My point was that the Trojans were NEW, should have been a lot higher than 50% and running the generator, powering any of these converters to charge
is a waste of fuel and expensive mechanics. It just "sort of" works. After four hours of charging they were still down around 75 or 80%. He would have to plug in at a park for 24 hours to really charge them and even that might not do it. The batteries reject amps when they are not pushed with enough volts. Pathetic!
He bought panels, a Tristar, a Trimetric, spend two days putting it together and I helped him set everything. The batteries ARE now charged. He can run the generator cloudy mornings if he needs bit of help, but he now understands that it does not really charge. Another voice in the wilderness.
Your Prosine can be programmed to do just about anything. It is the most complicated thing there is, but it can be turned into a real charger if you play with it long enough. I hate those things, after spending hours on the phone trying to help old, electrically challenged people thousands of miles away, who pushed the wrong buttons and changed the programming, trying to get their system working again.
