In an off-grid PV system, the power coming from AC and DC that will be used to supply 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). The distribution panel for an off-grid PV system 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. 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 ratings
- Equipment certifications
