Battery maker Trojan claims its new proprietary ‘Smart Carbon’ technology can improve the cycle life of lead acid batteries by as much as 15%, through effective management of the cell in a partial state of charge.

Certification for safety and other technical standards must become uniform in the market for residential energy storage systems which can combine with PV systems, according to an expert at technological research institute Fraunhofer ISE.

Some home energy storage systems, such as those increasingly used with PV, have potential safety flaws that could lead to an increased risk of fire, according to a study by German researchers.

Bosch claims it has developed an energy management system for optimising electrical and thermal energy consumption from solar power systems, which the company will launch at this year’s Intersolar exhibition and conference.

NEC Corporation has commissioned a 2MWh lithium-ion battery energy storage system designed to ease the integration of renewable energy into the grid for Italian distribution system operator (DSO) Enel Distribuzione.
