===== ✅ Step-by-Step Fix and Diagnostics =====
# Verify Battery Voltage - Use multimeter at the battery bank terminals (RELiON): confirm ≥12.8V. - If voltage <12V: charge externally via 120V charger or vehicle alternator until full.
# Check BMPro Main Power Feed - Locate the BMPro “Node” or “Power Distribution Module” (usually near fuse box or behind main cabinet). - Test for 12V input to the unit with the multimeter. - If no 12V present: trace back to inline fuse or 12V cutoff relay — replace fuse or confirm relay is closed.
# Check for Blown Fuse at BMPro System - There’s typically a dedicated fuse labeled “Control” or “BMPro” — verify continuity or replace with known good 10A fuse.
# Reset the Lithium Batteries - For RELiON InSight batteries: - Locate the power button (often hidden on the end panel). - Hold for 3–5 seconds to initiate wake cycle. - LED indicator should turn green (if not, consult InSight manual for internal BMS fault).
# BMPro Touchscreen or App Soft Reset - Hold the touchscreen power button (if equipped) for 10 seconds. - If using a remote key fob or app module (Node BLE), open/close the entry door 3x within 15 seconds to trigger wake command.
# Pull Battery Disconnect for 5 Minutes - Open battery compartment. - Disconnect negative battery terminal (or use master disconnect if installed). - Wait 5 minutes — reconnect — check if BMPro initializes.
# Manually Power the BMPro Panel - If accessible, apply 12V to the BMPro panel's input wire directly (bypassing fuse temporarily for test purposes). - If panel lights up: wiring/fuse issue confirmed.
# Check DC-DC Charger and Solar Controller Wiring - Verify solar controller isn’t backfeeding erroneous voltage into system signal wires. - Disconnect temporarily if system appears unstable.
