RESIDENTIAL Example System
400 to 1000 Watt Grid-tied PV Array with battery backup, 24 Volts Nominal Primarily AC Loads and Select DC Loads
This drawing illustrates how a PV (photo voltaic) system breaks down into three major Subsystems:
- Array at the top
- Power Conditioning at image center, and
- Battery Bank below
- Example system power production - 1800 watt hours daily from a 5 hour equivalent day.
- Batteries - L-16 type, 6 volt, 300-370 amp hours.
- Inverter - 1,500 to 3,600 watt modified sine with built-in battery charger and transfer switch.
- Power conditioning and storage placement - dwelling basement or utility area, powershed or container.
We can easily take any of these subsystems and alter the others. For example, the array or battery systems could vary greatly in size. In a grid intertie system you typically wouldn't even need batteries! Also, one could easily picture wind turbines and/or micro-hydro sub-systems in place of or even side by side with the PV sub-system.
If some of these terms seem unfamiliar, don't worry, we'll start to cover them in the next section!
