Samuel Posted July 21, 2021 Share Posted July 21, 2021 Can y change the voltage from 110 to 120 upgrade in the inverter Quote Link to comment Share on other sites More sharing options...
kuhrd Posted July 21, 2021 Share Posted July 21, 2021 You may want to add a bit more detail to your question so that someone can more easily help answer your question. What size and version of inverter are you asking about? I would assume this is a split phase inverter (L1-110v-N-110V-L2) and you are asking how to adjust the output voltage? Once you clarify what inverter you have, I am sure someone will be able to answer your question. If you are asking how to get both L1-N and N-L2 to both be the same voltage on a power jack inverter, that answer is more difficult as it may require adding turns to whatever transformer leg is lowest and testing with a variac until both sides are equal. 1 Quote Link to comment Share on other sites More sharing options...
Francel Posted October 25, 2021 Share Posted October 25, 2021 can you use 24volt dc terroid with three wire coming out of it its also supposedly rated 20/25k watts on a 48volt mainboard powerjack Quote Link to comment Share on other sites More sharing options...
Sid Genetry Solar Posted October 25, 2021 Share Posted October 25, 2021 If I understand your question correctly, the answer is NO. Technically, if you put a "24v" transformer in a "48v" inverter, it WILL run...at least initially. But any sort of surge load (or significant load) will result in blowing all the FETs. Been there, done that at least 3 times. (First 2 times trying to run a 48v inverter at 65vDC...third time trying to run a 24v inverter at 40vDC.) The transformer ratio needs to be at least somewhat matched to the nominal battery voltage--otherwise it's not going to work well. Quote Link to comment Share on other sites More sharing options...
dickson Posted October 25, 2021 Share Posted October 25, 2021 Been there, done that at least 3 times.

The highest I have my 48 v powerjack is 64 volts and run good but I shut it down when the FETs measure 135 degree F. and never at 65 volts DC .

Worth noting that the 48v inverters blowing up at 65-66v were the older "long mainboard" style, not the current design with 2 smaller mainboards. These blowups were caused by bad FET drive signals / crossstalk caused by poor design and FET drive. It is our experience with GS testing that the long mainboard is more of a liability than anything else--it will melt solder off the FETs at ~9kw due to poor board layout. That to say that the newer design might be able to handle higher voltage / power than the older design. Have not tested it though. 1 Quote Link to comment Share on other sites More sharing options...
