The latest renewable energy news includes announcements on Sungrow, JA Solar, Fibocom, Teraco’s 120 MW Sediba solar project in Parys, and others.
Sungrow Launches PowerStack 3.0 Battery Storage with 99.2% Efficiency and 43% Smaller Footprint
Sungrow has launched PowerStack 3.0, a commercial and industrial battery energy storage system delivering maximum power conversion efficiency of 99.2 percent and round-trip efficiency exceeding 92 percent. The system uses 684 Ah battery cells and offers energy density up to 256 kWh/m². For a 5 MWh installation, the required footprint is 43 percent smaller than the previous generation. Up to 20 units can operate in parallel. The system supports temperatures from −30°C to 50°C and delivers zero-millisecond grid-to-off-grid switching. Sungrow’s Bubbly AI assistant completes system design in 30 seconds and commissioning in three minutes. AI-optimized dispatch can increase returns by more than 12 percent compared with conventional self-consumption operation.
JA Solar to Supply Modules for Teraco’s 120 MW Solar Project in South Africa
JA Solar has been selected as the exclusive photovoltaic module supplier for Teraco’s 120 MW Sediba solar project in Parys, Free State province, South Africa. The project is expected to generate more than 354,000 MWh of renewable electricity annually, with commercial operations scheduled to begin by the end of 2026. JA Solar will supply high-efficiency n-type photovoltaic modules designed for high temperatures, intense solar irradiation, dust and hail exposure. Electricity generated by the project will enter South Africa’s national grid, with corresponding renewable energy allocated to Teraco’s data centres through power-wheeling agreements involving Eskom and local municipalities. The announcement did not disclose the module supply contract value or the number of panels ordered.
Fibocom Introduces 450 MHz LTE and 5G RedCap Connectivity for Smart Energy Systems
Fibocom showcased its smart energy connectivity portfolio at Enlit Europe 2026, including 450 MHz LTE and 5G RedCap modules for smart meters, solar inverters, EV chargers and battery management systems. Its LTE portfolio includes LE270, L610, NL668 and L716 modules, alongside MA510 and MQ771 low-power IoT modules. Selected MA510 and RU311 variants support 450 MHz LTE connectivity for private utility networks. Fibocom also presented RU311 and FG132 5G RedCap modules, with the RU311 LGA version designed for pin-layout compatibility with FG132 and NL668/L716 LTE Cat.4 module families. The company supported GridCrest’s ME260 single-phase smart meter development through firmware integration, operator-network testing and customized network-status functionality.
