@Myl posted:It depends on how its installed; if you have an automatic transfer switch it implies you are keeping your existing converter so you can still get 12v and charge the batteries. Basically the shore power line will go directly to your inverter/converter. That is tied into your 12v bus so it can charge the batteries. What you are saying is that the line would go into a transfer switch which would then either go to the inverter/converter, or to the old converter.
Before deciding you want to go that route, make sure Renogy doesn't have some way of setting it to "charge only". My Victron has a 3-way switch for On | Off | Charge Only. And even then, I keep it on 100% of the time because it's controlled via a remote switch / screen where I can set the software to enable or disable inverting. I did remove the converter that came with my trailer, the Victron is on duty; I have to think the Renogy should have similar functionality.
Thanks for the response and excellent comments on what I need to check on with Renogy. The reason for choosing the Renogy inverter is I already have a Progressive Dynamics converter w Li Charging capability and wanted to keep using this unit if possible. I also was wanting to save some $$ in choosing the Renogy inverter vs. the Victron Multiplus since I am not sure I would use all of the Multiplus functions.
My current system consists of 2BB LiPO4 batteries, which I plan to expand to 4BB, Victron 100/30 Victron SC along with Victron Battery monitor.
Here is a link to the Renogy 3000w Inverter.
Dan as you mentioned I guess it depends on how everything is connected. Based on the YouTube videos I have watched, the Auto Transfer Switch would do what you mention above.
Hoping to remove our RV cover next week to begin doing spring de-winterizng and starting to look at how to begin my inverter setup.
Thanks
