MPPTs cycling on and off with 'fault' state
Hi @chasemaritza. What is the reported error? 'Notifications' should show it.
HI @JohnC does not give me any error Notifications! only give fault for a second and does it the hole day
Hi @chasemaritza,
This can sometimes occur when there is a fault reported by the BMS of a managed battery, and it is trying to control the MPPTs by telling them to turn off due to over voltage. The MPPTs show the fault, but it may be originating elsewhere in the system.
Please check your batteries and report back to make sure that they are operating properly without any errors or alarms that might be signalling to stop charging by the MPPTs.
hi @Guy Stewart (Victron Community Manager) battery is all good and happy i have check all float voltages but still it goes into the error state and pulls down the pv power
Can you please post the Vrm site id so I can have a look and see what else it might be?
Hi @chasemaritza,
I had a look at the system, for some reason the DVCC combined charge current limit has been set to 1A on the GX device.
I have not made any changes, There may be other reasons why the installer has chosen to set this. But I suspect if you disable this Limit Charge Current your MPPTs will have a chance to perform normally.
hi @Guy Stewart (Victron Community Manager) i have made the change and will check if the mppt`s preform normal and let you know what the out come is
Hi thanks for checking i have made the change but not successful ill be checking all connection tomorrow
do you have by any chance also have a VE.Smart network over bluetooth configured with the mppt's
