The new KarChargers Solar and AC V2G Charger offers a range of advanced features designed to enhance solar energy usage, smart charging, and AC Vehicle-to-Grid (V2G) capabilities. Here's a summary of its key features:
1. Integration with Clip-on/Split Core CTs (Current Transformers)
Single or 3-phase compatibility: These CTs monitor the current flow and enable the charger to use only excess solar energy or manage loads effectively.
Solar Energy Optimization: The charger can be configured to only charge using surplus solar energy, ensuring more efficient use of renewable energy. Comes with Split core CTs with max cable size of 16mm2.
2. App for Usage Monitoring and Solar Parameter Updates
User-friendly app: The app allows users to monitor their energy usage, update charging parameters, and fine-tune solar energy utilization settings.
Configurable settings: For example, users can specify charging to only draw excess solar energy or set a cap on the amount of grid energy used.
3. Modbus TCP Integration
Remote control and automation: Through Modbus TCP registers, users can integrate the charger with platforms like Node-RED and Home Assistant, enabling remote configuration and automation of charging parameters.
Flexibility in management: This feature makes it easier to incorporate the charger into a larger smart home or energy management ecosystem.
4. Integration with ChargeHQ
Cloud-based platform integration: The charger works with ChargeHQ, a platform for managing and optimizing charging, which likely offers additional insights and features for both home and fleet management.
5. V2G (Vehicle-to-Grid) Compatibility
AC V2G hardware included: The charger comes equipped with the necessary hardware for AC V2G, allowing the vehicle to feed energy back into the grid (if the vehicle supports this feature).
OEM Integration: Discussions with car OEMs are ongoing to enable smooth integration with car firmware for V2G functionality.
One-time V2G License: A one-time V2G license may be required to unlock V2G functionality, subject to vehicle and grid compatibility.
Bi-directional inverter requirement: To enable V2G AC functionality, the vehicle must also be equipped with a bi-directional inverter (enabling both charging and discharging of the battery).
This charger offers significant flexibility, making it ideal for those looking to optimize their use of solar energy, integrate their EVs into a smarter grid, and leverage automation for more efficient energy management. The V2G capability, in particular, aligns well with future-proofing energy systems and helping contribute to grid stability.
