home storage

The US battery manufacturer entered the stationary storage business with a new product for residential customers. The lithium iron phosphate (LFP) battery is compatible with new or existing PV systems.

Up to eight battery modules from the Chinese manufacturer can be combined to form a storage system with a capacity of up to 25.6 kWh. According to Sungrow, it is not necessary to wire the battery modules.

Poland-based Green Cell is offering two versions of its new inverter, with power outputs of 1 kW and 3 kW. The inverters feature an efficiency of 90% and are recommended for small buildings such as cottages or year-round homes.

The “Global PV Installer Monitor 2020/2021” reports shows that nearly two-thirds of French PV installers now integrate storage solutions into their product portfolios. EUPD Research said this is a clear sign that rising electricity prices and demand for electric vehicles are creating new business models.

Silicon Valley-based start-up Gridtential has secured $12 million in funds to develop what it calls the world’s first factory-ready, single-block, 24V, deep-cycle lead battery. The product is claimed to be ideal for personal mobility vehicles and renewable energy storage in homes and offices.

Around 88,000 energy storage systems linked to rooftop PV were installed last year in the country, which supports residential batteries through a dedicated scheme.

The system generates electricity and heat for residential houses and small businesses. An integrated energy management system should guarantee maximum self-consumption of the solar power produced.

LG Chem is spinning off its battery business into a new subsidiary, LG Energy Solution. It also launched two new battery series, Resu Prime and Resu Flex. These devices rely on new battery cells with a higher power density and with up to 16 kWh, they have a higher capacity than previous models. The first products are expected to be shipped from February or March 2021.

The country added around 90 MW/100 MWh of new, small-sized storage capacity over the past 18 months. Most of the batteries are in Lombardy, whose administration offers rebates.

After months of preliminary work, the time has come: With its PV+home storage network, sonnen GmbH has received prequalification from TenneT to participate in Germany’s primary control energy market. While it is currently allowed to deliver 1 MW, the goal is to supply 100 MW.
