Energy Storage

An inverter is an electrical device capable of altering the voltage, frequency, phase, and other electrical characteristics of a power system. Inverters can be found in a wide range of applications, including electric vehicles, photovoltaic power systems, wind energy systems, and various household appliances like TVs and computers. In the field of photovoltaic power generation, inverters are generally categorized into two types: grid-connected inverters and off-grid inverters. Off-grid inverters refer to electrical systems that operate independently of the public power grid. They typically consist of manageable modular components to form a self-contained small-scale electrical network. These systems store the DC electricity generated by solar panels in batteries, and this DC power is then transmitted to the off-grid inverter for conversion into AC electricity, which can be used to power electrical loads. Off-grid inverters are especially suitable for remote areas where access to the main power grid is difficult, such as deep within mountains, deserts, and wilderness, and they provide an on-demand power source to meet electricity needs at any time and in any location.

In the field of photovoltaic power generation, inverters are generally categorized into two types: grid-connected inverters and off-grid inverters. The primary characteristic of grid-connected inverters is their higher power capacity and relatively lower cost. They enable precise control of electric energy and do not require energy storage. DC electricity generated by photovoltaic systems is converted by grid-connected inverters and then directly fed into the public electrical grid. This ensures that the AC electricity is fully synchronized with the public grid, meeting the required frequency and phase characteristics of AC power.
