TOPBAND 6 INPUT 1 OUTPUT AC COMBINER BOX

For the use of large-scale photovoltaic power generation system with string inverters, in order to reduce the line connection
between the PV inverter and power cabinet, convenient construction and maintenance, improving the reliability of the system,
we need to install a confluence device between the collecting device and the grid connected PV inverter cabinet.

Our company produces the PowerSA-SUNac series AC PV junction box in order to satisfy the requirement of specially designed
outdoor AC products, solutions of photovoltaic power generation system and PV inverter products complete. 

Product functions

Support lighting protection, short circuit protection, ground protection, reverse current protection

Support current, voltage and temperature monitoring of PV arrays

Support fault alarm and location of cells PV arrays

Support fault alarm and location of fuse

Support remote SCADA system diagnosis of PV arrays.

Product Features

1.The protection level of the product reaches IP65.

2.To meet the requirements of simultaneous access multi-channel series inverter, each line is protected by a hot magnetic
circuit breaker, and the rated voltage is reached above AC480V.

3.The special high voltage lightning protector can meet the over-voltage and lightning protection of three-phase, and the
working voltage is more than AC480V.

4.All the buses in the box are connected with the bus after plating or purification, so as to reduce the internal resistance
and the connection point of the bus.

5.The output is circuit breaker, load disconnecting switch or fuse output.

Main pamameters:

High quality cold rolled steel plate box equipped with metal clasp.

IP67 waterproof terminals, superior deal with extreme outdoor weather.

In order to ensure the high quality of products, we guarantee 100% full inspection from incoming materials to shipping.

Intelligent Monitor Moudel For Optional

Function:

Out intelligent monitoring unit can monitor the working condition and fault state of each PV battery string, provides lightning protection, short circuit protection, and earthing protection on PV battery series. Which can also monitor the temperature of solar panel cell. Software reference as below:
