1-6 Installation Overview The installation is straight forward but it is important that each step is done correctly and safely. A mistake can lead to dangerous voltage and current levels. Be sure to carefully follow the following instructions for all the terminal connection.
Dip Switch 7 ON: Lighting control OFF: Load Control Lights remain turned off. OFF: 2,4,6,8,10: Lighting control Switch Hours light is turned on after sunset. 2/1, 3/1, 4/1, Light is turned on after sunset, turned off after the selected 6/1, 2/2, 3/2, lasting hours, and turned on again before sunrise. 2/1: Light is turned on for two hours after sunset, turned off 4/2, 6/2, after two hours and turned on again one hour before sunrise.
Solid Green: Battery discharges to DC load; after six minutes of reconnection process, the green LED will be lit to show battery successfully discharges to DC load Solid Red: Load control in fault: Load Over Current Blinking Red: Load control in fault: Over Temperature Push Buttons Press the Light Test Push Button to enter the testing mode to check if the Lighting Control Switch has been correctly set in order to control the lights based on desired timer. Light Test Procedure: 1.
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: z The SunWide prevents reverse current leakage at night, so a blocking diode is not required in the system. z The connector terminals will accept a maximum wire size of AWG #10 (up to 5.2 mm2). A flathead screwdriver is required. (Some #10 spade connectors may not fit in this terminal.
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. If the PV array is disconnected, it is best to disconnect the battery and restart the microcontroller before leaving the site. ※ Remember that the Solar array will generate power whenever in sunlight.
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. Solar Battery Charging The energy output of a solar array is used for recharging the system battery. The SunWide manages the charging process to be efficient and to maximize the life of the battery.
VOLTAGE Four Stages of Solar Charging 3 EQUALIZE NIGHT 1 BULK CHARGING 2 PWM ABSORPTION 4 FLOAT 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. This is to avoid over-heating and over-gassing the battery. The current will taper off to safe levels as the battery becomes more fully charged. 3.
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. These standard algorithms are suitable for lead-acid batteries ranging from sealed (gel, AGM, maintenance free) to flooded to L-16 cells and Ni-cad etc.
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. Temperature Effects Battery Temperature Sensor (BTS) A sensor next to the remote panel is used for temperature compensated battery charging.
10ºC / 50ºF + 0.45 V 5ºC / 41ºF + 0.60 V 0ºC / 32ºF + 0.75 V Temperature Compensation + 0.90 V + 1.20 V + 1.50 V + 1.80 V + 2.40 V + 3.00 V Equalization Routine equalization cycles are often vital to the performance and life of a battery — particularly in a solar system. During battery discharge, sulfuric acid is consumed and soft lead sulfate crystals form on the plates. If the battery remains in a partially discharged condition, the soft crystals will turn into hard crystals over time.
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. Hold the pushbutton down for 5 seconds to start or stop an equalization (depending on whether an equalization is in progress or not).
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. When the battery is fully recharged, there can be no more chemical reactions and all the charging current is turned into heat and gassing.
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 turns.
The specifications for the diode follow: • 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.
2-4 Adjustability of Lighting Control When setting in the lighting control mode, DIP Switch 7 should be placed at ON. After completing the system connections, select the desired LIGHTING CONTROL switch option. The brief description of the options follows below: 2,4,6,8,10: Lights remain turned off. Hours light is turned on after sunset. 2/1, 3/1, 4/1, 6/1, 2/2, 3/2, 4/2, 6/2, 8/2: Light is turned on after sunset, turned off after the selected lasting hours, and turned on again before sunrise.
LIGHT TEST Button Press the LIGHT TEST button to enter the testing mode to check if the Lighting Control Switch has been correctly set in order to control the lights based on desired timer. The procedure is listed as below. STEPS: 1. Select Dip Switch 7 to be ON 2. Press LIGHT TEST push button until the LOAD LED blinking in green and red in turns. 3. The light will be lit on when the power circuit is operating well. 4. Press LIGHT TEST push button to return to charge battery/load control state.
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. Troubleshooting should be done by qualified personnel only. 2. Remember that a battery can cause serious damage if shorted. 3. There are no user serviceable parts, fuses or circuit breakers inside the SunWide.
z z z z z z 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. Check for proper LED indications on the SunWide.
