The ADL series single-phase rail type photovoltaic energy meter is an intelligent instrument designed mainly for new energy generation systems such as photovoltaic grid connected systems, micro reverse systems, energy storage systems, and AC coupling systems. The product has the advantages of high accuracy, small size, fast response speed (100ms), and easy installation. It has the ability to sample, measure, and monitor power parameters, communicate with inverters or energy management systems (EMS), and achieve functions such as preventing backflow, adjusting power generation, and battery charging and discharging based on real-time power and accumulated energy. It can measure in both directions and achieve distributed photovoltaic energy management for household use.

Application scope:Suitable for single-phase and three-phase AC systems with a rated frequency of 50Hz.

Measurement function:Capable of measuring all electrical parameters including voltage U, current I, active power P, reactive power Q, apparent power S, power factor PF, and frequency. Voltage U is rounded to 1 decimal place, frequency F is rounded to 2 decimal places, current I is rounded to 2 decimal places, and power P is rounded to 3 decimal places. For example: U=220.1V, f=49.98Hz, I=1.99A, P=0.439kW

The instrument also provides high-speed response registers for the above electrical parameters

Measurement function:Can measure the current combination of active energy, forward active energy, reverse active energy, forward reactive energy, and reverse reactive energy.
