Shunts and Ground

Hi there,

Need some assistance wiring a FlexNet. I have three shunts. My understanding is with shunts I will no longer ground the battery negative (ie. battery side of shunt) as that would effectively bypass the shunts.

Can the Outback Inverter and Outback FLEXmax Charge Controllers use a common ground even if they are on separate shunts?

Shunt A) Inverter (AC Circuits)
Shunt B) DC Circuits
Shunt C) Charge Controllers. I will be installing a GFDI as well.

Thanks

Yes!

The GFDI will be the point where you bond negative to ground. As long as you only have one negative to ground bond the extra resistance from the shunts will not be an issue.
