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

What a new scc worth or is it cheaper to get stand alone charger then to fix the scc in the inverter My guess is that a replacement SCC would be well under $200, but availability of the old style SCC for PIP-4048s is unknown. It could also take some time to get one from MPPSolar, if they can and wi...

Re: PIP5048MG: 3Phase Configuration: Fault 08 and anomalies.

The 72.90 is the 5048MG cpu version. ? You said "U1 is 71.70"... so then what is displayed alongside 72.90? To me, the "CPU version" is the U1 value. Not quite - we us batteries at night - most times. However there has been a lot of rain the past two days... Ah. Setting 1 is SOL only the last few d...

Re: PIP inverter repairs and hardware modifications

Hi coloumb this inverter( inverex vm 3.2) look like Vp 3kva( i think PIP HSE 3024) , I think it's closest to an Axpert VM3000-24 (PIP-3024MSE), but with higher rated (over rated?) inverter power and MPPT output current. All the Inverex models have custom metalwork; this one also has the more modern...

Re: PIP5048MG: 3Phase Configuration: Fault 08 and anomalies.

I have heritage 3 x 4.6kW PV arrays - one for each 5048MG inverter. Voltages are above the minimum of 120V required by the 5048MG. That's slightly over the maxum PV array size specification of 4500 W. I don't think that this is related to your problem. The CPU version is 00072.90 U1 is 71.70 ? Is t...

Re: PIP inverter repairs and hardware modifications

I see two terms inverter soft start fail and bus soft start fail. As Paul has said, the bus is the ~400 V "power supply" that the inverter uses to chop into 50 Hz 230 VAC. There are two large capacitors maintaining this voltage at a relatively steady value; these have to be slowly charged at power-...

What is the PV voltage when this is happening?

Also what is the battery voltage doing? Perhaps the battery is full, or has gone high internal resistance?
