You will see same UI with IAMMETER web portal if you access to the demo link by computer. You will see same UI with IAMMETER app if you access to the demo link by mobile phone. We recommend you to access via computer so you can see more functions and reports.

1. Introduction

IAMMETER-solar

Our solar PV monitoring solution includes,

  1. Bi-directional Wi-Fi power meter: single phase energy meter(WEM3080) and 3 phase energy meter(WEM3080T).

  2. Solar PV monitoring system: IAMMETER-cloud or IAMMETER-docker

Bi-directional Wi-Fi energy meter

WEM3080(single-phase energy meter) and WEM3080T(The three-phase energy meter also supports split-phase usage which means it can be used as three single-phase energy meters.) can be used to monitor your solar PV system. Both single-phase energy meter and three-phase meter are bi-directional. If the energy meter is installed on the grid side, both export and import energy parameters (consume power, feed-in power, energy consumed from the grid, energy exported to the grid) can be measured simultaneously.

If your grid system and inverter are both single-phase, you can use one three-phase energy meter (recommend) or two single-phase energy meters to monitor your solar PV system. Compared to using two single-phase energy meters, using one three-phase energy meter to monitor the solar PV system has such advantages.

  1. Support net energy metering: this 3 phase energy meter supports both normal metering mode and net energy metering mode.
  2. All three-phase power measurement is sampled at the same time. So there is no synchronized problem when calculate the load power by the inverter power and grid power.

Solar PV monitoring system from IAMMETER-Cloud

IAMMETER is our online energy monitoring system, that can monitor your solar PV system by its web portal and mobile APP. Key features related to IAMMETER solar PV monitoring system are,

  1. Monitor the realtime data: inverter power output, feed-in power(to grid),import energy (from grid), export energy(to grid) etc.
  2. Calculate the parameters: solar PV efficiency, self-consumption ratio, etc.
  3. various report that help you analyze your analyze your solar pv system:help you analyze your solar pv system and improve its performance.

2. Install Wi-Fi energy meter in your solar PV system

2.1 Monitor only "From Grid" and "To Grid" energy in single phase system

You have a single-phase solar and grid system, and your intention is to measure the grid consumption as well as the energy exported to the grid . QuickStart for monitoring your solar PV system by WEM3080

By installing only one WEM3080 in your single phase solar PV system, you can monitor two-way power and energy , the energy consumed from grid and exported to grid simultaneously.

2.2 Monitor both the single-phase solar and grid systems simultaneously

You have a single-phase solar and grid ,and you want to monitor both of the grid and the solar in your system.

Quick Start for monitoring your solar PV system by WEM3080T

By installing only one WEM3080T in your single phase solar PV system, and clamping the first CT onto grid, the second CT onto solar inverter side and the third CT onto load if applicable (you can also leave the third CT unclamped if not needed), you can monitor "From Grid" (the energy consumed from the grid), "To Grid" (the energy imported to the grid) and the energy produced by solar inverter. You will also see the direct self-use energy and the energy consumed by your load.

2.3 Monitor both grid and solar in split phase system

A split-phase or single-phase three-wire system is a prevalent type of single-phase electric power distribution in North America, commonly used in residential and light commercial applications. It involves supplying two 120 V AC lines to premises that are 180 degrees out of phase with each other concerning the neutral, along with a common neutral.

Because the two-phase output is balanced, measuring the inverter output can be accomplished using a single phase. This is achieved by configuring the meter to multiply the reading obtained from that single phase by two.
