Glad I am not too late! I was focussed on the current side of the panel and the voltage bit for the CTEK didn't click until this morning.Ahhhhh that's a bit of a bugger.... Teach me not to thoroughly read specs I guess.
Thanks for the heads up though... I never like smoke escaping out of stuff.
Except "Voltage" has 12V in, 14,8V out.Get the ring, they're the best item out there. I think the 'voltage' input just means you can charge a 12v battery from a 24v alternator like in trucks.
I have one of these charging the 12V LB from the trucks 24V system. I did have it as the solar controller, but have since moved to a Victron, mostly because of the monitoring. Now the Ring is just doing the 24V - 12V charging.Except "Voltage" has 12V in, 14,8V out.
The "input voltage - DC" range does look like it will work as a 12V-12V OR a 24V-12V system. The purpose of "Voltage" is very unclear though.
