The Eco Energy S5 Solar Charge Controller is a compact, reliable PWM controller designed for small 12V off-grid solar systems. Rated for 5 amps at 12 volts, it features 3-stage PWM charging with float mode and an extremely low 0.6 mA battery consumption. Fully encapsulated in epoxy potting and 100% solid state, it withstands harsh environmental conditions while providing silent, maintenance-free operation. With comprehensive protections and a -40°C to +50°C operating range, it is ideal for maintaining 12V battery banks in RVs, boats, cabins, gates, wildlife cameras, and other remote 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.

Ultra-Low 0.6 mA Battery Consumption: Consumes minimal power during operation, preserving battery capacity for your loads and extending system runtime.

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

Comprehensive Protections: Guards against PV and battery short-circuit, reverse polarity, overload, over-temperature, and battery removal for long-term system reliability.

Fully Encapsulated in Epoxy Potting: Completely sealed to protect against moisture, dust, vibration, and corrosion, ensuring reliable operation in harsh outdoor environments.

Extreme Temperature Range: Operates reliably from -40°C to +50°C (-40°F to +120°F), suitable for year-round use in any climate.

100% Solid State Design: No moving parts or mechanical relays to wear out, ensuring silent, maintenance-free operation.

Lithium Battery Compatible (Custom Model): Available with custom programming for lithium battery charging profiles, including low-temperature charging cutoff (no charging below 4°C).

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.

Designed and Built in North America: Engineered and manufactured to high quality standards with local support.

Great leggings!
Special Size: 27.5" Full Length with Pockets, Size: Medium, Color: Black
These are great leggings! They’re my third pair. They are comfortable, lightweight, and fit great. I wouldn’t say they are buttery soft as compared to other leggings that are listed the same texture, however they are soft and smooth. The pockets are a must and are positioned perfectly.

So excited I found these!

Extremely impressed with these leggings! These athletic leggings are absolutely amazing! The material is incredibly soft and feels so comfortable against the skin. The quality is top-notch, with a durable yet flexible fabric that moves perfectly with your body. They are completely squat-proof, which makes them perfect for workouts, and they stay in place without sliding down, no matter how much you move. Some of my more expensive name brand leggings don’t check all the boxes; as these do! These leggings truly combine comfort, quality, and performance—highly recommended! Also- I am 5’3/5’4 and these hit right at my ankle

Fabulous!
Special Size: 19" Capri with Pockets, Size: X-Small, Color: Flamingo Pink
These are AMAZING! Just received my first two pairs ( black and flamingo pink) and I am back ordering more! They are so smooth and soft and feel great! They fit so well-not to restrictive but have strength enough in the Lycra to look amazing (not the thin, flimsy, cheap tights/leggings). I live in the Sunshine State so I can wear these to workout and run indoor or outdoor practically year round. I prefer this shorter length because they are cooler to wear in the 95° heat 100% humidity. So hoping they make these in the green color and the bright blue color that is available in the full length active leggings! These are my new favorite crop active leggings! Please, please, please make more colors! Amazon, these are fabulous quality and style and at this price point, I'd buy every color and pattern available (I just don't do flesh tones).

Super comfortable fabric and launders well.
Special Size: 19" Capri with Pockets, Size: Large, Color: Taupe
Super soft fabric with a nice high waist that does not seem to rolll down when exercising, Yeah! As always I love a good cell phone pocke. After the comfortable fit I also ordered the Slate Blue version. BTW, I have had 2 knee replacements so this below the knee length is a perfect solution for my vanity issues!.
