PIP-4048MS inverter

I always turn the fans upside down and treat the soldered fan contacts with lanolin grease. There is a plug at the top of the main board marked fan3

PIP-4048MS inverter

I have installed 2 of the new type 4048ms in parallel without the big black heatsink at a site about 200klms from where I am now. The single scc is mounted on top of the main pcb heatsinks. The units have been in operation for a couple of months with 12 x 280w panels connected to each one. They do r...

PIP-4048MS inverter

No. Just split system but not inverter. Also just completed a job yesterday with 2 4048in single phase parallel running 3 of those big coke coolers with glass doors and 2 500l deep freezers and the 4048's were able to start up all of them together.

I have a 2424mdx on the way. 2 40A mppt inputs. I will get a 3 x 60A 4048 when they are available.

PIP-4048MS inverter

Just checked the 2424msx and it is now in float mode. Made a liar out of me. Did not do that the other day. Oh well. At least it is charging the way it is supposed to.

PIP-4048MS inverter

With 02 43 firmware program 26 and 27 do not appear. I just connected it to ac and it went straight to float because start voltage was above 25. Lowered start voltage to below 25, now voltage at 29.2 and current 17A. Voltage will stay at 29.2 and current will taper off but unit will not switch to fl...

PIP-4048MS inverter

Fld sets them to 29.2 and 27 but it never goes to float just stays on bulk. I will connect a 2424msx now to batteries and ac and set o5 fld and leave it overnight. I bet the battery voltage is 29.2 in the morning. This one has 02 43 firmware.

PIP-4048MS inverter

I noticed that if starting voltage is above 25 then it goes straight into float. This is ok because if you start the day at 25+ you don't need bulk charging because the batteries are fairly full. I tried fld and ac charge starting at less than 25 volt and the battery voltage climbs to 29.2 and stays...

PIP-4048MS inverter

Will be good when these solid state li batteries become readily available. For the 4048 charging, it looks like you just need a break in the charging for it to go back into bulk charging mode.

PIP-4048MS inverter

I just tried a 4048 on 240 charging and the start voltage was 50.9 and it went up to the bulk charge setting of 57v. I know with 2424 the start voltage has to be below 25 for it to go into bulk charging but I did not think it mattered with a 4048. If the charging starts at a high voltage then it wil...

Re: PIP inverter repairs and hardware modifications

Yes. You notice that when AGM's are full, they don't regulate voltage as good. But that could be said of all battery chemistries, I think. I wonder if setting the float to 52 would help. But really the scc should react quick enough to a change in solar current so that it is not the batteries that at...

Re: PIP inverter repairs and hardware modifications

Yes. Saw your videos. I don't think it is the number of panels or too much inductive load that has been causing the failures of mosfets on hs1. I have one site with a 2448ms running 15 x280w and 4 500 ltr deep freezers and no problem. It has 12 x 12v250ah AGM's. I just had another failure last week ...

PIP-4048MS inverter

Another good setup would be having a 4048ms with 04 set to sen and beside it a 2448ms. Common battery bank. 24 x 280w panels, 3 x 4 to each inverter and have separate ac out feeds. The 2448ms would feed lights, fridge and anything else that is on often and the 4048ms would feed the high power seldom...

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.
