24VDC Auto Transfer Switch
24VDC Auto Transfer Switch
(OP)
Hello,
I am looking for a 24VDC Auto Transfer switch to switch between two 24 volt battery banks inside a vehicle. When the main battery bank/supply either shutdowns from an open circuit or looses so much charge the other battery bank should maintain the system.

1. Im sure it's standard solution, but of course very expencive.
2. You can use simple diode bridge.
3. You can buid it with simple relay with two CO contacts.

If it is acceptable for both batteries to discharge together, use diodes.
For charging check the battery isolatotrs.
Look for information from motorhome and camper forums. Twin batteries are common in these applications.
