1 Summary

In a large photovoltaic power generation system, it is necessary to connect numerous photovoltaic battery packs in the series and parallel combination to reach the required voltage and current value in order to maximize the power generation efficiency. The main purpose of APV series smart photovoltaic combiner box is to conduct the first-stage confluence for the photocell array input which is used to reduce the wiring between photovoltaic battery array and inverter, optimize the system structure, improve the reliability and maintainability. The APV series smart photovoltaic combiner box not only provides lightning protection confluence function, but also provides the function of photocell current measurement, detection for solar panel operation in the photocell array, battery voltage after confluence, the total confluence power, the branch power, acquisition of combiner lightning protector state, acquisition of DC breaker state, the relay contact output, the interface with the air speed, temperature sensor and irradiator etc. available for customer’s option. The device of standard configuration has a RS485 interface which can upload the picked-up data and equipment state to the monitoring system.

2 Product Designation

*Note: the combiner box with the reverse protection function can only select the TR-punched photovoltaic confluence collection device.

4 Technical Parameters

5 Basic Structure

6 Installation and Use

6.1 Check for the Damage due to Transportation Before installation, check the product for the damage or deformation and check if there is any loosening, fall-off or spoilage with the components inside the box. If any of above exceptions is found, please promptly

stop the installation of product and contact our company. If possible, please provide us the picture of position in question for analysis and disposal.

6.2 Basic Installation Requirements

The protection rating of the product is IP65. The installation environment in design is the outdoors installation. However, because of many precise electronic components inside it, do not place it in a damp location, if possible.

6.3 Overall Dimensions

The dimension of 16-channel box in the product is 700mm×575mm×220mm (Width × Height × Depth), the dimension of 8-channel box is 610mm×410mm×160mm (Width × Height × Depth). The product cannot be horizontally installed and shall be vertically wall mounted. See the below Fig. for the detailed installation dimension.

Note: the imaginary lines in Fig. 4 and 5 are the selectable installation direction.

6.4 Terminal Size and Connection Wire Size

The user can inquire and select the suitable cables for various terminals as per the following table:

6.5 Open and Close the Frame Box

                                                                             Fig. 6 Frame Box Appearance

All the PV array lightning protection combiner boxes of our company have provided a key for opening or closing the box. Notice that the box will be effectively opened or closed only when both locks on the upper and lower parts are unlocked or locked at the same time.

6.6 Input Wire Connection

The positive PV confluence input is located at the left side under the case, the negative PV confluence input is located at the right side under the case. When the user connects the wire, he needs to unscrew the waterproof terminal and then connects the wire with the confluence input wiring terminal, tightens the screw and properly fixes the wiring and at last tightens the outside waterproof terminal (See Fig.7).

6.7 Output Wire Connection

The output of combiner box is located under the case. See the following Fig. for the detail connection

positions.
