Confused

Added a 1000w inverter to run the residential fridge. Runs the fridge great, wired it to the Xantrex 458 12 volt input terminals. Have a system monitor checking power and amp use. All works great, but when the fridge turns on, the monitor now shows zero amps and no power used. Every thing on 12 volts still works, voltage is 13v.

Are you sure the monitor isn't just hooked up to the Xantrex458?

Positive, the Exantrex draws current just like the dedicated fridge inverter, they are in parallel.

Do you have a shunt in the negetive battery cable ?

If your monitor plugs into the large inverter and has no shunt, it will only read the large inverters usage.

Yes, a 100 amp shunt, that works perfect unless the fridge inverter powers up the fridge

Did you install a chassis ground cable to the 1000 watt inverter ?

Current is going around the shunt.

Twin boat, you are right on, installed a chassis ground this morning, working perfect. Thanks to you and everyone on this forum, great bunch and sounding board.
