Solar 2000w inverter pure sine wave off grid

AC Charge Current: 0-35A adjustable

Grid type: Off grid

Type: DC/AC Inverter

Cetification: CE, FCC

Series Combination of PV Cells

If more than two cells are connected in series with each other, then the output current of the cell remains same, and their input voltage becomes doubles. 

The graph below shows the output characteristic of the PV cells when connected in series.

   There is a 50Hz power frequency isolation transformer behind the inverter, which is called a power frequency inverter. The advantages of the power frequency inverter are that the power components are stable and reliable, and the overload capacity and shock resistance are strong. If the load is an inductive load such as a motor with a large impact, but does not move frequently, it is recommended to choose a power frequency inverter.

   The pure sine wave inverter is designed with an isolated coupling circuit, which is complicated and expensive. It can be connected to any common electrical equipment (including TVs, LCD monitors, etc., especially inductive loads such as refrigerators) without interference. According to different situations, pure sine wave inverter power supply is mainly divided into two use cases, AC input power off and DC input power off. If the AC input is cut off, the DC screen or external battery cabinet provided by the power system, post and telecommunications system will provide long-term, uninterrupted power supply to the load equipment through the inverter. If the DC screen is cut off and the inverter is overloaded Or failure, the system will automatically switch to the bypass power supply to ensure the continuity of the system power supply.
