Why the stand alone solar system kits need to install the pv array combiner?
I know a lot of people don’t know about the stand alone solar system kits or just a little bit. In stand alone solar system kits design,solar power system supplier will provide pv array combiner in their stand alone solar system kits.So maybe you will think why I need this pv array combiner. Does my stand alone solar system kits be equipped with this pv array combiner? One of my clients asked me a question,doest the pv array combiner must use in the stand alone solar system? So today I want to talk about why the stand alone solar system need the PV combiner and when it need this solar array junction box?
Firstly, The solar array junction box is a wiring device to ensure orderly connection and gather function of solar panels. The solar array junction box can ensure that the stand alone solar system is easy to cut off the circuit during maintenance and inspection, and reduce the blackout range when the stand alone solar system fails.
Secondly, the solar charge controller only has one or two connections. But when you used a lot of solar panel connect with the solar charge controller,the connection will be hard.For example,3KW stand alone solar system have 10pcs solar panel,the solar panel connection is 2pcs solar panel connect in series as a string,5strings connect in paralle.This 5strings will connect to solar charge controller,but the solar charge controller only have 1or 2 input terminals.If you use the solar array junction box you can easily solve this problem. The solar array junction box can have 5input and gether these 5input together to 1 output.
Thirdly, the solar array junction box has lightning protection device so it can protect your solar power kit for home.
Now you know why the solar power kit for home need to install the solar array junction box.So if you have any question about our solar power kit for home design please tell us. We hope we can help you with my professional knowledge.
