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.
