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

Additional info - SCC board measures wrong (higher) PV voltage. With disconnected PV array there is on PV input 53V (same as on battery) but SCC reads 55V (shown on LCD). In QPIGS SCC reports battery voltage 52.95V, so at least measurement of battery voltage is OK, and in measuremnt of PV is some er...

Re: PIP-4048MS inverter

My problem is that at night , the scc stays on , because somehow i get voltage on the scc coils ( driver 1 , driver 2 ) And i need a setting that will cut scc at higher voltage ( i have like 2volts + the battery voltage all the time on the pv input ,when the scc relay is connected ).If i change cha...

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

Some data from my PIP - I use 32x 100Ah LifePo4 configured 16S2P to get 48V nominal. PIP4048 settings [26] = 55,0V, [27]=54,2V and [2] =30A Few samples (Ubat, Ibat) , where is shown step no discharge (or low) followed by high discharge current. 52,90 -4 51.90 -44 I can put more data in file attachme...

Re: PIP-4048MS inverter

Hello coulomb and weber, did you plan in next firmware add/modify PIP commands to dynamically switch to bypass mode (for LiFe batteries)? Now we have possibility to dynamically limit charging current (good for top balancing), but it would by also great to have possibility to force PIP in bypass mode...

Re: PIP-4048MS inverter

Hello, on LCD is shown battery current 1A, but real current measured on battery wire is 0A (oscilating +- 20 mA). PIP is in bypas mode (L). QPIGS response is 235.1 49.9 235.1 49.9 0564 0525 013 412 51.00 001 028 0038 0001 060.4 50.99 00000 01110110 00 00 00086 010 Your QPIGS response shows 86 watts...

Re: PIP-4048MS inverter

Hi @DanoP. Thanks for reporting this. Can you please tell us what battery current is shown on the LCD when you get the false reading from QPIGS? Do you get the same false reading on the LCD? Hello, on LCD is shown battery current 1A, but real current measured on battery wire is 0A (oscilating +- 20...

Re: PIP-4048MS inverter

Hallo, I have some strange battery current (charge, discharge) reported from PIP4048 (QPIGS data) when in PIP is line mode (bypass) and PV charging is starting (PV power about 60 W in early morning). PIP reports charge current 1A (difference between battery charge current and battery discharge curre...
