PIP-4048MS inverter

The slave inverter does not shut down at low load. Also overload bypass does not work. I have also had a problem with generator connection. If the output from the pips is separated, 28 set to 51G, the generator connection works. If outputs are joined and 28 set to PAL, then generator will not connec...

PIP-4048MS inverter

I have more than 10 sites running parallel pips 3248ms and 4048ms and 1 site with 3 4048 in parallel. My one at home has 2 4048ms in single phase parallel. Mine is connected to the mains also.

PIP-4048MS inverter

I used to use strings of 2 x36v 280w panels. Now I have changed to 3 in series. The heatsinks run hotter but I get more power out. You would think that the lose due to heat would mean less power out. A HS model would work better with 2 panels in series. 15 panels 3 x 5 is the most I ever connect. I ...

PIP-4048MS inverter

I am having a problem connecting generators to 4048's running 52.30 and 72.40. Works with mains connection but not with generator. I thing 52.25 works but then the fans will run too fast. I will try 52.25 again to confirm. Generators always work with 812, 1624, 2424 and 2448 but not 3248 and 4048 bu...

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.

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...
