The role of pulling out the photovoltaic inverter terminals

The ability of a PV inverter to detect and interrupt series arcs (AFCI, or Arc Fault Circuit Interrupter) is a useful safety feature. In the US the National Electrical Code (NFPA 70) requires PV systems to be capable of detecting high voltage DC arcs, whether through functi onality built into the inverter or by other means. However, the testing

Using disconnects with pull-out fuses is one method to disconnect a fuse from all sources of energy. Disconnects for fuses must be installed for PV output circuits where fuses that must be serviced can’t be isolated from energized circuits.

PV inverter PV modules Figure 1. A simplified PV-system layout. For example, the amount of light available naturally contrib-utes to the PV-cells' current output, whereas the voltage out-put is inversely affected by the cell temperature. Between the PV-panels and the AC grid are the balance-of-system (BOS) components.

PV inverters responding to internal anti-islanding software may have energized outputs up to two seconds after the ac utility power is removed from the inverter output. These PV inverter-energized load-side terminals on the main circuit breaker may cause the GFP trip mechanism to be destroyed if that trip mechanism is connected to and receives .

Open the inverters and any combiner boxes to check for proper torque on all DC terminals. A common test here is to tug each wire to see if any are loose or pull out entirely. If any wires are suspect, tighten them down to proper torque specs.
