Description：

This controller is suitable for all kinds of lead-acid batteries (including open, sealed, gel and other batteries).  If you charge a lithium battery, you must be familiar with its battery characteristics, and you must set the charging parameters before you can use it. For example: charge 12V lithium battery, As of output protection setting 9.5V, full protection 12.5V, start charging voltage 11.5V when the battery drops.

PRODUCT FEATURES：

1.The industrial-grade master control chip, AD sampling precision, temperature, level 16 charging current, discharge current, the cumulative output real-time display, screen shows at the same time, be clear at a glance.

2.Automatic focusing MPPT tracking charging, high charging efficiency, non-stop detection during charging, bidirectional focusing tracking.

3.large-screen LCD display, adjustable charging and discharging parameters.     Ultra-wide charge and discharge adjustable, as long as you understand the characteristics of the battery set its corresponding charging parameters, you can charge a battery.When the output is off, the time can be adjusted, which is more convenient (on the market, there is no point adjustment).

4.built-in overheating, overcurrent, short circuit, open circuit protection, reverse connection protection, when the fault is eliminated, the controller automatically recovers, does not damage the device.

5.bidirectional MOS tube anti-backflow circuit, high-power charging mode, ultra-low heat.

SYSTEM CONNECTION：

1.   Connect the battery to the charge regulator-plus and minus.  The controller will automatically detect the battery voltage, the controllerautomatically set the corresponding charging parameters.

2.  Connect the photovoltaic module to the requlator-plus and minus.

3.  Connect the consumer to the charge regulator-plus and minus.

The reverse order applies when deinstalling!  An improper sequence order can damage the controller!

What is Focus MPPT?

1: The traditional MPPT is to improve the charging efficiency by converting the panel high voltage into high current. 10-30% improvement over PWM. For small solar systems, no use is required

2: PWM: Current is drawn from the panel just above the battery voltage. Cheap, slow charging,

3: Focus on MPPT compared with PWM, modify the resistance to copper wire, and avoid the serious decline in efficiency caused by heating.(PWM+MPPT combined technology)
