What I want to do?
I live full time in an RV. I want to run everything from the batteries with inverters, even when connected to the grid. When batteries go below certain point, start the generator (20kva) and charge them. I also want to use solar panels so if the solar panels don't charge the batteries start the generator. For the 220v appliances I will need to be split phase (I think) so they can work correctly that's why I think 2 Victrons will work in this way.
What do I currently have?
I have the generator already, it is a 20kva genes and I also have an inverter that I want to replace with a couple of Victrons. I don't have batteries nor solar panels and I have the wiring in place already.
What do I need?
Inverters: I've been thinking in going the 48v route for the inverters so I don't have to use heavy gauge for the wiring but I can change this, is not set in stone. Batteries: I was thinking about using battle born batteries but I can use anything else I can get my hands on for lifepo4 on 48v configuration. Solar panels: I want to use mono cells and 375w panels (or bigger if I can get my hands on them) 375w is easy to get around where I live. Wiring and others: I have not clue what cables might I need and I what else I might need.
Another thing I'm wondering about, should I use my alternator to charge batteries? If so I would need to change it as the on I currently have is only 100A and won't do much to the setup I want.
If one of the questions you have is how many watts you are using I can't give a specific number but I can surely tell that I can have the mini split running and also the range could be on so that's not small potatoes but I can have them alternatively on if that makes a huge difference (which I think it does).
Other than that I have a water heater (a 1500watts unit) and an electric BBQ that it is 2000w. None of this things will be on while another large is on as well so I guess that all this is to say that I biggest load could be the mini split running and maybe some other minor things.
Thank you for reading this huge post and I would love if anybody can help me with this as I would need to solve this pretty soon and I have no idea what to do (equipment wise).
Thank you so much for your help in advance!
