SRNE Solar Panel Regulator Charge Controller 12V 24V 20A 3 Stage
PWM Charging
SRNE PWM solar charge Controller 12V/24V 20A With one 5V, 1A USB
port
Product Overview
An upgraded 3-stage PWM charging algorithm is adopted. Application
of an equalizing charging to the battery periodically or when over
discharged, can effectively prevent the battery from
non-equalization and sulfuration, thus extending the battery's
service life.
With abundant LCD display content, such as Battery voltage, Battery
capacity, Charge current, Discharge current, Temperature, load mode
and Error code etc.
Designed 5 different working modes for choosing, such as Light
control mode, Light + time control mode, Manual control mode,
debugger mode and Normal on mode. Also there is a 5V, 1A USB port
for mobile phone charging.
Various of protections make SR-HP2420-S more reliable, it widely
apply to portable solar charge box, BIPV system.
Application:
Ideal for off-grid solar lighting system that needs light and timer
control
Solar street light system
Solar garden light system
Solar billboard
Solar detection equipment etc.
