Let’s Create a Simple Solar System with Acoucou LiFePO4 Batteries

Main components

  • Solar panel

There are mainly two kinds of solar panels: monocrystalline and
polycrystalline silicon solar panel.

Monocrystalline panel: its four corners are shaped in a circular. The photoelectric conversion efficiency ranges from 15% to 24%, which is the highest among all types of panels. The lifespan can generally reach 15 years, with a maximum of 25 years. The cost is higher, so it is more expensive.
    Polycrystalline panel: its four corners are square angles. Its photoelectric conversion efficiency is about 16%. The lifespan is usually shorter than the monocrystalline panel. It is cheaper than monocrystalline panel, with simple material manufacturing, energy saving, and lower overall production costs

  • Controller

PWM: its cost is lower because of the simple structure and mature technology, and it is suitable for small systems.

MPPT: it is more expensive because of its complex structure. It possesses superior energy conversion efficiency and is suitable for large systems or situations with poor environmental conditions.

When selecting a controller, we should ensure that the voltage it supports matches the voltage of the solar panel and battery. The common system voltages are 12V, 24V, and 48V.

  • Inverter

Pure sine wave inverter: its output waveform generated is very close to the standard sine wave, which is basically consistent with the AC waveform of the power grid, and can be approximated as a smooth curve. The output waveform is similar to that of a home power supply or commercial power grid, and it is suitable for devices with high requirements for power waveform. Therefore, it is more expensive.

Modified sine wave inverter: the output waveform is achieved through a stepped waveform that approximates a sinusoidal waveform. They usually use simpler circuit designs, so it is cheaper. It is not suitable for inductive loads, but usually still meets the needs of most household appliances.

When selecting an inverter, its rated power should be greater than the total load, and the voltage should be the same as other devices

  • Battery

Lead-acid batteries and lithium iron phosphate batteries are currently the mainstream. Compared to the two types of batteries, lithium iron phosphate batteries, although more expensive, have better quality and longer lifespan, which is a better choice. In order to meet people's continuous pursuit of quality of life and safety, AcoucouBatteries continuously improves technology, ensures quality, and provides customers with higher-quality products and services.


Advantages of LiFePO4 Batteries

Then, we will talk about how to create a simple solar system.

Step 1: connecting Acoucou battery and controller

You can pull the cables to check whether they are loose with the controller.

Step 2: connecting solar panels and controller

If we connect solar panels and controller first, they will be burnt out. Thus, connecting the battery and the controller should be done first.

Step 3: connecting Acoucou battery and inverter

Disconnect the controller and solar panels, and the controller and the battery. First, use cables to connect the inverter. It is recommended to install a fuse on the end of the positive cable near the battery. Then, use the bolt on the cable connecting the fuse to place on the positive battery terminal. generating spark is normal. Finally, the controller is connected to the battery, and then it is connected to solar panels.




 Building a solar system is an effective way to reduce your carbon footprint while enjoying long-term cost savings. You can have a preliminary understanding of building solar energy by following this guide and seeking professional advice when necessary, you can build a solar system tailored to your energy needs. Embrace the power of the sun and contribute to a sustainable future.
