The system is shown actively managing energy for the household, with a family visible in the foreground, suggesting a comfortable and energy-efficient lifestyle. Another scene depicts the interior of a home at night, with the energy storage unit providing power, highlighting its role as a reliable backup source.
APP & Cloud Integration
Only a single Wi-Fi router is needed to enjoy Delta's comprehensive cloud service, enabling smart monitoring and control of your energy system.
Screenshots illustrating the DeltaSolar mobile application interface:
- Real-Time Data: Displays current energy metrics such as "TODAY ENERGY" (e.g., 4.5 kWh), "Total" (e.g., 15.6 kWh), and "Today Power" (e.g., Production 0.00 W, Consumption 0.22 W, Purchased 0.22 W).
- Data Curve: Presents historical energy data over time, showing trends for production, feed-in, consumption, purchased power, charge, discharge, and battery SOC (State of Charge). Example data points include "Energy: 12.320 kWh" and "Battery SOC: 38.8 kWh".
- Function Setting: Provides options for system configuration, including "Connection", "Grid Setting", "Network", and "Maintenance".
The MyDeltaSolar Cloud platform offers a web-based interface for detailed monitoring and management of the energy system, providing a comprehensive overview of plant data, energy flow, and operational status.
The DeltaSolar app is available for download on Google Play and the App Store.
System Architecture
The Delta energy storage system offers flexible configurations to meet various energy needs, including hybrid energy storage and backup power solutions.
Hybrid Energy Storage System
A diagram illustrating the components and connections of a Hybrid Energy Storage System. Key components include: Solar Panel, BX6.3_EX and BX6.3_DD battery units, H5E/H8E/H10E and M6E/M8E/M10E inverters. These are connected to the Main Load (represented by icons for Washing Machine, Air Conditioner, Cooking appliance, and Microwave) and the Grid via a Current Transformer (CT). DC Power is shown flowing from the Solar Panel to the inverters, and AC Power flows between inverters, loads, and the grid. Dashed lines indicate potential Power Cuts.
Hybrid Energy Storage System with Backup Power
Normal Condition
A diagram showing the system in normal operation with backup power capability. Similar to the Hybrid Energy Storage System, but with the addition of an ATS Box (Automatic Transfer Switch) between the inverters and the Main Load/Grid. The Critical Load (represented by icons for Charging, Surveillance Camera, Light, and Computer) is also shown, indicating specific appliances that would be prioritized during an outage. Power flows normally from solar/grid to main and critical loads.
Emergent Condition
A diagram depicting the system's operation during an emergent condition, such as a power cut. In this scenario, the ATS Box isolates the system from the grid. Power from the Solar Panel and battery units (BX6.3_EX, BX6.3_DD) flows through the inverters (H5E/H8E/H10E, M6E/M8E/M10E) to supply only the Critical Load (Charging, Surveillance Camera, Light, Computer), ensuring essential appliances remain operational. The Main Load is disconnected from the system during this condition.
