Power-One, a member of the ABB Group and the world's second largest designer and manufacturer of photovoltaic inverters, announced today the company will showcase REACT at the 29th Symposium Photovoltaische Solarenergie at the monastery Banz near Bad Staffelstein, Germany.
From Wednesday to Friday, visitors will see Power-One's first 4.6 kW/2 kWh energy storage system which enables self-consumption and energy independence for home owners.
And symposium attendees can also take a closer look at Power-One's smallest transformerless string inverters: the three-phase TRIO-5.8/7.5/8.5 for residential applications.
"The Symposium Photovoltaische Solarenerergie is the place to meet the German PV industry as well as to discuss the opportunities and challenges of photovoltaics and the renewable energy generation in general," said Gerhard Schackert, local sales director for PG Solar, Germany, at ABB.
"We are looking forward to this special event as well as to presenting our latest products to its select audience."
Power-One's residential energy storage system REACT (Renewable Energy Accumulator and Conversion Technology), which will be available this year, allows home owners to store excess energy produced by their PV installation during peak times for periods with higher energy demands.
The solution consists of a 4.6 kW or 3.6 kWh, respectively, single-phase Power-One inverter and a lithium-ion battery providing 2 kWh of usable energy.
Due to its dual MPPTs, broad input voltage ranges and high efficiencies, the integrated inverter offers maximum installation flexibility for optimal energy harvesting.
To allow system operation in the event of a power outage, Power-One also plans to integrate basic load management outputs and an auxiliary AC output.
The energy storage system has been designed for a long life-cycle with a ten-year expected battery life.
The solution can also be expanded by additional battery modules to up to 6kWh of usage energy.
Due to the integrated Ethernet port, the energy storage system allows for remote or local monitoring without additional interfaces.
With an output of 5.8 kW, 7.5 kW, and 8.5 kW respectively, the TRIO-5.8/7.5/8.5 are Power-One's smallest transformerless three-phase string inverters and ideally suited to the needs of the residential market.
Like all members of the TRIO string inverter family, the compact devices benefit from a redesigned topology used in Power-One's TRIO-20.0-TL-OUTD and TRIO-27.6-TL-OUTD, thereby ensuring high conversion efficiencies of up to 98% across a wide voltage range.
The high-speed MPPT algorithm enables real time power tracking as well as improved energy harvesting. Both, the TRIO-7.5 and the TRIO-8.5, feature two independent MPP trackers, offering maximum installation flexibility for optimal energy harvesting.
The new TRIO inverters are equipped with a sliding front panel with captive screws which makes installation and maintenance processes easy, the connection and configuration area can be accessed without requiring the complete removal of the cove or fumbling with loose screws.
A graphic display allows for quick connection parameter setting and functional control.
Furthermore, the devices offer integrated power control and monitoring functionality as well as environmental sensor input without external components.
The systems can be extended by an optional expansion card, which gives users access to the ethernet data logger to monitor the installation locally or remotely with a LAN connection.
The three inverters are suitable for unrestricted outdoor use thanks to a robust IP65 enclosure.
At the 29th Symposium Photovoltaische Solarenergie Power-One will present its products at its booth in the foyer east.
