February 14, 2025: Exide Technologies has partnered with Dutch energy broker Vrijopnaam for an energy storage and grid management system in the Netherlands.

Exide said on January 29 its Customized Energy Systems (CES) unit had deployed the group’s 3.4MWh Solition Mega Three lithium ESS with liquid cooling as part of a bespoke solar power system.

Exide and Vrijopnaam jointly developed the overall power system, which stabilizes fluctuations in solar energy and includes in-front and behind-the-meter capabilities. The former sends power through a meter before it reaches its destination, while the latter supplies energy for on-site use, without passing through a meter. 

Exide said the set-up allows greater control over energy consumption while allowing better grid integration — giving Vrijopnaam the flexibility to offer both energy storage and power generation to consumers.

Founded in 2015, Vrijopnaam is best known for its ‘Paneelopnaam’ concept, which allows individuals to own part of a solar park and benefit from its energy production. 

For a nominal fee, customers can buy a panel generating 250MWp (megawatt peak). They own the panel for nine years and use it to produce their own solar energy.

Vrijopnaam guarantees a minimum annual yield of 250kWh per panel, which is deducted from customers’ energy bills.

CES sales director Jeroen van Hapert said the collaboration set a benchmark for how energy companies can work together.

Batteries International reported last month that Exide was using its Solition tech to support telecom base transceiver stations in stable, poor, and off-grid applications.

Designed for either new installations or a replacement for existing lithium or lead batteries, Solition blends battery modules, a built-in BMS and LiFePO4 cell chemistry.
