Hey y'all long time viewer of Will's YT channel, finally joining in on the forums.
I bought a new house and I'm getting a grid-tie system. It's being engineered right now and then it will move to permitting with the city. This system is by projectsolar.io and I'll be installing it myself. The system will be 23 CanadianSolar CS3N-395 panels with Enphase IQ8+ microinverters.
I have a Tesla Model Y P as my primary vehicle and would love to shed the solar load for charging at night. I would say my average charge every night is 20-25kwh.
But here's the problem. I have 15kwh of 48v (14s) scooter batteries I snagged from Jag35 a couple months ago for ~$1400. I would love to put these batteries to use.
My power utility provider (Rocky Mountain Power) buys my net metering solar at 5.160¢/kWh and my usage is tiered at 9.0279¢ per kWh first 400 kWh, 11.7210¢ per kWh all additional kWh. Winter is credited at 4.462¢ per kWh and my usage is 7.9893¢ per kWh first 400 kWh, 10.3725¢ per kWh all additional kWh. Sadly they don't offer any good time of use plans.
Anyways, I'd like to put those batteries to use when charging my car every night. With 15kwh, at 6¢/kwh difference, that's a monthly savings of ~$30 for any powerI can store locally and not buy back at night. I'm averaging about 1200kwh/month of total power usage.
What do you guys think the best most economical solution for me would be?
Here's an overview of my power in my house and how it's laid out.
