Install the unit to the wall by screwing four screws. Refer to right chart. 3.4 Power Connection Wire size The four large power terminals are sized for 14 - 2 AWG (2.5 - 35 ) wire. The terminals are rated for copper and aluminum conductors. - Page 8 Connect the Power Wires WARNING: Shock Hazard The solar modules can produce open-circuit voltages in excess of 100 Vdc when in sunlight. Verify if solar input breaker or disconnect has been opened (disconnected) before connecting system wires. Connect terminals by following below steps (Refer to diagram above): 1.

The RTS cable may be pulled through conduit along with the power wires. Tighten the connector screws with 5 in-lb (0.56 Nm) torque. NOTE: The RTS is optional package. Please check local dealer for the details. CAUTION: The controller will not activate temperature compensate charging function if the RTS is not used. -
Page 11: Communication Connections
A battery voltage sense connection is not essential required to operate your controller, but it is recommended for best performance. The battery voltage sense will ensure that the voltage display in LCD is very accurate. The voltage sense wires should be cut to length as required to connect the battery to the voltage sense terminal. - Page 12 Insert bundled software CD into a computer and follow on-screen instruction to install the monitoring software. For the detailed software operation, please check user manual of software inside of CD.

Page 19: Charging Logic
CHARGING LOGIC 5.1 3-stage Charging In general, this solar charge controller is designed with 3-stage battery charging algorithm for fast, efficient, and safe battery charging. The following picture shows the sequence of charging stages. 1) Bulk charge stage In bulk charge stage, charge current begins to flow, typically at the maximum rate of the charge source. - Page 20 If the elapsed time of absorption stage is over setting value for C-V charging time, it will also transfer to Float stage. 3) Float Stage After the battery is fully charged in the Absorption stage, the controller will reduces the battery voltage to the setting point of Float voltage.

Page 21: Equalize Stage
Float cancel voltage Once the battery voltage drops to setting point of Float cancel voltage, the controller also returns to Bulk charging stage. Float cancel voltage = Floating charging voltage – (1V x battery numbers in series) 5.2 Equalize Stage Equalization function is added into solar charge controller. - Page 22 How to Apply Equalization Function You must enable battery equalization function in monitoring software first. Then, you may apply this function in device by either one of following methods: 1. Setting equalization interval. 2. Or, press the button for 3 seconds until LCD shows “ ”.
- Page 23 If solar charge controller is working in float stage, but at this time, the setting equalization interval (battery equalization cycle) is arrived, it will transfer to equalize stage. Equalize charging time and timeout In Equalize stage, based on maximum charging current of battery equalization, the controller will supply solar power to charge battery as much as possible until battery voltage raises to battery equalization voltage.
