PWM AC DC Hybrid Solar Charge Controller
AC/DC Hybrid 15A Solar Street Light Charge Controller
Product Description
Features of SR-EH120
1. With an all-new wireless remote control design, a hand-held
device can be used to modify controller parameters and read system
information.
2. Fully-digital and high-precision constant current control
boasting an efficiency of up to 96%.
3. Supports 12 V and 24 V lead-acid batteries and lithium
batteries.
4. Features a DC detection function. If DC available, the system
will automatically switch to DC power supply when the battery
voltage falls to the DC switching point; if DC powers off, the
system will shut off output when the battery reaches the
over-discharge point after continuous discharging.
5. Boasts an adjustable operating current range of 0.15 A from 3.96
A and an adjustment precision of 30 mA.
6. Employs a load triple-stage dimming and morning light design,
with an operating duration adjustable from 0 to 15 hours and a
power settable from 0 to 100%.
7. Data communication adopts a multi-time two-way handshake
protocol and a data compression algorithm, realizing precise and
fast data transmission.
8. True constant current rather than current-limiting control
ensures smooth and stable output current, effectively reducing LED
light attenuation and extending LED service life.
9. A metal case and an IP68 waterproof level enable the device to
operate in various kinds of tough conditions.
10 Adopts an improved charging algorithm to reduce the
vulcanization effect caused by battery over-discharging,
significantly extending the battery's service life.
11. An overheat protection function enables the device to scale
down the load or shut off the load completely when its temperature
exceeds a certain point.
12. A range of protection measures such as battery
reverse-connection protection, LED short-circuit and open-circuit
protection, etc., put the system under comprehensive and constant
guard.
