Has anyone installed an inverter on their Mainship 390? We have twin Yanmars.
Thanks

I worked on a 390 that had the inverter installed under the floor hatch by the lower steering station was working good there.Has anyone installed an inverter on their Mainship 390? We have twin Yanmars.

We have a 2000 watt inverter charger on our 2000 Mainship 290.Has anyone installed an inverter on their Mainship 390? We have twin Yanmars.

Yes, when the fans are running. Not annoying like the AC or the previous inverter / charger that made a big humming noise. The air conditioner is by far the loudest.Thank you. Do you hear it running in the salon?

While this might be true, unless you are cruising or on long hauls, inverters are primarily used when on anchor/mooring, or even in the slip when not connected to shorepower. Yes, they are used while underway, making coffee, heating a muffin, ect, but MOSTLY not when the engine is hot. I say this because mine is in the ER, as I am super tight on space as it is, and this is the only place it makes sense without super long cableing.Best to locate inverters outside the ER if possible. Their output de-rates significantly with increased temps.
Since I first read this I have watched closely and have not seen any noticeable derate. It does make sense, so I will keep watching.Best to locate inverters outside the ER if possible. Their output de-rates significantly with increased temps.
Sure.... On my 390 mounted directly below floorboard, vertically, on the front of the firewall, as far to the starboard as possible, then just run the cables across the front side of the firewall to the batteries. Use, at least, cables that will carry 225 Amps...................Ken Ongemach BSEEHas anyone installed an inverter on their Mainship 390? We have twin Yanmars.

Interesting. My Xantrex Freedom SW 3000 is over 20 feet from the house batteries, but only 3 feet from our Cummins QSB. We never really tax the inverter and it is likely that I have never noticed the impact of voltage drop or temperature.When it comes to inverter/chargers, I find voltage drop to be much more important than temperature. It does absolutely no good to locate the unit in a cool location at the expense of voltage drop. My unit is located close to my batteries and is connected with 4/0 cable.
