Hill Tech is an emerging leader in Photovoltaic technology. Our special PV Fuses enable you to protect various aspects of your PV power generation. This can be a string inverters, central inverters or even the modules directly to protect your circuits in combiner boxes. Use of these fuses range from free-standing solar farms, which have high ambient temperatures requirements, to residential installations, where compact size is important.
Our specially developed fuses for photovoltaic systems trip reliably and in the case of minor over currents do not trip prematurely. We have a broad range of products suited for DC voltages as high as 1500 V. This covers almost all of the requirements for PV based power generation.
These Photovoltaic fuses come in small packages while maintaining the necessary critical high voltage rating. Cylindrical shapes range from 6.3 x 32 mm to 20 x 127 mm, and different NH sizes.
We are constantly expanding our product range focused on PV applications. Contact us for the solution that is just right for you!
