NESP Rack Series

The 10,000-cycle rating is at 0.2C discharge rate and 80% DoD at 25°C. At higher discharge rates or deeper DoD, cycle life will be lower. As a reference: at 1.0C discharge (sustained), expect approximately 5,000–7,000 cycles at 80% capacity retention. At 2.0C peak (10-second pulse pattern), cycle life is not significantly affected relative to 1.0C sustained. Temperature below 15°C or above 45°C will accelerate capacity fade — contact engineering for derating curves specific to your site conditions.

We cannot provide tax advice. The NESP Rack Series meets the technical specifications commonly required for standalone storage ITC qualification under the Inflation Reduction Act (Section 48E): it is a rechargeable battery with a rated capacity of ≥ 5 kWh and a cycle life rating of ≥ 500 cycles. UL 1973 certification documentation is available for your tax advisor. We recommend consulting a qualified tax professional with the UL certification file and product datasheet to confirm qualification for your specific project structure.

Standard warranty: 10 years or 4,000 cycles, whichever comes first, covering defects in materials and workmanship. Capacity warranty: ≥ 80% rated capacity within the warranty period at rated operating conditions. The warranty does not cover damage from improper installation, operation outside specified parameters, or modifications to the BMS firmware. Extended warranty terms available — contact our commercial team for warranty program details for your application.
