Greetings all we frequently install SMA 'Sunny Boy' inverters.
I have always considered inverters to fall under 110.26 rules for working clearance, and it usually is not a problem to meet 110.26.
Currently we have a project where a inverter is going to be installed in a laundry room in a multi family complex and the 'best' place to put the inverter is on the wall behind a cloths washer.
Now that PV systems have a Rapid Shutdown/DC disconnect initiator and I am wondering if 110.26 applies to inverters any more? (or ever did) as you would could safely de-energize the inverter from both AC and DC before servicing it.
I guess my question is two part
A) does a 'DC disconnect initiator' qualify as a 690 Part III. Disconnecting Means:
690.13 "Photovoltaic System Disconnecting Means. Means
shall be provided to disconnect the PV system from all wiring
systems including power systems, energy storage systems, and
utilization equipment and its associated premises wiring.
(A) Location. The PV system disconnecting means shall be
installed at a readily accessible location."
and
B Are there any other provisions in 690 that require working space around an inverter?
Thanks in advance.
