In an off-grid PV system, the output of a power soure - AC or DC - that will be used to supply multiple loads will typically pass through a distribution panel that will have overcurrent protection devices that will allow small diameter wires to be run to outlets, lighting and other loads. There will also typically be busbars for equipment grounding conductors and grounded conductors (AC neutral). A distribution panel may be a traditional distribution panel like is commonly seen in grid-connected electrical systems (as depicted in the graphic) or it may be a specifically designed for use in off-grid PV applications. They may differ in appearance, but the purpose and function is the same. A distribution panel must be suitable for the conditions in which it will be used including:
- Maximum ampacity
- Maximum voltage
- Phases (L1, L2, L3 etc.)
- Sufficient space for necessary overcurrent protection devices.
- Weather rating
- Equipment certification
