My RE system: Radian fpr-4048-01 Honda eu7000is generator

Generator hook-up not working

Post by Ponderosa » Fri Sep 18, 2020 8:39 am

I am having trouble with my Radian 4048A-01 system recognizing my Honda EU7000is generator. I am wondering if I have wired it up incorrectly. I am coming off the 30 amp plug with 2 wires and a ground. So with the three prongs on the plug, I have the black going to L1, the white going to L2 and the ground wire to the ground bar. I notice on the wiring diagram there is a neutral wire running from the generator to the neutral bar. What's that all about? Now I am wondering if this missing neutral wire is the issue and if so where would it connect to the plug?? Could the neutral wire be the one I have to connect to the the third prong on the plug where I have the ground wire connected Can anyone who has hooked up a generator, specifically a Honda 7000 tell me how they did it?

The EU7000is operates in either 120V or 120/240V mode, switch selectable.

The 30A, 3-prong connector is 120V single phase only. The 120/240V section of the outlet array on the front panel has a 4-prong connector that provides 240V split phase when the generator is switched to 120/240V mode.

I'd highly recommend a careful read of the manual regarding the output operation modes. The EU7000is is smart about protecting itself, but there are conditions that could lead to needing to replace very expensive inverter boards.

And use a voltmeter to verify the voltages.

Thanks for the replies. I have amended my post slightly with a more accurate description of the connection from the 3-pronged outlet to the load center. Raysun, you mentioned the four prong two phase plug 120/240. Are you suggesting that the inverter only recognizes two phase current? or are you saying that I need to have the 120/240 switch turned off before the 3 pronged single phase plug will work, and that the inverter is ok with single phase power coming from the generator. By the way when I manually turn the generator on the Generator icon at the bottom right hand corner of the Mate3 registers 134Vac. But the yellow light blinks indicating that the connection is just not right.

.
The generator is capable of 120V single phase (Hot, Neutral, and Ground), or 240V split phase (L1 Hot, L2 Hot, Neutral, and Ground). In 240V split phase, each Hot (L1, L2) is 120V with respect to Neutral.

In the wiring scheme you describe, the black wire (120V hot) is connected to L1 (hot) on the inverter's AC IN. The white wire (Neutral) is connected to L2 (hot) on the inverter's AC IN. This wiring scheme will not give the L1-N-L2 240V split phase the inverter is expecting, so the AC IN will not be connected.

You need to have a line cord rated at 30A with an L14-30R 4-pole twist-lock plug at the generator, connected to the 240V outlet. The wiring will be Black (L1 hot), White (Neutral), Red (L2 hot), and Green (ground). Wire the leads properly into the GSLC, and AC IN will connect without issue.

Make sure the generator voltage switch is set to 120/240V (not 120V only.)

Am assuming you have power at generator (check breaker)
Check Mate AC input is active. You only get. Yellow like if not On as I recall.

Thanks for the info . I am thinking that running a 3 wire #10 from the four prong socket will do the trick. Shall pick up a 4 pole twist lock plug and give it a try.

Hmmm.... planning on leaving the circuit ungrounded?

The plug will have a ground as well. Four prong- Black-hot Red- hot White- neutral and the ground wire.
