Hi all,
This is my first post. I hope it is in the spirit of what the forum is for. If not, please feel to delete it.
My problem is this:
I have a motorhome (RV) with a 12V leisure battery. This is connected to an electrical distribution system which charges it at 13.8V when connected to the mains electricity and also takes power from the battery when it needs it to power appliances in the vehicle. It works well.
I also have a separate solar system that charges the leisure battery. This can supply as much as 14.8V which is fine and all works well.
My problem is that sometimes I get a brief spike where the voltage reaches 15V for a brief second and this causes the main electrical distribution system to shut down and sound an alarm - usually at 5a.m.! I suspect it is when there is sun hitting the solar panels and the refrigerator has cooled to temperature and turns off. There is briefly then too many volts and the alarm sounds.
What I would like to do is insert a circuit/device between the leisure battery and the main electrical distribution system that will allow up to 15A to flow in either direction but reduce any voltages that exceed 14.5V on the battery side to be 14.5V on the main electrical distribution system side to stop it cutting off and waking me up!
I don't know if this is possible. I see that ready-made adjustable buck voltage regulator boards can be bought off Ebay but suspect they are not designed for current flow in both directions.
Its a while since I have wielded a soldering iron but am happy to have another go!
Thanks for your time, Ian
