Perfect for our off grid camper
Got this to use for our camper. It works even better than we expected! Changes fast and still works pretty decent when it’s overcast. So far we are very happy with this brand. They seem like great durable quality and arnt too big or too heavy which is great for our camper. Easy to install as well. Got it working in less than 30 minutes.

    Great solar panel kit, is currently working well on top of our RV. I bought it knowing that the roof roofing mounts holes didn’t lineup, but I was able to easily just drill through the aluminum on the panel so it was no big deal. Would buy again.

    Wiring instructions under operation heading with warning " do not attach solar harness before battery harness!". I believe such information if critical should be under " installation ". I expected " operation " to involve keypad menu instructions. Luckily no damage occurred to the unit. That aside I was impressed with the quality of product and ease of install. I can't address portability this is a permanent installation charging 3 batteries powering a 12 volt water pump. Works well!

    What a huge disappointment! The solar panels did not have any mounting holes in the panel and the mounting brackets included were NOT what was in the instructions. We ordered two of these kits, same problem with both boxes. The boxes were labeled with one model number, but the instructions had a different model number and the panels themselves had no model numbers listed on them. Returned for a refund and will find a different system from another company. I find ot very hard to believe this system could really have such a high rating for such a poorly packed product.

    Ich freue mich, Ihnen eine positive Rezension über das TP-Solar 100-W-Solarmodul-Kit mit dem wasserdichten 20A-Laderegler zu geben. Dieses Kit bietet eine hervorragende Ladeeffizienz dank der PWM-Technologie und ermöglicht Ihnen die Erweiterung Ihres Systems auf bis zu 400 W bei 12 V oder 800 W bei 24 V.

    Die Abmessungen dieses Solarmoduls betragen 1160 * 515 * 35 mm (45,5 * 20 * 1,37 Zoll) und es wiegt nur 15,84 lbs. Es ist kompakt und leicht, was die Installation und den Transport erleichtert. Mit einer Spannung bei Pmax (Vmp) von 23,1V und einem Strom bei Pmax (Imp) von 4,3A bietet es eine solide Leistung für den Betrieb verschiedener Geräte.

    Ein weiterer Pluspunkt dieses Kits sind die mitgelieferten Montagehalterungen. Es enthält 4-teilige Z-Montagehalterungen sowie 1 Paar V-förmige Montagehalterungen. Diese Halterungen ermöglichen eine sichere und stabile Befestigung des Solarmoduls, egal ob Sie es auf dem Dach Ihres Fahrzeugs oder an einem anderen Ort installieren möchten.

    Das Kit enthält auch ein Paar 16-Fuß-Solarkabel in Rot und Schwarz, die eine praktische Verbindung zwischen dem Solarmodul und dem Laderegler ermöglichen. Diese Kabel sind gut dimensioniert und von hoher Qualität, um einen effizienten Energiefluss sicherzustellen.

    Insgesamt bin ich mit dem TP-Solar 100-W-Solarmodul-Kit sehr zufrieden. Es bietet eine beeindruckende Ladeeffizienz, ist kompakt und leicht, und die mitgelieferten Montagehalterungen und Solarkabel machen die Installation einfach und problemlos. Wenn Sie nach einem zuverlässigen und leistungsstarken Solarmodul-Kit suchen, ist dieses Produkt definitiv eine gute Wahl.
