Solar integration with electric vehicle (EV) charging stations is an innovative and sustainable approach that combines solar power generation with the charging infrastructure for electric vehicles. Couple examples why this integration is important:
- Solar-integrated TeltoCharge can be connected to the local electrical grid, allowing it to draw power from the grid when solar energy production is insufficient or when there is a high demand for charging. This ensures uninterrupted charging availability for EV owners.
- Solar Power Offset: When solar panels produce excess electricity that is not immediately consumed by TeltoCharge, it can be fed back into the electrical grid. This process, known as net metering or feed-in tariff, allows the solar system owner to earn credits or receive compensation for the surplus energy supplied.
- To ensure proper solar integration functionality, it is essential to begin with the correct physical installation. This involves having a smart energy meter installed in the electric circuit that possesses the necessary communication functionality and is included in the energy meter whitelist. The meter plays a crucial role in detecting negative current flow, indicating when energy consumption is lower than solar generation, and feeding it back into the electrical grid. For effective communication, the charger must be interconnected with the meter.
- When the meter detects surplus energy, it relays this information to the charger. Based on the charger's internal configurations, it will determine whether to initiate the charging process or not. It is important to note that this process depends on the specific configurations set within the charger.
- More information about smart meter set-up can be found here
- Energy meter type: You need to select the type of smart meter (1-phase/3-phase). Please note that you can use a 1-phase charger even if the meter is 3-phase.
- RS-485 baud rate: This information can be found in the meter settings accessible through the meter display. If the client cannot locate it, it is recommended to refer to the smart meter manual.
- RS-485 parity/stop bit: Similarly, this information can also be found in the meter settings. If the client is unable to find it, it is advisable to check the smart meter manual.
- Measuring device: The meter should be selected. For UK chargers, it is possible to choose CT clamps.
- Energy meter address: This information can be found in the meter settings accessed through the meter display. If the address cannot be located, it is recommended to consult the smart meter manual.
- Current update interval: By default, it is set to 3 seconds. However, there may be cases where the user needs to increase this value. For instance, if there are significant distances between the chargers and the smart meter or if there are numerous interconnected chargers.
