About EFSS

EFSS (Energy Forecasting and Simulation System) is the latest online tool from IAMMETER.

It can be used by anyone, regardless of whether they are IAMMETER-cloud users.

EFSS currently offers two main functionalities:

1. It calculates the actual electricity bill based on the customer's real electricity consumption and feedback, helping to identify the most cost-effective electricity tariff.
2. It analyzes the benefits and return on investment (ROI) of introducing an energy storage system based on the customer's actual electricity usage data.

Please note that you can use EFSS regardless of whether you are an IAMMETER user. The only difference is that IAMMETER users can directly import the hourly kWh data (from grid, to grid, yield) required by EFSS. Non-IAMMETER users need to prepare this data themselves and upload it to EFSS according to the CSV file format.

For instructions on how to use EFSS, please refer to the EFSS User Manual.

For any questions about using EFSS, you can communicate directly with us through our official forum.
