This was added to a electric troll motor battery box. It works wall and keeps the battery charging throughout the day and when not in use. It's not the fastest charge, but over time, it does help keep things going.

I now own two of these and I still can't get the eco-worthy controller to show only LED 1 which indicates a sealed battery. It always shows LED one and two. The directions are confusing or inaccurate. This controller cannot recognize a battery for what it is. Again I have purchased a small MTTP controller that has no trouble whatsoever identifying what my battery is. ___________________ I gave this a five stars because it seemed unfair to ding my review over the fact that the controller that came with it to proved to be unworkable. After 6:00 or 7 readings of the directions I was unable to make the controller recognize and AGM battery. The AGM would go under sealed battery but it kept staying on two lights which meant that it was either a lithium battery or a gel battery. You can't run an AGM battery on anything other than sealed or AGM. For that reason I had to move to a tiny MTTP controller that worked instantly and made it very easy for me to link the battery with the solar panel. I think that it's a very nice system and I'm using it to trickle charge and AGM battery over winter. My plan is to buy another one of these and set it up in the same way to trickle charge over winter a typical sealed battery. Here is something you'll really love. I set this up approximately 24 hours before hurricane Helene hit the mountains of Western North Carolina. The solar panel was set up on a 4x4 post with a 2x4 support that formed a cross. The cord on the panel is very long and makes connection into a outdoor storage cabinet very easy. I then connected some green covered ground wire to a 4 ft piece of rebar next to the 4x4 post. I then stapled the ground wire such that it was not going to pull on the solar panel. The result was very pleasing. It's survived 40 to 60 mile an hour winds. I do hope to figure out why I was unable to program the control panel that came with it.

Economical 25W solar kit. Works good. This is actually an upgrade for a previous chicken coop door. (See picture) Provides 12 VDC for LEDs and timer circuit on the automatic door, also purchased on Amazon. I decided against purchasing the Amazon Seller's upgraded battery charger/controller based on reviews. This unit provides a decent charging to my 12V 10Ah Lithium LiFePO4 battery with no issues (yet). As pictured, the charge controller is a 10A PWM, only has the most basic functionality. Indicators are all LED, but it is useful without detailed information. The battery LEDs are in 25% increments, my battery is 75% full in the picture (3 LEDs on) and charging. I needed the polarity reverser, that was included in the kit for the coop door to function. You can also manually reverse the wiring from the controller front. Solar panel output was 24V dc (under no load), which was great in Washington state weather. The kit was easy to install with basic electronic/solar knowledge and experience being helpful. I also installed two connectors (ordered separately) going in/out of the coop. I think it's an excellent starter kit that makes daily life easier. If the charge controller fails, it should be upgraded based on your power/current needs. Example - 20A PWM with digital display for V/C(I)/P stats. Con: Manual and Amazon details do not match. The info on Amazon is more correct. 1) This is a 25 W monocrystalline not a polycrystalline panel - the manual is wrong. 2) Charge LiFePO4 batteries with Click 1 (my choice) or 3 when setting up the charge controller. Manual incorrectly says to use Click 2, which is for gel batteries. Hence, recommend to upgrade charge controller when given an opportunity. I still need to organize my cables.

Great price for a complete battery charger kit. The instruction is a bit unclear on the battery type selection. But it works fine.

I have a 33ft Trojan and this solar panel keeps my batteries charged. Especially now during the winter and rainy months, I don’t have to worry about my bilge pump running my battery out.

First of all, I decided to buy this product because I used an electric lunch box in my car for several days and my battery started to need a charge. I didn't want to be disconnecting the car battery to charge it, so I saw some very good reviews about this product. It even comes with a USB charger and I thought it would be very useful. To start with, the product doesn't turn on if the battery isn't connected, which is strange because it had almost 18V input that the solar panel sent to it and so my idea that if one day I didn't have a charger for my cell phone I would just put it on the solar panel without needing a battery died. It does charge through the USB port, but in reality it is powered by the battery and not the panel, which causes a discharge in the battery. I did several tests and they didn't last long because instead of charging my battery, it discharged it. I attached photos of the voltage that went down instead of up. My idea was to keep using my electric lunch box to heat my lunch and leave the panel charging all day so that when I finished work I would find the battery maybe not fully charged but with some charge, but it didn't work, I don't know if the product has some defect but it didn't work for me. It should turn on only with the solar panel on sunny days to be able to charge with the USB port without needing a battery and above all charge the battery because it didn't do that it only consumed voltage from the battery to turn on the module.
