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.
