Save More on Your Electricity Bill by Monitoring Your Solar with IAMMETER
Try IAMMETER to See If It Can Help You Save on Your Electricity Bill
If you have a home solar PV system, give IAMMETER a try and see if it can help you reduce your electricity costs.
IAMMETER-Cloud is dedicated to helping solar users optimize their use of solar surplus, increase their solar self-consumption rate, and ultimately minimize their electricity bills.
Even if you've already installed the official monitoring system provided by your inverter manufacturer, you can still use IAMMETER-Cloud. By simply using the cloud-bridge mode to send your data to IAMMETER-Cloud, you can enjoy all the features of the IAMMETER-Cloud Basic version for free.
Explore the system via the Demo Account to discover the full range of features and reports offered by IAMMETER-Cloud.

If You Already Use an Inverter's Official Monitoring System
Send Data to IAMMETER-Cloud via Cloud Bridge
If you're already using the official monitoring platform from your inverter manufacturer, you can use IAMMETER's Virtual Meter to bridge the data to IAMMETER-Cloud in cloud bridge mode — completely free of charge.
This enables access to IAMMETER-Cloud’s powerful Solar PV Monitoring Dashboard, designed specifically for residential solar users. All key metrics from your PV system are displayed in intuitive, clear visualizations:
Note: To access the full functionality shown above, your inverter’s monitoring system must provide data for both solar generation and grid import/export. If only solar generation is monitored, grid-related insights will not be available.
Additionally, new users enjoy one month of free access to the IAMMETER-Cloud Pro version, which includes advanced reporting and analytics features.
Add a Grid-Side Energy Meter
If your current system only monitors solar generation, but you’d like to also track your grid import/export, consider adding an energy meter on the grid side.
We recommend the WEM3050T, a 3-phase Wi-Fi energy meter for just $109 USD. It supports solar net metering and is ideal for home energy monitoring. More info: WEM3050T - one of the Best Choice for Home Energy Management | 3-Phase Wi-Fi Energy Meter
By combining inverter generation data (via cloud-bridge) with grid-side measurements from the WEM3050T, you can unlock IAMMETER-Cloud's full solar dashboard capabilities.
If You Haven’t Installed an Inverter Monitoring System Yet
If you’ve installed a solar inverter at home but haven’t added a monitoring system, we highly recommend considering IAMMETER’s residential solar monitoring solution.
With just one WEM3050T ($109 USD), you can monitor single-phase or split-phase home solar systems. This single meter can track grid usage, solar export, and inverter generation simultaneously.
For three-phase systems requiring both grid and inverter monitoring, two WEM3050Ts are needed.
Setup is simple: Quickly Monitor Your Home Solar System Using WEM3050T
Single-Phase Grid + Single-Phase Inverter
In this setup, the WEM3050T functions as three independent single-phase meters:
- Phase A: Measures bidirectional grid flow (import/export)
- Phase C: Measures solar inverter output
- Phase B: (Optional) Can monitor specific loads of interest
Split Phase Grid + Split Phase Inverter
Split phase (single-phase three-wire) is common in North America, providing both 120V and 240V through a center-tapped transformer.
Three-Phase Grid + Three-Phase PV System
Solar PV Heater Control System
Beyond monitoring, IAMMETER also offers a PV heater control system: Power Your Heater with Solar Surplus and Save on Your Electricity Bill
The WPC3700 is a Wi-Fi power controller designed for pure resistive loads, such as water heaters or space heaters. It can dynamically adjust power output based on available solar surplus.
By pairing the WEM3050T (monitoring grid export) with the WPC3700, the heater operates only when surplus solar is available — maximizing self-consumption and minimizing grid export.

In Conclusion
As the gap between electricity tariffs and solar feed-in tariffs continues to widen, IAMMETER remains committed to helping residential solar users make the most of their systems by maximizing local consumption and reducing grid export.
If you’re not satisfied with your current monitoring solution — or are searching for the right monitoring system — give IAMMETER a try. We believe the savings on your electricity bill will quickly offset the cost of the IAMMETER energy meter.
