Energy Management Systems

French engineer André Buhart has published the plans and open-source software to create a DIY “solar energy router” to manage PV overproduction. Depending on the configuration, the device can direct excess photovoltaic energy to water heaters, pool motors, or underfloor heating, among others.

Trina Solar has agreed to supply more than 700 MW of high-efficiency PV modules for projects in Spain and Italy under a five-year deal with Verbund Green Power, while EVE Energy says it will invest CNY 8.65 billion ($1.2 billion) in a new battery plant in Kedah, Malaysia.

Oversupply of lithium-ion battery precursor and active materials – and of lithium iron-phosphate (LFP) batteries, especially in China – has driven energy storage system costs down, fueling a record 330 GWh of battery energy storage system (BESS) shipments in 2024. Edward Rackley, head of the energy storage team at Business intelligence specialist CRU, shares his analysis.

French energy cooperative Solarcoop has launched a solar router that redirects surplus photovoltaic power from self-consumption systems to electric water heaters or other resistive loads, and can also control additional devices such as heat pumps.

As a prototype, the Blatchford Lands virtual power plant (VPP) launches with 100 Sonnen batteries across the community, providing nearly 0.5 MW of power and more than 2 MWh of storage capacity to support the Canadian energy grid.

Anker Solix has launched the F3000, a 3.1 kWh portable power station with 3.6 kW output, dual solar inputs, and EV and generator charging. The system is expandable to 12.3 kWh and priced at $2,599 in the United States and Canada.

Evert has unveiled technical and availability details of its new power management unit, a wallbox that integrates a 22 kW bidirectional DC electric vehicle charger, a 20 kW PV inverter, and a home energy management system. The Norwegian startup targets residential users seeking integrated EV and solar energy solutions.

The Indian government has announced viability gap funding (VGF) of INR 54 billion ($631.5 million) to support 30 GWh of battery energy storage systems (BESS), allocating capacity among 15 states and the state-owned power producer NTPC. The scheme provides INR 1.8 million/MWh and requires projects to be commissioned within 18 months through competitive bidding.

US solar developers Soltage, Origis Energy, and rPlus Energies have secured more than $1 billion in financing across three major deals, signaling sustained investor confidence in utility-scale solar and storage despite US policy uncertainty. The transactions back more than 1.4 GW of solar and 1.8 GWh of battery capacity.
