Not when you use the correct breaker.
Square D QO, QOU and QOB breakers NOT HOMELINE!! are are also bidirectional and rated up to 60vdc and 60 amps...
EATON HEINEMANN 250 amp GJ series breaker. A Canadian company. Very old school and very industrial quality. Maybe one each per inverter to bussbar and a seperate similar breaker for the Coach 12 volt system. The...
I am considering permanently mounting 4 390W panels on top of a 7' x 16' Cargo trailer and 6 additional 390W panels (3 on each side of the trailer) that are deployed using gas-springs. Here is a link to a simulator: https://www.gasspringsshop.com/gas-spring-calculator/.
The side mounted panels...
I'm glad this fact came out. The NEC (National Electric Code) is heavily influenced by the NFPA (National Fire Prevention Association). Fire and electrocution risks are probably higher off grid, especially DIY systems. I know my first system was.
I was responding the last 6 words from the OPs reply. "if I wired everything in series"
24 volt array, 24 volt PWM SCC, 24 volt battery, 24 volt inverter. He just doubled the capacity of the system by adding 1 12 volt battery.
Your PWM controller requires you to wire the panels in parallel with your 12 volt battery . I didn't read any specs that said this controller would step down the voltage from a series wired (24 volt) panel array to 12 volt.
Here is a link that might help. I'm sure Trojan has a comparable document.
Also remember that the self discharge rate of a healthy battery is minimal at those low temps because the chemical reaction is...
My system is mobile so I plan on using copper pipe pressed onto both ends of 2 or 3 layers of tinned ground strap to make the cell interconnects. @upnorthandpersonal did his cell interconnects this way.
Found these 4" x 6" x 1/4" copper bars in my old scrap bin.
Soaked them in Vinegar and salt for about 2 hours and they turn out looking like the top bar in the photo below.
The bottom bar has been wet sanded with 1500 grit wet paper until you can almost get a reflection.
The bottom bar in...
