Altech PV protection components are built to help safeguard key parts of a solar power system, from the DC string side through the inverter and out to the grid connection. gPV fuses are designed to protect cables and PV modules against reverse overcurrent, helping isolate a faulted string so the rest of the array can keep producing power.

• DC circuit protection, including overvoltage protection and reverse current protection
• DC to AC inverter circuit protection, including semiconductor protection
• AC circuit protection between the inverter and the power grid, including overvoltage, overcurrent, and anti-islanding protection
• Product options include cylinder fuses, fuse holders, NH-type fuses, fuse bases, and fuse disconnectors
• For arrays with three or more strings in parallel, positive string fusing helps protect conductors and PV modules from damage
• If an inverter fails, AC reverse current can feed into DC strings, and PV fusing helps reduce the risk of module damage
