EV PV fuse market demand and melamine tube selection

High-voltage protection fuse is mainly applied to new energy vehicles, the application voltage is generally 60VDC-1500VDC, mainly power fuse (new energy vehicle high-voltage fuse) for the protection of the main circuit and auxiliary circuit. New energy high-voltage protection single vehicle requires the configuration of 6-8 sets of fuses

Photovoltaic field: at present the voltage used is mainly 1,500VDC and 1,000VDC. in 1,500VDC photovoltaic system, each 1MW installation, the sink side with about 150-180 sets of fuses, each set of unit price of about 20 yuan; inverter side with about 4-8 high current fuses, each unit price of about 250 yuan, according to this estimate, the amount of fuses used in each 1MW installation is about 4 Accordingly, it is estimated that the amount of fuses used per 1MW installation is about 4,000-5,600 yuan. In 1,000VDC photovoltaic system, each 1MW installation, the sink side with about 320-400 sets of fuses, each set of unit price of about 10-12 yuan; inverter side with about 8-12 high-current fuses, each unit price of about 150 yuan, but 1,000VDC photovoltaic system in part of the inverter side of the protection program using circuit breakers instead of fuses, it is estimated that each 1MW installation with fuses The amount is about 3,800-5,700 yuan.

Wind power sector: for each 1.5-2MW installation, about 6 fuses for AC output, 3-6 fuses for auxiliary transformer, 3-6 fuses for lightning protection, 3-6 fuses for measurement circuit, 4-6 fuses for control circuit, and some systems also use 2-4 DC fuses, so it is estimated that the amount of fuses used for each 1.5-2MW installation is about 4,000-6, 000 yuan

Each 1GW energy storage system uses about 6,000-10,000 main fuses and about 30,000-5,0000 internal fuses, so it is estimated that the amount of fuses used per 1GW installation is about 10-14 million yuan

Currently, we are the designated supplier of melamine tubes for LITTELFUSE, BUSSMANN, CFL and HOLLYTECH. We believe that wellele’s  fuse tubes are the best choice for your EV FUSES, PV FUSE and other applications.
