The Chinese manufacturer has launched a new series of three-phase hybrid inverters ranging from 80 kW to 100 kW. The new products feature eight MPPTs with an input current of up to 42 A.
Chinese inverter and energy storage manufacturer GoodWe has launched three new three-phase hybrid inverter models for commercial and industrial (C&I) applications.
The new inverters are part of the company’s ET series and have an output power of 80 kW, 99.99 kW and 100 kW respectively, and a maximum PV input of 160 kW, 200 kW and 200 kW respectively. The 80 kW and 100 kW models can also operate continuously at 110% output power without mains power.
“The ET 80-100 kW significantly increases energy yield even in complex C&I scenarios, offering eight MPPTs with up to 42 A input current, or 21 A per string, making it compatible with M10 and M12 module sizes,” the company said. “AC and DC coupling offer great flexibility and efficiency. AC coupling is ideal for adding storage to existing PV systems without changing the original PV wiring, MPPTs, cables or PV inverters. DC coupling, on the other hand, reduces conversion stages to reduce energy losses and improve return efficiency by more than 2%.”
All models have a maximum efficiency of 98.1% and are reportedly capable of delivering 120% of output power for one minute and even 150% for 10 seconds. For larger projects, the ET 80–100 kW can be paralleled in systems of up to 15 units via the SEC3000C smart energy controller.
“When combined with GoodWe’s Static Transfer Switch (STS) 125 kW, the ET delivers 80-100 kW UPS-level switching with a transfer time of less than 4 ms, allowing critical loads to continue operating without interruption despite grid disruptions,” the company said. “In combination with GoodWe’s high-voltage BAT 112kWh batteries, the ET 80-100kW forms an easy-to-implement, optimally matched storage solution. This pairing allows the battery to discharge close to its maximum capacity and ensures high power performance.”
The inverters have an IP66 protection rating, an operating temperature range of -35 C to 60 C, a relative humidity range of 0-100% and a maximum altitude of 4,000 m. It measures 99.5 cm x 75.8 cm x 35.8 cm and weighs 97 kg. It has a noise emission level of less than 60 dB. Reverse rotating fans support dust removal, making the inverters suitable for dusty outdoor and industrial environments.
“Terminal temperature monitoring on both AC and DC connections helps prevent overheating and ensures safe operation. Additional protections, including PV system reverse polarity protection and ISO protection, protect the system from risk,” the company added. “The smart DC circuit breaker option can be selected on a case-by-case basis and adds an extra layer of protection. It automatically trips in the event of reverse polarity, DC connection overheating or internal short circuit, quickly isolating faults to protect both equipment and personnel.”
