FAQ
Q: Which communication protocols are supported for third-party smart meters and monitoring integrations?
A: The system utilizes an integrated 2.4 GHz Wi-Fi module to connect to our VIP Cloud network. For local hardware orchestration, it interfaces seamlessly with standard external smart meters and features local edge computing capabilities.
Q: What is the continuous and peak output power capacity when operating in off-grid/backup mode?
A: The system delivers a maximum continuous off-grid output power of 2500W at a stable 230V / 50Hz. For inductive loads with high starting currents (such as water pumps or air compressors), the system provides a robust peak output power of 3000W.
Q: Does this product comply with local utility interconnection standards for the European market?
A: Yes, the system is fully certified under VDE-AR-N 4105 (Germany), EN50549-1, and EN50549-10:2022 (Europe).
Q: How does the system protect itself during sub-zero winter temperatures?
A: The integrated BMS actively monitors cell thermistors and will safely restrict charging if temperatures drop below freezing to prevent lithium plating, ensuring absolute cell protection until temperatures return to optimal operating thresholds.
Q: How is the physical installation handled? Does it require specialized heavy tooling or wiring?
A: The system is explicitly designed around a modular, tool-free plug-and-play ground installation concept. This eliminates internal DC terminal wiring, severely cutting down on-site labor hours for installation crews.
