Description

An integrated skid device for off-grid photovoltaic power generation

Technical Field

The utility model belongs to the technical field of photovoltaic energy storage, and specifically relates to an integrated skid device for off-grid photovoltaic power generation.

Background Art

Photovoltaic power generation plays an increasingly important role in today's society. It not only helps protect the environment, but also provides a sustainable solution for global energy supply. By utilizing solar energy resources, photovoltaic power generation can convert sunlight into electrical energy to meet people's energy needs. Among them, off-grid photovoltaic power generation systems are suitable for areas where there is no grid connection or the grid power is unstable. Off-grid photovoltaic systems are usually composed of solar panels, controllers, inverters, battery packs and bracket systems, and are generally split structures. They generate DC power that can be directly passed during the day or stored in battery packs to provide electricity at night or on cloudy or rainy days. The existing off-grid photovoltaic power generation equipment is basically built on a cement foundation. If you want to transfer it for use, you have to dismantle it on site and reinstall it. The whole process is troublesome and time-consuming, and it also increases labor costs.

Currently, no effective solution has been proposed for the problems in the related technologies.
