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

•

CT winding default ratio is 2000:1; however, this ratio is programmable

•

To ensure the sensors will fit, please check the wire size before ordering

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 8K via RJ45, you need to splice the end connecting to the Sol-Ark 8K

•

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)
