FAQ

ADL400W Wireless Dual-channel Three-phase Energy Meter

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 or Lora 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.
