Integrating Sensors and Accessory Placement
Battery Temperature Sensor
• Place between batteries with tape (See Fig. C).
• This sensor has no polarity and helps perform voltage charging adjustments
and capacity calculations.
Note: Lithium Batteries do NOT require a Temperature sensor.
Limiter Sensors (CT Sensors)
• Install sensors on incoming electrical service wires on L1 and L2 (see Diagrams Section)
• Limited To Home Mode (meter zero) and Peak Shaving Modes require CT sensors
• To ensure the sensors will fit, please check the wire size before ordering
• See pg. 39 for additional CT sensor information.
GEN Start Signal (Two-Wire)
• The signal comes from a normally open relay that closes when the Gen Start state is active
CANbus & RS485
• To connect batteries to the Sol-Ark 15K via RJ45, you need to splice the end connecting to the Sol-Ark 15K
• Use the middle two conductors
• RS485 is SunSpec draft 4 (will not work with draft 3)
Wi-Fi Antenna (Dongles)
Remote monitoring and software updates require an internet connection through the Wi-Fi dongle
Sensor Pin Out (Located in Sol-Ark user area)
(1,2) Batt Temp: Batt Temp Sensor has no polarity; used for voltage correction when using lead acid batteries
(+3, -4) CT1 & (+5, -6) CT2: Current transformers used for limited to home mode and peak shaving; Polarity matters
(7,8) Gen Start Relay: Two wire start for generators, simple open or closed relay
(9,10) Gen On Relay: Not currently in use
(11 B, 12 B) Emergency Stop: Short these pins to initiate emergency stop. This will shut down AC output from the
inverter and initiate rapid shutdown of the PV.
(+, -) Optional 12V input signal for RSD; Not Currently in use
(+15, -16) 12V power supply for RSD transmitters: such as TIGO; Rated for a maximum of 1.2W (100mA @12V)
