School is in session!! :) Let me make sure I understand this. You have two towers on that rectifier. If one has two power supplies, then you would connect the positive from each power supply to a tower on the rectifier??? So you would have one power supply positive lead per tower???
One 30 Amp or 36 amp power supply, both tweaked to the exact same voltage output, to one tower. What is underneath, the base, is now rectified, one way voltage, at the combined amperage of the two power supplies. You now tie in your 2/0 gauge wire to the base, to run to a big A$$ fuse, and off to the batteries Positive posts.
MegaWatt power supply 33amp 36 amp and giagantor amp.To be fair... Mex did post this up in another thread, I did have to grill him a little bit via PM's, because my electrical savvy on power sources converted to dry camping hard core boondocking "get 'er done, save the time, save the gas, battery life being shortened maybe 5%, probably a hell of a lot less" on a couple of free T-1275's was not going to make my wallet wince one bit. I had a Honda EU1000i and a couple of Eu2000I's to run the 13.5k A/C, so all my bases were covered. Keep in mind, I camp pretty much solo currently, and my tiny 21 foot travel trailer can't really suck too much juice in 24 hours... 50 amp hour days would probably be pushing it.
Anyways, after enough cattle prodding by Mex, I guinea pigged out and bought one. And I am here to tell you, this is one mean little kick arse dry camping boondocking fast as heck battery charger, when I set mine at 14.8V. I'll have no problem, in most days, running this thing at the most, 30 minutes to an hour, tops, first thing in the morning, and let the 120 Watts of portable panel finish with all the easy work, now that the generator has done the hard part, after a couple of cloudy or rainy days.
Within reason... for my app, it is a straight out bulk charger... I have the solar panel for finish charging. I will run mine short and sweet. It will pull 8.1 amps, or try, on that little Honda Eu1000i, at the start, and the T-1275 will take it all, no problem.
The average nerd would be better off setting this thing on a timer.
I have run mine in measured 104F heat, and it does not get hot, and it maintains it's power source profile. You might need to tweak your voltage down accordingly for the heat, perhaps a 1/10th of a volt or more? Ask Mex.
To my way of thinking... a device like this makes a Trojan T-1275 and it's problematic equalizing, or a group 31, 29, or 27 a lot less problematic. I just don't know if this unit will actually make 16.0V for equalization of cells purposes, and it might be too heavy handed on the amps to attempt it. I haven't tried it yet, and I have an old manual 6 amp Sears charger that will give me 16.0V, at a safe amp level.
