do a video of charging a lifepo battery below freezing

show how much below freezing or how high of current you need to go for it to damage the cells

I made that one at some point - you can't even get a decent current with normal charge parameters. The cold increases the internal resistance, which in turn prevents much current from flowing. The capacity test afterwards shows no issues. That doesn't mean you can't force it with higher voltages, but you normally don't see that since your charge parameters are set.
 
We need one about EMP hardening.
Also, maybe one about preventing electromagnetic interference in solar systems.

Maybe do an ALL LED episode?
Showing how easy it would be to wire up your whole house with power sipping LEDS.
Not just replacing your standard E26 incadescents (who even still uses them anayways?) but setting up a dedicated DC house system for high efficiency lighting.

if LEDs are done, i would like to see some parallel/series combos of 12 VDC strings used with different battery voltages [eg 12, 24 or 48]
 
The fact Will is looking for new ideas for content goes to show how over saturated the solar market has become. Every topic and use case has been well covered by Will and others on the Internet.
 
Test remaining capacity of oldest LFP batteries you have to see their true degradation rate. Use Victron smart shunt because it's pretty accurate and measures energy and not only amp-hours.
 
Do a video of videos…

I watch some of your stuff- but I have missed LOTS over the years.

So a Video that says here’s my best one on planning - here’s my best one one crimping - here’s what you need to know about wiring- pre-charge-… all in one video with the links going back to your oldie but goodie videos.

Also do a good one video on troubleshooting issues.

Don't agree at all. He's looking to do content that his audience wants. There is a lot of content out there that is done half ass or is biased or just plain wrong.
 
Tl;Dr

1) Double conversion system for clean power and 0 transfer time. Grid only charges battery. Power supplied by inverter. Pv on charging inverter can export excess pv. Pv on power inverter may be more efficient, but can't export. Any issues with the battery.

2) AC PV input into sol-ark 15k and eg4 18kpv. Does each work as expected? How well does enphase integrate? Other cheap inverters to convert pv to ac.

3) review load shedding options.

4) advanced discussion on paralleling SA 15k or EG4 18kpv. Splitting 200 amp grid input to both inverters, and combining output to power main panel.
 
One of the videos I've been looking for is the software and equipment setup you use to test batteries for their real capacity. I know you hook up some sort of device and use some sort of software on the computer and show us graphs when you get done but I would like to know the setup and equipment used to do that on my own batteries.
Thanks.

Ryobi & dewalt both have bidirectional usb-c PD chargers now I would like to see solar recharging of those since lots of us have batteries already.

I'm guessing this would be all about flexibility, but interested what a price per watt would work out to here over the lifespan of a tool battery. Also would like to find out about equipment durability as my Ryobi DC charger found and early grave...

People in cold environments who realize the incandescent "inefficiencies" show up as radiated heat and retain them in the house envelope so they end up being more affordable, less carbon intensive, and usually more pleasant in ambience than newer subsidized solutions.
 
a teardown of a the weize 100ah self heating battery.
What's the build quality look like these days? What's the heating element quality? Does it have more temp sensors? Are the temp sensors maximum distance from the heating element?
 
An automated means on how to protect Lead Acid batteries (no on-board BMS) from deep discharge. ie: Inverters that only shutdown at 9.5V. Thanks

He did this, but unfortunately, I can't find the video. A very common method is to use a Victron Battery Protect (BP) or similar product to trip the inverter's power switch:

Again, you're tripping the inverter's power switch meaning, you've wired the BP into the switch circuit. Alternatively many lower end inverter include a remote terminal where simply opening or closing the circuit causes the inverter to shut down.

The best solution is to use quality hardware that enables you to set the cut-off point yourself.
