PWM Series Solar Charge Controller
User Manual
SAFETY INSTRUCTIONS
- Make sure your battery has enough voltage for the controller to recognize the battery type before first installation.
- The battery cable should be as short as possible to minimize loss.
- The regulator is only suitable for lead acid batteries: OPEN, AGM, GEL it is not suited for nickel metal hydride, lithium ions or other batteries.
- The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator.
PRODUCT FEATURES
- Build-in industrial micro controller.
- Big LCD display,all adjustable parameter.
- Fully 3-stage charge management. 4.Build-in short-circuit protection, open-circuit protection, reverse protection. Over-load protection.
- Dual USB output, the maximum current of 2.5A, to support Apple’s mobile phone charging.
- .Duai misfit Reverse current protection,low heat production.
LCD DISPLAY/KEY
MENU: Switch between different display or to enter/exjt setting by long press. Up :press to increaae value. DOWN:Press to decrease value.
SYSTEM CONNECTION
- connect the battery to the charge regulator-plus and minus.
- Connect the photovoltaic module to the regulator-plus and minus.
- Connect the consumer to the charge regulator-plus and minus.
The reverse order applies when reinstalling! An improper sequence order can damage the controller!
