GoodWe named best Asian manufacturer in 2022 SPI test

By GoodWe

GoodWe has taken part in PV storage testing by the University of Applied Sciences (HTW) in Berlin for the third consecutive year, with a total of 21 different storage systems in the 5 and 10 kilowatt power classes examined to determine System Performance Index (SPI). The two GoodWe hybrid inverters tested, the ET and EH, achieved an SPI of 93.4% and 91.2% respectively, together with BYD batteries.

With its exceptional system efficiency, the GoodWe 5000-EH secured 2nd place in the smaller reference category (5MWh/a consumption with 5kWp PV), with the GoodWe 10k-ET also performing well, only  1.7 percentage points away from the best-placed system in the second reference category (10 MWh/a consumption with e-car and heat pump).

The System Performance Index determined by the HTW researchers is an economic index and indicates how much the storage system tested reduces electricity costs compared to an ideal system. 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, with the larger the PV system, the higher the saving on CO2 emissions.

GoodWe ET PLUS+ series, three-phase energy storage inverter

With smart optimization of energy autonomy across residential ecosystems and operating at the heart of the integrated PV power and storage system, GoodWe’s ET Plus+ hybrid inverters are designed to maximize energy output, enhance self-consumption and facilitate back-up power. With intelligent load control and a wide battery voltage range, the set-up can be flexibly configured to meet individual needs across the residential ecosystem. Combination with the GoodWe Lynx Home F battery system provides a safe and reliable energy storage solution.

Lynx Home F series, high voltage battery

The Lynx Home F series is perfect for residential solar systems, providing a safe and convenient HV battery system for PV power back-up and energy autonomy. The stackable, self-detecting battery modules make the system especially easy to install, while the reliable lithium iron phosphate (LFP) battery cell technology ensures maximum safety.

The Lynx Home F offers a wide capacity range from 6.6 kWh to 16.4 kWh and is compatible with GoodWe BH/EH/BT/ET inverters.

GoodWe EH Series, single-phase energy storage inverter

The GoodWe EH Series is a single-phase, on-grid inverter that is designed to maximize self-consumption of PV energy and is compatible with high voltage batteries to empower flexible system design. At the core of a reliable electricity supply, the EH series can automatically achieve UPS-level switching to back-up mode in less than 10 ms, ensuring that critical loads experience no interruption. Communicating via multiple protocols, it allows for smart home integration and maximized system status transparency.
