Finland’s ABB announced this week that it is seeking partners to trial an integrated microgrid solution.

The company’s new MGS100 solar PV and battery energy storage system is planned to be widely available at the end of this year.

The containerized system uses solar power during the day, switches to battery mode after dark and only uses an AC generator for the rest of the night if the battery runs out, ABB said. Any excess energy produced during the day is used to charge the batteries.

Three power ratings are available: 20 kW, 40 kW and 60 kW nominal load power.

ABB said the system can be connected to multiple power sources to provide electricity for remote off-grid locations, or backup power for small commercial and industrial facilities where grid power is unreliable.

ABB’s President of Electrification Products, Tarak Mehta, said the system is “the first microgrid solution of its kind that makes access to affordable and reliable power a reality, creating life changing opportunities, improving basic living standards and unlocking economic development.”
