Wiring diagrams solar country house

So, the first thing you need to have an idea - what it consists of a set of solar power.Key elements of the system are represented by the following devices:

1. batteries that absorb sunlight.The modules convert natural light into electric energy.
2. charge-discharge battery controller, which monitors the battery voltage.If during the day recharged batteries (14 volts at the terminals), the controller switches off the charging process.If the batteries run out during the night (very low voltage - 11 volts), the controller prevents further operation of power plants.
3. battery, which is designed for storing the generated electricity.
4. Inverter - converts 12 volts to 220 variables necessary for the operation of home appliances, lighting systems and domestic appliances.

draw your attention to the fact that among all devices: controller, inverter, the load and the battery, it is desirable to put the fuses that protect the system in the event of a short circuit in the network!

In the simplest design scheme of connecting solar panels to the controller, battery, inverter and the load is as follows:

As you can see, much difficulty in connecting not important to respect the polarity and connect all plugs in the right sockets controller.In this embodiment, it is very difficult to mix something.But if you decide to use energy from the sun at the same time to the fixed network, solar wiring diagram should look like this:

Here it is necessary to clarify: redundant load - is emergency lighting, boiler and, for example, a refrigerator.Not redundant - home appliances, light in the house, etc.The greater the capacity of the battery, the longer it will be able to work out the redundant electrical offline!

to the wiring diagram of solar panels to AC power clear.Now we need to see an equally important part of the question - the correct connection between panels.

One panel is connected to the controller without problems - plus and minus must be connected to the corresponding terminals of the controller.But what if you have more than the batteries in the system?Here you can use one of the following schemes junction solar panels:

• Parallel .In this case, you need to connect the terminals of the same name with each other: positive to positive, negative to negative.As a result, the output voltage will remain of the same 12 volts.
• Serial .Plus the first panel to be connected to the negative terminal of the second.The remaining second battery plus and minus first need to connect to the controller.Bottom line - the output of 24 volts, which may sometimes be needed in the home.
• Mixed (series-parallel).The scheme of connection of solar panels involves connection of several battery groups.Within each group of devices connected in parallel, and only then in series as shown in the picture.This option will make the most appropriate output voltage characteristics.

That's all that I wanted to tell you about the connection diagrams country house solar panels to the AC mains.As you can see, the wiring harness is not difficult, the main thing to be careful and to determine what the load is to be output.A very important point, on which I would like to finish this article - in any case, do not connect the inverter directly to the controller.Such a compound would be disastrous for the domestic power!
