I have fitted a 12 12 30 (Smart) to my caravan to charge the house battery and help with the fridge load using the tow vehicles alternator.
The Smart version is great with programmable voltage sensing capability but 30a is just too high for the wiring I have and the distance it travels. I believe the 18a equivalent would be ideal but they don't appear to be available at the moment (at least in Australia).
Is it possible to cap the output amperage?
Thanks in advance.
