Gents,
I swapped a Sunny Boy SB1700 which stopped working, with a Sunny Boy SB2000HF-30 which came from another plant. The SB2000 ws working when it was decommissioned.
But now I added it into my plant, but it does not start. I only see the blue led turning on and I can access it with blue tooth in Sunny Explorer. But is stays in the off models. Everything is plugged in correctly, triple checked. I measured the DC into, 241 V DC. Please advise...

It is probably saying ADJ rather than AD0, but your installer should be able to adjust it with a grid guard code
