dickson Posted August 30, 2022 Share Posted August 30, 2022 I brought a aliexpress EG8010 inverter board complete with FETs and heat sink and wires and diagram to connect to a 30vac primary toroid transformer . I remove 3 turns of the ASL9.0 to make it a 32vac primary . It works with some adjustment to ac output voltage . The maximum load for this experimant is less than 100 watts . Something you can do with a junk PJ inverter to play with . I will connect the ASL9.0 back to the original case after this experiment .

Sid Genetry Solar Posted August 31, 2022 Share Posted August 31, 2022 Funny how TINY the main DC filter caps are in there....probably good for about 1A of ripple current max each! Quote Link to comment Share on other sites More sharing options...
dickson Posted August 31, 2022 Author Share Posted August 31, 2022 Funny how TINY the main DC filter caps are in there Yes those caps are useless . I was surprise that it works with a PJ ASL9.0 and use it for light bulb only . The ac voltage is unregulated for inductice load and sag so is only use for resistive load . There is almost no youtube on a working EG8010 inverter board . All the youtube say the FETs blow up for unknown reason so I keep the load under 100 watts . It is fun to do experiment with PJ inverters and the ac voltage stay 129 constant with 55 vdc input . Quote Link to comment Share on other sites More sharing options...
Waterman Posted November 12, 2022 Share Posted November 12, 2022 Funny that the 9kW unit is rated for 96 Volts. The EG 8010 boards range fro 12V at 3kW to 96V at 9kW with the ones in between rated at 24, 36, 48, 60, and 72 Volts. Quote Link to comment Share on other sites More sharing options...

To be useful for load up to 9kw the capacitors need to be bigger and the RUI FETs will probably works to stop the Miller capacitance . The LF driver IC need to be better like on the GS inverter . The protection circuit on this Aliexpress inverter that suppose to protect the FETs is also the cause of the high voltage spike on auto shut down with heavy inductive load that will kill the FETs every time . Do manual shut down and not run inductive load will probably save the FETs . I stop doing any more with the EG8010 and find the NEW rev 11.3 control board works better and use the new rev 11.3 main board with RUI FETs from Powerjack in China .

dickson Posted November 12, 2022 Author Share Posted November 12, 2022 You found a guy on Will Prowse's forum that built a functional inverter from one of these EG main boards? I'll bet it's rare. A 9kw EG 8010 base inverter is I think the max for DIY . Any higher load will cost a lot to find FETs that will not blow up by Miller capacitance . The need to find a protection circuit to protect the FETs from high voltage spike running inductive load will cost a lot in research . When the FETs blow up at over 10kw the cost of replacing the FETs and mainboard and control board and LF driver like the 15kw 20kw 25kw 30kw Powerjack is too much for me to do any testing of PJ inverter . Every used parts from Sean and ebay parts must be bench tested before repairing 15kw to 30kw PJ inverter . Just one bad FETs will destroy all the other parts that was good but now need to replace everything . People who has working EG8010 inverter do not talk very much . That guy with the 9kw do not tell how he do it . Quote Link to comment Share on other sites More sharing options...

Sid Genetry Solar Posted November 13, 2022 Share Posted November 13, 2022 The thing I notice as significant on those boards is the "maximum continuous current" of 190A. A single good TO-247 FET can handle that much continuous. And they've got 6 per quadrant (=24 total). Something's wrong with this picture when the "maximum current" per FET is literally 32A! At the very least they should be able to do what a TO-220 FET can do (generally ~100A each) which would be 600A. If they can't, there's drive issues. 1 Quote Link to comment Share on other sites More sharing options...

This is a good 24 vdc 5000 watts inverter for 349 dollars but a new 8000 watt AMG also 349 dollars and free shipping . I can repair most PJ inverter with the new rev 11.3 control board with a NEW complete main board rev 11.3 with matching ribbon cable and special order 300 dollar from China and free shipping .

dickson Posted November 13, 2022 Author Share Posted November 13, 2022 So, parts are available for a PJ model that shipped with a rev 11.3 control board? How many caps does the replacement main board have? All PJ inverter AMG 12000 watts or less with a rev 11.3 system will only need a rev 11.3 control board with LF driver and FETs and the rev 11.3 main board do not need replacing . Most PJ 15kw to 30 kw will need rev 11.3 control board with AC output board and LF driver and a new complete rev 11.3 main board with ribbon cable if all the FETs blow up . IF your PJ inverter is rev 9.0 or rev 10.3 or rev 11.0 or rev 11.1 then a NEW rev 11.3 complete main board with matching ribbon cable and a new rev 11.3 control board with LF driver will repair older inverter . The replacement rev 11.3 tiny main board has room for 4 capacitors . This is the main board use in the PJ 20kw with modify copper trace and modify ribbon cable that only match the rev 11.3 control board . Rev 11.3 parts are available from the Powerjack web site only in China by email to Jack . I can get you replacement parts IF Jack do not answer .

See his review is 100 percent positive . Do not post negative review on ebay or he may block you or send a picture of your inverter in a evelope and you will get a full refund from paypal and not sell you any more parts or inverter . I bench test all mosboard and LF driver before do repair . Quote Link to comment Share on other sites More sharing options...

The returned inverter are real and not a picture he sell for 149 dollars . He do not like buyer giving him a bad review on ebay . IF any problem then send ebay message for parts . He send a picture of a inverter in a envelope and not the actual inverter to a buyer on this forum because the buyer gave David a bad review on ebay . David will get you NEW rev 11.3 control board that are modify for older inverter if you send picture thru ebay message . Quote Link to comment Share on other sites More sharing options...
pilgrimvalley Posted November 16, 2022 Share Posted November 16, 2022 Hey All, I bought a PowerJack parts machine >>>> a 20k version 11.0 with ASL9 received today November 16th, 2022 from eBay for $470.23 including shipping and tax( with no guarantees no warranty, and no returns accepted)....looks totally intact but i have to remove the top yet...it is a 130 plus pound stainless steel beast like my other one. except my other one has the two built in lcd screens and this one does not.....the FedEx delivery driver dropped it twice as I was watching him unload it from his FedEx truck....he said it was heavy...I am sure., but their lack of handling care is pathetic!!!...I unboxed it outside in the 27 degree Fahrenheit weather....I do hear a loose bolt or something but have check more tomorrow when I can hoist it up to a higher workable position... this is the sticker on the bottom, it is a 48 volt split phase unit.....parts will be worth that I think, but may be a fully functional inverter as it was a return from a customer....definitely leery of buying any with a 60 day China shipping time ... this one came out of California in 5 days... different vender names but still powerjack equipment... it has 8 support feet on the bottom and all bolts seem to be intact on the bottom and all sides, so the loose rattle inside is still to be found....the ss case is strong and the transformer bolt and all still seems intact....

The RUI FETs if you need it also is FETs I have running my ASL9.0 15kw that never blow up . Any parts you need to keep it running I have or can get . Good to hear from you again .

dickson Posted January 26 Author Share Posted January 26 the boards with totem pole fet drivers is the best 002 boards The OzInverter use the EG8010 board with totem pole FETs driver up to 9000 watts . I run the Powerjack rev 11.3 control board with ASL 9.0 up to 6200 watts . The GS 12kw can do 12000 watts . There is now a lot of inverter that can do 12000 watts and even parallel two 240 split phase 12 kw inverter for 24000 watts . The new Powerjack 30 kw has a new control board that will diagnose any error before start up and has more powerful FETs according to Jack to try to solve the Miller capacitance . The new 30kw PJ should do 10000 watts . Quote Link to comment Share on other sites More sharing options...

No notable changes to the board have been done since version 6, and zero changes to the firmware have been done. (Yes, there have been significant form-factor and layout changes since then--but none of these have made any notable changes to the actual circuit.)

dickson Posted January 26 Author Share Posted January 26 Can pretty much guarantee this is not the case. Almost Everyone know that Jack distort how good and the new improvement is on the new 2 boxes inverter from Powerjack . He even raise the price of the 30 kw PJ to the price of the GS 12kw to show that it is better with 30kw compare to 12kw and thousand of buyer on ebay believe him .
