NPS01-F40-DC1500 2+MP Surge Protective Device
Product Overview
Tailored for next-generation 1500V utility-scale solar farms and grid-tied battery storage facilities, the NPS01-F40-DC1500 2+MP Surge Protective Device provides uncompromising transient protection under high DC system voltages. Utilizing high-capacity varistor elements and a heavy-duty spark gap in a Y-topology, this NPS01-F40-DC1500 2+MP Surge Protective Device safely diverts 40kA surges while eliminating earth-leakage degradation. We manufacture this flagship model to protect 1500V PV string inverters, central inverter stations, and large-scale utility containerized BESS enclosures worldwide.
Application Scenarios
- 1500V Utility Solar Farms: String combiner boxes, centralized megawatt inverters, and floating PV arrays.
- Grid-Scale BESS: High-voltage containerized battery energy storage systems and DC switchgear.
- Solar-Storage Hybrids: Central DC coupling switchboards and renewable-powered industrial complexes.

FAQ
Q1: Why is a DC 1800V Uc rating critical for 1500V PV systems?
A1: Cold weather conditions cause open-circuit voltage (Voc) to rise substantially; DC 1800V Uc provides the necessary safety margin to prevent thermal failure.
Q2: What is your replacement warranty terms for utility projects?
A2: We provide a comprehensive 1-year replacement warranty, dispatching free one-to-one replacements within 3 business days, backed by lifetime cost-price service.
