The secondary protection device should operate in a Normally Closed (NC) mode. In a normally closed circuit, power flows until the relay is activated which disconnects the circuit and interrupts the power; the circuit is connected and the power returns when the relay is deactivated. CAUTION!
In the case of a solar system, the load is the home or business that the solar array is powering and the alternate power source is the grid or grid generator. The transfer switch function is to ensure the continued supply of power to electrical loads.
You can use these switches in different solar systems, as explained below. A grid-tie solar transfer switch is specifically used with a grid-tied solar power system. That means it allows your system to draw power from the grid when necessary, such as during bad weather.
relays. You can connect up to 15 inverters to one secondary protection device. For sites with more than 15 inverters, use multiple devices. The total length for all inverter wiring cannot exceed 200m. Total length of cable includes: Inverter-to- inverter cables. Inverter-to-secondary-protection-device cables.
There is a simple approach to defining primary and secondary windings for PV systems, and it comes from the physics of energizing a transformer. A transformer is energized when an initial inrush of current propagates in either the inner or outer coils.
Connect a wire from the secondary protection device to the RRCR. Connect wires from the L1 pin of this inverter to the L1 pin of the next inverter and so on. The RRCR needs to be connected to the communication leader inverter. Connect wires from the G pin of one inverter to the G pin of the next inverter and so on.
