Bob, A 100W solar
panel is not going to provide 30A, more like 8A with optimal conditions and using an MPPT
controller. You may be looking at the maximum amperage your controller is rated for, you would need over 350W of panels
to get close to 30A. Use Watts = Amps x Volts to figure it out.
and breakers protect the wiring from being overloaded, for example the maximum size breaker for a #14 wire would be 15 Amps. Get a copy of Nigel Calder's Boat owners Mechanical and Electrical
manual and all will be explained.
I don't see the need for the AC to DC converter as drawn, just use the battery charger
when AC power is available. As for the AC wiring the best I can say is read Nigel Calders book then start over.
Beautiful, absolutely , schematics to engineering standards no. These are more like very good " "installation diagrams " rather then schematics.
Non professionals tend to draw " physical wires" , a proper diagram is a " circuit schematic " so things like ground returns etc are typically iconised. Furthermore the current
trend is for hierarchical schematics so you progress from black boxes to individual schematics. This allows the engineer
to focus of the section of interest without having to extract its relationship with all the other parts
of the circuit
I can read an understand complex micro controller , digital IC circuits in half the time it takes to analyse such " schematic drawings "
But they are beautiful to look at, but when I look at sanderos drawings I can't see the circuit for all the colors !!!
If you are designing a DC system of above average complexity , I suggest you familiarise yourself with a good CAD package designed for electronics
or preferably electrics. There are a few free ones about. Concentrate on getting the circuits right. Then you can always build net lists , or wiring connection diagrams from that .
If you do the nomenclature right, the resulting net lists will give you a proper cable referencing system, that ties directly to the schematics
Arrange your diagrams in hierarchical order , draw " black boxs" first showing interconnecting circuits ( not wires ) then burrow down in subsequent sheets
into each section.
