Again! GoodWe turns out to be the best Asian manufacturer in 2022 SPI test

As a faithful participant, GoodWe has taken part in the PV storage test by University of Applied Sciences (HTW) in Berlin for consecutive 3 years! The results never let us down. According to this year's examination, GoodWe’s hybrid inverters and high-voltage batteries stole the spotlight once again.


A total of 21 different storage systems in the 5 and 10 kilowatts power classes were examined to determine the System Performance Index (SPI) as part of the "Electricity Storage Inspection 2022". The two GoodWe hybrid inverters tested, GoodWe ET and GoodWe EH, achieved a System Performance Index (SPI) of 93.4% and 91.2% respectively together with BYD batteries.


With this exceptional system efficiency, the GoodWe 5000-EH successfully secured 2nd place in the smaller reference case (5MWh/a consumption with 5kWp PV). The GoodWe 10k-ET also performed very well and is only 1.7 percentage points away from the best-placed system in the second reference case (10 MWh/a consumption with e-car and heat pump). Worth mentioning is that GoodWe has launched the upgraded version ET PLUS+ with greater performance, bringing values of high power generation and charging power for optimal energy harvest. Perfectly compatible with brand new high-voltage battery Lynx Home F Series, GoodWe’s introduces the one-stop-shop energy storage solution to the market.


The System Performance Index (SPI) determined by the HTW researchers is an economic index and indicates how much the tested storage system reduces electricity costs compared to ideal energy storage systems. The better the efficiency-related properties, such as conversion efficiencies, control speeds or standby consumption, the higher the cost savings achieved. The difference one point makes in terms of cost can be determined with a high degree of accuracy.


Another focus of the study is the design of PV storage systems. The simulations and analyses carried out show that sizing the PV system as well as the storage system according to demand is particularly important from an economic standpoint. The larger the PV system, the higher the spared CO2 emissions. Any suitable roof surface should be used to produce solar electricity in order to increase the degree of self-sufficiency and reduce CO2 emissions. The use of the two tested GoodWe hybrid inverters 5000-EH and 10k-ET and the installation of a simple PV storage system pays off for a homeowner not only in terms of CO2 emissions, but also financially, as they can break even within seven years. Based on rising energy prices, the payback period will shorten even further.
