Live Solar Status
This blog is powered by a balcony solar system in Athens, Greece — 4 x 520W bifacial panels (~2 kWp) feeding an inverter with 4 MPPT inputs and 1.92 kWh battery, paired with a 1.92 kWh expansion battery for a combined 3.84 kWh storage. A Shelly Pro 3EM monitors grid consumption. Data is collected via Prometheus, and these charts update every 5 minutes.
PV String Production
Individual solar panel string output (stacked). Each string connects to a separate MPPT input.
Battery State of Charge
How the batteries charged and discharged today. Combined is the overall system capacity.
Power Flow
