Part No: HUAWEI-PWR-MGMT-250A-UK Power Management - Export Limitation 3ph This part is made up of the following items: 1 x HUA-SL_3000A Huawei Smart Logger 3000A   1 x DTSU666-H-3PH-250A Huawei DTSU666-H Three Phase Energy Meter with 3x 250A CT   Huawei Export Control Solution measures the active power at the point of connection to the distribution system, and then uses the information to control the inverters output power and balance the customer demand in order to control the export power to the distribution system for not exceeding agreed export capacity.  This system complies with UK G100 regulations with regards to reaction times and fail-safe functionality. This package is required for multiple Huawei inverters per site. Single inverter systems can limit export using DTSU666-H-3PH-250A meter only. Please note current clamps should be sized according to incoming grid supply in the property (not size of the PV array), please check if these 250A CTs are sufficient before buying.  Weight: 4.8 kg

Part No: SE-PM-WND-3PH-250A Power Management - Export Limitation 3ph This part is made up of the following items: 1 x SE-WND-3Y400-MB-K2 1PH/3PH 230/400V SolarEdge Energy Meter K2 with Modbus Connection   3 x SE-CT-SPL-250A-A 250A Split-Core Current Transformer for SolarEdge Energy Meters with Modbus Connection   20 x RS485-DOUBLE-1M Double pair genuine RS485 cable 1M - 4 cores Price per Meter   This kit is a full monitoring package for SolarEdge commercial 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 buildings 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 kit includes 1x RS485 Expansion Kit, which means its only suitable for systems with 2x inverters. If more than 2x inverters on site additional RS485 Kit per inverter will be required, if only one inverter on site this part will not be required.  A 20m length of RS-485 cable is included for connection between the first inverter and energy meter, and for connecting the inverters in the bus. Please check if this quantity is sufficient. Supplied with 3 X 250A current monitoring clamps suitable for installation on properties with up to 250A 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 smaller CTs are available.   Weight: 2.76 kg

Part No: SE-PM-WND-1PH-100A Power Management - Export Limitation 1ph This part is made up of the following items: 1 x SE-WND-3Y400-MB-K2 1PH/3PH 230/400V SolarEdge Energy Meter K2 with Modbus Connection   1 x SE-CT-SPL-100A-A 100A Split-Core Current Transformer for SolarEdge Energy Meters with Modbus Connection   10 x RS485-DOUBLE-1M Double pair genuine RS485 cable 1M - 4 cores Price per Meter   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.

Note:  This package includes an energy meter and 100A CT for a single inverter system. For a system with multiple inverters depending on inverter type, an additonal RS-485 expansion kit might be required.  This 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.   Weight: 1.46 kg
