Time of Use
Time of use is designed to help homeowners save money by optimizing energy use based on electricity rates that vary throughout the day.
![]() | This mode gives homeowners greater control over the system; however, it requires a carefully planned schedule to ensure optimal performance. If not set up correctly, the system may not function as expected. |
![]() | In some areas, Utility companies may limit customization options for the TOU operating mode. |
How it works:
- Peak Hours (Expensive Electricity)
- The system discharges stored battery power to power your home, avoiding costly grid electricity.
- If solar is available, it is used first before tapping into battery storage.
- Off-Peak Hours (Cheaper Electricity)
- The system charges the batteries using either solar energy or lower-cost grid electricity.
- If needed, home appliances can run on grid power since rates are lower.
- Solar Integration
- During the day, solar energy is used to power the home and charge the batteries.
- Any excess energy is stored for later use instead of being exported to the grid (unless net metering is beneficial).
Benefits of TOU Mode:
- ️ Reduces Electricity Costs – Avoids using expensive electricity during peak hours.
- ️ Maximizes Battery Value – Uses stored energy strategically to optimize savings.
- ️ Solar – Ensures solar energy is used efficiently for self-consumption and peak-time savings.
Example of TOU Optimization:
Peak (4 PM – 9 PM) → Use battery power instead of expensive grid energy.
Off-Peak (9 PM – 6 AM) → Charge batteries from the grid (if solar isn’t available).
Midday (10 AM – 3 PM) → Use solar power for home + charge batteries.

What does Off-peak and On-peak mean?
These terms are used to identify the price of electricity based on your tariff, see the definitions below:
- Super Off-Peak – The lowest electricity rates of the day.
- Off-Peak – Energy prices are low but not at their lowest.
- Mid-Peak – Electricity rates are moderate.
- On-Peak – The highest electricity prices of the day.
