FAQ
The difference between M-Bus and Modbus
At first glance, M-Bus and Modbus are very similar, no matter on alphabet or pronunciation. The more similar things are usually easier to get confused. At the same time, these two terms are related to the electricity meter industry, so let's learn the difference between M-Bus and Modbus today.
Undirectional and Bi-directional Meter in Solar System
Previously, IVY have introduced bi-directional meters. Therefore, some customers contact us to know if we have other types of energy meters for solar energy system. The answer is YES. Based on different working way of solar panels, IVY can provide corresponding metering solutions. Let's take a look!

What are the differences between RS232, RS485, RS422 and RJ45 interfaces
RS-232, RS-422 and RS-485 are serial data interface standards.
What is Four Quadrant Metrology?
P—active energy; Q—reactive energy; QL—inductive reactive energy; QC—capacitive reactive energy; S—apparent power Forward active power: P=UICOSΦ, where the range of Φ is within ±90°. Reverse active power: P=UICOSΦ, where Φ ranges from 90° to 270° Forward reactive power: P= UISINΦ, where the range of Φ is within 0~180°...
What is the difference between M-Bus and MODBUS communication ?
M-Bus Communication: M-Bus is a communication protocol used between meters and the central data collection system or Pre-Payment unit. Widely used on new projects where the building infrastructure can be designed accordingly.M-Bus is available on a wide variety of gas, heat, electricity, and cold/hot water meters.
