ECC-B System

ECC-B System Description

ECC-B (energy control center)

ECC-B is a crucial component in this ECC-B system, functioning as a communication gateway.
It gathers the operation data of the system and uploads the data to SolaXCloud, establishing a foundation for data monitoring and remote operation.

Microinverter

Currently, we have developed A1-Micro 1 in 1, X1-Micro 2 in 1, and X1-Micro 4 in 1 series. 2 in 1 and 4 in 1 apply to the WiFi version, and 1 in 1 applies to the PLC version.
For 2 in 1 and 4 in 1, the ECC-B only needs to be connected to the meter. For 1 in 1, ECC-B connects to ECC-PLC and matches to the whole system for use.

PV module A

PV Module is an assembly of photovoltaic cells, also known as solar cells. To achieve a required voltage and current, a group of PV modules is wired into a large array called a PV array.
A PV module is the essential component of any PV system that converts sunlight directly into direct current electricity.

Grid

220V / 230V/ 240V grid are supported.

SolaXCloud

SolaXCloud is an intelligent, multifunctional monitoring platform that can be accessed either remotely or through a hard-wired connection. With the SolaX
Cloud, the operators and installers can always view key and up-to-date data and set it remotely.
You can log in to your user account at any time through a personal computer, IOS or Android device to view real-time monitoring data or historical data, and perform remote settings as needed.

Highlights

Load consumption monitoring
Flexible networking with Wi-Fi 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
