If you are interested in the topic of how to connect a solar panel, you should study the installation and device features well. It is also worth asking yourself the question ? what is a home power plant for, and what is the main purpose of its installation. As practice shows, there are several answers here: the fight against constant power outages, energy savings and the ability to create a completely autonomous power grid. When the main goal is defined, then it is already possible to approach the technical side of the issue. The prepared article will tell you how to connect a solar battery from Tindo Solar and other Australia of such a system.
Different types of solar panel power plants ?
In order to understand the connection diagrams well, you need to familiarize yourself with the complete set of equipment for a small Tindo Solar solar system. It is worth clarifying that solar power plants are networked and autonomous, so their set of equipment is slightly different. For example, the network type of Solar Panel in Australia is successfully used in shopping malls, offices, private houses, farms, hotels, and the list of components is as follows:
Solar panels of poly-crystalline or mono-crystalline type.
A single-core copper cable, always with high-quality double insulation and good resistance to the influence of a rather aggressive environment. The recommended cross section is 6 mm or more.
- Switches of direct and alternating current.
- Quick connectors for connecting panels.
- DC SPD.
- DOKA sensor.
A reversible electricity meter is necessary in cases where it is planned to sell electricity to the state. Autonomous solar power plants Tindo Solar is supplied in the following configuration:
solar panels of a certain type;
- Battery charge controller;
- The inverter is not include in every kit;
- Several options for batteries (often gel);
- Protection devices (fuses, circuit breakers);
- Cables with a cross section of at least 4 mm.
Autonomous Tindo Solar kits are used in most cases for street lighting, motorhomes, yachts, traffic lights, automatic power supply, as well as in houses where there is no central power supply and, accordingly, the possibility of connection. An ideal option that, for little money, allows you to create an autonomous power grid and use various electrical appliances, even far from civilization.
If the solar system is equipped with batteries, then it is important to pay attention to the following parameters:
- Rated voltage of panels: 24V or 12V: open-circuit voltage value (denoted Voc), which characterizes the amount of voltage generated by the Solar energy in Australia when there is no load.
- An important parameter when choosing a controller;
- Current Imp – current at the maximum possible power of the panel.
Why do you need a network power plant Tindo Solar ?
To start with, a network solar power plant is a good way to significantly reduce the monthly payment for electricity, given the constant rise in the cost of energy. This equipment does not require drives and is specially tuned for savings. This type of Tindo Solar power plants are in particular demand among owners of commercial real estate, because the cost of 1 kWh is much higher compared to the private sector.
Private households are also showing interest in network power plants, because electricity can be sold at a “green tariff”. That allows you to save well on utility bills, spending the family budget more economically and reasonably. Despite the price of 1 kWh, as well as the price of periodic maintenance. And all the costs of installing a solar station, this investment is more than profitable. Indeed, for a long service life (panels up to 30 years), the power plant will pay for itself more than once, however, for more detailed calculations, you need to know the exact configuration.
There are 3 possible schemes that will help connect Tindo Solar Panel Sydney to each other: parallel, serial, and series-parallel. More on each of the schemes below.
1. Parallel connection
In order not to make a mistake, you just need to connect terminals of the same sign to the outputs and inputs of the panels. The most convenient type Y connectors.
Thanks to this scheme, it is possible to increase the current, while not increasing the voltage of the panels. For example, there are 4 panels from Tindo Solar and each 12V, at a voltage of 22.48V, the maximum current is 5.42A. By measuring the open circuit voltage and the rated voltage, you can see that the indicators have not changed. However, the maximum power looks like 5.42A * 4 \u003d 21.68A.
2. Serial connection
It can be seen from the diagram that the negative terminal from the first solar panel is connected to the positive terminal of the second. And the negative terminal of the second to the third terminal and further according to the same scheme. With this connection, the voltage indicators of the panels are summed up. The circuit will even achieve an indicator of 220V, but this is done extremely rarely.
3. Series-parallel connection
The above diagram contains panels that are partly connects in parallel and partly in series. This feature allows you to select the most optimal mode of operation of the power plant. Thanks to the regulation of the output current and rated power.
