    Yesterday my sand battery with the dutch oven, insulated with fiberglass hit over 600 F! This morning the next day the lowest temp it was at was 234 F!

    The temp is going up again, looks like I will have this well over 200 F for over 24 hours!

    This is with 3 solar panels 220 watts each… I have about 1 5 gal bucket of sand in the mix.

    I am now thinking about what if I used an aluminum puck in the dutch oven so that I could pull it out and cook on it……

    These temps are with partially cloudy days, next week they are calling for clear sunny days….

    Now I am thinking of moving forward with building a sand battery the size of a IBC container 250 gal…….

    I would then use the power I am not using after my batteries are charged to dump into that to store heat…..

    The present setup should give me a good idea of how to scale up….
