PV Meter

The PV and Sub-Meter systems measure the solar inverter's generation energy and collect the utility meter's import/export energy via ECHONET Wi-Sun communication before sending the consolidated data to the server every 30 mins via the LTE mobile networks.

Smart Home Gateway

The Smart Home Gateway equips with LTE, ECHONET Wi-Fi, and Wi-Sun communication for green energy applications. The ethernet port and external antenna options on the smart socket can provide maximum flexibility to the customers (e.g., EV chargers or storage battery applications).

CT Meter

The CT and Sub-Meter systems measure energy generation via dedicated current transformers (i.e., 250A & 500A). Supported by the RS485 network, it can provide energy information for the solar power generation plant with inverter output control features.

OCPP Gateway

The new intelligent OCPP gateway manages 20x EV charging posts and monitors solar inverters to maximize green energy benefits.

It can also cooperate with the MA smart meter for remote power on/off and energy monitor.

DC Meter

The MA DC meter offers various current ranges (e.g., 100A to 500A) to accommodate customer needs. It is equipped with Modbus and LTE (additional communication module) to allow for flexible remote system control and monitoring.

AC DIN Rial Meter

The MA DIN Rail-type meter can measure energy consumption in both directions and remotely control external power relays. This type of meter is suitable for use in EV charging stations. Additionally, it can independently report energy data from the solar system or EV charging post via the Modbus or LTE network.

PV Meter
with Power Relay

The MA BS terminal PV meter can measure energy consumption in both directions and can remotely control internal 100A power relays. It is designed specifically for solar applications and can be set up to create a sub-meter network for a small area. It can be equipped with LTE or Wi-Fi modules to communicate with an internet server for remote control and monitoring.

HD-PLC Communication

The MA HD-PLC communication module provides secure, gigabit-class network connectivity through existing power lines, coaxial cables, or twisted-pair wiring. This solution eliminates costly rewiring and wireless dead zones, providing an ultra-scalable, eco-friendly IoT backbone for modern smart buildings and industrial infrastructure.
