Inverter – the core component in the photovoltaic and energy storage industry
In the process of solar photovoltaic power generation, the current generated by photovoltaic modules is DC power, which requires It can be connected to the grid by converting it into alternating current. On the one hand, the photovoltaic inverter converts the direct current into Alternating current, on the other hand using the MPPT algorithm to ensure the maximum output efficiency of the system, photovoltaic Inverters can usually be divided into centralized, string and micro. The energy storage inverter integrates The function of photovoltaic grid-connected power generation and energy storage power station is the superposition of the two major markets of photovoltaic and energy storage.Raw “cross-products”.
Photovoltaic Inverter: Superposition of Newly Installed and Updated Demands
Since photovoltaic module power generation wants to be connected to the grid, it must be converted by an inverter.Inverters have risen rapidly with the increase in photovoltaic installed capacity. Since 2014, photovoltaic Annual inverter shipments have grown from 39GW to 185GW in 2020, with a compound annual The growth rate was as high as 29.6%. Also the lifetime of the inverter (10-15 years) is usually shorter than that of the components Lifespan (25-30 years), there will be a rapid increase in replacement demand in the future, replacement in 2024 Demand is expected to reach 15GW, driving the market together with new PV installations.
Energy storage inverter: opening up new highlights in the inverter market
The continuous promotion of carbon reduction policies and the instability of wind power have brought huge demand for energy storage.China’s electrochemical energy storage accounts for a small proportion in the energy storage market, but it is increasing rapidly. In 2020, the global new energy storage The increased installed capacity of chemical energy storage reached 4.68GW, an increase of 60%, and the domestic newly added 1.56GW,an increase of 144%. It is estimated that by 2025, the cumulative scale of electrochemical energy storage in my country will reach 35-56GW, energy storage inverter as a direct supporting product necessary for electrochemical energy storage,
We expect it to keep pace with electrochemical energy storage at a CAGR of around 68%.
