    SolarEdge Power Management package <100A grid supply

    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.

    Solaredge Power management package for up to 250A grid supply

    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.

    Grid electricity prices are constantly on the rise. This is a motivation to install large PV systems that allow owners to minimize consumption from the grid during the day. However, some DNOs limit the amount of PV power that can be fed ­in to the grid or allow no feed ­in whatsoever, while allowing the use of PV power for self­ consumption.

    SMA Power management package for systems up to 63A/phase grid

    This part is made up of the following items:
    1 x HM-BT-10 SMA Sunny Home Manager with Bluetooth
    1 x EMETER-20 SMA Energy Meter 3 phase (<63A)
    1 x CAT5E-10M Cat 5e Terminated RJ45 Ivory Shielded – 10m
    1 x CAT5E-3M Cat 5e Terminated RJ45 Ivory Shielded – 3m
    This kit is a full monitoring package for SMA commercial systems that allows full recording and display of energy generation, usage and environmental conditions. 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 50kWp PV system with 48kW of inverters could be limited to 40kW 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.

    2x CAT5 cables are supplied, shorter 3m for connection between inverter and Home Manager and longer 10m for connection between Homemanager and meter. Please check if these lenghts are sufficient and source shorter/longer ones if required.

    Supplied WITHOUT current monitoring clamps, so it is only suitable for installation on properties with up to 63A per phase main AC supply.

    Current clamps (or Home Manager rating) should be sized according to incoming grid supply in the property (not size of the PV array), please check if these are sufficient before buying.

    Solar-Log Power Management Package <15kWp 100A supply

    Combine the Solar-Log 300 and the PRO380 energy meter to combine detailed monitoring with power management and export limitation small three phase installations.

    The PRO380 uses CTs to accurately read the current from the supply cable. The package includes three CTs rated at 100A, but you should check to make sure that is sufficient and swap to a higher rated version if neccessary.

    Current clamps should be sized according to incoming grid supply in the property, please check if these are sufficient before buying. Please note larger CTs are available.

    2x CAT5 cables are supplied, shorter 3m for connection between inverter and Solar-Log 300 and longer 10m for connection between Solar-Log 300 and Modbus meter. Please check if these lengths are sufficient and source shorter/longer ones if required.

    This part is made up of the following items:
    1 x HM-BT-10 SMA Sunny Home Manager with Bluetooth
    1 x EMETER-20 SMA Energy Meter 3 phase (<63A)

    This kit is a full monitoring package for SMA commercial systems that allows full recording and display of energy generation, usage and environmental conditions. 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 150kWp PV system with 140kW of inverters could be limited to 125kW 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 othecr times.

    2x CAT5 cables are supplied, shorter 3m for connection between inverter and Home Manager and longer 10m for connection between Homemanager and  meter. Please check if these lenghts are sufficient and source shorter/longer ones if required.

    Supplied with 3 X 200A current monitoring clamps suitable for installation on properties with up to 200A per phase AC suppiy.
