PIP-4048MS inverter

2 x 4 works good so 3 x 3 should be ok. It seems like it is better to have the mppt scc fed with higher voltage. The mppt range for 2424msx is 30 - 115. I have tried 1 x 7 and 2 x 8. With 1 x 7, a lot of the time, the PV voltage is around 30 which is too low. 2 x 4 gives PV around 60 when loaded and...

PIP-4048MS inverter

Here that model is pip2424msx. 60A mppt scc. Model 2448ms is good too. As long as you don't need more than 2.4kw out. They use less idle power. 3000w scc. But no parallel function. What configuration did you use to connect the panels. I use 4 x 2 on the 2424msx. 36v 280w panels.

You have the latest model. They have changed from rj45 and nine pin cable to usb because most laptops do not have the nine pin serial port

PIP-4048MS inverter

Yes. Thats the lastest version. Be good to know what the difference is between the 2. I will load 72.40 and see if I can notice any changes. One difference between 52 25 and 52 30 is the fan speed. What about U2, the scc firmware. What version have you got for that. You would have to expect that 72 ...

PIP-4048MS inverter

With 52 30 firmware, the fans run much slower on light loads. 1200w should make the fans run. You need to look at them to see them spinning. I turn the fans upside down and apply lanolin grease to their soldered terminals. I notice on late model pips that the fan soldered terminals are now coated so...

PIP-4048MS inverter

Use big short battery cables. I am installing a 3248ms today. 12 x 280w 36v 4 x 3 and 8 x 250Ah AGM. No utility or generator. 6 panels facing east and 6 facing west. This setup does not seem to upset the MPPT. You might want to have your panels facing more to the east because the generator starts in...

PIP-4048MS inverter

Chris, It's got to be a typing error but even so you have nothing to worry about. You will never get more than 60A battery charging out of the solar panels and you will never get more than 60A battery charging from the generator. The generator starts at 5pm so there wont be much solar charging at th...

PIP-4048MS inverter

I think the reason that the fans run fast all the time in firmware 52 25 is that mppsolar were trying to cure the problem of failures of the mosfets on hs1, thinking, like me taht it was an overheating problem. But running the fans fast all the time does not fix the problem. Higher rated mosfets doe...

The more load that you place on the inverter, then the faster the fans run. Just tried 2.8kw and 3.6kw.

PIP-4048MS inverter

I would expect that they are the same fans. If someone has one, can the take the bottom cover off and see what fans they are. I had a 4048 running 52 25 and changed it to 52 30 and now the fans run a lot slower. 2kw load and they were still slow.

PIP-4048MS inverter

Chris, I dont think you need to worry too much about putting too much current into your battery bank. They will take a lot of current when they are in a low state of charge and if you try to push too much current into a small battery bank, the voltage will rise to the equalise or float setting and t...

Chris,
I think all you need to do is enter appropriate values from the lcd screen. Just try scrolling through 02 and if 30 shows up, enter that. We use firmware 52 30

Chris, Have you actually scrolled through the options of prog 02. I just read the old and new manual for prog 02. The old model clearly states the 6 options 10A to 60A. You have to read the new manual closely from page 14 to see that there are now 12 options for prog 02 4k/5k 10A to 120A. You should...

Re: PIP inverter repairs and hardware modifications

ALL of the mosfet are 11-320110-00G (MOSFET IR/IRFB3307ZPBF 120A 75V N BULK TO-220).* *: In the new version, they will be 11-320138-00G (MOSFET TI/CSD19505KCS 201A 80V N BULK TO-220) or 11-320117-00G (MOSFET IR/IRFB3077 210A 75V N BULK TO-220) No...

Set 19 to FEP, 20 to LON and then have both screens display load in watts. Each inverter should hunt a bit. One will go up while the other goes down and vice versa. Then read your battery current with your clamp.

Just did a better charging test starting at 51v. Battery charge current gradually increased to the 30A current limit. Then voltage gradually increased to the value in 26, 57v. Then current gradually decreased to 10A and then switched to float. Not sure if the switch to float is time dependent. As it...
