Keep the breaker on
After CFE interconnection, the load-center breaker next to the inverter must stay on so the system can transmit solar energy.

Basic guide
After installation
We turned the key points from the photovoltaic manual into simple client-facing steps.
Check the inverter and monitoring app
The inverter shows the energy being produced at that moment. The app lets you review current and period-based generation.
Understand your bidirectional meter
During the day you use solar energy and surplus energy is sent to CFE as credit. At night, CFE supplies the energy you need.
Calculate your bimonthly balance
The difference between your credit and consumption indicates the kWh to be covered with CFE.
Protect the internet signal
If the modem is far from the inverter, a WiFi repeater may be needed to keep monitoring stable.
Keep your estimated production handy
Your advisor should share how many kWh your system will produce; this helps compare expectations against results.
