– The battery is disconnected using a Lithium
charge relay connected to the “allow-to-charge”
output of a BMS. Consider wiring this signal to
the Remote terminal of the charger instead. This
shuts down the charger gracefully without
creating a voltage overshoot.
Error recovery:
– Error 38: First disconnect the solar panels and
disconnect the battery. Wait for 3 minutes, then
reconnect the battery first and next the panels.
– Error 39: The charger will automatically resume
operation once the battery voltage drops below its
maximum voltage setting (normally Equalization
or Absorption voltages), for 250V versions or
float voltage for the other units. It can also take a
minute to reset the fault.
If the error persists the charge CCGX is probably
faulty.
6.3.1.15 Error 40 - PV Input failed to shut-
down
If the charger is unable to turn off the PV input, it will
go into a safe mode in order to protect the battery
from over-charging or having a high voltage on the
battery terminals. In order to do that, the charger will
stop charging and disconnect its own output. The
charger will become faulty.
Information 65 - Communication warning
Communication with one of the paralleled CCGX
was lost. To clear the warning, switch the CCGX off
and back on.
Information 66 - Incompatible device
The CCGX is being paralleled to another CCGX that
has different settings and/or a different charge
algorithm.
Make sure all settings are the same and update
firmware on all chargers to the latest version.
6.3.1.16 Error 67 - BMS Connection lost
The charger is configured to be controlled by a BMS,
but it does not receive any control messages from a
BMS. The charger stopped charging, as a safety
precaution.
Check the connection between the charger and the
BMS.
How to reset the charger, to de-couple it from
the BMS
When the charger needs to operate in stand-alone
mode again, not controlled by a BMS, it needs to be
reset:
– VE.Can solar chargers, go into the setup menu,
and change setting ‘BMS’ from ‘Y’ to ‘N’ (setup
item 31).
– VE.Direct solar chargers, reset the charger to
factory defaults with VictronConnect, and then
reconfigure it.
Note
(Solar-)chargers automatically configure themselves
to be BMS-controlled when they are connected to
one; either direct or via a CCGX.
6.3.1.17 Error 68 - Network misconfigured
The charger detects multiple conflicting network
sources trying to take control of the charger.
Applies to SmartSolar MPPTs and SmartSolar
MPPTs VE.Can.
The typical reason for the error to show is that the
charger is configured to operate in parallel using our
wireless VE.Smart protocol and at the same time it is
part of an ESS or it’s used in an installation with an
intelligent battery. In all those cases, the charger is
being externally controlled (by ESS and/or intelligent
battery) and should therefore not at the same time be
configured for parallel operation.
The error might be intermittent as the charger will
always try to reset the fault. There is a 10 second
delay to retry resetting the error in order for the error
to be seen and broadcast to the interfaces.
Resolution: disable the parallel operation by
connecting VictronConnect, going to settings, then
“VE.Smart networking” and choose “Leave
network”.
For SmartSolar MPPT VE.Can only, also make sure
it’s not connected to a CCGX via both VE.Can and
VE.Direct. Either disconnect the VE.CAN cable or
the VE.Direct cable.
Once the conflict is resolved the error will disappear
and the charger will resume normal operation within
a minute.
