No its not in the guide.  But yes, I felt it was a  necessary post as this is a very grey  and confusing area..

I originally bought one 3 years ago,  an HF 3KW inverter and it was pathetic.  They were the first of the Asian made inverters and had many problems, not the least allowing entry of a cockroach which walked over the overload sensing circuit, fried the beast and placed a short across the circuit, shutting the unit down!!

I have used those toroid transformers in Ham Radio applications, expensive,  but will beat any switching power supplies hands down, which can create a lot of spectrum interference, esp the HF versions.

I need to correct the typos LOL, my ancient hands  are somewhat arthritic! 🙂
