anyone wanting to make devices that communicate with the inverter, I've put together a simple emulator tool which responds in the same way as the inverter but lets you test out the fault flags without disru...
