Page 8: Installation Steps
1-7 Installation Steps: This section provides a brief overview of how to get started using the SunWide controller. However, please review the entire manual to ensure best performance and years of trouble-free service. NOTES: The SunWide prevents reverse current leakage at night, so a blocking diode is not required in the system. - Page 9 connected during the daytime and the array is wired correctly. ※ If the SOLAR is disconnected during installation, the controller will see this as the first night and the length of night will be too short. This will only affect ON/OFF/ON settings, and will automatically be corrected over 4 days.

Page 10: Operating Modes
2-1 Operating Modes There are three distinct operating modes programmed into each SunWide. Different from SunStar, only one mode of operation being selected for an individual unit, SunWide can be operated at Solar Battery Charging mode and DC Load Control or Lighting control mode at the same time. - Page 11 Four Stages of Solar Charging EQUALIZE ABSORPTION BULK FLOAT CHARGING NIGHT NIGHT TIME Solar Charging Stages 1. Bulk Charging: In this stage, the battery will accept all the current provided by the solar system. 2. PWM Absorption: When the battery reaches the regulation voltage, the PWM begins to hold the voltage constant.
- Page 12 Battery Types: The SunWide’s standard battery charging programs are suitable for a wide range of lead-acid battery types. These standard programs are select by DIP Switch 3~5. Standard Battery Charging Programs The SunWide provides 8 standard battery charging algorithms (programs) that are selected with the DIP switches.
- Page 13 F. Equalization Interval–Equalizations are typically done once a month. Most of the cycles are 28 days so the equalization will begin on the same day of the month. It can be set by Dip Switch 3~5 for different interval days. Each new cycle will be reset as the equalization starts so that a setting day period will be maintained.

- Page 15 Standard Equalization Programs Both automatic and manual equalizations can be performed using the standard charging programs. Manual Equalization The SunWide is shipped with the DIP switch set for manual equalization only. This is to avoid an unexpected or unwanted automatic equalization. In the manual mode, the pushbutton is used to both start or stop a manual equalization.
- Page 16 The battery manufacturer can recommend the specific gravity or voltage values for your particular battery. Float When a battery becomes fully charged, dropping down to the float stage will provide a very low rate of maintenance charging while reducing the heating and gassing of a fully charged battery.

2-3 Adjustability of Load Control When setting in the load control mode, DIP Switch 7 should be placed at OFF. The LVD (low voltage disconnect) and LVR (low voltage reconnect) are important setpoints to protect the system battery from deep discharges that could damage the battery. The Procedure of LVD/LVR Selection Step 1: Press MANUAL EQU/LVR push button and LIGHT TEST push button at the same time until the CHARGE LED turns red and LOAD LED turns green in... - Page 18 • a power diode • rated equal or greater than 80 volts • rated equal or greater than 10 amps (SW-10CL) or 20 amps (SW-20CL) or 30 amps (SW-30CL) For large inductive loads, a heat sink for the diode may be necessary.

Page 21: Troubleshooting
2-5 Troubleshooting The SunWide is very rugged and designed for the most extreme operating conditions. Most PV system problems will be caused by connections, voltage drops, and loads. Troubleshooting the SunWide controller is simple. Some basic troubleshooting procedures are listed below. CAUTIONS: 1. - Page 22 troubleshooting the problem. Check that the load is turned on. Check that no system fuses are defective. Check that no system circuit breakers are tripped. Remember that there are no fuses or circuit breakers inside the SunWide. Check connections to the load, and other controller and battery connections. Make sure voltage drops in the system wires are not too high.
