How it works


1. MORNING
Solar panels convert sunlight into electricity. With the POWERSTATION 247 this energy can be directly used and optimized to ones own usage. When the inverter is working in mains-interactive mode, the inverters’ energy injection into the residential power grid is real-time controlled.
It compensates the appliance demand (own consumption) immediately. If the PV harvest is higher than the power demand, the overgenerated energy is stored in the battery. If the appliance demand, due to load peaks, is higher than the PV output, the inverter takes the necessary additional amount of energy from the battery.
At forenoon, the PV generation is usually higher than the own consumption.
During this time interval, just the same during early afternoon, the batteries will be 100% charged.



How it works in the afternoon

2. AFTERNOON
When the battery is fully charged, the system covers the own electricity consumption from the solar panels. Only if the solar harvest is higher than the own demand at full batteries, the overgenerated energy is fed into the public grid.
At any time, the system cuts all appliance power peaks using the stored battery energy.



How it works at late afternoon and night

3. LATE AFTERNOON / EVENING
During late afternoon the solar harvest decreases, while the energy need in your household increases. The battery replaces exactly that amount of energy that is not delivered from the PV modules.
In the evening, when there is no solar irradiation anymore, the inverter, still in utility-interactive mode, takes the input current solely from the battery until the battery is discharged. Then, the remaining electrical energy is taken from the public grid.
The battery remains an emergency capacity of 15-20% to cover the night if a grid failure occurs.



How it works while outage

4. POWER OUTAGE
If the public utility fails, the integrated load transfer switch disconnects the utility from the residential grid. The inverter changes to stand-alone mode and powers the connected home appliances until the battery is empty. Every solar harvest is added to the inverter and the battery reserve to extend emergency power and duration.
When the utility returns and is stabilized, the system automatically switches back to utility-interactive mode.
