12s ion is 44.4v nominal 50.4v full charge, you thing the lower voltage had a toll on the inverter ? I will have to tell you how it died soon it was probably my fault.
Nope, it'd just have a flat-topped sine wave under loads/low battery. No issues or concerns there.
The issue with a low-voltage transformer config with a high voltage battery setup...is that the transformer current ratio does not change. Efficiency starts to fall pretty rapidly, mostly due to the ferrites saturating--which starts slamming the FETs with brief deadshorts per cycle, etc., etc.
at 60v you mean, it ran so good on 60v thats what I plan to use my 12k on as well is 60v :S
also my fet temps where super low.
also run my magnasine 4448 inverters at 60v 😄
also my fet temps where super low.
That's a side effect of driving the FETs firmly and cleanly. We haven't had any overheated FET failures on GS inverters--no, they generally either work perfectly or explode! It's actually pretty amazing how cool the FETs run in the GS12...they barely need any fan cooling at full load.

With sufficient ferrite capacity (which there should be), that shouldn't be an issue. What I'm referring to is running a 24v transformer spec at 48v...which would be the equivalent of running a 48v inverter at 96v. Same ratio--but very different results!
O OK I understand now thanks!
