5. പ്രവർത്തന നിർദ്ദേശങ്ങൾ
The VENUS E 3.0 operates largely autonomously, especially with AI optimization. Here's how to manage its operation:
5.1 Power Management Modes
The device offers several operating modes, configurable via the mobile application:
- Self-Optimization: Stores surplus solar energy and automatically discharges when solar production is insufficient, reducing grid usage.
- AI ഒപ്റ്റിമൈസേഷൻ: Analyzes market electricity prices and real-time electricity generation forecasts to create optimal charging and discharging schedules, minimizing energy costs.
- Self-Consumption (Eigenverbrauch): With the integrated Smart Meter, the Venus E 3.0 monitors household power consumption to maximize self-consumption and optimize overall energy utilization.
- മാനുവൽ: Allows users to customize individual charging and discharging times and power settings.
