PV System Layout and Parts
A solar electric system can be a simple, or complex, as you want.
Here are the basic components:
Combiner Box (to bring the wires from the panels together) - optional
Charge Controller (to keep your batteries from being overcharged - some
can also perform other functions such as turning lights on at night)
Fuse or Circuit Breaker (between the charge contoller and battery postive)
Fuse or Circuit Breaker (between the battery positive and your d.c. (direct
current) loads and/or the d.c. to a.c. inverter.
This fuse, if sized properly, can be used for both.
This is a catastrophic fuse which protect the battery(s) from self-destructing
in a dead short situation.
If you need to power up 120 volt a.c. loads you will need a d.c. to a.c.
And last, but not least, the proper size wire and cable, along with connectors,
to make all of the components come together.
