What is an off grid inverter?

The off grid inverter is an electronic device that converts the 12V/24V/48V/60V/72V DC power provided by the battery into 220V AC power, and converts the mains power into DC power to charge the battery. At the same time, it is not only an inverter used in solar power generation systems, but also an important part of solar power generation systems.

What is the service life of off grid inverters?

The off grid inverter is composed of structural parts, circuit boards, power switch tubes, capacitors, LCD screens and fans. The service life of off grid inverters can be explained by the "barrel theory". The maximum capacity of the wooden barrel is determined by the shortest plank. The service life of off grid inverters is determined by the components with the shortest service life.

Electrolytic capacitors are indeed one of the most prone to failure of off grid inverters. There is electrolyte in the electrolytic capacitor. Over time, the electrolyte of the offline inverter may evaporate and become dry, which will increase the equivalent series impedance of the electrolytic capacitor and decrease the efficiency of use. In the case of passing the same current, a higher ESR will cause the capacitor to heat up, which will further aggravate the evaporation of the electrolyte, forming a vicious circle, and ultimately leading to the failure of the offline inverter. The best capacitor on the off grid inverter is the NCC capacitor. The capacitor specification clearly states: "Please note that the calculated result is not a guaranteed value. When designing the life of the equipment, please review the service life margin. If the estimated life of the capacitor exceeds 15 years, please use 15 years as the upper limit."

In addition to electrolytic capacitors, off grid inverters also have many components with a lifespan of less than 25 years, such as LCD screens, including PVC material connectors, cables, terminals, etc. Thermal grease can produce electronic components in time If there is no thermal conductive silicone grease, the heat generated by the vitality parts can not be conducted in time, then the components will be quickly aging and damaged, but the life of thermal conductive silicone grease is generally about 10 years.

What are the main applications of off grid inverters in the communications field?

off grid inverters can provide AC auxiliary power for DC power supplies.

Some maintenance tools require AC power. DC power cannot provide AC power and can be provided with the help of inverters.

off grid inverters can provide DC-AC conversion functions for photovoltaic grid-connected power systems.

The off grid inverters can connect the direct current generated by the solar system into alternating current and then input it into the grid.

The above is the relevant information about off grid inverters. At present, the use of off grid inverters has become more and more widespread. If you get more information, please contact Shenzhen Sumry Electronics Co., Ltd.
