How to Calculate Suitable Module in Off-Grid Power Storage System
Jan 07 , 2022
The design principle of the module in the off-grid power storage system is to meet the daily power consumption demand of the load under average weather conditions. That is to say, the annual power generation of the solar cell module should be equal to the annual power consumption of the load. Because the weather conditions are lower and higher than the average, the design of the solar cell module ...

How to ground the household solar power storage systems
Mar 24 , 2022
The service life of a solar power storage systems is more than 25 years under the premise of that the equipment quality and installation process are standardized. Among them, grounding is a very important step. Improper grounding will cause an error due to the device’s low insulation resistance to ground or excessive leakage current, which will affect power generation and may even endanger persona...

The benefits of roof mounted solar system
Apr 20 , 2022
Roof mounted solar systems can serve multiple purposes 1. The solar module of the roof can play the role of "regulating" the indoor temperature. It can cool down and keep warm in summer and winter respectively. In addition, the photovoltaic array absorbs solar energy and converts it into electric energy, which greatly reduces the comprehensive outdoor temperature, reduces the heat gain of the wall...

Why do off-grid power system need batteries
Apr 27 , 2022
Off-grid power systems must be equipped with batteries. The task of the battery is to store energy, ensure the stability of the system power, and ensure the load power consumption at night or in cloudy and rainy days. The system can only generate electricity when there is sunlight. Usually, the power generation is the highest at noon. However, at noon, the demand for electricity is not high. Many ...

How to choose inverter
May 11 , 2022
The selection of solar energy systems has always been a concern for everyone. As the heart of the solar energy system, it is very important to choose a suitable inverter. 1. Single MPPT or Multiple MPPT If the roof orientation is the same (solar panels are in the same orientation), single MPPT can be used. If the roof orientation is inconsistent (solar panels are in different orientations or diffe...

What’s the function of the solar inverter
May 25 , 2022
The solar inverter not only has the function of DC-AC conversion, but also has the function of maximizing the performance of the solar panel and the function of system fault protection. 1. Automatic operation and stop function After sunrise in the morning, the intensity of solar radiation increases gradually, and the output of the solar panel also increases. When the output power required by the i...

Different connection methods of solar mounting structure
Jun 08 , 2022
Welding and assembling are the two main connection methods for solar mounting structure. Welding has lower requirements for angle steel. And it has the advantage of lower price, better connection, firmer, so it’s more common applications on solar mounting bracket. However, the problem with welding is that the joints are prone to corrosion and the maintenance cost will be high. Anti-corrosion work ...
