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.
