"I'm trying the reverse lighting and running my tank from 6pm to 3am"
The only way that would work is if you had PG&E installed a time of use meter at your house.
I'm running it after 6pm and into the early morning because elecltricity cost 3-4 times more between Noon and 6pm. That's when my tank was on the most and when I was away from home the most and usually when the outside temp is the hottest.
By switching to an evening on, early morning off schedule it's cooler outside, so it's not adding any additional heat to the inside of the house, I'm home to enjoy it more, and per KW hour is 1/4 the price.
