Definitely! Why do you insist on duplicating the charging system. Converters have no temperature compensation, and Airstream moved away from TrippLite to Magnum for the Interstates a couple of years ago.

If you intend to keep your batteries properly charged and simplify your installation considerably, them a Magnum is the only way to go.

Interstate owners have numerous complaints about the battery charging of the TrippLite, but it's your dime!

Been following this thread and must say the $$ diff. Magnum/Tripp-lite is substantial.

Just rebuilding an old AS and I'm really thinking about all-DC but for a couple laptop charging stations and maybe one AC plug inverted for re-charging devices like
razor, flash lights etc.

Just seems that a honda gen set answers a lot of power issues but I can only envision Air Conditioning and Micro wave as the problem here and I can see that to run either off the battery bank is going to cost some serious bucks. A good lap top can run any entertainment system through a moble-pre modem linked to the coaches stereo for any application.

Still this is a great thread, thanks

"Been following this thread and must say the $$ diff. Magnum/Tripp-lite is substantial."

There's also a substantial reason for the price difference.......it's called performance, quality and overall better operating characteristics. It's like using a Progressive Dynamics converter over a Parallax. Price difference.....yes. HUGE difference in performance............YES!

Like the old guy says........."Ya pays yer money and ya takes yer choice!).

Simplified system

Choosing the right components will not only simplify your installation, but will also provide you with far longer service and better performance.
I am trying to do this with my rebuild. Admittedly it only has a 30amp service, our AC/heater is only 840w and we have no microwave (would rather use the space for a 600w toaster oven) so we have no individual item over 1000w.

But that means we have a single switch (between shore and generator), 110v runs through the Magnum, a single distribution panel with 110v and 12v sides, the ability to charge the batteries from solar (we have gone with a Zamp portable panel, but will consider a flex-panel install later), but also the batteries (using the Zamp connector) can be plugged into a Deltran battery tender when the entire system is shut down, rather than needing a 30amp shoreline.

......actually I think this can be simplified even further. I am going to use a Eu2000i so if the 110v transfer switch is replaced with a single 30amp connector I can only ever plug in shore OR generator, so don't even need a transfer switch.

Lewster, can you explain what you mean? I'm not sure which systems I'm duplicating...

Anyway, I think I've settled on the below system design (going the sub-panel route with the charger+inverter+transfer-relay option).

I'm going to give the AIMS Inverter Combo unit a try and see how it works... I'll run it through it's paces as I complete the rest of the renovation to see how it holds up. If it sucks, I'll send it back and get a different unit, but for the price I figure it's at least worth a try.
