Raw Material Expenses: Raw materials, including IGBTs/MOSFETs, capacitors, PCBs, aluminum heat sinks, transformers, enclosures, are a major part of operating costs. Long-term contracts with reliable suppliers will help mitigate price volatility and ensure a consistent supply.
R ecently, the General Administration of Customs released import and export data for inverters for October 2024. In October 2024, inverter exports reached 4. 3% MoM; imports were 131,300 units, down 42.
Currently, the common module auxiliary materials include PV busbar, PV Interconnector There are eight kinds of auxiliary materials, including PV busbar, PV interconnector, tempered glass, adhesive film, backsheet, aluminum alloy, silicone, and junction box.
In a series inverter connection, multiple inverters are connected end-to-end. This configuration increases the total output voltage while keeping the current constant.
Choose inverters with efficiencies >95% for smaller kW scale inverters (less than 10 kW) and >98% for inverters above 20 kW. The temperature range must be wide, wider the better.
