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

Thank you guys for providing temperature values that I can compare to and good advice! A typical set of temperatures for my inverter is 36/34/41/44 °C for SCC/AC/Battery/Transformer temperatures respectively. Mind you, that's at 23 °C ... I reported those values at 23 °C ambient. Now I'm starting to...

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

Checking in to report 3 and a half month of running version 73.00c without issues on a phased setup of 3x PIP4048MS with LiFePo4: https://fastdigitech.ro/userimages/softwarever.jpg I love the fact that I can select independently what to display. That allowed me to check on the temperature of the inv...

Re: PIP-4048MS inverter

.... The active is switched between the inverter and the grid, and the neutral to the inverter disconnects when in there is no inverter output, but the load always connects to grid neutral. .... If I read the above correctly in your setup the grid neutral will be connected to the inverters' output ...

Re: PIP-4048MS inverter

Could it be the panels weren't at max power point until the inverter took some of the load? Likely array output was higher than what the batteries could take? Thanks, that could have been an explanation as I haven't provided all the data: the power generated at the moment was well below the maximum...

Re: PIP-4048MS inverter

It's the second time I see my inverters reporting a brief surge in PV production the exact moment of the switch from grid to solar. Would this be a freak coincidence, an artifact of the monitoring software (ICC) or just normal physics (that i would like to understand)? I caught the event from today ...

Re: PIP-4048MS inverter

Those are a bit high. See the PowerForum (they seem to use a lot of Pylontech batteries there), e.g. this post . I'm reading as fast and as much as I can. It looks like I should lower the floating value to a safer value There is very poor matching on voltage measuring between the 3 units: 0.4V diff...

Re: PIP-4048MS inverter

Joining in with a 3 phase setup using 3 x EFFEKTA AX-M 48V 5000VA and a couple of PYLONTECH 'US2000 plus' lifepo4 managed battery modules ( 2 x 50Ah) Many thanks for the great effort to reverse engineer and improve the firmware on these inverters! I'll read some more and I will flash the latest firm...
