I just had an alarm via VRM that the newly installed MPPT RS450/100 which has been operating perfectly for a few days is now not charging the battery and is showing the following error:
|Solar Charger - MPPT 450/100 HQ2142HTVCQ ||Automatic monitoring||Error code: #200 - Internal error|
The rest of the system is working fine although my customer has persistent bleeping from the unit.
Brief overview of system:
Pylontech US3000C x 7 modules
MPPT RS 450/100
3.4kw of PV in two strings
Can the fault be addressed remotely, will it need a visit or is it a warranty claim?
Any advice gratefully received as I cannot find this error code listed elsewhere
