Monitoring Solutions for Combiner Box designs in
PV Combiner Boxes can offer DC OFF switches and/or fuses that disconnect the array from the PV inverter. These help to manage the safety conditions of the array during periods of maintenance (like cleaning, inspection or repair).

5 FAQs about [Photovoltaic combiner box on-site inspection process]
What are the mounting and grounding procedures for a PV module?
The PV module mounting and grounding procedures used should follow the instructions provided in the installation manuals for the racking system and the PV module. The mounting structure or racking system wind loading and snow loading requirements are met, and the array setbacks from the roof edge meet fire codes.
What are the requirements for a roof-mounted PV system?
Firefighter access according to approved plan. Roof-mounted PV systems have the required fire classification (CBC 1505.9 or CRC R902.4). Grounding/bonding of rack and modules according to the manufacturer’s installation instructions that are approved and listed.
What is a DC combiner box?
Conduit runs between sub arrays and to DC combiner boxes are installed in a manner that minimizes total amount of conduit on the roof by taking the shortest path from the array to the DC combiner box. (CFC 605.11.2 & CRC R331.3) DC Combiner Boxes are located so that conduit runs are minimized in the pathways between arrays.
Where should a photovoltaic circuit be located?
(CBC 1509.7.2 & CRC R908.1.2) Conduit, wiring systems and raceways for photovoltaic circuits are located as close as possible to the ridge, hip or valley and from the hip or valley as directly as possible to an outside wall to reduce trip hazards and maximize ventilation opportunities.
Where is a photovoltaic power source marking located?
Marking is placed adjacent to the main service disconnect in a location clearly visible from where the disconnect is operated. (CFC 605.11.1.3 & CRC R331.2.3) 67. The markings say “WARNING: PHOTOVOLTAIC POWER SOURCE” and have 3/8-inch (9.5 mm) minimum-sized white letters on a red background.
