Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)

@ Prajna or @coulomb if you can supply me with commands for my PIP would be just perfect! Any help would be much appreciated! Hi Andre, sorry I didn't see this till now. I'm still doing my best to figure out the protocol. It seems there are a number of different versions that all report themselves ...

Re: PIP-5048GE, PIP-5048GK and PIP-5048MG inverters (with unsafe SCC)

I have just seen that the 8 chars do some timeouts, too. So it gets worse the longer the command is. Strange... I guess I will have to try to fix it with the creator of this software. I looked into it, but do only get half of it. :( Hmm... are you using usb to talk to the inverter? It seems that us...

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

Excellent. Thanks Coulomb. All clear now. QFLAG gave me a few problems too but I figured it out eventually by looking at the actual response from the system and rereading the protocol. Boy do they go strange and inconsistent ways of doing things!

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

Thanks for spotting that, Coulomb. I'm still confused about the status field though. You say it is in the format '999'. To me that suggests we can have 3 values (or flags) expressed as ascii 0s or 1s. So you are working from the raw word in the firmware (16 bits?) but how does that get packed into a...

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

This is the variable bPVMode. It values are 0 Power on mode. QMOD reports P. 2 Standby mode. QMOD reports S. 3 Battery mode. QMOD reports B. 4 Line mode (BYPASS displayed). QMOD reports L or S if main switch is off. 5 Bypass mode (like line mode, but the bus voltage is too high). QMOD reports L. 6 ...

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

Hi Paul, sure I have a number of different versions of the protocol file. It's a bit like standards: there are so many to choose from and none are standard :) It seems much of the protocol is undocumented and the different versions are incompatible. For instance the MPPT-3000 Standard RS232 communic...

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

Well I have to say, it's taken me several days to read all the posts on this thread but, man, it is packed with fabulous information. Hats off to Coulomb, Weber and the rest of you guys! My first post on the forum. I came here looking for information on communicating with these and similar Voltronic...
