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

Hey coulomb and weber, thanks for the new kettle komp beta. I hope to try it tomorrow On another note adjusting the voltage reading on the 5048, mine is about 0.4 v. Higher than my multimeter. I dont undrstand what I need to calculate to arrive at the check sums? Further elucidation would be appreci...

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

Regarding charging, I am not getting the charging I expected. I have 4.5kw of panels 3s3p per pair or strings (for total of 18 x 60 cell) but seldom see over 2.5kw going into the battery (have seen 53A charging for an hour two). 02 is set to 80A, and util charging is set to 10A Hi guys thanks for y...

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

Weber, I swapped the inverters over. The original factor firmware, instantly produced more than 10 amps extra charge (43A vs 33 A) than the 72.20c in the other inverter. Have seen peak currenr around 76A from the factory version. Yet never seen over 53 A from 72.20c Go figure. More to think about Ch...

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

Weber thanks for the info and answers.

Ok well rather than reflash I have a new 5048ms waiting to be setup. So i will hook it up to the battery and panels tomorrow and check the charge current. Big issue will be waiting for sun.

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

Hi Robert. Thanks for letting us know that the LFP version of 72.20c is working for you. Regarding absorb time. I think that with LFP cells it is best to use the "Aut" setting. This will go to float when the battery voltage is within 0.5 V of the absorb setting and the charge current (in ...

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

To answer that, I need to know: Are you using 16S or 15S LFP? What make and model are your panels? I already know your approximate location and therefore your temperature regime. Weber, my batteries are 15S. The panels are REC 250 watt. I would have to get out of bed to find the model number...... ...

My 60 cell panel have open circuit voltage of 37. 2S is the current configuration open circuit is 74 V, but under load this is 55 to 62 volt. 5048 MPPT range is 60 to 115V, with max PV of 145V.

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

Hey weber , glad it all worked out. I installed the new lfp patch this morning on single inverter. The second inverter is still in its box. All seems to be working, if only I had some sun.

Love Aussieveiw. Thanks

Hello weber and coulomb, thanks for your efforts on the new Beta Version of Patched Firmware 72.20b for PF1 models with the 64V option.

Good fast work. I will try it today.

Did you get the parallel boards from Tom? If not mine have arrived.

Re: PIP-5048MS inverter

Hi Robert. The low battery warning thresholds depend on the Low Cutoff Voltage (setting 29). In the standard firmware, a low battery warning is given after the battery voltage falls below cutoff+2 V and stops after the battery voltage goes above cutoff+4 V. When we modify the firmware for LFP batte...

Re: PIP-5048MS inverter

Hi all, what setting controls the 04 low battery warning. My 5048ms is triggering at 49.5 v , which is not low for my 15s lfp batteries.

Re: PIP-4048MS inverter

My 5048 pwm has variable speed fans. It never gets hot. The exit air is barely warm with 2 kw ouput plus 2 or 3 kw solar.
But having said all that, the SCC has died and I am currenly undergoing the waranty claim process.

Weber Panels are 60 cell, connected 2s3p each string, ie 2s6p total. (Edit for 3kw total) Open circiut at the breakers is 64 atm. This PWM SCC.

Re: PIP-4048MS inverter

Weber, on utility, not charging yet, Battery at 51.0

Interestingly the pv feed after the breaker is =batery voltage with both PV stings isolated from the 5048.
Seems like you were correct re the SCC short.

Re: PIP-4048MS inverter

Weber, the battery voltage at 50.5 PV at 51.5, charging at 35 amps atm.

Yes U1 is 34 10, remember this is 5048 so thats why weird number.

No utility atm but will try soon

Re: PIP-4048MS inverter

Weber and Coulomb, thank for the detailed replies. Looking forward to sending the lead to Pb heaven. At close to a ton, it should give me money to buy more toys. I ordered a BMS from the same WA place as the Calb180s. hopefully it will do the job, but I do wish i had asked you guys first. cheers Rob...
