Usage

For residential users: Monitor all home electrical circuits (e.g., heating, kitchen, EV charging), understand which devices consume the most energy, integrate with solar systems and track real energy balance
For engineers / energy specialists: Perform energy audits, analyze load distribution between phases, optimize energy consumption and reduce costs
For electricians: Install modern solutions for clients, quickly identify panel issues, replace multiple meters with a single device
For solar systems: Monitor generated and consumed energy, analyze grid export, increase system efficiency

Practical application

For homes – monitor how much electricity each circuit consumes (heating, sockets, EV) and reduce costs.
For business – analyze electricity consumption across different zones or equipment and optimize expenses.
For electrical panels – one device replaces multiple meters and provides a full system overview.
For solar systems – see how much energy you consume and export to the grid.
For diagnostics – quickly identify which circuit causes the highest load or issue.
