Access and working space for operation and maintenance of PV equipment such as inverters, disconnecting means and panelboards (not required for PV modules) (CEC 110.26).
Customer Service
Check that the installation manuals for the modules and inverter(s) are at the job site. If the installation exceeds 10 kilowatts, check that the approved plans are available. Review for any changes or errors.
Customer Service
Check that the combiner box is approved for the location in which it is installed and that it meets any temperature restrictions per the nameplate marking or in the installation instructions.
Customer Service
The secret often lies in routine photovoltaic power station combiner box inspection. Acting as the "nerve center" of solar arrays, combiner boxes channel energy from multiple solar strings to inverters.
