Acrel ADL400W Three Phase CT Operated Din Rail Energy Meter WiFi-Halow Communication

General

ADL200W ADL400W Series DIN-Rail Mounted Multifunctional and Dual Circuits Electric Energy Meter With External Current Transformer is an intelligent instrument mainly designed for new energy power generation systems such as photovoltaic grid-connected system, micro inverter system, energy storage system, AC coupling system, etc. The product has the advantages of high precision, small volume, high respondent speed and convenient installation. It can monitor and measure real-time power and other power parameters, support protocols such as Modbus-TCP and http, and communicate with inverters or energy management systems (EMS) via Wi-Fi HaLow communication to achieve functions such as anti-reverse flow, regulating power generation, and battery charging and discharging. It can be bidirectionally measured to achieve energy management for household distributed photovoltaic systems.
