V3 on Solar + battery only

this looks cool

it has a % thing right on it. neat.

I’ll be interested in seeing how you get it figured out. I had thought about doing that myself with one of my portable solar generators, but ended up just hooking it up to an extension cord that I had already run out to my chicken coop/run.

Keep in mind that most battery banks aren’t designed to be charged while being used.

I’ve found some solar panels with built in batteries that go well beyond the one or two typically found in panels intended for something like a Blink camera, but they still seem to come up short for powering something like a Wyze Cam 24/7. Here is one example:

The 5V output option with 6 batteries is still only 18000mAh (which I expect is just under 67 watt hours).

I also found some that had 8 watt instead of 4 watt panels, but still only six 18650 batteries inside.

Any way you slice you, for a system that would last multiple overcast days, one will be paying considerably more for the panel, charge controller and battery (and probably a weatherproof enclosure for the latter two) than than the Wyze camera, and it will be a rather bulky setup.

Ecoflow solar generators can be used while charging.

Those aren’t your typical power bank of the type the OP linked to. It was nearly pocketable device with a solar panel attached.

They also aren’t well suited to the application (not weatherproof, have an unneeded AC inverter, relatively expensive).

The V3 Draws about 1.12 amps @ 5.1 vdc,i have 1 running on a 60,000 mah power bank it will run over 16 days no issues

Where do you get your information @kae4560 :rofl:

You state a V3 draws 1.12 Amps yet Wyze supplies a 1 Amps power supply?

The most current I have seen a V3 draw is 0.8 A (800ma) and that was with the I.R. On, Spotlight ON, Siren Sounding and Live Video streaming. Otherwise current draw is much less.

At @kae4560 - A 1 Amp current draw on a 60,000 mAh (60 Ah) battery would last 60 hours.

Lets say the averaged current draw from a V3 would be closer to 500 mAh so a 60,000 mAh battery bank would give 120 hours (5 days) - So a battery bank of 60,000 mAh will not give you 16+ days

From my 4 port display usb charger…and yes with the LED Spotlight it will only ad .11 more

Whoosh :exclamation: :airplane: - Look Up…LOL

because I got 99 cameras and a problem not with one :musical_note: :notes: :musical_note: :notes: :rofl:

Several years in an off-grid home experience talking. Use 6 hours of sunshine max, if the solar panels are not tracking the sun. Because you are going to have a panel that is never really perpendicular.

The problem you are going to run into is the battery bank’s maximum charging rate. Say you want 4 days of reserve power in case of a storm. You need 400 WH in the bank. Your output has to be 5V for the camera for highest efficiency, (many power banks offer 5V out) so you need 80AH in the bank.
You’ll want a bank that can charge at higher voltage to match your panels, and you need to pump 400WH into the bank in 6 hours, so a 67 watt panel. At 12V (a common bank charging option) that’s only 5A. Make SURE your battery bank offers “pass through charging” so you can leave the bank charging all the time.

Get a “Jackery 500”, a locking weatherproof box to keep it in, and a weatherproof 100Watt “12V” panel to charge it. Depending on the local weather, that might last all year but a few long storms.

Each camera setup will run you ~$600 but it will work.


FWIW I picked up an iHome usb battery at Goodwill labeled 10,000 mAh @ 3.7v, charged it up, plugged the v3 into it and it ran fine for around 22 hours. At that point the display showed 5%. Not using audio or IR.

You can pretty much throw all your math out the window.

The 20w panel is adequate but your storage idea is lacking. Forget battery banks. They just dont have the capacity and its very difficult to find any that are pass through. You need real batteries and a solar controller to regulate the voltage down to 5vdc and to control the charging. Youll have to match the controller to the type of battery so pick your batteries first. A lot of people (myself included) have used a deep cycle marine battery and others have gone with motorcycle type batteries. I started with four 6vdc batteries and added another pair when I thought that wasnt enough.

As you can see, it isnt cheap. Both my projects were pushing $200 by the time I was done but both have been online for a couple of years and neither ever went dark.

Without knowing distance from nearest wall outlet to end of driveway, have you considered running low voltage landscaping lighting wire. Typically lights maybe run by an 12 vac transformer. The wires are rated for direct burial, but would suggest running thru pvc conduit. Feeding 12vdc would allow for voltage drop, and then a 12vdc -5v dc dc (or 12vac-5vdc) converter. Less parts. Might also put a wireless wyze or other switch on the ac power in case the camera locks up and needs a power cycle. If you really want solar could feed a long wire with the solar, Might be easier to have panels closer to house, and switch to battery or ac power when there’s no solar. Might also need to factor outdoor temperature effect on battery capacity.

I have buried both 12vdc and 120vac lines for various applications so solar would be for when neither of those solutions seemed best for the location. You also have to consider hardscape, established landscaping and distance before you start trenching.

It doesn’t take far before buriable wire, transformers, converters and watertight connectors are more expensive that panels, controllers and batteries.

Missed the comment “no way to realistically get power here” Another issue might be getting reliable wifi signal to the location.

There’s also some skill needed to fabricate a weatherproof remote power supply that will resist whatever the local conditions are. The author did not provide details on damage to yard - if its human vandals or hungry animals that could possibly attack the equipment.

Getting remote power might allow for expansion like flood lights or charger for electric fence

First thing I would get is a $10.99 USB digital multi meter that plugs into your usb power supply and shows voltage and current. This can help you troubleshoot voltage and current problems that seemed to occur with daisy chained v2 cameras. If the voltage is dropping too much the camera will get stuck and can’t power up.

I am getting my toes wet with solar. Bought some cheap stuff off wish.com and frankensteined a flexible solar panel, charge controller, and a 12 volt gel cell battery.

Been sitting in a box waiting for sunnier weather.

Would be nice to have a wireless power monitor that would give status of your power supply other than the v3 camera online or not.

This is what I use, and it needs to be connected in series at the camera. This will check the power cable also.

It is about $30 on Amazon

My previous USB tester

Sells for less than $20 but doesn’t graph like the other does.

As an auto mechanic, I learned current is just as important as voltage. You could have a 12 gauge stranded wire with only one strand and you would read the same voltage at both ends of the wire. Put a load on the wire, the amps kick up, snd the voltage drops. So testing at the source (wall charger) does not check the complete circuit.
