Features
Details from the HilapriSol 20APWMSAE01 Amazon listing:
- Durable 20A PWM controller + 1 Extra SAE Cable：Solar charge controller 12v features a simple and stable circuit for better cost efficiency. Less components mean fewer breakdowns and low standby power waste, supporting reliable energy flow between solar panels and batteries. Increased output current cuts charging time for your 12V off-grid setup. Solar charge controller is compatible with max 300W solar panels with no integrated charge controller. Not suitable for 24V or 36V battery banks
- Ultra-Low Standby Drain & Reverse Current Protection: charge controller 12v uses optimized circuitry draws barely any battery power on standby.Charge controller features a built-in blocking diode inhibits reverse current drain post-sunset to avoid wasted energy and maintain battery capacity overnight
- Comprehensive Safety Protection: The charge controllers for solar panels come with built-in safeguards for overcharging, overvoltage, overload, short circuit, reverse polarity and overheating. Solar controller features intelligent 4-stage charging that automatically adjusts modes according to battery conditions to avoid damage, prolong battery life and deliver reliable, safe performance for your full solar setup
- LCD Real-Time Monitoring: Solar charge controller 12v is equipped with a high-definition LCD display and LED indicator lights. Solar panel controller lets you check solar voltage, battery voltage and charging progress in real time. Simply press the button to view real-time current, and the screen automatically switches to power-saving display mode
- Authoritative Certification & Professional After-Sales Support: Solar panel controller is certifiead to FCC-SDOC, CE, and UKCA standards for verified safety, stable performance, and full international compliance. Our customer support team assists with all your installation, setup, and usage concerns, delivering reliable and worry-free after-sales service
