4. Make appropriate over-assignment according to your location (only the converter can be over-assigned by a maximum of 135%, not the power optimizer or the series)

Design Principles and Technical Information

Design Planning

When you want to invest in a solar power station, you need to consider how many solar panels to install and which types of converters to install, and how many strings of modules a converter should correspond to and how many modules a group of strings contains, etc. Maximize power generation efficiency and accelerate the return on your investment.

New Monitoring Platform Power Station List

SolarEdge's new monitoring platform power station list speeds up and simplifies the power station screening function, and can view specific information according to your search criteria, making the installer's power station management simpler, faster and more efficient.

General Rules

  • 1 kilowatt of solar modules can be installed per 7 square meters.
  • On average, each solar module has 295 watts, 9.2 amps, 32 volts, and is composed of 60 small batteries.
  • Different inverters have different The best DC voltage input.
  • Each solar module is 1.8 meters long and 1 meter wide.
  • Each SolarEdge power optimizer (P650) can be installed corresponding to two solar modules Design principles and technical data

Steps to Install and Design a Solar Power Plant

1. Choose the Most Suitable Inverter and Solar Module to Design Your Power Station 2. Choose a Power Optimizer 3. Please Remember that Each String Must Follow One of the Following Rules 4. Make Appropriate Over-Assignment According to Your Location (Only the Converter Can be Over-Assigned by a Maximum of 135%, not the Power Optimizer or the Series)

A. Oversizing of Power Optimizer

2 to 1 series setup, for example P405 : When connecting 2 modules to 1 power optimizer (P405, P650, P730, P800s, P800p), make sure that the combined Voc or Isc does not exceed the power optimizer rating .

B. Oversizing of SolarEdge Inverters Example

Oversizing - For example a three phase inverter, overmatching can up to 135%

C. Oversizing Exception

The inverter can be overmatched by up to 135% (37.25kWp DC), and the maximum capacity of the series：11.25kW

D. String Oversize Up to 13,5kW Per String If：

  • Use a P650 or P730
  • An inverter connect three strings
  • The difference between any two strings cannot exceed 2000W：the maximum module difference between strings is 6 modules
