Technical FAQ — HNPM Battery Solutions
Q1: What certifications do HNPM battery systems carry?
All HNPM products are certified to global standards including UL 1973 (stationary storage), CE (European conformity), UN38.3 (transportation safety), IEC 62619 (secondary lithium cells), and ISO 9001:2015 (quality management). Specific certifications vary by product line — contact our engineering team for compliance documentation.
Q2: Can HNPM provide OEM/ODM battery solutions with custom branding?
Yes. Our 30,000 sqm facility supports full OEM/ODM services including custom cell configurations, proprietary BMS programming, enclosure design, and third-party certification coordination. MOQ and lead times are discussed during the RFQ consultation.
Q3: What is the cycle life of your LFP energy storage systems?
HNPM's LiFePO4 (LFP) BESS modules are rated for ≥6,000 full cycles at 80% Depth of Discharge (DoD), with a capacity retention of ≥80% at end-of-life. This translates to a design life of 15–20 years under daily cycling conditions.
Q4: Why does HNPM offer both Ni-MH and Lithium chemistries?
Different applications demand different electrochemistries. Our Ni-MH series excels in safety-critical, high-temperature, and long-standby scenarios. Our LFP and LiPo series cover residential storage, C&I BESS, and high-rate UAV applications.
Q5: What is the operating temperature range for your industrial Ni-MH batteries?
HNPM's industrial Ni-MH series operates from -40°C to +90°C, making it suitable for Arctic installations, desert telecom towers, and industrial environments. Standard LFP systems operate from -20°C to +60°C with active thermal management.
Q6: How does HNPM ensure battery safety during international shipping?
All HNPM batteries are UN38.3 certified, covering altitude simulation, thermal testing, vibration, shock, external short circuit, overcharge, and forced discharge testing. Our Ni-MH series also carries non-hazmat classification advantages for air freight, reducing international logistics costs by 20–40% compared to equivalent lithium systems.
Q7: Can your systems integrate with existing solar inverters?
Yes. HNPM BESS systems support RS485, CAN, and RS232 communication protocols, compatible with Deye, Victron, SMA, Growatt, Huawei, and Solis inverters. Engineering integration support is available upon project inquiry.
Q8: What is the minimum order quantity for OEM projects?
MOQ varies by product line. For standard Ni-MH cells, MOQ starts from 10,000 pcs/SKU. For custom LFP BESS modules, project-based MOQ typically starts from 50kWh. Contact via WhatsApp (+86 13762272227) for consultation.
