Description DC combiner boxes are for connecting parallel PV strings into your MPPT. The box includes several features that reduces the amount of separate components you need to install. The box offers isolation between the DC voltages that are generated by the PV modules and the solar installation allowing for safety while working or maintaining the system. With fusing and short circuit protection the PV modules and components can operate optimally with lightning protection included. Combining multiple series strings from the PV modules the unit allows for a single parallel connection to the MPPT charge controller. Positive and negative poles of each PV string are equipped with special fuse wire, which protects the PV string from fault. It also uses matchable fuse holder and fuse wire to reduce later maintenance cost and guarantee safety The unit uses photovoltaic HV lightning protector to carry out protection to the positive pole-to-ground and negative pole-to-ground of bus after combination. Surge / Lightning Protection. Isolation of PV DC voltages. Fuse Protection. DC Breakers
