20A PWM Solar Charge Controller

Features:
Automatic identification for system voltage: 12V/ 24V. PWM mode brings high conversion efficiency.
5 working modes (light control/ light control + time control/ manual mode/ debugging mode/ normal on) meet different requirements.
2 USB outputs provide with 1.2A total current, making it possible to charge devices such as phone, tablet, etc.
LCD screen display, easy-to-use manual switch, and status indicator light make the operations simple and convenient. Check needed information at any time.
An upgraded 3-stage charging algorithm applies an equalizing charge to the battery every 30 days, effectively preventing the battery from sulfuration, thus extending its service life.
PV input voltage range＜55V, which is suitable for various
