Herb, how much was the new pro sine? How hard a job to change? Thanks, Dale

Got the Prosine 2.0 yesterday, started some installation last night and will wrap uo this morning. Cost from MajorPower.com (New York) was $1448 plus shipping and no tax to California.

Installation is quite easy (replacing Invertrex) (i.e., no new wire feeds into coach, etc). However if you picked a Prosine 2.5 or 3.0, then you would need to upgrade the feed from the batteries to larger cable):
1. Remove large access panel in battery bay.

2. Unbolt the inverter (rear screw took the most time).

3. Lots of 2/0 cable is coiled up behind the old inverter, so it is easy to pull out the inverter and set on top of (protected) batteries after the AC lines wire ties are clipped. Lots of Romex cable available after clipping 4 or 5 wire ties.

4. Clipped off romex. 10 guage is input, 12 guage is output to microwave, and 14 guage is output to outlets. Now the Invertrex can be set on the pavement due to long 2/0 leads. Hack sawed through 2/0 and left 6" stub on inverter should some future buyer want to test it, before opening it to change connections.

5. Inverter does NOT come with circuit breakers for AC hardwire output. So a small 2 circuit breaker box was purchased and I mounted in on the left floor of the inverter cabinet. 14 gauge is connected to 15amp breaker, 12 gauge is connected to 20amp breaker.

6. 10 guage wired to AC input in inverter.

7. Bought 4 feet (more than enough) of 10/3 Romex to wire from Inverter AC out to the breaker box. Why three conductor? Discovered that my $10 breaker box was two poles, so instead of splicing the one feed to both poles in the breaker box, I will just wirenut the one hot AC out line on the inverter to the red and black wires in the romex to feed both poles of the breaker box.

8. Trickiest part, for some people who don't have the tools, is the change the 6-conductor ends of the signal cable from RJ14 to use only 4 of the wires of an RJ11 telephone jack.

9. Maybe if I opened the Invertrex I would have found lug connections on the 2/0 cable. I had to take the coach to a battery shop to crimp on 2/0 lug connections
9. Attach battery temp sensor to the battery and route wire into
inverter compartment. Have not decided yet if I am going to drill a hole or crawl under the coach.

10. Inside the coach: The control panel is a different size from the Invertrex. 5x5 and requires a 3 3/4 by 3 3/4 hole. I plan to mount into the wood next to the main panel over the door. Will make a cover plate for the old Invertrix panel. Change RJ14 to RJ11 and connect.

11. I had an Invertrex AutoGenStart which I had to give up. Unplug molex connector and RJ14 jumper and sell with old Invertrex. (Keep the pigtail so it can be used to plug in another GenStart available from Xantrex.)

12. Test and program system. Much more control here than with Invertrex. First setting is AmpHours of batteries and battery profile number so that it can set its default charging parameters for your battery configuration.
