The ComAp MainsPro solar protection relay is used for grid-tie applications, and provides anti-islanding protection as required by Distribution Network Service Providers for solar over 30 kW. It can be used with any embedded generator systems such as gen sets, co-generation, or renewable energy sources including photovoltaic plants or wind turbines. The ComAp MainsPro grants adjustable voltage, frequency, and loss of mains functions to safeguard the distribution network and the generators.
With ComAp MainsPro, no special knowledge is needed for the installation process and no additional units are required. This makes it an optimal solution for both untrained personnel and professionals. The unit is designed to comply completely with Utilities’ connection requirements and statutory codes, offering a high level of protection and safety when working in parallel to the mains.
This item can be used within our secondary protection units which come as a switchboard ready to connect inverter cabling to.
The ComAp MainsPro complies with IEC 60255, G83, G59/3, UL508, CEI 0-21, IEn NR 005/2012, VDE V 0126-1-1 and VDE-AR-N 4105
