WHES Strengthens German Energy Storage Expansion with PC-G2 Supply to Tesvolt
March 24, 2026 – WHES Energy Storage Systems announces the supply of its PC-G2 commercial & industrial battery energy storage system (250kW / 500kWh) to German provider and system integrator Tesvolt AG. The solution will support the launch of Tesvolt’s new storage offering for commercial, industrial, and smaller utility-scale applications across Europe.
The PC-G2 system combines WHES’s fully integrated storage architecture - including LFP battery technology, integrated inverter design, and advanced multi-layer safety features -with Tesvolt’s proprietary control and cybersecurity software. Together, these technologies enable the delivery of high-performance energy storage solutions with enhanced economic value for project developers and end users.
Strengthening Market Access Through Strategic Cooperation
As energy storage adoption accelerates across Europe, collaboration between global technology manufacturers and local system integrators is becoming increasingly critical to enable faster project deployment and optimized system performance. Supported by WHES’s distribution partner BayWa re, the partnership is well positioned for long-term growth.
“WHES is focused on delivering scalable and reliable storage solutions that help our partners respond to rapidly growing demand for flexible energy infrastructure,” said Bernd Haberecht, Sales Director DACH at WHES. “Working with experienced companies such as Tesvolt allows our PC-G2 system to be deployed efficiently in local markets while ensuring strong technical performance, safety, and project profitability.”
Designed for real-world commercial and industrial applications
The PC-G2 energy storage system is part of WHES’s commercial storage portfolio already deployed in more than 1,000 projects worldwide. The outdoor solution uses LFP battery cells from CATL, features a fully integrated inverter, and supports simplified installation and commissioning.
Engineered for demanding environments, the system meets corrosion protection class C5, making it suitable for coastal and industrial locations. It operates within an ambient temperature range of –20°C to +55°C and complies with key European grid standards including VDE-AR-N 4110.
A multi-stage safety concept combining active and passive fire protection measures ensures reliable long-term operation across applications such as peak shaving, energy arbitrage, dynamic tariff optimization, and multi-use strategies.
Deliveries of PC-G2 systems for Tesvolt projects are expected to begin in May 2026.
