SOLPERK30W 24V Solar Panel Kit, Solar Battery Trickle Charger Maintainer + Adjustable Mount Bracket for Automotive Motorcycle Boat Marine RV

I work remotely, I have a 4-battery inverter, each battery is 6 volts. I have them connected in series for a 24V inverter. Lately, the electrical system in my third-world country has been failing a lot, and there are prolonged power outages. I decided to buy this product because it would allow the batteries to charge during the day. Indeed, it works wonderfully. While there is no electricity from the service provider, with the radiant Caribbean sun, I can use the energy from the batteries while they are being charged by the sun. This allows my inverter to provide me with more power while I keep my office running and the batteries charge while my office is off. Similarly, it helps with the electricity bill since I have disabled the inverter charger, so my batteries will always be charging during the day. I have a voltmeter to monitor the battery charge in case of an electrical storm or long periods of shade, and then I can enable the electric charger. But this solar system works wonders for me.Oh! I almost forgot to mention that, while the inverter is not active, the measured voltage of the batteries while they receive sunlight is approximately 26.0V, and while there is no electricity and the office is running, the measured voltage is approximately 24.9V. This means that the batteries maintain their charge for a longer time while being used.Thank you very much, I am happy with the product, it works well.

I bought two of these to put on some equipment that sits for months at a time to keep the batteries charged up. They came packaged well, are easy to set up and connect. I’ve only been using them for a week but they seem to be working good so far. I’ll have a better idea in a few months when I go to start the machine.

Given the appalling lack of a mounting bracket, I assume that we were supposed to use the mounting hardware in conjunction with separately purchased two sided tape, and perhaps hopes and dreams to hold the panel in place.

I'm still warming up to solar solutions but I needed a 24 volt battery tender for my 500 hp diesel snowcat. Parked in the snow all winter with no source of electricity, my only solution was solar. I bought this hoping it would work and it has exceeded all of my expectations. Reliable. Durable. Effective. Worth every penny. This summer, I've built a pole barn for the snowcat and have dedicated power to the barn so I'll be plugging something in, now, to tend my batteries but I'll miss using this! I'll have to find something else to use it for. Great product.

I would’ve given a zero rating. 28 days with 8 hours of pure sun while constantly adjusting the panel to the suns ever-changing angle would charge my 200 AH battery (without using it). Optimum output gives you a measly .875 amp charge max, phone chargers operate around 2 amps! To get optimum output, you have to readjust the panel to the sun every half hour or so. I cannot imagine what the ecological amortization is for this heavy, steel panel. AND you still have to buy a charge controller to use it.This product is a joke.

Having 24v machines sit for long periods without starting is a battery drain. With this device, at 25volts the trickle charger goes into hibernation. ordered one set for a trial, then ordered a couple more. Game Changer, thx.

good parts

I have my Pontoon in open storage waiting for covered with electricity. I am allowed to use an unoccupied bay to charge but...I am asked not to leave in case the real occupant returns.I bought this 50-watt 24v capable panel as a cure-all for sitting there for 3-5 hours twice a week. It works but as I use my boat up to 4 times per week. The panel doesn't keep up. I have to occasionally assist it by non-solar charging. I wish it could do better but!Tips: Best aimed due East. Do NOT block any part of the panel. The instructions are a nightmare to fully understand. Light from Left to Right. Left light shows proper connection to panel & is fully on when connection is proper, and the panel is charging. In correct hookup or panel areas blocked it flashes Red. Not charging or fully charged light is out. Middle light is off, generally the case. Green indicates fully charged. Right light or Load Green most of the time. For Tolling motors in General: Charging from left to right, Red, Off-clear, Green. Fully charged Left to right 'Red, Green, Green'. Ok, not sure I made this any easier. Final comment. If your boat is used only on weekends this should be great.

I have tried a few different battery charging systems over the years and gotta say this is my favorite.

Working well if is sunny, if is clouds no power at all. So winter time is not good

Troling motor

I plugged the solar panel into the controller then I plugged the controller into the cigarette lighter.. which functions when the ignition is off.. no lights light up 🤔.Is the solar panel working or not?
