Good morning sirs. 

I have had a solar system in my home for a few years. Over this time I have replaced most of my devices with ones that can run off of the DC.

Pretty much everything has been replaced except for a few devices I have not quite nailed down a solution for. 

I think the refrigerator is fine just being on the inverter, but I really want to find a solution for my oven. 



I currently have a 120v countertop oven, its a bit bigger than a microwave in size. I will be installing four 300w 12V heating elements into it, while leaving the original electrical intact, so I can run the oven off of either power source. 

the elements are the simple part but I am not sure about controlling it, since I want to maintain some thermostat control. 

Can I use one of picrel to switch 100A on and off or will it explode? 

with this I will install a rocker to switch the built in controls between controlling the 120v side and controlling this solenoid over 12v. 

it seems simple enough to me that it just might work

They make those in many power ratings 

What part number are you looking at?

I would want one oversized by a good margin depending on how long you will be using the oven at any given time

well that one in the pic is 150A continuous, but I cant find a rating for the breaking. 

my concern is if it will hold up to breaking and connecting a 100A resistive load. Or really connecting 100A and breaking probably 140A due to sag. 

I can get bigger ones but I'm not sure if I need to be looking at something entirely different

>have had a solar system in my home

wow, must be a pretty big house! How many planets?

Like 7

Seems like your house would implode due to either various gravitational forces or due to the vacuum, if the immense heat of the star didn't cause a fire

Good morning sirs

Thanks for the info I will monitors this

The other thing you should be aware of is the cycle lifetime. If you’re connecting the thermostat to this contactor, and it has a cycle time of, say, 1 minute, at 100k contacts that’s like 3 months worth of continuous use.



I assume you’re aware you have to run 2 GA wire to this thing, eh? This is like car battery jumper cable thickness, and you’ll still suffer losses.



Good luck to you!

ahh yes, so you're going from solar light to about 12 volt DC, then converting to 120 volt AC, then converting that to heat



sounds incredibly inefficient

no, actually converting the sun into about 20-120vdc at the pv side to 12v at rhe battery side to then heat



More like 350 mcm cable. 2ga might work if it was about a meter from the battery
