PV Guided Tours: Atmoce is introducing a 25-year warranty on its residential storage system and unveiling intelligent module-level energy management that supports automated snow clearing of solar panels. On the storage side, the portfolio is being expanded with the C&I BattBank, the first AC-coupled, stackable commercial storage system designed for low-voltage operation.

May data from sun.store show a broad price decline across residential battery segments, reversing part of the April increase in the performance category. In the commercial segment, pricing remained broadly stable.

The new Sunenergyxt 500 brings together rooftop solar integration, variable pricing models and standalone capability, giving installers and end users a flexible building block for residential and small commercial sites.

PV Guided Tours: Homes are increasingly becoming energy producers. Sector coupling within the building is growing in importance and even electric vehicles are now part of the picture. Gregor Kuschmann and Robert Pawlik of Solarwatt explain which components and solutions make energy independence possible and how buildings are playing a new role in the energy market.

The Industrial M offers up to 904 kilowatt-hours of capacity in a compact 10-foot all-in-one design built around new electric-vehicle batteries.

Varta brings together inverter, high-voltage battery and energy management in its Hybridwall unit, in a compact, integrated format for residential and small commercial use.

An analysis from the University of Zagreb sets out how a mix of storage and flexibility options, from pumped hydro to bidirectional EV charging, could underpin Croatia's renewable energy transition.

Sensors, extinguishing systems and pressure relief packaged into a single technical container can simplify planning, speed permitting and give emergency services a clear point of intervention.

At Intersolar Europe 2026, BLUETTI showcased its commitment to home energy independence through an open energy ecosystem integrating balcony solar solutions, residential energy storage and smart energy management. 

Lithium-ion storage carries real risks of thermal runaway, fire and explosion. Certified technical containers can shield installations from external hazards and ease the route through building approval processes.

Built on LFP cells and compatible with the earlier series, the Ocean 2 offers three-phase storage for residential use, scalable to twelve modules and equipped with whole-house backup power as standard.

With 15.4 kW continuous and 21 kW peak AC output, the 3P brings three-phase capability to households running heavier loads.

New figures from UNEF show installed storage capacity for self-consumption rose by 65 percent last year, with residential deployments nearly doubling as battery costs continue to drop.

Each 197 kWh cabinet pairs with one or two 50 kW battery inverters and can be scaled modularly, reaching up to 1 MW of power and 4 MWh of storage per installation.

Podcast: The Energy Center from ESS Inc. in Oregon is an iron flow storage system offering 1.16 MWh of capacity and 174 kW of maximum charging power. Housed in a single container, the modular unit is designed for a range of commercial and grid applications. Alan Greenshields, Director EMEA at ESS, discusses long-duration storage and the role of redox flow technology using sustainable materials such as iron, salt and water.

That energy storage is needed is no longer in question. What matters now is the system it forms together with generation, controllable loads and e-mobility, as Philipp Rasche of ENEO explains.

Ja Planet and Ja Galaxy, the manufacturer's two new lithium iron phosphate systems, cover applications from commercial and industrial sites up to large-scale grid-connected projects.
