• Rule 21, Section Hh. (Revision through August 2nd, 2017) for California.
• SRD-UL-1741-SA-V1.1 Updated: 9/26/2017 (Rule 14H) for Hawaii.
2.20.2. Utility – Interactive mode functions
This mode has the functions typically required by UL1741 before supplement A. They are basically voltage and
frequency protections, anti-islanding protection and DC current injection control:
• High/low voltage protection.
• High/low frequency protection.
• Anti-islanding protection.
2.20.3. Grid Support Utility – Interactive mode functions
This mode includes the same functions as the Utility - Interactive mode except the low voltage protection
(incompatible with LVRT).
Additionally, it includes the following functions:
• L/HVRT LOW AND HIGH VOLTAGE RIDE-THROUGH (SA9)
• L/HFRT LOW AND HIGH FREQUENCY RIDE-THROUGH (SA10)
• NORMAL RAMP RATE AND SS – SOFT-START RAMP RATE (SA11)
• SPECIFIED POWER FACTOR (SA12)
• VOLT/VAR MODE (Q(V)) (SA13)
• FREQUENCY-WATT (FW) (SA14 OPTIONAL)
• VOLT-WATT (VW) (SA15 OPTIONAL)
• RATINGS FOR GRID SUPPORT UTILITY INTERACTIVE INVERTERS, CONVERTERS (SA16)

2.20.4. Ratings for grid support functions

In order to maintain a stable grid voltage, the inverters must be able to supply or absorb reactive power from/to
the EPS. One way to achieve this is to make the inverter supply or absorb reactive power in response to the EPS
voltage fluctuations.
The inverter's Volt-VAr mode implements the reactive power response to the EPS voltage fluctuations. This mode
works with the following parameters:
