The MNPVHV series of combiners are manufactured for indoor / outdoor use and designed for combining high voltage strings using 10mm x 38mm fuses. The use of touch safe din rail mount fuse holders and fuses allow operation up to 600 Volts. The MNPV8HV and MNPV16HV are reconfigurable to accommodate non-isolated inverters or to divide one combiner into two separate halves to power 2 inverters.

This MNPVHV Combiner comes complete with all the busbars and additional labels required to reconfigure to any of the three configurations: Non-Isolated, 2 Inverter, and Parallel.
