I am a first time poster although I have been reading post on here for a week or two and I just wanted to post some pictures of the LF Power Jack inverters I just purchased on E-bay. They are both 24v/110v 60hz. One is an 8000w and the other is a 6000w. They seem to be almost identical except that the transformer coil on the 6000w is a little smaller/shorter and it has less Fets on the bottom H main board. It seems that the issue with the high idle drain mentioned in another post is not present on this one and may have been fixed, or perhaps I am looking at the wrong info.
The 6000w unit works perfectly so far and has charged my 24v batteries and I have tested some appliances on it. The 8000w was basically DOA. It will work as an inverter if you connect the 24 volt batteries, but when powered by the 110v leg, it does not power on in pwr save mode or full on mode. I have checked the fuses, the switch and even traced 110v getting to the control board from the plug, but when you flip the switch nothing happens.
After contacting the Chinese seller, I was advised to return for a refund, but . . . . I got this at such a good price that I am debating just trying to fix it myself, but I was wondering if anyone knew enough about these to help advise what my options are.
1)I have read some of Oztules post on here about his and noticed there were two transformer coils in that one. Also on a post online
it shows the 6000w with two coils and the 15kw with three. Could it be the difference in 50hz vs 60hz that determines whether they install one or two coils?
2) If I were to buy a replacement control boards with higher ratings (15kw) could this one handle more continuous power like the ones with two coils do?
3) If I get the 48v control card will I be able to then run it on 48volts, or would I need to make other changes ie. add another transformer coil?
Thanks in advance for any info.
