6. የአሠራር መመሪያዎች
The B2500-D operates automatically to manage your solar energy. Here's how it works and how to interact with it:
6.1. Energy Flow Management
- During the Day: Solar power generated by your panels flows through the B2500-D to your micro-inverter. This power directly supplies your household appliances, reducing your reliance on the public grid. Any excess energy, when integrated with a smart meter, is stored efficiently in the B2500-D battery instead of being fed back into the grid.
- At Night: The energy stored in the B2500-D is discharged via the micro-inverter to power your household appliances. This ensures a continuous and efficient power supply for devices like routers, refrigerators, and more.
6.2. Smart Meter Integration
For optimal energy management, integrate the B2500-D with a smart meter. This allows for intelligent adaptive output, ensuring that energy is used where and when it's needed most, minimizing waste and maximizing self-consumption.

Image 6.1: Smart Meter Integration. This diagram illustrates how the MARSTEK B2500-D integrates with a smart meter to intelligently adapt power output, distributing solar energy efficiently throughout the home based on demand.
6.3. App Monitoring and Control
The MARSTEK B2500-D can be monitored and controlled remotely via a dedicated smartphone application. This app allows you to:
- View real-time solar power input and output.
- Check battery charge level and status.
