How To Determine The Performance of A Microinverter?

Generally speaking, the indicators for judging the advantages and disadvantages of a product include performance, cost, applicability, reliability, etc. For microinverters, power density is a comprehensive indicator of conversion efficiency and cost. For microinverters, power density is a comprehensive index reflecting conversion efficiency and cost, and high power density means higher product integration, which also means higher efficiency and lower cost.

At the same time, higher power density can also improve the portability of the inverter, which is conducive to on-site installation and reduce transport costs. Power range is an indicator reflecting the applicability of microinverter products, the wider the power range covered by the product, the stronger the applicability of the product.

Conversion efficiency is the core indicator of microinverter performance. Higher conversion efficiency means more AC power output with the same DC power input. In addition, the ability to operate multiple units in parallel is also an important reference for evaluating the applicability and reliability of microinverters.

The core difficulty in microinverters lies in the optimisation of the software algorithms and the design of the hardware circuits required to achieve high power density. An increase in power density means achieving a higher power level with the same hardware materials, or achieving the same power level using relatively fewer electronic components.
