Lorawan Energy Meter & Antennas
Lorawan energy meters are also known as:Lorawan electricity meter, lorawan power meter, Lorawan smart energy meter etc. LoRaWAN is a Media Access Control (MAC) layer protocol built on top of LoRa modulation. so we can say we build our Lorawan energy meter based on LoRa technology.
LoRa and LoRaWAN technology principle and advantages and disadvantages
LoRa and LoRaWAN are currently very popular wireless communication technologies in the field of Internet of Things, LoRa is a physical layer technology, LoRaWAN is a communication protocol. They adopt low-power wideband wireless modulation technology, which can provide long distance communication service in long distance, low speed and low power.
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°...
MID & Eichrecht - compliance of EV chargers
Note that so-called 'PTB compliant' chargers actually comply with the German calibration law (Eichrecht). Eichrecht = compliance with MID + “customer protection”: the customer must be able to check charge session data hours/days/months after the actual session...
