Overview of the Energy Management Functions
Description | Energy Planner | Energy Maximizer | Sunny Home Manager 2.0 | |
|---|---|---|---|---|
Intelligent energy management | ||||
Increased self-consumption | System optimization based on PV generation and loads and the control of batteries and inverters to increase self-consumption. | ✓ | ✓ | ✓ |
Optimization of dynamic electricity tariffs | The algorithm determines and calculates the most cost-effective approach based on the tariff data. | ✓ | ✓ | ✓ |
| The energy management system charges the battery with power from the utility grid at an opportune time to save money. | ✓ | ✓ | ✓ |
| The battery feeds power into the utility grid, if permitted, to optimize the economic operation of the system. | − | ✓ | - |
| In the event of negative feed-in tariffs, the flow of electricity at the point of interconnection is regulated to avoid penalty payments. | − | ✓ | - |
Peak load shaving | Reduction of the maximum power consumption in the utility grid through battery discharge. | ✓ | ✓ | ✓ |
| Reduction of the maximum grid-supplied power through battery discharges or load reductions. | ✓ | - | - |
| The system determines how much energy needs to be reserved and adjusts accordingly, increasing the reserve if a high or long peak load is expected. | - | ✓ | - |
| Throttles the charging of electric vehicles to reduce grid-supplied power. The power will then be increased automatically. | ✓ | ✓ | ✓ |
Intelligent battery control | ||||
Optimization of the battery life | Charging to 100% will be kept as short as possible. | - | ✓ | - |
Oversizing on PV side | Takes into account that more PV power (DC) is connected to the hybrid inverter than it can convert on the AC side. The surplus energy generated as a result is put to good use by being used to charge the battery. | - | ✓ | - |
Charging the battery / grid feed-in into the utility grid | Charges the battery with power from the utility grid or feeds energy into the utility grid. | ✓ | ✓ | - |
Intelligent electric vehicle charging | ||||
Fast charging | Charging vehicles with the highest possible charging power. | ✓ | ✓ | ✓ |
Charging with surplus PV energy | Only charging the vehicle with surplus PV energy. | ✓ | ✓ | ✓ |
Intelligent charging | Charging the vehicle to the desired level before departure, taking into account electricity tariffs, PV generation and loads. | - | ✓ | ✓ |
electricity rates | ||||
Fixed-price tariff | Setting fixed electricity tariffs to accurately track costs. | ✓ | ✓ | ✓ |
Time-dependent tariff | Enables basic cost tracking and system optimization based on changing electricity prices. | Manual | ✓ | ✓ |
Dynamic electricity tariffs | Setting and monitoring dynamic electricity prices and optimizing systems based on the dynamic electricity tariff (also includes the StromWallet Dynamic Pro tariff from LichtBlick in Germany). | - | ✓ | ✓ |
Evaluations / analysis | ||||
Consumption, generation, feed-in revenue etc. | Illustrates how much money has been saved or generated through the use of solar energy and dynamic electricity tariffs. | ✓ | ✓ | ✓ |
Load-control | ||||
Reduction of PV feed-in power | Reduction of power generation by the grid operator to ensure grid stability and to reduce grid costs. In this process, battery capacity is reserved in favor of increasing generation output during times of expected curtailment. | - | ✓ | ✓ |
Electricity storage system | Control of the battery system: charging, discharging, setting a specific SOC, SOC calibration, etc. | ✓ | ✓ | ✓ |
EV charger | Control of the EV Charger | Manual | ✓ | - |
| The SMA eCharger is fully integrated into the SMA Energy Maximizer and can control the flow of energy. | ✓ | ✓ | ✓ |
| ✓ | ✓ | - | |
| - | - | ✓ | |
Control via Modbus | Third-party systems can control SMA systems via Modbus at different control levels. | ✓ | - | ✓ |
Heat pumps | Integration of heat pumps (e.g. EEBUS, SG Ready) | SG Ready only | Scheduled | ✓ |
Sockets or relays (e.g. Shelly) | Third-party API integration for integrating sockets and relays (potentially smart home applications as well). | - | Scheduled | ✓ |
End user settings in the SMA Energy App | ||||
electricity rates | End users can set electricity tariffs via the SMA Energy App. | ✓ | ✓ | ✓ |
Energy management targets | The end user can define targets, such as for peak load shaving, the eCharger, sockets and relays | - | ✓ | ✓ |
Technical requirements (in Germany) | ||||
Article 9 Renewable Energy Sources Act (EEG) | The system supports Article 9 with an EEBUS connection. | ✓ | ✓ | ✓ |
Article 14a German Energy Act (EnWG) | The system supports Article 14a via digital inputs or with an EEBUS connection. | ✓ | ✓ | ✓ |
