Its easier than that. Run the healthy battery down a bit (maybe 25% or so) the next morning wait til the sun is up good and bright then enable your charge controller/plug panels in point then at the sun. How many amps are you getting at the controller display? The panels should be running flat out. Take your panel wattage divide by 17.5.v = your amps. Are you getting that at the controller? I have Zamp and Renogy panels. They commonly exceed the panel specifications by 10%, but I’m not dropping much voltage over my panel runs ( 4 gauge bus, 8 gauge). I commonly monitor my 680watts of panels that way.. I always know what duty cycle my panels are doing by just knowing my nightly bat voltage and checking amps production.

Unfortunately for me, science was not my interest; so using my multimeter, or recognizing good results vs bad, is always a "wait, wut?" experience. But you got me through it--Good on you! Seems my new Elecaenta 120V panel passed the test with 22 V and 3.8 A. Seems close to what your video said was good numbers. Daytona Beach is blazing hot today, but on the fence of whether to shine or thunderstorm. So that's enough testing today. Thanks again.

A question. You measured the short circuit current Isc as you directly connected the multimeter to the panel terminal. Then why are you referring to the Imp? I was expecting a current around 6A. Don't you think the 5A is low? Or maybe the panel is not the facing the sunlight correctly.

This test shows if the panel is functional... However, the problem with this test is no one ever actually uses the panels with a short circuit or open circuit. The real test is when you have an actual load like a battery that is low with a controller that is rated rated to use enough load to be measured. Alternatively, you may use a power analyzer that would rate the output of the panel accurately.

Isn't the current measurement supposed to be the Isc, i.e., the closed circuit current? The Imp is the max current you would expect from the panel if a load is connected (@ Vmp). If without a load, or just the Amp meter, the voltage drastically drops; shouldn't you read closer to Isc?

This panel can put out close to 100 watts kzitem.infoUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.

@brucelampe6062

The ammeter basically is acting as a piece of thick wire. (We say its a Short circuit or zero Ohms) Since it has to measure current accuratelty, it can't add any resistance (or opposition to current) while measuing flow. Care must be taken to use the portion of the meter for highest possible current (usually 10 amps on el cheapo handheld meters) since there is no fuse there to blow when you create the short when connecting l meter test leads straight to the panel. If you use the milli-amp (mA) meter setup you will blow the internal meter protection fuse and also get a 0 amp reading on the meter display that may cause you to think your panel is bad. This test method is great for panels that dont put out more amps than the meter can handle.

@@brucelampe6062 My 18 dollar el cheapo meter has two fuses and one I blew out at some point in my tests. Not cheap and hard to come by but it was the 700ma fuse. The other fuse is a 10A fuse so the 10A also has a protection fuse, but some meters do not. The best meters to measure real current with are clamp meters as they can measure upwards of 200 amps. I saw a 20 dollar one that could measure up to 400 amps. I really need to get a cheapo clamp meter as it can measure directly AND indirectly over the hot lead (DC or AC).

Depends if you have connected the solar panels in series or parallel. For example: if you would have 2 of those 100W panels connected in series the voltage of both panels will add up to the total voltage, while current will remain at the same value as could be expected for 1 panel by itself. When 2 100W panels are connected in a parallel circuit (instead of in series) the opposite will happen: measured voltage will remain at the 1 panel level, but now the current of both panels will add up to the make total measured current.

It depends on your power needs. The kodiac generator is the equivalent of having a 100 amp hour lithium battery, a 1500 watt pure sine wave inverter , a charge controller, and all sorts of electrical ports for different devices. If you use one of my 20 % off codes (Adventure) or (4seasons) then the Kodiac is cheaper than buying all of those components and installing them. I like that the Kodiac only weighs 20 pounds so I can take mine in any vehicle and camping. A permanent install in your RV will allow you to go bigger if you need to. As for the lithium batteries, you can not attach additional lithium batteries to the kodiac yet. I heard that they are working on a battery that would be compatible with the charge controller of the Kodiac but it is not out yet. I hope that helps. Thank you for watching and happy camping. Jim

When you hook up solar panels you can hook them up either in series or parallel. When hooked in series you add the voltage but the amps stay the same. When hooked in parallel you add up the amps but the voltage stays the same. So, you might accidentally be adding both voltage and amps together. Probably it is best to know two things... What is the voltage and current from just one panel? And, are you hooking them up in series or in parallel?

I believe it's only 10 amps

I am trying to run a 12vdc attic fan that runs at 11 amps, my solar panel is 120v with only 2.0 amps at 18v. im using a buck converter to convert my voltage to 12vdc The fan will run but im only getting 8.4 v to the fan. On the line side of the converter when the fan is running my voltage is same as the load side, 8.4. What is my issue??? Help

I believe you're going to have to have a battery in line in that setup. Are you trying to run the fan off the solar panel alone?

@@danonly55 4-1 lead acid battery in a small attic fan you can really pick up any charge controller on the cheap end and you'll be just fine. You don't want to spend a lot of money on something that's just going to be running a fan. I would go pwm basic charge controller.

I can't seem to test my solar panel, although I am going through the built on solar charger. So as soon as i disconnect my panel from charging the battery the panel either automatically shows the green LED (high current, which in turn stop it from overcharging so i think it stops any flow of current) and or it shuts off completely.. Is there any other way i can test Amps and volts? The only reading i managed to get was 13.6 on volts, but i hadnt realised i had it on 20 on the multimeter so it not sure if i blew the fuse or not as it wont show anything when i put it on 200 now?

Does your panel have diods in the junction box? Cant really understand what you are trying to say. Can you try again? If its a 12 vilt panel, the voltage when not hooked to anything should be around 21 volts.

Isn't watts (volts x amps)? That would be 107w from a 100w panel? 🤔

I just tried it on my 100w panel and got 21 v and 11 amps haha. That's 200w🤷🏻♂️🤷🏻♂️🤷🏻♂️

Hey thanks for the information. I hooked up my 20 white panel. It says it puts out 17.9 V in 1.14 A. The voltage test fine, but when I test amps with a multimeter, it reads .06. That doesn’t sound right. Any thoughts? Thank you

Bryan Seversky I don’t really know what it was. I didn’t change anything, but the next time I put it in good sunlight I got .76 A and 21 V. Still not up to claims. However it did charge my lawnmower battery really well, really fast. So I guess it’s OK

This current measurement is short-circuit current (Isc), not "operating" current (or really current at maximum power point, Imp), so the comparison to specification is wrong. The measured Isc of 5.09 A is well short of the rated Isc of 6.46 A, so the panel is not operating to specification... perhaps because it isn't correctly oriented. "Instructional" videos which give blatantly wrong information are worse than no information at all.

It was laying flat and it was probably cloudy which is probably why the amps were low. There is nothing wrong with the panel. It was brand new. This to see if your panel is operational, not to test if it is running at peak factory specs. This was just a quick and dirty way to find out if the panel was functional if your trouble shooting a small DIY solar system. If you need to get technical for large array setups there are thousands of VERY detailed and technical videos on the subject. Thanks for the comment and happy camping.

Solar panels can be shorted, and in fact the short-circuit current is a normal specification.
