Check Communications Card Firmware
The Communication Card firmware must be 2.06 or higher.
A Communication Card with firmware 0.05 or higher can be updated using SP LINK.
To check and update the firmware if required, follow the steps below:
Note: Each battery type has a different power ON procedure. If the correct procedure for a given
battery type is not followed, the battery may not turn ON and run.
1. Connect the DC power to the SP PRO. This is done as follows:
For Sonnenschein@home – Leave the system DC circuit breaker or fuses OFF and turn
the battery ON by pressing the ON button (adjacent to the fuse holder). When the relay
inside the battery clicks, indicating the batteries have come ON, turn ON the system DC
breaker or fuses.
For LG Chem RESU – Turn ON the system DC breaker or fuses to the SP PRO then turn
ON the battery bank circuit breaker(s).
For Pylontech US2000 – Turn ON the battery by switching the On/Off switch to the ON
position.
For BYD B-Plus 2.5 modules, BYD B-Plus 13.8 BYD B-Plus 15.5, turn ON the battery bank
by pressing the ON button. Turn on the Pre-charge / Battery Sense (If the system is AMP)
and wait until the SP PRO comes on, then turn on the Battery Breaker or switch.
For LG Chem Rack Mount – Turn ON the system DC breaker or fuses to the SP PRO then
turn ON the battery bank by pressing the ON button.
Wait until the front panel LEDs are stable.
NOTE:
a. During the SP PRO power up, the front panel display cycles through three stages. First, all LEDs turn
green from bottom up, second, all LEDs turn red from bottom up and third, some LED’s will be flashing
while the battery LEDs are ON solid green. The third stage is what is referred to as stable.
b. Perform the following tasks quickly as the batteries might shutdown in 5-10 minutes without the
CANBUS communications. If this happens, turn the batteries ON and restart the process.
2. After the SP PRO has powered up and the front panel LEDs are stable, check the green LEDs on
the blue or black comm card.
The right LED should be steadily ON.
The left LED should be ON or flash approximately once per second.
3. Start Selectronic SP LINK.
