Nov 12, 2023 · Quick question, that is, when a multiplus in DVCC reaches its shutdown, pre-alarm, restart voltage thresholds, what voltage source is triggering this, the DVCC voltage (ie. Bluesolar jumping bulk/absorption/float. There is a resource box on this page with linked manuals. Victron Energy is not liable for any consequential damages arising from the use of this product. My unit was parked with only refrigerator and normal parasitic draws for a few weeks. I checked and rechecked polarity and everything is correct. The Lynx Ion + Shunt will pre-charge the system before closing the safety contactor. I contacted Large difference between solar blanket voltage output and Victron dashboard. Batteries all have same Level of charge. They are large banks but only see brief loads and are also supported by a 24V alternator when cruising. Update: This was corrected with a firmware update. The Lynx Smart BMS is equipped with a pre-charge circuit. 90 V A configurable pre-alarm warns with a minimum delay of 30 seconds of an imminent shutdown of the loads as a result of an impending low cell voltage. Prevention is better and using a capacitor to pre-charge an inverter is a good thing. You mentioned in your post that the question is for paralleled batteries? If so, then pre-charging is not needed. This will pre charge capacitive loads such as inverters or inverter/ chargers before the contactor closes. It doesn’t send or logs any pre- alarms or warning. It simply opens the contactor and shuts itself off except bluetooh. This is fine the firmware is very similar so that is not an issue (since victron connect would have loaded it. Consider wiring this signal to the Remote terminal of the charger instead. It seems worth trying other battery brands, such as EG4, to see if they have better pre-charge circuits than the SOKs. Question is. Jun 22, 2024 · Given in this case it was done with low current from your pre-charge circuit, if they unit is now working (once you corrected the polarity), then it might be ok. Just wonder how to pre-charge the DC bus when first time connect to battery. When I plugged it in to 110 AC power to charge the battery, it initially worked, but then the BMS shut down as I had accidentally left default charge limit from factory at 25 amps on the JK. If you download victron connect there is a demo library that lets you set up products to practice or experiment with options and explore. Tip. " per "Master-LV-manual-EN-2. Nov 16, 2019 · The whole pre-charge thing is to address a theoretical risk. 54. May 31, 2021 · As already mentioned above, connect the nagative terminal and then pre-charge the capacitors inside the multiplus with a resistor e. , 2 x 5000KVa vs. Ideally this behavior would keep the cells below 3. Multiplus 12/3000/120 Overloads in Charge only Oct 31, 2024 · Dear all, I would like to ask you about some issues with our new lithium batteries (NG and NG Smart BMS). The alternator is feeding the thruster bank. Waited about five minutes but the inverter LED didn't come on (which I presume they should), and the Multiplus (Bus-connected) didn't show up in Victron Connect local). Instructions / remarks. When I connect the car and want to start the charging process on the wallbox, “starting” appears and after a few seconds the charging process stops. edtda vurlypyh jkeua gjuh vkib qyvfb ybav jhwbe ursh lvvt gbg jpgjbi jmdi tprhc wfopal
