FAQ

1. What sets Ruisu apart in the Energy Storage System (ESS) market?
 
We are a premier provider of utility-scale and C&I (Commercial & Industrial) energy storage. Our flagship 3MW Mega-Watt BESS is engineered for high-capacity energy management, offering industry-leading energy density and safety. Backed by 120 R&D experts, we deliver complete "PV-Storage-Charging" integrated systems that allow clients to maximize energy efficiency and grid stability.
 
2. Can your BESS and charging systems handle industrial-grade heavy loads?
 
Yes. Our equipment is built for the most demanding applications. We specialize in high-power infrastructure, including:
3MW Storage Cabinets: For peak-shaving, load shifting, and backup power.
1200kW Liquid-Cooled Ultra-Fast Chargers: Capable of powering construction machinery, mining trucks, and port vessels that require massive energy throughput in minimal time.
 
3. How do you ensure the safety of your high-capacity storage and chargers?
 
Safety is our top priority. Our systems feature:
 
Multi-Layered Protection: Integrated BMS (Battery Management System) with real-time monitoring of voltage, current, and temperature.
Advanced Cooling: Our proprietary Liquid-Cooling technology prevents thermal runaway and maintains peak performance even during high-ambient temperature operations.
Certifications: All products are fully CE, UL, CB, and FCC certified, meeting the rigorous safety standards of North America and Europe.
 
4. Are your energy solutions adaptable to extreme environments?
 
Absolutely. Ruisu products are "All-Terrain Reliable." Our energy storage and charging units are deployed in environments ranging from -45°C extreme cold regions to high-altitude mines and high-humidity ports. We use industrial-grade components and specialized synthetic coolants to ensure 24/7 uptime regardless of the climate.
 
5. Do you support customized OEM/ODM projects for energy storage?
 
Yes. With an 80,000 m² manufacturing base and a vast portfolio of 180+ patents and intellectual property rights, we offer highly flexible customization. We can tailor the capacity (from kW to MW), branding, software integration (SOA-based SaaS), and connector standards (CCS1, CCS2, NACS, GBT) to fit your specific regional or project requirements.

6. How does your "PV-Storage-Charging" integrated solution work?
 
Our integrated system combines photovoltaic (solar) power generation, high-capacity battery storage, and EV charging into a single smart ecosystem. This allows you to store solar energy during the day and discharge it for ultra-fast charging or peak-shaving, significantly reducing operational costs and your carbon footprint.
 
7. What kind of support can I expect after purchase?

We provide 24/7 global technical support and comprehensive after-sales service. Because we control the full industry chain—from research to manufacturing—we can provide rapid response times, firmware updates, and high-quality spare parts to ensure your infrastructure remains future-proof.
