Germany’s AEG has presented an AC-coupled, low-voltage storage system for residential applications.

The system was developed by Dutch companies BM Energy and Apex Power Supplies, with a focus on the requirements of the Dutch residential market. BM Energy is an importer, distributor and wholesaler of renewable-energy products for the residential and commercial sectors, while Apex Power Supplies is a Poeldijk-based distributor specializing in residential batteries and energy storage systems for installers and energy professionals.

“The Solarcube Pro is an extension of the existing AEG Solarcube range,” Govert Zaalberg, COO of BM Energy, told pv magazine.

According to the product datasheet, the Solarcube Pro is a storage system with 6.0 kWh of nominal battery capacity and 6.028 kWh of nominal battery energy. It uses lithium iron phosphate (LFP) cells.

The 6 kWh configuration consists of a 3 kWh base unit combined with a 3 kWh battery power module. AEG describes the product as a plug-and-play system designed for integration into residential properties.

The battery can charge and discharge at up to 3 kW. On-grid AC output is rated at 800 W as standard, with a 1,500 W “premium” setting. The manufacturer notes that activation of the premium function is subject to local regulations and should only be carried out by authorized personnel.

The system operates at a 90% depth of discharge, according to the datasheet, which states that the figure is based on testing at 25 C.

5 mm x 460 mm x 281 mm and weighs 54 kg. It has an IP66 enclosure and an operating temperature range of -20 C to 55 C.
