1111Aa RV3012M inverter installation photos

[David Brady]

Only that long cables start to behave like transmission lines -

they can be modeled with inductors, resistors, and capacitors.

This is only an issue if the signal is variable in time. Ninety

percent of the time this is true; i.e., the inverter is drawing steady

current and voltage from the batteries or it is supplying steady

I and V, but there are transients and there are time varying

elements that are superimposed on the long cables by both

the batteries and the inverters. Maybe this is what they're

concerned about.

I don't know why there would be any specific hard limit on cable
length. Cables that are twice as long and also have twice the
cross-sectional area have exactly the same resistance and voltage drop
at a given current. There may be a length where the required thickness
would be difficult to route, but I don't see the reason for any
specific hard cap like 12'. Not that I'm saying putting the inverter
35' from the batteries would be a good thing, or desirable, just that I
don't see any engineering reason for some unbreakable limit.

Kurt,



Sorry I can't help with the cable size, I'm away from the bus,

but I don't think the inverters are more than 10 to 12ft from

the house batteries. I'll measure it when I have a chance. The

house batteries are behind the tag axle on the curb side. The

inverters are in the second to the last bay next to the toolbox.

I think the cable run is around 10 to 12ft.

I have posted two photos from e-bay of a 2000 Blue Bird LXI 43


Wanderlodge, the address is pasted below and I have these photos in a

new album in the photo section, named 1111AaRv3012M

If the inverters cannot be more than 12' from the batteries, how does

this system work on a 2000 LXI ?????????????????????????



I only ask because I've been told it can be done, but no one has told

me how.



Xantrex said it can't be done but here are pictures of Xantrex

Inverters and they are at least 20' from the Batteries.



My last post on this topic I had decided to just put the new inverters

in place of the old ones. After seeing these photos I'd like to put

them in the same bay as the ones in the photo.



I'll call tech sevices at Ft. Valley in the AM.



Any ideas on who would know anything about this set up. Maybe you guys

with LX & LXI's could tell me what size cable is coming from the +
& -

posts on your inverters. The ones in the photos are Xantrex RV series

inverters, my new ones look just like em.
