Product Description:

EAPVCB-08/16/18S    

 

To reduce the connection cables between the PV modules and solar inverters, to maintain easily, and improve reliability, in the large-scale photovoltaic power plants of on grid system, it’s necessary to use DC combining device between PV modules and solar inverters. EAPVCB Series PV array combiner box is specifically designed for high performance and high reliability, working with the PV inverter products from East Power to form complete photovoltaic system solutions. With PV array combiner box, and based on the PV inverter input voltage range, users can use certain numbers of PV panels with same specification in serially to form a PV module and connect several PV modules into the combiner box, and going through the SPD and breaker to output, which makes it easier to connect with inverter and also reduced the system installation time. 


● Water protection level is IP65 for outdoor installation 
● Wide range of DC input voltage (Max input open voltage can be up to 1000V)
● Dedicated photovoltaic fuses are used in each input,can bear DC1000V,fuse current can be selected
● Each input fuse is with a fuse holder, easy to replace and repair.
● Special high-voltage PV SPD is used,both positive and negative circuit can be protected
● Golden Sun and CE certifications

·         Q. What's lifetime of a UPS ?

Most plug-in UPS are workable for at least five years. We'd advise you to change the batteries every three to four years. For larger equipment, we maintain equipment for twenty years old and still going strong.

·         Q. How to maintain a UPS ?

There are three simple methods:  Never overload your UPS, never connect any home electronic devices such as cooling fan to your UPS. This may cause malfunction of your UPS. Discharge the battery in a consistent interval, once a month or once two months.  You can do this by turning on the UPS without connecting the mains.

Q:What is the difference between a PV inverter and a solar inverter?
The main component of the inverter is the three-phase bridge converter. The main purpose of the grid-connected inverter is to change the power to DC and change the AC power. The main purpose is to improve the power quality (because the wind power generation is very large
Q:Is the PV inverter a current source or a voltage source?
Inverter is a kind of semiconductor device composed of power adjustment device, mainly used for DC power into AC power.
Q:How the output voltage of the PV inverter and the grid-connected voltage are determined
due to the higher penetration rate of the car to go out to work or travel can be connected with the inverter battery drive electrical and various tools work. The car inverter output through the cigarette lighter is 20W, 40W, 80W, 120W to 150W power specifications. And then a large number of power inverter power
Q:What is the difference between a grid-connected inverter and an off-grid inverter? What are the advantages of a hybrid inverter?
Grid-connected inverter does not need energy storage, but the energy can not be controlled, how much light to send online to the number of online, simply do not want people to the grid does not like.
Q:PV grid-connected inverter and independent inverter in the control of what is the difference
And you said that the independent inverter, said off-grid inverter it, this inverter can not access the mains, the components of the electricity through the off-grid inverter to the battery charge, the battery at night
Q:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Grid-connected inverter does not need energy storage, but the energy can not be controlled, the number of photovoltaic sent to send online how much, simply do not want people to.
Q:The function of photovoltaic grid - connected inverter
By dc / dc conversion to increase or decrease the input voltage, adjust its output to achieve maximum efficiency.
Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
The solar grid-connected inverter is not connected to the grid and can not be directly connected to the load to supply power to the load because there is no voltage.
Q:Photovoltaic grid-connected inverter problem
Hello, the definition of the zero line is not caused by the transformer three-phase electric tail connection? I now do not understand why there is no isolation transformer AC output marked is N (zero line), and it is not the transformer three-phase power of the tail connection leads to, this is the zero line? The The
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
Inverter, a single failure, does not affect other operations, the impact on the grid is small, high reliability.
