Warren,

Sorry for delay, but I just saw this.

The positive side bus pulls power from the battery side of the Blue Systems battery switch. That way I can shut off power to the Magnum but still have power to the 12 volt system. Nice for maintenance.

The negative side bus pulls power from the battery side of the shunt.

You can see this in the diagram I sent you.

Dave - I have a 2016 International Serenity. 25' FB. I did notice my old main is different from yours. Curious to know how your DC side gets powered.

Hi Warren, I sent you some pictures and diagrams in a pdf to your email address. Let me know if you have any questions. BTW, what is the year and model of your AS. Just curious. Dave

Dave -

What you did sounds exactly like what I am doing. Only exception is I am NOT using a Magnum Hybrid. I also was going to keep the existing ATS that shore / gen comes into. I was planning on running it to the new Main ( Sub-Panel ). It will have a 30A for main and 20A for AC. The 30A would then run to my inverter which is pass-thru and also has built in ATS. It will then output to the old Main 30A in the Progressive Dynamics. I will also move the old hard wired outlets from the original inverter to the 20A breaker the AC use to use. My email is wponder11@gmail.com. Would love to see any pics / diags. I can send you mine also.

Hi Warren,

I am not sure what I did would be relevant for your situation, but let me explain what I did, then you can decide.

I replaced my converter with a Magnum 3012 (3000 watt) hybrid inverter/charger. My shore power (or generator) comes into the trailer and passes through a hard wired EMS. It goes from there to a small sub-panel which powers the A/C heat pump unit with a 20 amp breaker and powers the inverter/charger with a 30 amp breaker. When on shore power, the Magnum passes through the ac electricity and feeds it back to the original Square D panel where the ac electricity is parceled out to all of the trailer's circuits except for the A/C. When I am using the inverter, the Magnum produces ac power from the battery bank. Because the Magnum is a "hybrid" unit, I do not need an ATS.

That is a quick explanation. If you would like more details, send me your email address and I can send you some pictures and diagrams.

Good luck! Dave

Do you have more info on how you repurposed your Parallax panel as a sub panel? I am about to upgrade my inverter to power all my outlets. I was hoping to leave the existing ATS in place. Rewire from the current 30A breaker into a two breaker sub panel with a 30A breaker from the ATS. I was going to add a 20A breaker to it and relocate the AC there. From the new panel / breaker wire into the inverter, then from the inverter into the original 30A breaker. I was going to move my outlets inverter hardwired set to the old parallax panel and old AC 20A breaker. This should allow me to power all my outlets via inverter and pass-thru when on shore. My only concern is neutral ground bonding and also the old converter getting powered when it will no longer be used.

Thanks,

Warren
