I have been using a D250SE for a couple of years now and am very happy with it. Recently I installed two 100w solar panels on the roof of my van. Since the CTEK has a solar input with a built in MPPT charger I thought this would be a great idea. The specifications of the D250SE say that the maximum voltage of the solar panels is 23 volts. In todays standards this is getting quite low. The solar panel technology is making solar panels far more efficient than a few years back. I reached out to CTEK's support in order to find out if my panels would not damage the CTEK charger. Sadly, their responses were not very helpful. I got the feeling they were answering my questions in such way I could not hold them responsible in the case my solar panels would damage the CTEK charger. I reached out to tech support of the panels and they were a much greater help. In the end, my solar panels are not supposed to damage the CTEK charger and went ahead and installed them. Until now it is working great (a few weeks in). Since the 23 volts spec of the CTEK is a bit on the low side these days, it would be great if there was some kind of "box" that would prevent the solar panel output voltage to surpass 23 volts. That "box" could then be installed between the solar panels and the CTEK charger in order to protect it. Do you know of such a "box" or shouldn't I be worried about that?
