FlexPower1 Use in an RV?

Postby AltPowerRob on Thu May 02, 2019 7:28 pm

Simple Q... I've installed several FP1's in small off-grid applications.. Can I take this pre-wire FX series I/C setup & mount it on its' side or on its' back in an RV?.. If so, it's a much better start to my system, than having to purchase individual components & link them all together (i.e. M series FX I/C, etc..).. Please advise. :)

Must be a big motorhome if you have room to mount an FP1. I think the magic smoke would stay in place if it was mounted sideways. One of the sealed inverter models would help keep the guts of that component clean. If it's a tight compartment, an additional cooling fan would probably be helpful. It could be tied to the same inverter aux port relay the internal fan is tied to, via an external relay.

The FM80 is not designed to operate in any position other than verticle so the FP1 has to be mounted on a wall or you have to take the FM80 off and put it up on the wall. Also, the inverter on the FP1 is not a mobile style with built-in neutral/ground switching. You can use the AUX port to drive a relay that switches the bond or better yet install an isolation transformer between the connection for an external AC power source (shore power). The FP1 was not designed for mobile applications so there might be other issues that crop up after bouncing down the road. It takes a bit more wiring but overall it would probably be better to just go with an M style FX inverter with the FW250 AC/DC breaker boxes. The FW250 IOB kit provides the AC input/output and bypass breakers. Wiring in the 250 boxes is a bit of a pain but they are compact so easier to fit instead of a larger breaker panel.

Thanks Gentlemen! I just thought I would inquire, but it sounds like the best way to proceed, using OB equipment, would be the M-Series w/ the FW250 setup as Kurt specified... I"ll post pics at some point :)

So any other suggestions on CC? or will the FM80 last as long as it's mounted vertical? I can make this work, as I like to stay in the same manufacturer's suite of components so they all place as nice as possible (including MATE3S, FNDC, etc..).. I"ll be connecting to a 24V LFP battery & then running some DC loads back through a 24:12VDC converter for the RV's DC needs... Need to run the AC unit & the coffee-maker completly off-grid :).. I don't believe that OB has any other CC solutions beyond the FM's?.. correct?

Thanks........... Rob

Hi Rob,

You can use the FM80, just keep it vertical.
