MPPT Solar Laderegler mit LCD und Bluetooth-Funktion von WATTSTUNDE®

Erzeuge Deinen eigenen Strom mit dem fortschrittlichen MPPT Solar Laderegler von WATTSTUNDE® – perfekt für Dein Wohnmobil, Caravan, Boot und jede netzunabhängige Solaranlage!

Der MPPT Solar Laderegler von WATTSTUNDE® ist das zentrale Element jeder Solaranlage und verbindet PV-Module, Verbraucher und Solarbatterie miteinander. Mit der innovativen MPPT-Technologie (Maximum Power Point Tracking) wird die variable Spannung der Solarmodule in eine konstante Spannung umgewandelt, um Deine Batterie effizient und schonend aufzuladen. Selbst bei weniger optimalen Lichtbedingungen bleibt die Energieerzeugung effizient.

Der WLR-BT 20.90 aus der MPPT-Serie besticht durch sein neues LCD-Display, das Dir eine Vielzahl von Informationen und Messwerten anschaulich darstellt. Erhalte genaue Angaben zum Ladestand der Batterie oder zum Laststrom, um jederzeit einen umfassenden Überblick über Deine Solaranlage zu haben. Dies ermöglicht es Dir, Dein System jederzeit zu überprüfen und bei Bedarf Anpassungen vorzunehmen.

Echtzeit-Darstellung der Energieströme und eine Statistikfunktion zur Betrachtung der gesamten Solarerträge machen den Laderegler besonders benutzerfreundlich.

Der Laderegler lädt alle gängigen Batterietypen (Blei-Säure, AGM, Gel, Lithium) schnell und schonend. Der integrierte Unterspannungsschutz verhindert gefährliche Tiefentladungen der Batterie, während die intelligente Lastabschaltung die angeschlossenen Verbraucher bei kritischem Ladezustand des Akkus trennt.

Maximiere Deine Solarerträge mit der smarten MPPT-Technologie des WLR 20.90 von WATTSTUNDE®. Diese Technologie optimiert mehrfach pro Sekunde den Betriebspunkt der Solarmodule und wandelt Spannungsüberschüsse effizient in erhöhten Ladestrom um. Dies führt zu kürzeren Ladezeiten und maximaler Leistungsausbeute – mit bis zu 30 % Mehrertrag im Vergleich zu herkömmlichen PWM-Ladereglern.

Selbst bei ungünstigen Lichtverhältnissen, wie bedecktem Himmel oder diffusem Licht, erzielt der MPPT-Laderegler beachtliche Energieerträge. Die automatische Erkennung der Systemspannung (12 oder 24 V) und ein externer Temperatursensor, der die Ladespannung an die Umgebungstemperatur anpasst, sorgen für eine optimierte Ladeleistung. Überlast- und Überladeschutz sowie Gegenstromschutz für die Solarmodule bieten Deiner Anlage zusätzliche Sicherheit.

Highlight:

Sieh Dir Daten live auf Deinem Smartphone an! Mit einem Bluetooth-fähigen Smartphone kannst Du viele Daten in Echtzeit einsehen. Nutze die kabellose Verbindung, um Deinen Regler einfach einzurichten, zu überwachen und zu aktualisieren – und das alles bequem über Dein Apple- oder Android-Smartphone, Tablet oder andere Geräte.

Almost perfect...upraised logo should be left off
This toy is great for relentless chewers with strong jaws! It would be almost perfect if it didn't have a "K9" logo in raised rubber on it. That is the place that my aggressive chewer shepherd/bulldog mix focuses on and is able to get small chunks off. Without that logo, he would chew the ball more evenly, instead of fixating on that one spot. He loves this ball and has chewed on it for about an hour off & on each of the 11 days he has had it. Although it is very durable so far, the flaw is the upraised logo.

Perfect for High-Drive Dogs & Surprisingly Durable (six month review)
I use this ring ball for structured fetch and tug sessions with my high-drive German Shepherd mix (91 lbs. at 10 mon.), and it’s easily the best toy we’ve added to our routine. What makes it truly exceptional is how it allows my dog to engage in the full canine predatory sequence: • Chase: He locks in visually and bolts after the ring when I throw it. • Grab & Hold: He brings it back, pins it against my leg, and bites down firmly (the toy—not the leg!)—his way of acting out the natural catch-and-control behavior. • Unalive & Tug: We finish with a strong tug session, which satisfies his instinct to grip and shake—basically his version of “making the toy unalive.” • Settle & Chew: Afterward, he relaxes with a chew toy or eats—completing the full physical and mental cycle in a healthy, balanced way. Durability is outstanding—this toy stands up to intense tug sessions with no tearing or damage, even with a 91 lb powerhouse. My senior dog also joins in for double tug play, and it holds up beautifully to that too. I don’t leave this toy down for chewing—it’s not a chew toy. I use it specifically for fetch and tug, then put it away when we’re done. This keeps it exciting and extends its lifespan. My dog has other chew toys he can use freely throughout the day. This isn’t just another fetch toy—when thoughtful it provides a structured, instinct-satisfying experience that’s mentally enriching and physically engaging. If you have a high-drive or working breed, or a dog who thrives on interactive play, this ring ball is 100% worth it.

The best freetoes socks ever
Color: Black, Grey
Love this toeless socks so much! I could wear it all day. Very comfortable! It is just the right thickness which is suitable in summer time or cold weather as well. Most of the toeless socks I have seen have the gel on the heel area and I don't like the feel of it. I'd rather apply lotion on my heel then wear the socks. I have had some issues with the packaging from Amazon and I made the maker of this said socks aware of it. Julia Bebben was very prompt in her response and very helpful. Thank you Julia for your excellent customer service.

great concept, just one tiny annoyance...
Color: Black, Grey
i love that a sock that lets your toes be free is even a thing that exists. i love that this company was started by a young girl, now turned young businesswoman. i have pain in my big toes, so i can't wear close toed anything, but feet get stinky if you wear shoes/slippers all the time without socks. this is a great solution. the only thing i find slightly annoying (not enough to stop using these) is the seam on the bottom of your foot, near the base of the toes. it is a straight line, which is fine on the top of the foot, but i wish the bottom itself curved a bit, to follow the line of the toes. as it is, the seam lands right in the middle if the ball of my feet, so i can feel the seams everytime i take a step. i am constantly pulling the seam toward the toes, to try to keep from feeling it, but then my pinky toe gets caught and balled up on the inside. outside of that slight annoyance, they're comfortable and fit well.
