This part is made up of the following items: 1 x SE-WND-3Y400-MB-K1 1PH/3PH 230/400V SolarEdge Modbus Meter 1 second K1 1 x SE-ACT-0750-100 100A Split- Core Current Transformer 10 x RS485-1M Double pair genuine RS485 cable 1M – 4 cores This kit is a full monitoring package for Solaredge domestic systems that allows full recording and display of energy generation and usage. Ensures that the complete system is performing at its maximum potential and enables optimisation of energy consumption. Subject to the approval of your local DNO this package may be used to limit the power export of the system to a value agreed with the DNO. e.g. a 100kWp PV system with 85kW of inverters could be limited to 75kW of AC export power if that is required by the DNO. During periods of self consumption, e.g. Monday – Friday, sufficient power is likely to be used by the property and so no limitation is applied but during high generation and low self consumption periods the system will automatically trim the maximum export power to a DNO defined limit. With most commercial buidings this ‘lost’ energy will be a very small percentage of the total annual generation and the benefit of having additional generation capacity most of the time will far outweigh the lost generation during other times. Note: This package includes an energy meter and 100A CT for a single inverter system. For a system with multiple inverters an additonal RS-485 expansion kit is required, which allows multiple inverters to be connected in a communication bus and also to the energy meter. A 10m length of RS-485 cable is included for connection between the inverter and energy meter, and for connecting the inverters in the bus. Please check if this quantity is sufficient. Supplied with 1 X 100A current monitoring clamps suitable for installation on properties with up to 100A per phase power supply. Current clamps should be sized according to incoming grid supply in the property, please check if these are sufficient before buying. Please note other CTs are available.
