They should be fine for a disconnect, I just wouldn't switch them under a heavy load unless it's an emergency situation.
I reduce my loads so they they are minimal before disconnecting if I need to take an array offline; you could also reduce charging current to 0 in the settings.
I would always have a disconnect.
I'm by no means an expert or certified electrician but have learned an incredible amount of info from the experts on here over the past year.
Ahh OK makes sense, ya it was mid day and each mppt was pulling in 5k so ya heavy load lol

It was neat and sweet to watch lol. I may have watched it a few times. If my understanding of how they work is correct the arc was being sent through the arc chute, as intended.

Plus that 100W comes out of inverter efficiency when power is being generated.
So let’s say you consider 90% efficiency acceptable when you are generating 1kW - the incremental power being consumed by the inverter beyond the 100W loss you consider acceptable is likely a fraction of 100W…

It all started back at the end of 2020 when my Dad and Brother got me 200w of panels, a 1500w inverter and an MPPT SCC for Christmas. I added ~500wh of lifepo4 then built a ~5.5kwh battery... It's been upgrade after upgrade ever since.Wow, Dude!
The addiction is really real ?. Wow what a blast from the past looking back at those photos.

Excellent...that's what is great...the ability to expand as you can!
I had a tiny setup for ham radio a while back. ?

Ground mount winter rack is a great idea

It's made a tremendous difference in production so far. It's been eye opening seeing how much angle affects production. I quickly realized I needed a lot more pv last winter along with battery capacity. This has been an invaluable learning exercise for me. Whenever I find ideal land to build my forever home on I'll have ESE, S and W facing arrays between roof and ground mounts.

Thanks for sharing. I am learning alot from you.
Yes..very important the angles... I used PV watts website to see the best production angle...
Good site...

Indeed it is a great site. PVwatts along with suncalc.org were invaluable in my planning.

That breaker is junk. I doubt it is rated for 500V DC. Was it marked for polarity?So I hooked up my solar to some dc 500v 63amp breakers but when I switch the breakers off it does something strange inside is this normal (yes i know the breaker is upside down)

It's official. I haven't decided how I feel about it not switching to Mwh ?
