So far, so good. lolMy breaker is upside down...works fine

If I ain't dead yet, it must be ok. Gotta replace it anyways. Pair of EG4's coming tomorrow.So far, so good. lol
Positive lead from a PV panel will be to the '+' marked terminal because the breaker contact resistance voltage drop will result in slightly lower voltage on other side of breaker switch. The negative lead from PV panel will go to the terminal marked with '-' since it will be the slightly more negative voltage compared to other terminal of breaker switch contact.
Until it doesn't. See MidNite Solar ETL Testing.My breaker is upside down...works fine
Looks like a 'jerry rigged' two pole AC breaker, attempting to make a 200A single pole breaker by connecting two 100A breaker poles in parallel.How about this breaker. My batteries are connected to load, inverters to line.View attachment 117256
AC breakers do not have polarity and should not be used for DC current. For 48v battery line you can get away with it, but tying two breakers in parallel to get greater current is just bad.Didn't want to mount it upside down, does it really matter?.

What is this "~" symbol?I probably blown ~15 fuses in my life.
It means approximate.What is this "~" symbol?
If this is a legitimate mathematical symbol, what does it mean?
Thanks in advance..!
It also means ac.~, doesn't it mean AC?
Thanks John, much appreciated (approximately) ??It means approximate.
YupSo these breakers from Signature Solar are OK to use.
I typed something to the effect of I had ~15 fuses blow in my lifetime.It is also approximately but in the context of voltage it is AC. The = sign where the lower bar is broken/dashed means DC. Never seen electrical equipment rated as approximately.
batteries are connected to load, inverters to line like I have it wired I hope.
