Growatt BMS Status

Your Growatt BMS status shows a resting voltage of 49.9V, 0.0 A current, and 0.00 KW power, with N 1 indicating a single battery module or an active node ID, but the state of charge indicator reads an ambiguous or low value while current flow has stopped. [1, 2]

Meaning of Your Status Screen

V 49.9V: The total voltage of your battery pack is 49.9 volts. For a 48V nominal lithium-ion battery, 49.9V is a low-to-moderate resting or nominal level, close to empty or standard low charge depending on your chemistry.
A 0.0 A / W 0.00 KW: The battery is completely idle. No current is going in or out.
N 1: Node 1 or module address 1 is online in the BMS communication chain. [1]

Quick Troubleshooting Steps

Check Communication: Ensure the CAN or RS485 communication cable between the battery BMS and the Growatt Inverter is firmly plugged in. [1]
Verify Settings: Check that your inverter battery type (Program 05/36) matches your lithium battery protocol (e.g., proper CAN/RS485 lithium code). [1]
Inspect for Fault Lockout: A 0.0A reading when loads are on often means the BMS internal MOSFETs have tripped open due to a low-voltage or over-current protection event. [1]
