The Eco Energy S3 Solar Charge Controller is a compact, high-performance PWM controller designed for small 12V off-grid solar systems. Featuring 3-stage PWM charging (bulk, absorption, float), automatic night-time shutdown, and temperature compensation, it efficiently manages battery charging while consuming minimal power. Fully encapsulated in epoxy potting within a sealed ABS case, it withstands harsh environmental conditions. With an ultra-low 0.2 mA night-time consumption, it is ideal for maintaining batteries in RVs, boats, cabins, gates, wildlife cameras, and other remote applications. Designed and built in North America.


Key Features & Benefits

3-Stage PWM Charging: Maximizes battery efficiency and longevity through intelligent bulk, absorption, and float charging stages, ensuring optimal charge without overcharging.

Automatic Night-Time Shutdown: Automatically powers down when the sun sets, reducing power consumption to an ultra-low 0.2 mA and preventing battery drain.

Temperature Compensation: Automatically adjusts charge voltages based on ambient temperature, protecting batteries from undercharging in cold weather and overcharging in heat.

Fully Encapsulated in Epoxy Potting: Completely sealed within a rugged ABS case, providing maximum protection against moisture, dust, vibration, and corrosion for reliable outdoor operation.

Ultra-Low Power Consumption: Consumes only 0.2 mA at night, 0.6 mA in daytime standby, and 2.5 mA during charging – preserving battery power for your loads.

Compact and Lightweight: Weighs just 50 grams (2 oz.) with dimensions of 1.5 x 2.75 x 1.3 inches, making it easy to install in tight spaces.

Smart LED Status Indicator: Provides clear visual feedback with three flash patterns: 3 flashes for charging, 2 flashes for bulk voltage achieved, and 1 flash for float mode activated.

Eco-Friendly Manufacturing: Built using solar power, reflecting a commitment to sustainable production.

5-Year Warranty: Backed by a 5-year warranty for long-term peace of mind.

North American Design & Craftsmanship: Engineered and built to high quality standards with local support.

Quality product but sold on Amazon cheaper with different seller.
Size: Medium Size 2, Color: White-Blue
The size is the reason for the missing star. Made of good quality but found cheaper from another buyer. My 9month Cane Corso hasn't destroyed it yet and enjoys playing keep away with the other dogs.

absolutely must buy perfect for dogs. I have a large black lab and he has had so much fun with us.
Size: Large Size 3, Color: White-Blue
I have to say that my dog would be considered an aggressive tower. However, this ball has stayed intact. I love that it comes with the pump. It’s extremely functional very soft for catching can be cleaned. Very easy easy the quality is exceptional. Very functional does have a bounce. I can say he has had so much fun with this since it’s getting it for his birthday on 11/11 I highly recommend this product and would definitely buy again.

I purchased one of these for my pup and he has a ball throwing it up in the air and chasing it. Handy for something they can play with alone.
