marcelino Oleana Posted May 14, 2021 Share Posted May 14, 2021 Dear Sean, I have a problem with my inverter. I’ve a U Power (Power Jack) 48v, 15000w split phase inverter. (120/230V output) I’ve taken it from the wall to repair the transformer bolt Isollator. When it was repaired, I installed it again. After connecting the battery and output wires I started the inverter in po save mode on. During the starting of the inverter I remember that I was running the inverter in power save mode off and I’ve switched from power mode on to off mode and directly to Power save off. After doing that, the red lamp (Alarm), the green lamp (BTY) and the green lamp (INV) on the inverter begin to flickering and the inverter did not start any more. The book is not explaining how to reset the alarm. I took the battery wires off for 35 or 45 minutes so thinking that It will reset but after connecting the battery cables back the same thing was happening again. I think that maybe something is burned inside the inverter. Can you find out of my information what could happen? Do you know where I can get parts? If parts needed to replace? Thanks for your help.

Sid Genetry Solar Posted May 14, 2021 Share Posted May 14, 2021 Can you provide a short video showing what happens when you turn the inverter on? A few internal photos would also help start to pinpoint what's wrong. Quote Link to comment Share on other sites More sharing options...

Sid Genetry Solar Posted May 15, 2021 Share Posted May 15, 2021 Well, for once the mental picture I had matches what is actually happening 😉. Right off the top of my head, I'd suspect an internal wiring problem. Not sure exactly what it is at the moment; some internal photos should help figure out what's going wrong. Looks like the power supply is getting overloaded. Could possibly be a failed cooling fan, particularly if it's plugged into the control board.

ask first Posted May 15, 2021 Share Posted May 15, 2021 Do you guys upgrade these power jack inverters bought of eBay? If so how much? Quote Link to comment Share on other sites More sharing options...

The more we try to do with the inverters, the less of the PJ originals can be used--making it more or less pretty much a waste of time. Here after this next shipment of inverters, we'll have a 100% custom design...none of which is backwards-compatible with a PJ inverter. (Except for the transformer--which is the weakest part of the whole inverter.) Quote Link to comment Share on other sites More sharing options...

Hi Sean, I will open the inverter on Monday and make some pics for you. I'll check also the fan. There is an an adapter or something else plugged i by the sock of the fan before it go to the control board. Quote Link to comment Share on other sites More sharing options...

dickson Posted May 16, 2021 Share Posted May 16, 2021 Do you guys upgrade these power jack inverters bought of eBay? If so how much? I think a new GS mainboard with bead on cables and diodes on mosboard is require to make the GS upgrade to work . Some PJ transformer will not work with GS upgrade . Powerjack in china made a new replacement 10.3 control board that will upgade older PJ inverter with new mosboards and mosfets and frequency driver . You need to send PHOTOS of your older PJ inverter to see if mainboard need to be change also . No instructions for installation is sent with the replacment parts . It is very easy to mis wire the 10.3 board because there a many different 10.3 board for different PJ design . Quote Link to comment Share on other sites More sharing options...

Half band-aid; works on 6kw and less. These fixes aren't sufficient for any larger wattage inverters (GS 12kw, etc.)--which is why we're fully ditching every last bit of the PJ design, as it can't be used fully and successfully. 4 hours ago, dickson said: Some PJ transformer will not work with GS upgrade While they're all rather poorly specced, all of them can be used...just with varying degrees of success. In my opinion though, it's kinda a waste of money to replace everything else, and still have the same ol' major bottleneck. 4 hours ago, dickson said: Powerjack in china made a new replacement 10.3 control board that will upgade older PJ inverter with new mosboards and mosfets and frequency driver . Frankly....there have been no significant changes to the PJ design since version 4. Just repackaging the same design different ways. Latest FETs are really weak though (60A vs 180A); definitely not in favor of that change. 1 Quote Link to comment Share on other sites More sharing options...

I think the PJ 20kw inverter is actually 7 kw continuously on inductive load . The 25 kw PJ is 8 kw continuously on inductive load and the PJ 30kw is 9 kw actually . This is base on running my 8kw PJ that is now 2 years on 220vac at less than 3000 watts and my 15kw PJ at less than 5000 watts with no problem. 1 Quote Link to comment Share on other sites More sharing options...
ituscol Posted February 18, 2022 Share Posted February 18, 2022 good afternoon, bought a UPower (power Jack ?) 48v 15kw dual phase, with charger inverter, I live in Colombia and the trip might have taken a toll on it and I made the mistake of not opening to check that all was in place before connecting to my power bank and turn on, when I turned it on heard and saw sparks so I turned it off and opened it and surely the control board was lose and made a short. Put everything in place made a bridge where the board was burned, checked mosfets the ac side were all burned, ordered and replaced same exact boards, also ordered a control board but sent me upgraded not exactly the same board but power jack said that it will work on my inverter also inspecting the board under the capacitors there was also a landing burned up, put a jumper, so everything in place the inverter turns on en seems ok, connect a small soldering iron and all ok, but if I add my 1800 watt heat blower it an alarm goes on telling me that load is 100% and in ten seconds it would turn off and it does, I also notice that the fan doesn't turn on even if I apply heat to the sensor on the transformer until the alarm goes on so the sensor work but the fan doesn't turn on. Please help me thanks. Quote Link to comment Share on other sites More sharing options...

Is the fan connected to the control board, or is it soldered to a different heat sensor? Most of the previous PJ inverters had a click switch glued to the transformer that controls the fan, which is completely separate from the temperature sensor that causes the inverter shutdown. 2 minutes ago, ituscol said: connect a small soldering iron and all ok, but if I add my 1800 watt heat blower it an alarm goes on telling me that load is 100% and in ten seconds it would turn off and it does, Did you copy the "DIP switch" settings from the old control board to the new control board? If these are not set, it will overload and shut down at very low loads. (switch circled in red here) Quote Link to comment Share on other sites More sharing options...
ituscol Posted February 18, 2022 Share Posted February 18, 2022 power Jack assured me that it was all set for 48volts and 15kw, but yes I checked and they are set the same, and don't know where to check for the fan circuit. the fan is connected to a sensor on the transformer and the mosfets on the ac side Quote Link to comment Share on other sites More sharing options...
ituscol Posted February 18, 2022 Share Posted February 18, 2022 I heated up the sensor glued on the transformer until the alarm notice of overheating of transformer turned on and the inverter turned off. but fan didn't turn on and there is no connection from fan to the fan plug on the control board.

ituscol Posted February 18, 2022 Share Posted February 18, 2022 its a four cable high speed fan can I override the sensors and have it stay on all the time? Quote Link to comment Share on other sites More sharing options...
ituscol Posted February 18, 2022 Share Posted February 18, 2022 ok the overload problem is solved with the new board but I would like to have my fan always on can you show me how to connect it to a manual switch? Quote Link to comment Share on other sites More sharing options...

Sure can. PJ used to have a switch for doing just that. 42 minutes ago, ituscol said: power Jack assured me that it was all set for 48volts and 15kw, but yes I checked and they are set the same, and don't know where to check for the fan circuit. the fan is connected to a sensor on the transformer and the mosfets on the ac side Have heard a number of customers noting that the new "v11.0" board overloads considerably sooner than the previous ones...

ituscol Posted February 18, 2022 Share Posted February 18, 2022 here is a foto of the inverter thank you Quote Link to comment Share on other sites More sharing options...
dickson Posted February 18, 2022 Share Posted February 18, 2022 photo of the inverter thank you I see from the picture it is a rev 11.1 control board and is working . The LF driver has no Led turn on which is the new design . The red light alarm is working to shut down the inverter . The transformer look like my 8kw PJ invertetr . My 8kw PJ can do 2000 watts with the rev 11.1 control board . Your 1800 watt heater and the solder iron will be more than 2000 watt and the red light alarm wiil shut down the inverter . You can take the red and black wire from the fan and direct wire to the pos and neg terminal of thje battery cable connection and not use the sensor yellow wire . Try a 1000 watt hair dryer and it should work ok . Quote Link to comment Share on other sites More sharing options...

ituscol Posted February 18, 2022 Share Posted February 18, 2022 my system consists of 8 solar panels 380watts 38volts 9.2amps a piece wired in couples to give me 76volts for a 48volt system, connected to a midnight solar classic 150 charging 3 banks of batteries in mixed fashion lead agm 8 200ah northstar blue groups of 4 in series to give me 48v, another bank of 2, 48v lifePO 100ah each in parallel, and another bank with the same lifePO caracteristics. the litio banks are connected to 4 solar panels monocristaline, 400w, 40v 9.8amps in series and parallel to give me 80v feeding a Makeskyblue 60amp wifi controler, and the other bank with the same panels connected to a powermr 60amp controler, and all this connected to a 15kw, 48v split phase power jack inverter, it handles anything I throw at it including motors and electric soldering, household appliances etc, and run it day and night without any need of the public electricity I bought this other inverter because my old one is just great and want to connect it in parallel to get even more power out of the system.

ituscol Posted February 19, 2022 Share Posted February 19, 2022 before I had 16 100ah agm bank and decided to sell half the bank and add these lithium lifePO batteries and gave me 100% improvement lasting all night with minimun discharge due to lithium maintaining its charge longer than the lead agm, but the lead agm handle heavy loads and they work fine together up to now.
