Live Solar Status
This blog is powered by a balcony solar system in Athens, Greece — a mix of bifacial panels (~500W) and a couple of non-bifacial ones (~400W), split across two EcoFlow Stream Ultra inverters (4 MPPT inputs each), with a 1.92 kWh battery in each unit 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
Where the energy comes from: PV Production, Inverter Output, PV to Battery, and Grid Import.
