Battery Charger Trips GFIC with Gen power

Hello:

I have come across an unusual problem and need some advice.

The system consists of a 30 amp shore power system, a 3.5 KW Next Generation Generator, a transfer switch, and a AC panel with one master and three switches.

The shore power and the generator go into the transfer switch. The output of the transfer switch goes to the AC panel.

Switch one controls the Airconditioning, switch two the ProNautic 60 amp battery charger, and switch three controls some AC outlets with GFICs.


With shore power, air, the battery charger, and GFIC outlets function as designed.

However, when running under the generator, the following results are obtained.

Air, ok
Outlets, ok
Air and outlets ok
Battery charger, fail

Also, if the outlets are on and then the battery charger is turned on, the GFIC is tripped. However, the air is not affected at all.

I have also disconnected and insulated the AC wires to the battery charger. They do not cause the GFIC to trip when the battery charger switch is turned on with the battery charger itself disconnected.

It would seem that the battery charger does not like the generator for some reason and will also trip the GFIC but still allow the air to work?

Any insight would be appreciated.

Call Nextgen, get hold of "Gino". he can tell you in a sec if there is a conflict with the genset. He delivers those so they can be wired in a number of ways. he'll want some details.

Turns out there was some sort of problem with the battery charger. Promariner has done a great job honoring the warranty. They shipped out a replacement the same day via 2 day air. It is installed and working properly.
