Hi Everyone,

I will be self-adding two PowerPro batteries to my new-ish Sol-Ark 15k system that currently has no batteries. I have enough professional experience with HV DC batteries (200V+) to know it is important to get the order of operations right.

Before connecting anything, I will set the ID of the Master battery to 64, turn it on, and select the "P03-SLK" protocol. Then I will set the ID back to 1 and then power off the battery.

I'll wire one PowerPro to each of the battery connections on the 15K.
I will connect one battery comms cable between them. Question: It looks like this is just a straight-through Ethernet cable (twisting 1&2 and 7&8)?
I will connect a comms cable (CAN) from the Master battery [CANH: 4, CANL: 5] to the Sol-Ark [CANH: 4, CANL: 5]
I will set the ID of the Master battery to ID 1 and the Secondary battery to ID 2.
I will set “BMS Lithium Batt 00” on the 15K

Question: Do I set the Sol-Ark battery enable before or after I connect and power on the battery?

Question: Is this sequence correct?
  1. Power Off 15k (AC breakers/disconnects off, PV DC disconnect off, power button off, battery breaker off)
  2. Make battery connections
  3. Sol-Ark Battery Breaker ON
  4. Press the power button on the Sol-Ark
  5. Turn the PV DC disconnect switch on the outside of the Sol-Ark ON
  6. All 15k AC breakers / disconnects (“GRID”, “GEN” and “LOAD”) ON
  7. Master Battery Breaker ON
  8. Master Battery Power Button ON
  9. Secondary Battery Breaker ON
  10. Secondary Battery Power Button ON
Thanks!
