Lener Posted December 25, 2022 Share Posted December 25, 2022 Power Jack Power Choke High Current Inductor 490uH 350A For Power Inverter DC AC…….. about $100 over the time I have collected some old transformers from old UPS , they have two different type of winding , wonder if the heavy gage winding can provide the same protection as claimed by PJ, after all PJ Choke looks like a toroid with heavy gage winding with input and output.

Sid Genetry Solar Posted December 26, 2022 Share Posted December 26, 2022 I honestly don't know if they're worth it, or just another sales gimmick. yes, they could possibly potentially "soft start" heavy inductive loads...but any huge choke is going to also "kick back". The root cause of the issue is poor FET drive in the PJ inverters...and if a choke works as a Band-Aid, then great! Quote Link to comment Share on other sites More sharing options...

I bought a smaller (50uh 20A)torroidal coil on Ebay and attached it to the L1 on my PJ which was running a 115V refrigerator. It seemed to allow the inverter to start the compressor easier.
