Here’s a Typical Day of Savings

6 AM – 9 AM: Starting with Solar

From the first light of the day, the system begins capturing early solar energy to power your morning routine. During peak-price hours, solar and stored energy keep your home running efficiently.

9 AM – 6 PM: TOU Savings

HEMS intelligently balances solar, battery, and grid usage based on your habits and dynamic electricity prices. Energy automatically shifts to the most cost-efficient source at every moment.

6 PM – Midnight: Solar at Work

Stored solar energy powers your home through the evening peak. HEMS ensures sufficient battery reserve to comfortably cover night-time demand.

Midnight – 6 AM: Charge for Tomorrow

During low-tariff hours, the system recharges using off-peak grid electricity. Your battery is topped up and ready for the next day’s morning peak.
