Hi,
I am new to this Forum. My Fiancee and I are planning on building a Tear to take on a 4-6 week journey cross country for our honeymoon next fall and I have some electrical design questions for those of you who have already built your Tears.
I want to be able to use DC power and AC power regardless of whether or not I'm connected to shore power. I would also like the system to switch over automatically when I connect to shore power.
This is how I would like the system to operate:
WHEN CONNECTED TO SHORE POWER:
Shore power charges on-board batteries.
110v AC to the high voltage system from shore power source
12v DC (via an inverter) to the low voltage system from shore power (not through batteries). I don't want the batteries to provide low voltage power when connected to shore power.
NOT CONNECTED TO SHORE POWER:
Tow vehicle charges batteries
On-board batteries provide 12 volt DC to the low voltage system and 110 Volt AC (via an inverter) to the high voltage system.
Is there a device that is "smart" enough to isolate the on-board system from the tow vehicle when using shore power or a generator (other than physically disconnecting the harness to the tow vehicle)?
Are there harnesses that have pins for 12Volt power in addition to pins for the turn signals/running lights/brake lights?
Thanks for your help.
