Description
Eco Energy Charge Controller PWM 3A 24V - S3 24VThe Eco Energy S3 24V Solar Charge Controller is a compact, high performance PWM controller designed for small 24V off grid solar systems. Rated for 3 amps at 24 volts, it features 3 stage PWM charging with float mode and an extremely low 0. 2 mA night time consumption. Fully encapsulated in epoxy potting within a sealed ABS case, it withstands harsh environmental conditions while providing silent, maintenance free operation. With a maximum solar
The Eco Energy S3-24V Solar Charge Controller is a compact, high-performance PWM controller designed for small 24V off-grid solar systems. Rated for 3 amps at 24 volts, it features 3-stage PWM charging with float mode and an extremely low 0.2 mA night-time consumption. Fully encapsulated in epoxy potting within a sealed ABS case, it withstands harsh environmental conditions while providing silent, maintenance-free operation. With a maximum solar input of 50 volts and a -40°C to +50°C operating range, it is ideal for maintaining 24V battery banks in commercial vehicles, telecommunications sites, remote instrumentation, gates, and other off-grid applications. Designed and built in North America.
Key Features & Benefits
3-Stage PWM Charging with Float Mode: Maximizes battery efficiency and longevity through intelligent bulk, absorption, and float charging stages, ensuring optimal charge without overcharging.
24V System Optimization: Specifically designed for 24V battery banks with bulk charge at 28.8V and float charge at 27.2V. Custom configurations available from 10V to 36V.
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.
50V Maximum Solar Input: Accepts up to 50V from solar panels, providing flexibility for panel configuration on 24V systems.
Ultra-Low Power Consumption: Consumes only 0.2 mA at night, 0.6 mA in daytime standby, and 2.5 mA while 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: 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.
