Hi Jason,
Did you resolve the High Battery Voltage alarms? I got the same alarms after updating to v3.42 and still seeing them on v3.50 (Colour Control GX). With v3.50 the PV Inverters now appear in the device list and display on the dashboard and CCGX display.
Thanks
Hi @BC24 , I checked your system, and it has 47 high voltage alarms in the logs and first one dates back to April 27th 2024.
Definitively something you need to look into but I don’t think this is related to a GX firmware update.
That high battery voltage alarm is actually a high cell voltage alarm, sent by the BMS.
Most likely cause, first thing to check, is cell imbalance, which in itself is not a problem and normal to occur of the battery doesn’t have the option to sufficiently and often enough do the balancing. But it does need resolving to be able to have maximal usable capacity of your battery.
How to do that is documented in detail here: Victron & BYD [Victron Energy]
Hi Matthias
Thanks for checking and you response. I can enlarge on why I suspect a firmware issue. In April 24 I added additional panels, solar chargers and two additional BYD LVS modules. So it does make sense there could be a battery imbalance. However: At the time I had three existing solar chargers connected through a USB hub to the CCGX working well on firmware v2.51. The installer attempted to connect two additional solar chargers along with the existing three solar chargers (all Victron smart solar) through a new larger usb hub. It didn’t work and one of the changes we tried was a ccgx firmware update (don’t recall the version). I persisted with this firmware for a day (27 April) but it didn’t make any difference with the solar chargers and I lost PV inverter monitoring with it so went back to v2.51 on the ccgx. Solved the solar charger issue by reverting back to the original USB hub and connected the two new solar chargers using VE direct about two weeks later (you can see the solar charger error codes vanish on 14 May and no battery voltage alarms after 27 April). Got to October and the additional solar production started to exceed my grid feed in limit of 10kW so I updated the ccgx firmware to v3.42 at the time to utilise the grid feed in limit function. High battery voltage alarms appeared straightaway along with the loss of PV inverter monitoring as previously posted. I reverted back to v2.51 and the high battery voltage alarms disappeared but I went back to exceeding my grid feed in limit. Updated to v3.50 and PV inverter monitoring was restored but high battery voltage alarms returned. So there appears to be a link to ccgx firmware updates.
I will work through the information you supplied and see if that helps.
One other issue that I haven’t resolved is that none of the individual solar chargers show up in the device list on the VRM portal. On v2.51 the solar chargers show up with individual IDs 289, 290 etc but on v3.50 I just get one with ID of 65535. All solar chargers updated to latest firmware, power cycled and ccgx rebooted. Do you have any recommendations to try here.
Thanks
Ben
Hello all,
I have 2x BYD Premium LV battery (30kWh in total) and when SoC is close to 100% I also get high cell voltage warnings (not errors !).
The highest cell voltage can get up to 3.8V (if I’m not mistaken) but overall battery voltage stays within spec.
So I’m not sure if this is a Victron issue or a BYD issue.
