HM series 12V 24V Solar Charge Controller with Auto Switch Settable LCD Back Light Display Dual USB
HM series PWM solar charge controller is the one with friendly setting LCD screen and dual USB connectors. It has 7 working mode includes time control and light control mode. And this model now can do 12/24V 10A, 15A, 20A and 30A capacity.
A PWM (Pulse Width Modulated) solar charge controller is the traditional style. They are robust, inexpensive and widely used in solar panel applications. The nominal voltage of the solar array has to match the voltage of the battery bank. For example, a 12 Volt panel must be used with a 12 Volt battery.
The basic formula for sizing one is to take the short circuit current (Isc) of the array and multiply it by 1.25. Be sure that the solar charge controller you select can handle at least that many amps.
Advantages of this HM series:
√Simple visible LCD display shows live parameters of power system, monitor and check system status. √ All the controlling parameters can be reset flexibly to satisfy your different needs. √ 12V 24V auto switch, and automatically break off when the battery is not sufficient to power loads, make sure battery will not drain off. √Integrated multiple protection against overcharge, over discharge, over load, short circuit and reverse polarity, safely protect your battery. √ Temperature compensation function, the controller can automatically adjust the charge parameters of battery by environment temperature to prolong the service life of battery.
