Emergency Stop Signal & PV Rapid Shutdown Signal
Pins 11 and 12 use a normally open & latching switch to connect the two emergency stop pins that cut off the RSD
power supply when triggered, thus stopping the inverter AC output.
Pins 15 and 16 provide the 12V / 100mA signal power lost when the Sol-Ark shuts down using the front button.

The Built-in 12V power supply in the user area of the Sol-Ark (Pins 15 and 16) is rated for
100mA (1.2W)
Transmitter fits inside the user area of the Sol-Ark 8K but can cause interference
(sometimes requires placing it outside of the user area)
TIGO Optimizers are compatible with the Sol-Ark 8K (Do not use the built in 12V Power
supply in the Sol-Ark user area to Power the Tigo Optimizer TX transmitter)
