Want to Cut Your Electricity Bill? Try IAMMETER’s Solar Energy Monitoring Solutions
IAMMETER, a professional energy management and solar monitoring solution provider, has been dedicated for nearly a decade to helping residential users reduce electricity bills and maximize their solar investment.
This article outlines several ways IAMMETER can help you save on electricity costs.
Some methods are free, while others require affordable investments in smart devices such as IAMMETER energy meters and Wi-Fi power controllers.
Choose the method that best fits your needs and budget.
Compare Electricity Tariffs with IAMMETER’s EFSS Tool
Cost: Free
Requirement: Hourly energy consumption data
Choosing the best electricity plan can be confusing with so many electricity retailers offering different tariff structures. IAMMETER’s Energy Forecasting and Simulation System (EFSS) helps you compare electricity tariffs and find the most cost-effective option.
- For IAMMETER users: Import your IAMMETER data directly into EFSS and test different electricity tariff plans. The platform will calculate your electricity cost under each plan.
- For non-IAMMETER users: Upload your hourly kWh data as a CSV file to EFSS and compare different tariff templates.

Monitor Solar PV and Grid Power with WEM3050T
Cost: USD 109 (price for one WEM3050T)
For single-phase and split-phase systems, one WEM3050T can simultaneously monitor inverter solar generation and grid import/export.
For three-phase systems, you’ll need two WEM3050T units to track both the grid and inverter output.
Why it saves money:
By using IAMMETER’s solar energy monitoring system, you can track both your solar yield and grid usage via IAMMETER-Cloud (web & app). This lets you identify the best time to run high-consumption appliances—maximizing solar self-consumption and minimizing grid purchases.

Control Electric Water Heater Power with Solar Surplus (WEM3050T + WPC3700)
Cost: USD 109 (WEM3050T) + USD 199 (WPC3700)
This solution adds smart load control to your monitoring setup. The WPC3700 Wi-Fi Power Controller dynamically adjusts your electric water heater power input based on available solar surplus power.
That means you can heat water entirely with solar surplus, reducing or eliminating exported energy.
More details: Powering the electric water heater with surplus solar generation
Results:
- Before: High exported energy to the grid.
- After: Exported energy close to zero, with surplus power consumed locally.
Before:
After:
Best for users who:
- Have a solar system with high feed-in proportion but low feed-in tariff.
- Own large resistive loads such as electric water heaters (not heat pumps).
- Require loads rated under 250V and 25A.

Smart EV Charging with Solar Surplus via OCPP
Cost: USD 109 (1 × WEM3050T)
IAMMETER-Cloud supports OCPP-based EV charger control, enabling you to charge your EV only with surplus solar power.
When surplus power exceeds your configured threshold, the system automatically starts EV charging.
