Hi,
New system. After solving some initial problems I now have this. I have 2x200ah NG batteries with Lynx BMS NG. Batteries were fully charged and I set it to run in inverter only mode with a 60w load. After a few hours SOC was 96% and a Low battery alarm occured causing shutdown. The graphs show the DC voltage was 13.29 immediately prior to the alarm.
It’s not really making sense… any ideas please?
Is this a fixed installation or mobile?
Do you have ess?
Sometimes a low battery warning can come from the dynamic cut off set in ess
What inverter settings are configured? There are various cutoffs that need to be correctly configured.
Hi Lx
No it is going in and RV. I have multiplus 2, NG batteries and lynx BMS NG.
Hi Nick,
Sorry I am new to this. Where would I find these, are they in the console and which ones are of interest? The distributor has been looking at the system for a different fault which is now clear. He tells me the system has been preconfigured …..
You need to either use a mk3 usb adapter and victron connect or veconfigure, or remotely pull the config via VRM if the system is online via a GX.
I would suggest you brush up on how to configure inverters, there is free training on professional.victronenergy.com.
Inverters should be appropriately configured prior to use.
You should also check voltage drop on your wiring between the batteries and the inverter. The batteries may say 96% and 13.3V but if your wiring is poor the inverter could well be seeing a lot less than this. Put a load on the ac output of the inverter and measure the voltage at the battery terminals and the DC terminals on the inverter.
I believe the wiring is sound. Problem I have is that the BMS won’t close the contactor now. Having been through it with the distributor they think the BMS is faulty and have asked me to start the return process.
Thanks Nick I will take a look at the material.
Update. The BMS was returned to the distributer. After waiting a couple of weeks they have confirmed the BMS is faulty and are sending a new unit to replace. They did say that Victron had authorised the replacement so I suspect this played some part in the delay. Anyway I will be happy when the replacement arrives and the problem is resolved. Fingers crossed.
