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. 35 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 5K via RJ45, you need to splice the end connecting to the Sol-Ark 5K
Use the middle two conductors
RS485 is SunSpec draft 4 (will not work with draft 3)
Wi-Fi Antenna (Dongle)
Remote monitoring and software updates require an internet connection through the Wi-Fi dongle
Sensor Pin Out (Located in Sol-Ark user
(1,2) Batt Temp: Battery Temperature Sensor has
no polarity and is needed 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
(7,8) Gen Start Relay: Two wire start for
generators, simple open or closed relay
(9,10) Gen On Relay: Not currently used
(B 11, B 12) Emergency Stop: Short these pins to
initiate emergency stop. This will shutdown AC
output from the inverter and initiate rapid
shutdown of the PV.
(+13, -14) Optional 12V input signal for RSD
(+15, -16) 12V power supply for RSD
transmitters: such as TIGO and Midnite
Rated for a maximum of 1.2W (100mA @12V)
