It actually may be a good thing that you took a crack at this, for educational purposes. It's a good way for some people to truly grok what's going on.
That being said, your doc needs a lot to really be a valid working document.
I would suggest you take your drawing and one of the reference drawings and see what is different, missing, or connected differently. That should reveal some areas where your design has holes and will highlight design choices or omissions pretty well. At the very least it is a pretty comprehensive checklist of thing to consider.
I think at the end of the day, you'll probably decide to take your components, translate them toward your preferred reference design, and evolve from there, rather than trying to re-invent the wheel
from your current
Also, it may be helpful to group things (perhaps dashed outline). For example, I think you are assuming a DC bus. I think that might be the two blocks following the BlueSea DC fuses
. But, I can't tell at this resolution and originally thought those were fuse blocks for Class T fuses. I am still not sure.
I think you mean to have a bus bar between the Multiplus and the Batteries
, though I am not sure of the connectivity or where the batteries
would be fused/switched relative to the connections. Also, it is not clear how you would fuse this. (Saw your comment about including a bus bar after typing this).
There are a bunch more things like this (e.g. how you bring in the DC via the Orions, what actually controls the alternator
disconnects and the battery
disconnects; how your DC panel fits in) in addition to the things Jedi raised.
But, it's a good start and a good exercise, even if you may have to retrace a bunch of your steps.
One other bit of advice
- spend adequate time doing/optimizing the physical layout once you have a solid design. You'll find things like cable lengths, mounting clearance, switch and fuse access, etc. depend on this, and these are the things you need to order/build/install. As a simple example, reorienting my battery disconnects relative to my batteries and Multiplus, relocating my MPPTs a little bit allowed me to remove 1.5ft from each of my 2/0 red cables
and 1 ft from each of my black 2/0 cables
. With 6 batteries, that's 15 feet of cable and a lot better airflow. It would really suck to build a bunch of cables with lugs and have to rebuild
them for a different length.
