High-Efficiency Energy Storage Inverter Series Debuts
Targeting Distributed PV Market with Advanced Flexibility
MUNICH, Germany – August 6, 2025 – A new line of high-performance energy storage inverters designed for distributed photovoltaic (PV) systems was unveiled today, offering a blend of industry-leading efficiency, versatile battery compatibility, and robust grid integration capabilities. The series, which includes five models spanning 12kW to 30kW nominal AC output, is engineered to meet the growing demand for reliable, scalable solar energy storage solutions in residential and small commercial settings.
Industry-Leading Efficiency Drives Energy Savings
At the core of the series is its exceptional power conversion efficiency. The top-tier model achieves a maximum PV-to-AC efficiency of 98.4%—one of the highest in the market—with a weighted efficiency (PVOUT) of 98.2% for consistent performance across varying loads. This efficiency is paired with a wide maximum power point tracking (MPPT) voltage range of 160-950V, enabling compatibility with diverse solar panel configurations and maximizing energy harvest even in low-light conditions. Each inverter features 2 to 3 MPPT trackers (depending on the model), with a maximum input current per tracker of 40A, ensuring optimal performance for partially shaded arrays.
Flexible Battery Integration for Expanding Needs
A key differentiator is the series’ support for both lithium-ion and lead-acid batteries, with a battery voltage range of 190V to 800V (model-dependent). The inverters deliver high charge/discharge currents—up to 45A for the 30kW model—and can connect up to three battery ports (for select variants). When dual ports are used, the maximum charge power reaches 45kW, catering to users looking to scale their storage capacity over time. This flexibility makes the series suitable for everything from home backup systems to commercial applications requiring uninterrupted power.
Robust Output and Backup Capabilities
On the AC side, the inverters deliver nominal power from 12kW to 30kW, with a maximum output power (PF=1) of up to 33kW. The backup power (THDU) function ensures seamless operation during grid outages, with nominal output matching the main AC power and peak apparent power (5-minute) reaching 45kVA. This makes the series ideal for critical loads such as medical equipment, retail stores, or entire residential properties.
Safety and Compliance at the Forefront
Safety features include Class I protection classification, anti-islanding protection, and a suite of overcurrent/overvoltage safeguards for both AC and DC circuits. Surge arresters (DC Type II, AC Type III) and insulation resistance detection further enhance reliability, while compliance with international standards like IEC 62109-1/2, VDE 4105, and EN 50591 ensures adherence to stringent grid codes.
Intelligent Design for Modern Energy Systems
The inverters are equipped with a user-friendly interface, including a Bluetooth-connected mobile app, LED indicators, and an optional LCD display. Communication interfaces such as RS485, CAN (for battery management system integration), and optional Wi-Fi/LAN enable seamless connectivity with smart grids, energy meters, and home automation systems. A compact form factor (660mm×596mm×235mm) and lightweight design (45kg to 55kg) simplify installation, while natural or smart fan cooling ensures optimal performance in temperatures ranging from -25℃ to 60℃.
Industry Praise for Versatility and Reliability
“The series strikes a perfect balance between efficiency, flexibility, and safety—key factors for homeowners and businesses looking to invest in solar storage,” said a senior analyst at a leading clean energy research firm. “Its ability to support multiple battery types and scale with growing needs positions it as a strong contender in a crowded market.”
Shipments are expected to begin in Q4 2025, with the inverters backed by a comprehensive warranty aligned with industry standards. The series is already generating interest from installers and distributors, who cite its compatibility with global grid codes and ease of integration as major selling points.
As the world shifts toward decentralized energy systems, this inverter series is poised to play a critical role in helping users maximize their solar investments while ensuring reliable, sustainable power.
