My names Jesse Fuchs and I own a 30ft Airstream Argosy that I have stripped down to the bones, and I am slowly poking away at rebuilding while Covid-19 has closed my local watering hole.
It’s about the time to start planning the electrical system so I can size the wire, fuses, and disconnects. I have cruised the forums the last year and know that these are tough places for someone to drop into looking for guidance, especially if I have overlooked something important or decided to buck any of the current trends, alas, I am reaching out for help from the Victron Gurus. I apologize if something is obvious and I have missed it. Please bear with me.
I have attached the basic Electrical plan. The first thing you may notice is that, for cost reasons, I have decided to not use Victron batteries. I just cannot justify spending 12 000$ more.
This brings me to my first question.
#1 Other than connecting to the Lynx Shunt and monitoring the batteries temperatures with the Cerbo GX what am I missing?
#2 I want to simplify the system and stick with Victron so I have decided to opt out of using the Simerine monitoring system. One thing I really like about the Simerine is that it can monitor current draw of loads. Am I able to do this with the Cerbo GX or any other Victron equipment and then see a visual on the GX touch?
#3 This is more of a solar question, but I have organized the solar panels in 3 strings of 2 series panels to avoid shading issues. Should I use one MPPT 100/50 or three smaller MPPTs in parallel?
#4 I have done some very loose math and according to my load audit, for 3100w I am 100 ah short and a bit overkill on solar. I just want to avoid roof penetrations in the future so I would rather upsize. If there is a more efficient way that is glaring at anyone that I am missing? I’d love the tips.
#5 I do have a BMS 12/200 but thought that it was easier to go with the Orion 1212. If anyone needs a BMS 12/200 or it actually can be easily integrated for tow vehicle charging, please let me know.
# 6 Will there ever be a way to incorporate the Garnet seamaster levels into a Cerbo without having to utilize all of Kevin Windrems hard work?
