The Victron investor-loaders (MultiPlus, MultiPlus-II, Quattro<\/a>) report faults in two ways: by means of the Front LED<\/strong> and, if there is a GX device (Cerbo GX, Ekrano GX), via a VE.Bus error code<\/strong> visible on the GX screen, in VRM and in VictronConnect. This guide covers both and adds error code #67 relating to communication with the BMS.<\/p>\n\n\n\n

LED alarms (without the GX device)<\/h2>\n\n\n\n
LED<\/th>Status<\/th>Reason<\/th>What to do<\/th><\/tr><\/thead>
Low battery (flashing)<\/td>Notice<\/td>The battery voltage is approaching the cut-off threshold<\/td>Reduce the load or charge the battery (solar, mains, generator)<\/td><\/tr>
Low battery (permanent)<\/td>Off<\/td>Voltage below the DC cut-off (default 9.3 \/ 18.6 \/ 37.2 V)<\/td>The inverter restarts when the voltage rises. If this happens every night, the battery is undersized or at the end of its life.<\/td><\/tr>
Overload (flashing)<\/td>Notice<\/td>Fuel consumption close to maximum power<\/td>Collect parcels<\/td><\/tr>
Overload (fixed)<\/td>Off<\/td>Overload or short circuit at the AC output<\/td>Switch off all loads, restart the system and switch them on one by one. Take care with motor and compressor start-ups (3\u20135 times their rated current)<\/td><\/tr>
Temperature (flashing)<\/td>Notice<\/td>High internal temperature<\/td>Improves ventilation; leave a 10 cm gap all round<\/td><\/tr>
Temperature (fixed)<\/td>Off<\/td>Overtemperature<\/td>Wait for it to cool down; if the fan isn\u2019t turning, contact SAT<\/td><\/tr>
Low battery + Overload (alternating flashes)<\/td>Off<\/td>DC ripple too high<\/td>Battery cables that are too long or too thin, or loose terminals. Check the connections and tighten them<\/td><\/tr>
Fixed Bulk + Absorption + Float<\/td>Blockade<\/td>Internal error<\/td>Restart. If the problem persists, contact support<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

With VictronConnect (Bluetooth via the VE.Bus Smart Dongle or MK3-USB cable), you will be able to view these alarms as text messages, along with the history.<\/p>\n\n\n\n

VE.Bus error codes (with GX)<\/h2>\n\n\n\n
Code<\/th>Meaning<\/th>Solution<\/th><\/tr><\/thead>
VE.Bus error 1<\/td>A device has lost communication in a parallel\/three-phase system<\/td>Check the RJ45 cables between units (they must be straight-through CAT5 cables, not crossover cables) and ensure that none of the units are switched off<\/td><\/tr>
Error 2<\/td>New unit detected or unit removed<\/td>Run VE.Bus System Configurator or VE.Bus Quick Configure again<\/td><\/tr>
Error 3<\/td>Not all devices are present, or they are not all configured in the same way<\/td>Configure all units using the same file and the same firmware version<\/td><\/tr>
Error 4<\/td>There is no more than one device on the bus (the system is configured as parallel, but only one is visible)<\/td>Cables or power supply for the second unit<\/td><\/tr>
Error 5<\/td>Overvoltage at the AC output<\/td>It is usually a problem with a single unit; replace<\/td><\/tr>
Error 6<\/td>Error in the DDC programme<\/td>Restart; if the problem persists, contact SAT<\/td><\/tr>
Error 7<\/td>Slave drive with different firmware or from a different generation<\/td>Update the firmware so that they all match<\/td><\/tr>
Error 8<\/td>Incorrect bus hardware or cabling<\/td>Check RJ45 connectors and terminators<\/td><\/tr>
Error 9<\/td>Internal communication failure<\/td>SAT<\/td><\/tr>
Error 10<\/td>System synchronisation failed<\/td>Restart all units at the same time<\/td><\/tr>
Error 11<\/td>Mains or battery relay not found \/ ripple problem<\/td>Loose AC-in wiring or unsuitable DC cables<\/td><\/tr>
Error 12<\/td>Incorrect system configuration<\/td>Reconfigure using System Configurator<\/td><\/tr>
Error 14<\/td>Device installation error<\/td>Reconfigure or update the firmware<\/td><\/tr>
Error 15<\/td>AC output overcurrent<\/td>Overload in a phase or unit<\/td><\/tr>
Error 16<\/td>Output voltage out of range<\/td>Check that all units are set to the same voltage (230 V)<\/td><\/tr>
Error 17<\/td>Phase loss \/ master unit not connected<\/td>In a three-phase system, one phase is missing: cables or unit switched off<\/td><\/tr>
Error 18<\/td>AC output overvoltage<\/td>Load with energy recovery (motor, other inverter); check the installation<\/td><\/tr>
Error 22<\/td>This device cannot operate as a slave<\/td>Settings: switch between master and slave<\/td><\/tr>
Error 24<\/td>System switching protection<\/td>Restart<\/td><\/tr>
Error 25<\/td>Incompatible firmware<\/td>Update<\/td><\/tr>
Error 26<\/td>Internal ruling<\/td>SAT<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

General rule: in parallel or three-phase systems, All units must have the same firmware and the same configuration file<\/strong>. Most errors 1\u20134 and 7 are caused by failing to comply with this.<\/p>\n\n\n\n

Error #67: BMS connection lost<\/h2>\n\n\n\n

This appears in Cerbo GX when CAN communication with the BMS of a managed battery has been lost (Pylontech, Pytes, ZYC, BYD LV, Victron, Lynx BMS). With DVCC active, the inverter and MPPT units stop charging for safety reasons.<\/p>\n\n\n\n
