What this video covers
Troubleshooting a Victron battery monitor requires verifying the shunt installation and programming parameters to ensure accurate state-of-charge readings. The shunt must be wired so that only the battery bank connects to the battery side, while all loads, chargers, and chassis grounds connect to the system side.▶ 1:19 If the shunt is installed in reverse, the Victron Connect app allows users to toggle the current measurement direction to "reverse" without rewiring.▶ 3:51 Programming errors often stem from an incorrectly set charged voltage; the rule of thumb for a 12-volt system is to set the charged voltage 0.2 volts below the charger's absorption voltage.▶ 6:12 When the monitor displays a double-dash symbol after a power reset, it indicates the device lacks a confident state-of-charge reading.▶ 7:00 Users can configure the "battery state of charge on reset" setting to "clear" or "keep state of charge," though "clear" is preferred to avoid inaccurate guesses after long periods of inactivity.▶ 7:14 Charging the battery bank to the full absorption voltage via shore power will reset the monitor to 100%.▶ 10:55
