Page 5: General Information
1 General Information 1.1 Overview SOLAR-CMP40AN controllers, based on a new design concept, adopt the solar charge controller as the main component. Adopting the advanced MPPT control algorithm, the controller can minimize the maximum power point loss rate and time. It makes this product tracks the PV array's maximum power point and obtains maximum energy under any situation. - Page 6 Charging power reduction automatically for over-temperature • RS485 communication interface for remote monitoring • Standard Modbus communication protocol based on the RS485 communication bus, extending • the communication distance A power protection chip, which can provide 5VDC/200mA power and over-current, short-circuit •...

Page 9: Connection Diagram
1.3 Connection diagram The cable length of the battery should not exceed 3 meters. The recommended cable length of the PV array should not exceed 3 meters (Note: If the cable length of the PV array is less than 3 meters, the CAUTION system meets EN/IEC61000-6-3 requirements. - Page 10 Our company's MPPT algorithm continuously compares and adjusts the operating points to locate the array's maximum power point. The tracking process is fully automatic and does not need the user's adjustment. As Figure 1-2, the curve is also the array's characteristic curve; the MPPT technology will 'boost' the battery charge current by tracking the MPP.

Page 11: Battery Charging Stage
Figure 1-3 Multi-MPP Curve Suppose the program works improperly after appearing Multi-MPP. In that case, the system will not work on the real max power point, which may waste most solar energy resources and seriously affect the system's normal operation. The typical MPPT algorithm, designed by our company, can track the real MPP quickly and accurately. - Page 12 A) Bulk Charging The battery voltage has not yet reached constant voltage (Equalize or Boost Charging Voltage). The controller operates in constant current mode, delivering its maximum current to the batteries (MPPT Charging). When the battery voltage reaches the constant voltage set point, the controller will start to operate in constant charging mode.
- Page 13 Due to the installation environment or load work, the system may not stabilize • the battery voltage at a constant voltage. The controller will accumulate the time when the battery voltage is equal to the set value. When the accumulative time is equal to 3 hours, the system will automatically switch to float charging.

In that case, larger wires can be used to reduce the voltage drop and improve performance. - Page 17 Installation procedures: Step 1: Determine the installation location and heat-dissipation space Figure2-1 Mounting Step 2：Connect the system in the order of battery -- load --PV array following Figure 2- 2," Schematic Wiring Diagram," and disconnect the system in the reverse order.

- Page 19 according to the practical application, the negative terminals of the PV array, battery, and load can also be ungrounded. However, the grounding terminal on its shell must be grounded. It shields electromagnetic interference and avoids electric shock to the human body. It is recommended to use a common-negative controller for common-negative systems, such as the RV system.

4 Others Protection Protections Instruction When the actual PV array's charging current or power is higher than PV Over Current the controller's rated charging current or power, the controller will charge the battery per the rated current or power. Not in the PV charging state, the controller will not be damaged when the PV array is short-circuited. - Page 31 the detected temperature is higher than the LTPT, the controller will work automatically (The LTPT is 32℉(0 °C) by default and can be set within 50℉ ~ -40℉(10 ~ -40 °C)). When a short circuit occurs on the load side (four times higher than the rated load current), the controller automatically cuts off the output.
