GoodWe GW20K-ET hybrid inverter ET series (DC/WIFI/3P METER)
The trend towards more and more powerful PV modules influences the overall requirements of a PV system. At the forefront of development, GoodWe ET inverters efficiently meet the needs of larger residential and commercial properties with powerful backup power, peak shaving and load management for optimized autonomy and reduced energy costs. The ET series can be combined with numerous HV batteries. GoodWe’s ET-plus series offers three-phase hybrid inverters for high-voltage batteries, which enable even more independence in energy supply and maximize self-consumption through intelligent control of loads and higher charging and discharging performance. The ET series has a power range of 15 kW, 20 kW, 25 kW and 30 kW. It also has a back-up function with an uninterrupted switching time.
Capable of emergency power
- Emergency power with uninterrupted switching < 10 ms.
Highest security standards
- Integrated surge protection type II on the DC side.
- Protection class IP66.
Optimized energy autonomy
- Wide battery voltage range (200 – 800V).
- Supports dynamic active power limitation and load visualization.
Smart and efficient operation
- Supports smart home interactions via different communication protocols.
The GoodWe ET 15-30 series is designed for large PV projects in the residential sector and for small projects in the commercial sector. The highest inverter output on the AC side is 29.9 kVA. A central mains and system protection is not required. The GoodWe high-voltage hybrid inverter has an integrated switch-over device for backup power supply. This enables the inverter to still supply the house with 3-phase emergency power in the event of a power outage. The hybrid inverter is black-start capable and can be recharged with solar power.
- Integrated switchover device for backup power
- Black start capability
- Peak shaving function
- AC charge-capable
- DC overvoltage protection type 2 integrated
- Direct connection to a ripple control receiver
- AC overvoltage protection
