The SMeter-RS07 is a new generation of rail-mounted CT AC electricity meter specifically developed for photovoltaic storage equipment (single-phase two-wire, three-phase three-wire and three-phase four-wire, split-phase). It supports up to 6 CT connections in dual channels. The device is equipped with extended WiFi and LoRa wireless networks, RS485 data communication, PLC communication, phase sequence misalignment and CT current reverse calibration functions. By connecting to the cloud IoT platform through a router and cellular network, it enables remote data monitoring, remote control, remote upgrade, remote maintenance, edge-side energy interconnection, local debugging, etc. of the equipment. It supports wireless or wired networking of multiple photovoltaic storage devices for parallel operation and anti-reverse current control. It is an important control center for household energy management and monitoring systems. It can achieve the fastest data response speed of 500ms for wireless and 50ms for wired connections. Application scenarios: household energy data monitoring, anti-reverse current application for photovoltaic storage equipment, AC coupling multi-channel monitoring, etc.
Easy to use
(1) Installation is simple: rail-mounted installation;
(2) Configuration is simple: local setup (APP), remote setup;
(3) Maintenance is simple: remote maintenance, remote firmware OTA upgrade;
(4) Usage is simple: power on, connect to network, register and bind;
General
(1) Component selection: High-performance components, capable of operating for a long time at -20°C to +65°C;
(2) Communication stability: Real-time command monitoring, network disconnection detection, long-term operation detection;
(3) Data security: TLS-TCP connection, private protocol, data verification, data retransmission (data is saved when the network disconnects and retransmitted when the network reestablishes).
Flexible
(1) Protocol Compatibility: Supports multiple communication protocols for communication;
(2) Local and Remote: When used with the APP, it can simultaneously perform local monitoring and achieve remote control;
(3) On-site Parameter Configuration: When used with the APP, it can read and set parameters on-site;
