New Voltage Inverter Install

Hi,

I have a 220v boat and decided that I needed some 110v options. I just purchased a 110v inverter and the best place to mount it is right next to the 220v inverter. I was wondering if I could just pigtail some short lines from the 220 inverter over to the 110 inverter for the 12 volt source.

Does anyone see a problem doing it this way or should I just wire the new inverter separately?

Thanks for the advice.. It seems I only have questions...

Meck

Properly using existing the DC Supply (to 220V Inverter) to also power the new 120V Inverter may not be worth the trouble.

EG:

The existing DC Fuse & Cable will have to have been sized to accommodate the new Inverter current.

You’ll probably need to put in a Double Pole Double Throw (DPDT) Selector Switch, so that only one Inverter can draw DC power at any time.

I agree with Gord. Inverters can draw so much power from a battery that, to be safe, their conductors must be very carefully sized and installed in accordance with the manufacturer's specs and with good industry practice.
