Chris is the master you did a good job😊

Every tool company needs this

Nice. I'm attempting to do the same thing. I have the exact boost converter. I gambled on a knockoff dual port Ryobi 40v charger for $21. It works fine. I have the solar panels. I've watched the SerendipitySue videos. Now I just need to redress the cables. I don't blame you for not demonstrating. I think I'll go with XT60 since it fits my panels either directly or via connecting cables I already own.

Nice work!

Love it will it charge the Milwaukee m18 battery’s ?

Nice

how many ryobi batters can one 100w solar panel charge

Great video and overall idea! I’ve been charging Ryobi 18v, 40v batteries using solar, but had to go thru my Goal Zero Yeti as an interim step. This removes that guy from the picture, freeing it up for other things. This is genius. Thanks for posting it. I look forward to more. Is there a way to hook up multiple chargers to one panel and charge several batteries simultaneously, just more slowly? Thanks for the great video.

Can this sort of method work for 18v batteries too? Would it still need the 24-72v moor or would I need a 12-24v mppt?? Thanks to anyone that can respond and help me figure out something

My solar panel controler as 2 usb plugs built in but they're not usb-c. Do you know if a regular usb plug could charge a 18v battery using the ryobi 150w power source

Is that a different mppt controller in the link or updated version

Hello! I will assume that can charge a 18v Ryobi charger as well right? And it will fully charge the battery as faster as if is connected to the house outlet? Also do you know another link where I can find the solar charge controller? Because the link that you provide in the description the item is not available and if you can provide also where to find the solar panel I will appreciate too.Thanks!

Future

Is that a boost converter for a solar panel.

How do you setup the charge controller? What's the output voltage set to? Thanks for the video! Been wanting a way to do this as well.

Thanks for your videos. My questions: For a most cost-effective off grid charging solution as mentioned at 00:35, could you not simply buy a $20 12v inverter to 110v output and use your car battery to charge up your tool battery with a 110v regular charger? Would a regular Ryobi 110v charger work with a modified sine wave output? A Ryobi 18v 4Ah battery is rated at 72 watts, and the Ryobi 40v 4Ah battery is rated at 144 watts. How much would charging those batteries drain a starter battery on the car? How many Ryobi tool batteries could you charge before you needed to start the car to recharge your car battery? I have the Ryobi P131 in vehicle charger, currently selling for $40-$50, and it plugs directly into the 12v accessory socket of the car. That works great for charging 18v batteries. I don't know if Ryobi makes a 40v in-vehicle charger, but that would be nice. The 100 watt small solar setups seem to cost about $150.00, or more, and they only work if the sun is out. Anyways, your video gets a person thinking. Thanks.

Nice setup for multiple panels, multiple chargers, but since your panel is putting out 22v+, for a single panel, single charger, I don't think you need the converter. Couldn't you just run the panel straight to the charger?

If you're out in the middle of no-where, then i guess it's cost effective but for about $200, couldn't you buy 2 more batteries and not have to spend hours setting this up? Why wouldn't you just put this into an inverter to give you 110v outlets and plug in the charger?

That’s going to be inefficient. You have your dc output from your panels being converted to ac through your inverter which is then converted to dc through the switch mode power supply on your charger. If all you’re doing is charging your Ryobi batteries that is going to work out great but if you’re using that system to charge a battery bank as well you’re losing out on energy you could have stored. A buck converter and a simple bms would accomplish the same without the additional losses.

You keep calling that blue box a charge controller but it seems to me it's really an inverter that converts the DC voltage coming in from the solar panels to AC so it can power the Ryobi charger. Or is it a combo charge controller/ inverter. Hmm?

There's got to be a more simple way anyone could do. Without the extra parts that you have to buy then splice wires.

Can that charge controller be configured for your needed voltage and float? Ideally with what these batteries cost , every power tool battery would have a built in BMS for protection from overcharging.
