You need at least 13 volt to force any charge into a lead acid battery. If this solar thingy does not have a reverse current protection circuit it is going to discharge your battery if it does not get enough sunlight to push charge into the battery. This device does not have the power capability to charge a car sized battery.

This panel can put out close to 100 watts kzbin.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.

I have one of these panels, and in my driveway it puts out 19.5 to 20 VDC on a sunny August day. I tilted it to the South at about 45 degrees. I am in the Sierra Nevada at about 1200 ft elevation on the 38th parallel. If I decide to try to use it as a 12 V battery charger, I will install it with a solar charge controller to limit the voltage output to avoid damaging my batteries by boiling out the electrolyte.

I thought I would just throw my two cents in on this conversation. I think this charger works great. I had a guy who was working on my truck for a year and every time I go over the battery would be dead and we have to jump it or charge the battery. It was a brand new interstate battery and the truck has an internal drain somewhere. I don’t drive this truck very often so I threw one of these Harbor Freight maintainers on the dash and Hooked it up through my cigarette lighter. It hasn’t been driven in five months but when I go and start it up it’s got full energy on the battery. If anything it might be overcharging it a little bit. No I haven’t tested the battery or tested the energy coming out of it but when I start the car and the starter is spinning at an extremely high rpm I know the battery is fully charged. My only gripe is it’s got two suction cups that you can stick on the glass windshield and they suck. It eventually falls off after two or three weeks. But I leave it on the dash and it works fine. I went and started the truck two days ago there was no direct sunlight just reflections and it has a little blue indicator light when there’s power going through it and it was blinking. So I can give it five stars.

All of the voltage measurements of the battery were taken with the panel attached, so you were reading the voltages of the panel and battery combined. A real test would be to take the panel off, then measure resting voltage, which should be at or above 12.6v. The 100w kit will get you there much faster, then you can use this little panel to keep it topped.

I've been using a similar model of panel to this (no LED) in Australia for a few years. They definitely work. If you don't drive everyday, then they are very handy. I had to get the cigarette lighter changed to 'live' so that I could use that to charge with rather than the battery terminals. I originally mounted mine inside the rear window as I parked on the street, but now it's been outside next to the garage for 2 years. I bought an extension lead from eBay for a few dollars to reach outside the garage. Due to the colder climate in my new place and not being able to mount in the best position it hasn't worked as well. The car battery was bought new in Nov 2013 (nearly 8 years old), previously I was only getting 2.5-3 years tops. I bought an AC trickle charge recently and they are very handy too. If you test your battery after a few cold winter days and find the volts are 11.8-12.0 (and you can't start), then 2 minutes with the trickle charger and it's good to go. There's a also a repair mode that removes some of the buildup in the battery which improves the charging. If you live in a cloudy, cold climate in winter, and/or you can't mount it in the best position, I would recommended getting a higher capacity panel than the 1.5 Watt of this one. But otherwise, they do a good job of preventing flat batteries.

My buddy came and picked me up and we went to Harbor Freight, bought one I came back and put it on the dash, plugging it in to the dash power source. No jumping the battery, I just wanted to see what it could do. In 3 hours my truck started right up like it had a full battery. I have since bought 8 more as gifts to my family and church member friends so they don't get stranded anywhere. It works in lower light it cloudy days but at only about 30% to 50% of what direct sunlight does. I suppose your "back and forth" probably has to do with the fact that it's made in China by unskilled laborers and sometimes substandard materials.

Couple things to remember when using a trickle charger the charger you used only supplies 1.5 watts if the car is draining more than 1.5 watts then you will not charge the battery just slow down the discharge of it, also these chargers seldom hit their quoted wattages so a 1.5 watt may only deliver 1.2 watts or less, also with the cigarette lighter most newer vehicles have auto disconnect of the cigarette lighter after about 15 minutes so any charge going into them is wasted, might be the reason for the high number of people that say they don't work

Not saying that these don't work (I just bought two), I just think an overcast day will not allow them to perform at the full 1.5A potential, not even close. I plan to do an amperage test during an overcast Florida day, and then compare this to results from a blistering Florida day. I have hope they work, but not much hope that these will maintain four deep-cycle boat batteries. I hope I'm wrong.

So it works for me only fully sunny days, how ever note this is a charger to maintain capacity really & not charge, only hot countries may benefit to charge fully small bike batteries ...

Recently, I've seen a YubTub ad about them that they're "On Sale" for $75 plus shipping. Holy Molé. That's 4 times what I paid for mine here in Mexico. They work well, for the most part, but we had a bad run of them, and 2 of the last 3 would not hold a charge and Coppell did allow us to exchange them. So I'm holding off buying any more until they fix the problem.

They are mostly a battery maintainer (ie) as vehicle that is in Storage. I just put mine on the dash board for the winter and it keeps the battery up all the winter.

It is a fact that this will NOT even maintain a battery on a vehicle. Vehicles do have some parasitic drains to keep the clock and ECU powered. I had one of these on vehicle that I only moved across the streed twice a week and this did absolutely nothing to help it. The current is just simply too low to even keep the battery charged. The battery was low and It was fully charged my a charger and ran for years after. This is a waste of money. I didn't cut the blue LED so I don't know if that would have helped but it didn't work.

If you started you car twice a week, which uses a fair amount of battery power, but didnt drive it long enough to regain that power through your alternator; then you used up what little charge the solar panel had generated just to keep your battery's level where it's at - so its like not having a charger at all therefore your battery just kept getting lower and lower. Without the charger it would probably go flat quicker especially with the starting twice a week.

If you know which circuit is causing the drain, you can remove the fuse for that circuit when not in use. If it powers equipment with memory, it probably wouldn't be a good idea. I has a drain problem which sometimes could kill the battery in as little as 2 hours.
@patrickweaver11055 жыл бұрын
Under ideal conditions it will produce 1/8 amp. That will keep a fully charged battery maintained but it will take over a month to recharge that deep cycle battery. A 12 watt solar charger is about the minimum I would use to top it off between infrequent uses.

The LED is not in series with the charging circuit so it does NOT have anything to do with the charge control. It is only there as a pilot light to indicate that you are getting some light to generate some power. It is actually robbing charging current from the charging circuit so when it is cut out the current wasted to light the LED is going to charge your battery instead.

Little things that may improve detergent the LED light disconnected and uses power that will boost your milliamps a little. Number two solar panels put current into a battery. But when the charging gets too low oh, and a current will reverse and go to the solar panel. At act like the little red diode draining the battery. So disconnecting the battery at night would prevent that. Do a little research and you'll see that solar panels are diodes any M Image a low-level light that you cannot see, which causes a drain.peracetic

There is no way this thing can charge a battery. If it puts out 1.5 watts at say 13.6 volt minimum if there is enough sunlight (13.6 volts is recommended float voltage to maintain a lead battery). You need at least 13 volts to push enough current into a battery to provide any charging current. This would mean that 1.5 watts divided by 13.6 volts is 110 milliamps of current. Per the box that is "peak" output. During extremely bright days this thing might be able to maintain a fully charged battery. It does not have enough power to charge a battery. Anything under 12. 8 volts output will discharge the battery instead of maintaining it if this device does not have reverse current protection built into it. Don't waste your money on this thing.

Inside is a diode too for protection, i looked inside my panel. The blue led is in parallel. In a sunny day, oriented perpendicularly to sun, will give about 90 mA. Is very low but will keep battery charged and, over time, a very low charge 90 mA x 11 sunny hours = ~ 1 A.
@jp0407595 жыл бұрын
@@chitibusu Here's the math. Most 27M size batteries are 90 Amp Hour capacity. Let's say you discharged the battery by 20 amp hours of capacity. At 20 amp hours divided by .090 (90 milliamps) amps per hour from the solar panel assuming optimum sunlight conditions it will take 223 hours of bright sunlight. Assuming 11 hours a day charging light it will take 23 days assuming you have 23 days of super bright cloud free, haze free sunlight. Let's assume 50% of the days are super bright, it will take 46 days to charge the battery and that is from a 22% discharged battery. It is very unlikely that you will have anything close to constant 90 milliamps of current available for that long in any one day. This does not even take into account the charge efficiency of a lead acid car battery which is 70%. What this means is if you have a 100 amp hour battery, it takes 143 amp hours of current going into it to get the 100 amp hours of capacity out of the battery. 43 amp hours of energy is going into changing the chemistry of the battery back to power generating chemical combination. So again! There is NO way this thing is going to charge a car sized lead acid battery. Don't waste your money on this thing. I would recommend at least a 15.0 watt solar panel to have a good stiff trickle charge capability. OR get 10 of these 1.5 watters and wire them in parallel..
