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.

Malinois proof
Color: B) Medium 3" Ball
So far this has held up great. My Malinois who has destroyed nearly every ball I’ve gotten her, this one has lasted over 3 weeks without a dent, compared to some that don’t even last a day lol. Although the medium size is a little too big for her liking she still plays with it. It’s very durable and I like the middle part for engagement as well. I would recommend if you have a dog who destroys every ball possible.

Actually Durable
Color: B) Medium 3" Ball
One of the few "heavy duty" toys that my pittie hasn't destroyed after a couple of weeks. Most of them last two days. She's an absolute beast so I'm confident if she can't destroy it, few dogs can.

Color: H) Infinity Ring, Color: H) Infinity Ring
Not for aggressive chewers! Done for in about two minutes. I unboxed this and tugged with my Mal for a but then let her have it. Within minutes she had chewed through it. Not worth the money.
