See Will's "12v solar charge controller buyer's guide" for starters: You'll need to understand the basics first. :) My advice below is based on results in Michigan, or roughly 43 degrees latitude. When a panel says it's rated at "100watts" that means it will output 100 watts in lab...

The high self-discharge rate of a super cap is why we don't use them as batteries. That would would be great if we had a super cap that would only self-discharge 10% per week, but it would likely be much more expensive than any battery on the market anyway. Supercaps can be fun to work with...

Price is down to $1516 today. Since these are 60 volt, do I need to give them 60 vdc to charge them? I don't have PV panels to do that high a voltage.

But it's wireless! Lol. I saw these "wireless" static straps on Ebay. :)

I would have used a thermal switch that closes at 80-90F but those are hard to find at that rating. But they are really cheap.

I got a new roof around 2017. If I install solar panels myself, without using an authorized installer, that will void my 30 year roof warranty. Also check local building codes for issues. There are some really crazy local codes, like you cannot collect rain water in some US states. But if a city...

Justin, I went to your ebay store listed in your sig. But in your Ebay store I don't see a category for "open box" stuff. Can you add a category for open box? Thanks.

I'm not sure I understand your question. If you want to slow down your discharge rate, you have to turn off devices that use power. A step-down convertor merely reduces volts and increases amps, and you use some power (watts) in the process due to inefficiency of the step-down circuit. Power in...

And more ideas on Pinterest: =pool%7Ctyped&term_meta[]=noodle%7Ctyped&term_meta[]=uses%7Ctyped']https://www.pinterest.com/search/pins/?q=pool noodle uses&rs=typed&term_meta[]=pool|typed&term_meta[]=noodle|typed&term_meta[]=uses|typed I get mine at Dollar Tree. But it's a seasonal item.

Labor on house stuff will typically add 80-100% to your cost so the price sounds about right for Hawaii, where everything is much more expensive anyway.

45C is 113F. Probably too hot for a battery.

I have the Harbor Freight Thunderbolt panels with charge controller and a 12v lead acid battery. I got this device to measure the amps, volts and amp hours coming in to the charge controller but I am still unsure how to wire it to my system, even after doing some Google searches for diagrams...
