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

I'm using a python module and it works fine for all other commands I am sending. Not sure it handles NAKs too well, (seems to crash) I'll look into that but when I do any command that gets ACKed I get the ACK printed to the screen. I'm assuming that cos I don't see an ACK that I got a NAK. I've trie...

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

Is it possible to change the AC voltage from the default of 230v to 240v. Some posts on here seem to suggest it is by using POPV2400 command but when I tried this it did nothing?

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

The only unknown here is what did they change between 72.20 and 72.30? OK, I think I'll take the hit and do it. If they have added anything (unless it gives the dynamic charge control that your firmware offers) then it's nothing that I'll miss since I mainly want to tell the unit to charge and at w...

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

Once you have updated the firmware in your PIP, is it possible to revert back to the original (does the update create a backup of your existing firmware first) or is this a one way trip? Will the modified firmware remove any features from the PIP? What I'm trying to say is that my PIP is the 64V ver...

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

That doesn't completely answer the question. You might be making a home-make LFP battery. What is the nominal voltage of your cells? If around 3.2 V, then it's LFP. If 3.6 V or more, it's not LFP. It's definitely Lithium Ion (not Lithium Iron Phosphate) so 3.7v per cell. you need the LC flavour of ...

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

Please check that your present firmware is 72.20 or thereabouts. If so, you can update to 72.20e patched firmware. My current firmware is 72.30, that should be ok? Is your battery LFP (LiFePO₄), or other Lithium Ion? It's home made Lithium Ion. From what I was reading it looks the the non LiFePO4 f...

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

Hi, newly joined member here. This seems to be the place to find information when it comes to MPP Solar inverters. So I've got my brand new 5048MS(64) sitting in front of me. It's a nice bit of kit. So far I've wired it up to one of my L-Ion batteries and the mains and had a little play. I've connec...
