SUNER POWER 20 Watts Mono Crystalline 12V Solar Panel Kits - Waterproof 20W Solar Panel + Upgraded 10A Solar Charge Controller + 3-PCS SAE Cable Adapters for Car RV Marine Boat Trailer Off Grid System

It is 81 amp) with light and On July 1, I connected this to the system It was 90 degrees with barely a cloud in the sky. Consequently, it gave rise to The result of 81 A multiplied by 20 V is There is a 2 Watt drain. In fairness, I never expected an affordable solar panel on Amazon to provide a power output equal to 100% of what I expected. As a result, I'm not complaining, and I'm very pleased with it. This is why the stars were awarded. I've set this up in 5 seconds and it's pretty easy - it'll work in a flash I present evidence. In order to mess with the light output, make it 120 (and keep in mind that it is There are many things I can do with this for car camping (I wouldn't call it glamping, but others may There is a heavy canvas tent that I have, and this would be easy to put on the roof or hang from a corner, if it were not windy out. Those panels were too heavy to ensure net zero consumption, and I needed 30 Watts instead. Alternatively, you can look up any SAE cable extension to obtain the length you need. It allows me to position the solar anywhere in camp, 20 feet away from my tent, so I can position it wherever I want. You will only get a few hours of maximum solar, overcast skies the panel is not moved as the sun moves, then you have angular issues.
I figure 1/4 of the time the panel is at number would be lower in winter, but I don't camp in winter. *)* Or, use 62 on average. You should try to cover 5% of the solar panel's output when you are trying to determine if you are able to do so. There are 121 solar panels on this solar panel. The power consumption is 5 Watts I have calculated how many hours it takes on a summer day that lasts 12 hours. '
[I run a fan out of my battery on cloudy/rainy days, so I don't get as much solar power, but The needs you have might be similar to mine. Ensure that you allow for clouds if the forecast doesn't look promising!

[EDIT - EDITED] There was a mistake in the cable length of the panel. It has now been extended It could lead to a loss of efficiency in that case. Compared to the 5 Watt panel I measured below, it is much smaller. ]* This 5 Watt trickle charger (that does not require a controller) output 4 amps x 20 volts) along with the sunriser. This is what it lists as the output, so haze or clouds cannot be the cause. [I recommend the Suner again, as I like.

I got the panel, put a meter on it but did not receive any response. A voltage of 87 volts is needed. There was a yellow light on the controller (no explanation in the minimal paper work why this was happening). The controller was only able to output four volts. A 3 volt battery! As a result of being connected to a battery to charge, the I have sent multiple emails to the company (no phone number! Amazon has been notified that the item was returned. I received a refund from Amazon the day UPS received my package, which is fantastic, although the money was placed in an Amazon 'gift card' rather than being refunded to my credit card.

Edit This page was generated on 12/7/2019 032105. After the return was completed, I received an email from the company. A genuine desire to correct the situation was evident. A 20 watt panel/controller kit was sent (free of charge) and I was asked whether I would like to reinstall it I am reviewing. In my opinion, it made sense. Yesterday, the kit was delivered. Setting it up temporarily was a challenge, as I had to be extra careful to follow instructions. However, they were not written by Americans, so the translator lost some of the original meaning. It was a little low, 12v, so I used a spare battery. A 6V battery. The controller was attached to the battery FIRST, and then the panel was attached to the controller as instructed. The voltage at the battery has been rechecked and it has been 12 volts. The battery voltage is 73 volts, which means it's It was at 11 a. m. It was 30AM with a low winter sun (sun low on the horizon, panel vertical, and not in a good position). This works, then. Further voltage rise is needed, and a re-check will be performed tomorrow and the following An ideal reading should be in the range of 13V to indicate a full battery on Additionally, I will look for a significant drop in battery voltage following a cloudy day (the blocking diodes should prevent this). In order to charge a device like my tractor, I would have to remove the panel from the controller and then remove the tractor from the controller as well. I'm not sure how convenient that is. As long as you are careful (read being responsible) to not short the output you could leave it constantly connected to the controller. The first panel kit failed to light up as only one LED was lit and it was a faint yellow color. I suspect the controller was bad in that case. There is no longer any dimming of the LEDs. Four stars is the result of my rating being changed from one I will give RUB another star if we hit 13V after a full day of sun and don't see a drop in voltage after a cloudy day!
Edit 2 sunder was disappointed when he couldn't write a better review and Mason (his company) was committed to your success. As it turns out, the controller I received was damaged, but the replacement worked perfectly. An issue in technical writing from China to the US is the paperwork with the panel is not clear. A response to an email sent at night may be sent while you are still sleeping, so it can take a long time to resolve any issues. But I can assure you, they are dedicated to taking It takes patience. The battery in my phone is now fully charged Seven volts float) in mediocre sunlight. This is the key to understanding the It is necessary for the battery to be slightly It should be 5 volts or above (any less is effectively dead). First, you must connect the battery. This allows the controller to ascertain the voltage of the battery It takes a few seconds (two lights will come on) for the lights to change and you are ready to connect. Once all three lights have been turned on, they will come on simultaneously. The business is up and running! When disconnecting a battery (such as I do, this is keeping a tractor running smoothly), you must follow these instructions. A disconnect has occurred between a controller and everything. When the battery is connected, the two lights will pop up. Next, connect the panel and all three will be lit. The five stars go to Suner!.

A really great way to keep 2 marine batteries charged at any given.

For my kids' 12V ride on cars, I bought this solar kit to go on my shed so they can charge two small 12V batteries. My solar charger was wired to use an SAE connection so that I could use them in the garage (worked perfectly for 2 years) or use the car charger outside so I could get them out of the As part of my routine yesterday, I switched the charging cable from one vehicle to another to ensure both of them Then, when my 5 year old went out to ride in the morning, he found both of them In fact, both batteries were bulging and ready to burst, due to the overcharging that caused everything to short out and melt. Amazon gave me a credit for the panel, but I'm still out the 2 batteries and all the cables and connectors. It is a great pleasure for me to have a shed with gasoline and power equipment in it. A very bad outcome could have resulted from this. I'll edit this since it changes the wording

Upon request, Suner issued me a credit for the amount I have spent so far trying to repair the ride-ons. Until I receive new batteries to check whether the motors got fried too, I will not be able to find out if they are faulty. Once I have more information, I will update you. The customer service at this company has been very nice and while they do not advertise a 24/7 customer service phone number, they do respond regularly to customer concerns.
