Shenzhen Suntherra Battery Co., Ltd. stands as a premier beacon in the global renewable energy landscape. Since our inception in 2014 in the heart of China’s technological hub, Shenzhen, we have transitioned from a specialized battery assembly shop into a high-tech powerhouse specializing in Solar Energy Storage Systems (ESS). Our mission is to bridge the gap between intermittent renewable generation and reliable, 24/7 power availability.
Occupying a sophisticated 12,000-square-meter facility, Suntherra integrates advanced automation with human expertise. Our 180+ workforce includes veteran battery engineers and R&D specialists who focus on the "Information Gain" of energy density, thermal stability, and BMS (Battery Management System) intelligence. We don't just export products; we export reliability through rigorous quality control inspectors and international sales professionals who understand the nuances of global grid compliance.
Located in Shenzhen, we leverage the world's most mature lithium-ion supply chain. This allows us to source Tier 1 Grade A cells (like the 314Ah/280Ah variants) at competitive prices, ensuring that our OEM clients benefit from the latest innovations in chemical stability and cycle life.
Our ODM services cover everything from BMS communication protocol matching (CAN/RS485) with global inverters like Victron, Growatt, and Deye, to structural design for IP55-rated outdoor enclosures. We provide "Information Gain" by optimizing the weight-to-capacity ratio for residential Powerwalls.
Every LiFePO4 pack undergoes 100% EOL (End of Line) testing, including capacity grading, high-temperature aging, and safety discharge tests. This commitment allows us to offer industry-leading 10-year warranties on our premium lithium series.
The global shift toward decarbonization has transformed energy storage from a luxury to a critical infrastructure component. As a leading exporter, we observe three major shifts in the industry:
For markets like Germany and Australia with high electricity prices, our 5kWh/10kWh Powerwalls allow homeowners to store solar energy during the day and power their homes at night, achieving up to 80% energy independence.
Commercial and Industrial (C&I) clients in North America and Southeast Asia use our 215kWh containerized systems to shave peak demand charges and provide UPS-grade backup for manufacturing lines.
In remote regions of Africa and South America, our 48V rack-mounted LiFePO4 batteries provide reliable power for telecom base stations, replacing high-maintenance diesel generators.
For global enterprises and wholesalers, procurement is no longer just about the lowest price—it's about compliance, scalability, and technical support. Suntherra provides:
UN38.3, MSDS, CE, and UL-standard cell sourcing for seamless customs clearance.
Monthly capacity exceeding 50MWh to handle large-scale utility and C&I orders.
Full white-label OEM services including custom UI for monitoring apps and casing aesthetics.
Specialized DG (Dangerous Goods) shipping networks for worldwide door-to-port delivery.
Our premium LiFePO4 cells are rated for over 6,000 cycles at 80% DOD (Depth of Discharge) under 25°C. This translates to roughly 15 years of daily use in a typical solar storage environment.
Yes, our BMS supports CANbus and RS485 communication protocols. We have pre-configured compatibility with SMA, Victron, Deye, Goodwe, Growatt, and Must inverters.
For standard samples, the lead time is 7-10 days. For bulk OEM orders (e.g., 500+ units), the typical lead time is 25-35 days depending on the customization requirements for the enclosure and BMS firmware.
Absolutely. Our hybrid solar LiFePO4 systems are designed to work in both scenarios, providing seamless grid-tie-back and robust off-grid islanding capabilities during power outages.
Our 215kWh+ commercial systems feature integrated fire suppression (FM200 or Aerosol), active liquid cooling/air cooling thermal management, and multi-level BMS protection (cell, pack, and cluster level).
