PIP-4048MS inverter

Speaking as a person that's spent my fair share of time deep in the bowels of code for embedded systems like this one I'd have to say - I'm sure everyone realises - what Coulomb and Weber have achieved by reverse engineering the firmware here is 'NO SMALL FEAT' - not by any stretch. There would be v...

Re: PIP inverter repairs and hardware modifications

Yep Solamahn I suspect it's ripple the charge controllers are trying to chase, and that's what Eric implied also. If my understanding of ripple is correct more batts = more 'capacitance' = batts filter the ripple. It still highlights a problem - better to deal with the ripple at the inverter and cha...

Re: PIP inverter repairs and hardware modifications

Sounds like you folks have made some awesome progress here - congrats to Weber and Coulomb for a job well done.. LOL Coulomb - the power switch you so describe on the front panel of the 2013 model doesn't come out of the factory that way - but I did modify mine that's with Weber at the moment so tha...
