Application Solutions

Sinofuse (Zhongrong) provides high-voltage DC circuit protection solutions for new energy industries: 1) Electric Vehicles - battery pack protection, motor drives, onboard chargers, and DC/DC converters with fuses rated up to 1000VDC

2) Battery Energy Storage Systems (BESS) - utility-scale and commercial storage with 1500VDC protection

3) Solar Power - photovoltaic inverters, combiner boxes, and DC distribution with gPV-certified fuses

4) Industrial - power distribution, motor protection, and control systems. Each solution leverages Sinofuse's expertise in high-voltage DC protection with ratings up to 100kA breaking capacity.

Identify your industry and system voltage requirements, then explore our industry-specific solutions or contact our FAE team.

Voltage rating selection depends on system architecture: 1) 500VDC - suitable for low-voltage commercial EV and small energy storage systems

2) 750VDC - common for passenger EVs and medium-scale storage

3) 1000VDC - standard for modern EV platforms and large commercial storage

4) 1500VDC - used for utility-scale solar and energy storage to reduce DC cabling costs. Consider future expansion - many systems are migrating to higher voltages. The fuse voltage rating must exceed maximum system voltage including transients. Contact our FAE for system-specific recommendations.

Select voltage rating 20% above maximum system voltage. Consider industry trends toward higher voltages.
