I have the ds250 dual paired with the optional unit I believe is called the bypass.

It works great. I have 6 volt golf cart batteries that I purposely discharged to 50% to see the effects. It was charging at over 60A and continually adjusted the output as batteries reached the full charge. It will also boost or drop voltage dependent on the state of charge.

The reason for me to by the pair was to quickly charge the batteries and not have to bring a generator. Before installing this combo, I did a test on the camper 40A charger. At 50% I was only receiving about 25A which adjusted as I got close to charge. I would have to run the generator for several hour to get to get close to fully charged.

I have a DC fridge and a cpap machine running off these batteries. So quickly charging these batteries is important. I run to the store and when I return battery capacity is much higher, if not fully charged.

I have not found the need for a solar panel yet. The good thing with the solar input is that it will recharge your truck batteries after house batteries are fully charged. Great for longterm boondocking without generator.
