The global shift towards decarbonization is no longer a choice but a necessity. As China's leading solar hybrid energy storage factory, we provide the infrastructure required to bridge the gap between intermittent renewable generation and 24/7 power demand. Our solutions align with the latest REPowerEU and Inflation Reduction Act (IRA) standards.
Commercial and Industrial (C&I) sectors are rapidly adopting hybrid storage to mitigate rising electricity costs and peak demand charges. Our high-voltage liquid-cooling ESS (Energy Storage Systems) provide unparalleled safety and energy density, ensuring a ROI of less than 5 years in most high-tariff regions.
Hybrid storage acts as a "Shock Absorber" for the grid. By integrating advanced Virtual Power Plant (VPP) capabilities, our systems allow users to participate in frequency regulation and demand response, turning a passive storage unit into an active revenue-generating asset.
Established in 2014 in the heart of China's Silicon Valley, Shenzhen Suntherra Battery Co., Ltd. has spent a decade refining the science of electrochemical storage. Our 12,000 square meter facility isn't just a factory; it's an innovation hub where 180+ specialists work on the next generation of LiFePO4 technology.
As a premier OEM/ODM supplier, we specialize in:
While LiFePO4 remains the gold standard for safety, we are currently piloting Solid-State Battery prototypes and Sodium-Ion alternatives for extreme cold-climate applications, aiming for a 2026 commercial rollout.
Our upcoming 2.0 EMS (Energy Management System) utilizes machine learning to predict weather patterns and local grid price fluctuations, automatically optimizing charge/discharge cycles for maximum economic gain.
Sustainability is core to Suntherra. We are implementing a "Second-Life" program where degraded C&I batteries are repurposed for less demanding residential backup, ensuring 95% material recyclability.
Navigating international regulations is the biggest hurdle for solar installers. Suntherra simplifies this with a robust compliance framework:
CE, TUV, EN62619 & VDE-AR-N 4105 Certification. Local warehouse in Germany/Poland.
UL1973, UL9540A & NEC 2020 Compliance for seamless permitting and utility interconnection.
Ruggedized IP65 designs optimized for high-temperature and weak-grid environments.
DDP Shipping options and UN38.3 certified dangerous goods packaging for air/sea freight.
Designed for households with high solar generation but low daytime usage. Store excess midday sun and power your home through the night, reducing grid reliance by up to 90%.
In regions with unstable grids, our 10ms seamless switching ensures that computers, medical equipment, and security systems never lose power during an outage.
Perfect for telecommunications towers, remote mining sites, or island resorts where diesel fuel logistics are prohibitively expensive. A hybrid system provides clean, silent, and maintenance-free power.
DC-coupling is more efficient for new installations as it charges the battery directly from solar panels via a charge controller. AC-coupling is ideal for retrofitting existing solar systems, as it allows the battery to be added to the AC output side of the current inverter.
Most of our LiFePO4 cells are rated for 6,000+ cycles at 80% Depth of Discharge (DoD). In a typical daily cycle scenario, this equates to 15-20 years of operational life, significantly outperforming lead-acid (2-3 years) and standard NCM lithium (5-7 years).
Technically difficult and not recommended. Communication protocols between the BMS and the Inverter (via CAN/RS485) must be perfectly synchronized. At Suntherra, we provide pre-configured "Stackable" kits to ensure 100% compatibility.
For high-power C&I applications, yes. Liquid cooling ensures a uniform temperature across all cells (within ±2°C), which prevents thermal runaway and extends the battery lifespan by 20% compared to traditional air-cooled cabinets.
