2000W Solar On Grid Tie Inverter MPPT For DC 45-90V PV System LCD Pure Sine Wave Limiter 2years Warranty

Introduction of Sunshine Grid Tie Inverter

• Sunshine Grid Tie Power Inverter is the world’s most technologically advanced inverter for use in utility-interactive applications. This manual details the safe installation and operation of the Sunshine Grid Tie Inverter.
• This integrated system maximizes energy harvest, increases system reliability, and simplifies design, installation, and management.
• The small type solar grid tie power inverter can obtain the solar energy from the solar panel and can tie to the grid through its output cables with no extra equipment. The installation is very convenient and reliable.
• We call the system combined with a small solar grid-tie inverter and solar panels ‘SGPV’. The system includes solar panels and small type grid tie inverter and an installation kit. Solar panels can be mono silicon, polygon silicon, non-crystal film, or any other material that can transform solar energy into electric energy. The power of the grid-tie inverter should be matched to the power of solar panels connected. So the power of SGPV is defined by its solar panels, it can be standardized according to its actual use.
• The inverter can be connected to any outlet of the utility grid at the house. The small grid tie inverter monitors the volume, frequency, and phase of the home utility grid, then produce pure sine wave AC power that the frequency and phase are as same as the grid's, and the volume is a bit higher than the grid's, then according to the current-controlled PWM, to control the output power to the grid. The small grid tie inverter just puts out power when the home grid is on.
• When the sun shines, the PV panel will produce DC voltage, and the grid-tie inverter will change the DC voltage to AC voltage and put out power to the home grid. When the total power of the electric apparatus that is used in the house is larger than the output power of the inverters, these power from the inverters will be consumed in the house, which will slow down the power meter, otherwise, the difference in the output power of the inverter between the total used power of the apparatus will go out from the house to the out grid.

Installation Procedure:

• Considering the total capacity of the grid-tie power system that you need.
• Choosing applicable solar panels for Sunshine Grid Tie Inverter.
• Selecting accessories for the installation of the Grid Tie Power System.
• Select the correct model of Sunshine Grid Tie Inverter.
• Installing solar panels in a suitable place.
• Installing Sunshine Grid Tie Inverter to a suitable place.
• Connecting Sunshine Grid Tie Power System with cables and connectors.
• Grounding the system.
• Completing Sunshine installation map and Connecting the PV modules.

we can see that method 2 is a good choice because, with method 1, the DC cables are thicker, so it is more expensive, and three pairs of connectors for parallel connecting plus three pairs of MC4 connectors should be used.
But with method 2, the DC cables are thin, and just a pair of connectors for parallel connecting and a pair of MC4 connectors should be used.
