PRODUCT IDENTIFICATION
The Grid-Tied Inverter (Model: GTX-1500-HV) serves as the core bi-directional power conversion hub for modern utility-scale and commercial energy storage systems. Designed for seamless grid interfacing, this inverter enables high-efficiency DC/AC conversion for photovoltaic storage, peak shaving, and frequency regulation applications.
INTERNAL BESS TOPOLOGY
The GTX-1500-HV employs a three-level NPC (Neutral Point Clamped) topology with SiC MOSFETs. This architecture minimizes switching losses while maintaining <3% total harmonic distortion (THD) under full load. The inverter integrates a dedicated DC-DC booster stage for PV string input (max 1500 V DC) and a bi-directional AC-DC stage for grid tie and islanding mode support.
THERMAL PROTECTION MECHANISMS
- Smart liquid cooling system maintains IGBT junction temperature below 85°C at 50°C ambient.
- Redundant fan assist for peak load transients >110% rated power.
– IP65-rated heat exchanger with condensation prevention.
OPERATIONAL ADVANTAGES
– Seamless switching between grid-following (PQ) and grid-forming (VF) modes (<20 ms transition) - Nighttime SVG (Static Var Generator) function for power factor correction from 0.8 leading to 0.8 lagging - Anti-islanding protection compliant with IEEE 1547-2018 - Black start capability with external generator synchronization SPECIFICATION MATRIX
