"By the way PowerJack should be paying you royalties. Seems they make a good product (the LF series anyway) but their language barrier issues cause them problems. "
Hi Duke, I only want their control boards, and that power card you have in the bigger units... twice the cooling than the 8000w and less.
Beyond that I replace the rest of it......., but they are better than the other W7 transformers for idle.... for sheer power without fiddling, the W7 is a lot better, but weighs 50kg. The weight is good, but the transformers are lossy and leaky. They will use 5kwh per day for nothing.... They share the same basic control and power boards. Different/higher/realistic current programming for the W7 to match their very chunky transformers. Can do the same in the PJ by bypassing some of the current around the CT.
Their LF series are basically very good, but their QC is wicked...poor, and the power claims are pretty silly unless you re- transform. The electronics are good, the trannyies are good, but under sized for the claimed output..... they will do it, but continuous to them is 12 seconds after about 5-6kw for yours I suspect. Their surge is very impressive too ... start anything.. very good.
But if they put all the bits in there, and tighten everything up, they should give many years of service, as they are inherently sound beyond their QC..... it would help if they didn't make every one different too.
The AC input goes to the front end of the board, and from there by relay to the switching system. From what I can read there, they want 220v input. I suspect they use transformers in series, and so give you two 110v outputs, independent from each other but for the centertaps.
If the AC is wrong, it just wont sync to it, and so nothing SHOULD happen.....( you Americans and split phase systems amuse me )..... so I think it is just a 220v unit with split outputs.
I would hook up 220v into the terminal block, and ignore the IEC socket.
I am very iffy at recommending these things as a charger, but that is what you bought it for.... but gee I worry about the change over from charge/bypass to inverter mode. It may be my transformers are too tight for it to handle the input surges.....
These things are not perfect, but incredible value for the money... particularly if you want to play with them.... the worst that can happen is a new pair of boards from ebay for less than $200..... It's in your court. If you contact the seller, they may help you to get iti right first time... they are usually very helpful.... and when it all goes wrong, they will probably help there too.
Pics of the insides would be nice to see too Duke.
Ross, for a cheap backup unit for you I would recommend the W7 6000/18000w unit. When you get all the panels up, you won't notice the 5KWH/day, and you will need to push every bit as hard as your selectronic to bother it at all... it has animal grunt...... but expensive on the idle... and nothing you can do about it other than retransforming it.... it ups's very well as the leakage stops the surge currents on change back to invert.
