So this is not really a solar question, but more of an install question. Yes if this new Victron does what it is supposed to do, I will add solar. Maybe on this rig or I may be upgrading to a larger rig to fulltime in. Right now I just want to make sure I get this inverter/charger installed correctly as not to damage any other systems or light the thing on fire. I'm using 3 120ah flooded lead acid batteries. Kinda just want someone who has done a similar install to check my brain and see if I am putting things in the right order.
Ok, trying to get a grasp on this. It finally showed up just as I was leaving for a 2 week trip in the car. So the boxes are in the garage unopened.
I want to see if I have a grasp on the changes I'm making and check my thought patterns.
2006 Winnebago Journey 39k. It came factory, at 50 amp and a 7500 watt generator. It also has a Dimensions 2000 watt inverter/charger that has failed. (charge still works but no invert)
On the old setup, the shore power cord and generator wiring go to the ATS which is shore power priority. Then the 2 120 volt lines go into the main distribution panel that has a dual 50 amp breaker. It also has a 30 amp breaker marked "inverter" that feeds an sub panel that is just outlets and the refrigerator. If I trip the 30 amp inverter in the main panel off, the charger quits and everything on the sub panel quits. So I am assuming that it feeds the 120 to the charger and accepts the 120 from the inverter (when it worked)
If the inverter senses any shore power, even 15 amps it just over rides and stands by. Disconnect shore power, the inverter would start. It had one 120 output that ran over to line 1 in the ATS, meaning only 1/2 (30 AMp side)
The new inverter Victron MultiPlus II 12/3000/120-50 2x120V is a pass through and has 2 120 volt legs, meaning in theory, it will power everything in the RV. Also, if I am on 30 amp, and draw more than that, the inverter will add watts to make up the difference (assuming the batteries are up.
So where I am a little perplexed is the new install. I am thinking that I leave the shore power and generator wired where it is, take the output from the ATS and run that to the input of the passthrough inverter. The output of the pass through goes where the old output from the ATS, directly to the distribution panel. 12v Gets hooked up just like it is now. Positive and negative into the Victron MultiPlus II 12/3000/120-50 2x120V and then just eliminate the wire that came out to power the old inverter charger. (don't need 120 to it anymore as it is a pass through)
It also has an Intellic PMS. Which must be powered by the 30 amp breaker in the main panel. I spend a lot of time on 30 amp, so I don't want to loose the EMS but want to make sure the pass through inverter adds the watts I need. It normally would be short duration, but I can't tell you how many times I had to reset the parks breaker due to trying to get just a little too much out of it.
I'm thinking doing it this way the main panel will always think it has shore power or generator, even if only on the inverter. The inverter should pass 120 to both legs as long as I don't exceed it's limits.
As I say, it's still in the box in the garage, but my brain has been working on how to set this up. Maybe instructions will be very clear, but I've never counted on that.
Am I on the right track
