Off-grid (or “stand-alone”) PV systems are very different than battery-less grid-tied and self-consumption systems. Without the utility as a supplemental electricity source.
When the sun is up, the solar panels generate power to charge the battery bank and provide electricity. At night, the inverter/charger automatically runs your electrical equipment from your battery bank.
You can even have a connection to the grid should you want to use utility power to recharge the battery bank.
