Frequently Asked Questions
•What are the optimal battery settings for peak shaving with the EG4 18KPV?
Optimal battery settings depend on the battery chemistry and application. Consult the battery manufacturer's specifications for recommended voltage and current limits. Configure the inverter to prioritize battery discharge during peak demand and recharge during off-peak hours. Consider setting a minimum SOC to prevent excessive battery depletion.
•How do I integrate the EG4 18KPV with a building management system (BMS) for advanced peak shaving control?
The EG4 18KPV supports Modbus TCP/IP communication, allowing integration with a BMS. Use the BMS to monitor inverter parameters, such as power output, battery SOC, and grid import/export. Implement control algorithms within the BMS to dynamically adjust peak shaving settings based on real-time load conditions and grid pricing signals. Ensure proper network security and authentication.
•What are the NEC requirements for rapid shutdown (RSD) with the EG4 18KPV in a commercial building?
NEC 2017/2020 requires rapid shutdown of PV systems in commercial buildings. The EG4 18KPV should be equipped with a compliant RSD system that can de-energize the PV array conductors within a specified time frame. Locate the RSD initiation device in an accessible location, typically near the main service disconnect. Label the RSD system clearly.
