Function Introduction of ECC
The gateway ECC is a energy control center which collects PV production data and energy consumption data and delivers it to the SolaX Cloud via flexible networking with WI-FI,4G and Ethernet.ECC enables users to conveniently manage remote operation and maintenance of their PV system anytime and from anywhere by SolaX Cloud or SolaX App.
Function Introduction of ECC-PLC
SolaX gateway ECC-PLC is used to collect PV production data and energy consumption data and delivers it to the ECC via RS485. Besides, it support bidirectional communications for remote maintenance. With integrated optional production metering and consumption monitoring, the ECC-PLC is the platform for smart energy management.
Highlights and key Features of ECC
• Load consumption monitoring
• Flexible networking with Wi-Fi, 4G and Ethernet
• 5V USB port available
• Internal relay available to control external devices
• Support seamless communication with peripherals through RS485 and Ethernet
• Support remote operation and maintenance
Key Features of ECC
1. Monitoring and Management
- The system capacity:40 microinverters with built-in PLC.
- Support local/remote setting and monitoring.
- Support batch upgrade.
2. Export Control
- Limit power that exported to the electricity grid by adjusting the production power of the inverters.
- The system requires ECC,ECC/PLC,A1-Micro 1 in 1*.
- Fast responds to avoid the unexpected feed-in especially when the loads drop rapidly.

3. Ripple Control(being developed)
- The Ripple Control Receiver is required to implement the ripple control function.
- Ripple Control Receiver is a receiving device that can analyze the high-frequency signal sent from grid operator and trigger different status of switches accordingly.
- Each status can be set and assigned to a power control action.
- In total 16 status and actions can be programmable.
4. Local Data Storage
- Support up to 64GB TF card to store the data of 40 A1-Micro 1 in 1 units for 90 days
- Ideal for the offline site management
5. Microinverter Consumption Mornitoring(without PLC)
Figure 3 Microinverter Consumption Mornitoring(without PLC)
- Currently compatible inverters :X1-Micro 2 in 1,X1-Micro 4 in 1
- Support export ripple control/DRM
- The ECC and Microinverter will automatically check the time with web after powering on.and the data of meter and microinverters will be independently to the solax cloud every 5 minutes in integer time.
6. Microinverter Consumption Mornitoring(with PLC)
Figure 4 Microinverter Consumption Mornitoring(with PLC)
- Currently compatible inverters:A1-Micro
- Support export control/ripple control/DRM
- By connecting Production CT and Consumption CT on the grid-connected side and PV side,ECC-PLC can transmit the collected microinverter power generation and grid-connected power data together with the microinverter data to ECC and then to the solax cloud.
Highlights of ECC-PLC
- Real-time load and PV production monitoring
- Web-based monitoring and control
- Bidirectional communication for remote upgrades
- Built-in industrial-grade PLC module
- Support for remote operation and maintenance
