I don't have the inverter/charger connected up yet because the manufacturer insisted on 2/0 cable (I ordered 2 AWG in error). Should be this week. But I thought it best to take the step down converter for a whirl to insure it'll work right. So far, so good. It's been running for over an hour now with every light, stereo and pump (except slider) on. As the cute little ammeter I bought on Amazon shows, over 30 amps DC is pumping through the system. it's slightly warm to the touch and its fan is pretty quiet.
I had to disconnect the converter, of course. Not that's it's working or anything, but I didn't want the charger back feeding the step down. The converter has been on the fritz for months, with lights flashing all the time and it burning up batteries. That's why I started on this project prior to my PV's being delivered. I wasn't about to spend a couple hundred replacing something I'd eventually trash anyway.
What's impressive about the step down is that it's actually doing what it should. It's not just taking 24v/30A and wasting off 12 of those volts, it's actually taking that 720W of energy and converting it to 12v. I know this because I have a 15A fuse in front of it, so it's not drawing 30A.
So far, so good. Happy New year to all!
