1 INTRODUCTION
The WindyNation Solar Panel Charge Controller provides a reliable charging and power management
solution for solar power battery systems with many of the features that you would expect in a much higher
priced controller. This is made possible by the board microprocessor and embedded intelligent software
control.
The controller features automatic a 12V or 24V DC detect function that will identify the battery voltage upon
initial charge and uses Pulse-Width Modulation (PWM) for automatic charge management and high
efficiency. A built in temperature sensor provides software controlled charge compensation that accurately
adjusts the over-discharge voltage and maximizes your batteries life.
Built in protection includes overload, short circuit, reverse connection, lightning/surge, PV panel reverse
current, over charging, and discharging protection. In the event of a short circuit or overload event, the
system will be protected and remain undamaged.
The enclosure is made of durable plastic with LED lights to provide status indications of charge, battery
status, and system faults as well a user selectable Work Mode/timing interval that will power various DC
powered systems for specified time intervals after dusk such as night/street lighting.
Please read this manual carefully before installing or using the controller and keep it for future reference.
1.1 FEATURES
Compact size is easy to mount on wall or panel.
Charge controller maintains batteries and extends battery life.
Auto sensing for 12 or 24V systems
Built-in battery test function
Convenient screw terminals for wiring
Separate connections for PV panel, battery, and load
Built-in overload and short circuit protection
Automatic self-recovery after fault removal
LED system status indicators
Requires no adjustments
User selectable on, off, and time modes
Wide operating temperature range -35˚C to +55˚C (-31˚F to +131˚F)
1.2 SYSTEM DIAGRAM
The MCU controller takes sample measurements from the storage battery voltage, discharge current, and
ambient temperature to calculate and control the discharge rate.

1.3 SAFETY INFORMATION
Please read the installation and operating instructions carefully prior to use. Pay special attention to the
IMPORTANT and WARNING statements in the manual.
WARNING:
Never install during a lightning storm or where unsafe voltages are present.
Solar panels produce power when exposed to light. Use caution when handling copper wiring.
Do not use with equipment that exceeds the rated power for this device.

2 INSTALLATION
Insure all terminating connections are clean and tight to prevent arcing and overheating.
The controller must be installed in an area that satisfies all of the following conditions:
1. Dry: Avoid any location where water can contact the controller
2. Cool: Ambient air temperature between 30°F and 105°F (0°C and 40°C)
3. Ventilated: Allow at least 2 in (50 mm) of clearance above and below and at least 1 in (25 mm)
on each side for proper air flow.
2.1 ELECTROSTATIC (ESD) PRECAUTIONS
All electronic circuits may be damaged by static electricity. To minimize the likelihood of electrostatic
damage, discharge yourself by touching an electrical ground (e.g.: copper pipe) prior to handling the unit and
