My current ac subpanel that resides on the charger/inverter switched output contains a relay crammed into a corner. My suspicion is that it isolates ac neutral from ac ground when the output is from shore, and connects them when the switched output is from inverter. Or perhaps vice versa.
Has anyone encountered a similar relay and deciphered it's function, and is that function really needed?
I am confronted with a crashed original (1995 vintage) Heart Freedom 20 inverter/charger. I am looking at the choices that will fit into the existing under-bed mounting location, staying with the older modified sine wave technology which has served me well in the past.
My options appear to be the Xantrex 458 and the Magnum ME2012-20B. Both are 2000 watt - 100 amp.
1. I am leaning toward the Magnum for two reasons.
There seems to be a lot of people on the internet unhappy with Xantrex 458 reliability in recent years.
2. The Magnum -20B version has internal breakers for the two inverter-driven circuits, allowing me to discard the ac subpanel that the Xantrex requires.
Mr Wizard, thanks for the good advice. I also use a Vz wireless hotspot. Recently upgraded from the old flaky 3g model to the 4g model. The 4g model really helps with videos when it is in 4g space. And it does not have the problem of buggy connection with Vista. I have been looking at the Google Nexus 7 Wi?Fi.
Back on topic, I have just about resigned to the fact that I will have to buy a new inverter/charger. Xantrex will not consider repairs on my ancient Freedom 20.
I have my eye on Xantrex 458 or Magnum ME2012. There seems to be a consensus that the Xantrex has lousy lifetime/reliability, and the Magnum is a better unit for the money. Available mount constraints may be the ultimate determinator.
Either way the cost less installation will be $999 - $1200 range.
Thanks for you help. Xantax called me today and clarified the fuses location. I have not had time today to check the fuses (and I saw your offer too late), or I would have probably bought your board.
I can turn off a/c. Can I unplug the remote and turn the inverter manual switch off to safely remove all voltages without disconnecting the 12 V cable? The cable approach is going to be a bear as I have 8 batteries packed into a 4 battery compartment, and I stupidly did not install a cout off knife switch..
Ok, thanks. I need more help.
First, we are talking about the Heart Freedom 20, vintage 1995, correct, just to be sure.
I have removed the side covers. I see a small board, longer than wide, oriented parallel and attached to the top cover. There is a second much larger board oriented perpendicular to this.
Looking at the smaller board, I see nothing that I recognize as a fuse. Of course, fuses can be any of a myriad configurations.
Now that I have a restricted view of the small board, can you give me a more detailed info about where on the board and the appearance of the fuse.
That would be a great help. Trying to save $1000+!
I have a set of 275/70/22.5 Hankook AH-12's on order now to replace my 7 yr old G670's. In my area, they will cost me $2,740 out the door.
2740 sounds like an excellent price if for six tires, including stems if req'd, mount spin, and install!
