SolarEdge 3PH Inverter, 25kW, MC4, DC safety unit with switch, AC & DC SPD, AC/DC Segregation, Inverters with SetApp configuration (SE25K-RW00IBNJ4) is a three-phase commercial inverter with three MC4 connectors.

The inverter is also equipped with a type 2 DC overvoltage protection and a Surge Protection Device (SPD). In terms of communication, two RS485 ports and one Ethernet connection are integrated. It is possible to connect to the inverter via wifi. However, a separate antenna is required for this. The SolarEdge SetApp can then be used for commissioning and monitoring.

Communication

A connection via RS485 is possible via two ports which are standard in the inverter. There is also an Ethernet port. It is possible to use a wi-fi network, but this requires a separate antenna.

Security

Arc protection, leakage current and overvoltage protection are all present. Electric arcs are not uncommon. For example, they occur during normal use of switches and plugs. Arcs that take on certain proportions, for example due to defects, can be harmful or even result in fire. Leakage currents also occur. Often these are innocent and are disposed of without any problems. If a person comes into contact with a certain component that experiences leakage currents, this can result in dangerous situations. The leakage current protection ensures that the system switches itself off within 20 to 40ms as soon as a person comes into contact with the circuit. This prevents electrocution.

DC safety unit with switch

The supplied DC safety unit with switch is located underneath the inverter. This switch is a two-pole DC switch. This ensures that both the neutral and the phase wire are interrupted, so that the entire system will be free of power. The SPD will protect the system against overvoltage caused by lightning strikes, for example.
