    Circuit breaker question- Voltage rating?

    There is a lot of info on sizing a circuit breaker per amperage. It seems the consensus is that the breaker amperage rating should be about 1.25 times the conductor sizing. But I can’t find anything telling me where the voltage rating of circuit breakers comes in. Also, there don’t seem to be a...

    Looking for feedback on my system diagram. General feedback and also feedback on where to put circuit breakers.

    Yes, you’re right of course. The wire sizing calculator I used specifically said it was for sizing just one wire but I should have put in double the length. The inverter manual doesn’t recommend a wire size strangely enough.

    Thank you! You have provided a lot of good feedback. I’ll look more into breaker sizing and pick up a couple of those. interestingly enough, I fired up my system (with only one pv panel connected just to test it out) for a few minutes and used a clamp meter to see the amperage going through...

    I've been loving learning about off-grid PV system design, haven't been this interested in a hobby in a long time! The goal of this system is to learn about electrical systems and to hopefully have a functioning source of power to run a refrigerator/freezer in the case of an extended grid power...

    Want to power refrigerator and freezer in case of grid power outage for several days, please let me know if my calculations are correct.

    Yeah, I'm not sure why it is such a large number. It is a subzero fridge/freezer so maybe the fancy ones like that take more power. I tool the yearly KW/hr rating from the manufacturer so it probably pretty close.

    Thanks for the response. I agree that the 5 days without sun is very unlikely, especially here in Phoenix area. I will probably reduce that to 1 day. I can't really afford more anyway and don't want to go too crazy on my first system.

    So I have been watching lot's of Will's videos and they are super helpful to a beginner like me. I also found a site called PVeducation.com which did a good job of spelling out the process of sizing your PV and batteries. I attached the image below of my calculations. I am a complete beginner so...
