On a residential PV system - with an ESS - how is the following Code-required label properly worded:
2017 NEC 706.7 (D)
Notification. The disconnecting means shall be legibly marked in the field. The marking shall meet the requirements of 110.21(B) and shall include the following:
(1) Nominal ESS voltage
(2) Maximum available short-circuit current derived from the ESS
(3) The associated clearing time or arc duration based on the available short-circuit current from the ESS and associated overcurrent protective devices if applicable
(4) Date the calculation was performed
I got (1). 450/400 VDC charge/discharge.
I have no idea about 2 and 3.
Is this even applicable?
Equipment is SolarEdge Storedge 7600A-US with LG CHEM RESU10HR
