Re: PIP-4048MS inverter

Hi, Robert. We used to be able to read firmware from the DSP (inverter's processor on the daughter board) using slightly special equipment, as posted in I believe the "if your inverter is bricked" post, but as of the last year or two they use a password to protect against this. So I don't think it's...

Re: PIP-4048MS inverter

One of our clients' PIPs was updating firmware very slowly. We were able to swap its comms board with one from another PIP to get the firmware updated, but the original comms board still needs fixing. To help find out what was going on, we did a partial trace of the comm board. We were not intereste...

Re: PIP-4048MS inverter

Rik, the dual- and triple-MPPT models do seem to work somewhat differently to the single-MPPT models. I never see that weird behaviour [ edit: with my single-MPPT machine] with the PV voltage readings; it always reads zero at night, for example. In fact, at night, the single MPPT SCCs (Solar Charge ...

Re: PIP-4048MS inverter

3 x 4kW inverters linked in 3 phase would produce how many kW 3 phase? Energy is always conserved. Power is just energy per time, so power is also always conserved. So 3 4 kW inverters produces 12 kW. That can be as 3 single phase loads at 230V and 17.4 A each, or three phase to phase loads of 400 ...

Welcome to the forum. I'm interested in using Raspberry on USB with ICC software and serial connection with a PC for Watch Power. is there any solution to this?

Re: NRMA funding 40 DCFCs around NSW

Another question - are DC fast chargers compatible with J1772 or do they have a different connector? When we finished my conversion there was no J1772 and we used a normal 3 pin plug. In Queensland, all the DC fast chargers are accompanied by AC chargers as well; these will be J1772 compatible. [ E...

It works but I have to reset the Ampfibian severa...

Will this work with the hybrid-v series?
No. These operate very differently, so they can't use the same firmware.

If you are asking could something similar be done with the V series, I suppose that's possible, but Weber and I won''t be doing it.
