48v Growatt SPF 3000TL and LifePo4 Battery problem

[sunshine_eggo]

I just used a wrench and did them really tight, my wrench didnt go low enough. I ordered a new torque wrench that will work. If the bolts are tight but not torqued right how does that cause a problem?

loose connections cause horrible problems. An effort to tighten them should eliminate most of the issues. Proper torque ensures solid connections.

Moments prior to disconnect, what is:

Battery 1 voltage:
Battery 2 voltage:
Inverter reported voltage:

Does inverter reported voltage agree with voltmeter?
