6.3.1.8 Error 20 - Maximum Bulk-time
exceeded
Solar Chargers
The maximum bulk time protection is a feature that
was in the chargers when they were just released
(2015 or earlier) and later the feature was removed.
If you do see this error, then update to the latest
firmware.
If you then still have the error, perform a reset to
factory defaults of the configuration, and reconfigure
the solar charger.
AC Chargers
This protection is default enabled on the Skylla-i and
the Skylla IP44.
This error is generated when the battery-absorption-
voltage is not reached after 10 hours of charging.
The feature of this safety protection is to detect a
shorted cell; and stop charging.
6.3.1.9 Error 21 - Current sensor issue
This error will not auto-reset.
Disconnect all wires, and then reconnect all wires.
Also, make sure the minus on the MPPT charge
CCGX (PV minus/Battery minus) is not bypassing
the charge CCGX.
If the error remains, please contact the dealer, there
might be a hardware defect.
6.3.1.10 Error 26 - Terminal overheated
Power terminals overheated, check wiring, including
the wiring type and type of strands, and/or fasten bolts
if possible.
This error will auto-reset.
6.3.1.11 Error 28 - Power stage issue
This error will not auto-reset.
Disconnect all wires, and then reconnect all wires. If
the error persists the charge CCGX is probably faulty.
Note
This error was introduced in v1.36. When doing an
update, it might look like the firmware update caused
this issue; but it doesn't. The Solar charger was then
already not performing 100% before the update;
updating to v1.36 or later merely made the issue more
visible. The unit needs to be replaced.
6.3.1.12 Error 33 - PV over-voltage
This error will auto-reset after PV-voltage has
dropped to safe limit. This error is an indication that
the PV-array configuration with regard to open-
circuit voltage is critical for this charger. Check
configuration, and if required, re-organize panels.
6.3.1.13 Error 34 - PV over-current
The current from the solar-panel array has exceeded
75A. This error could be generated due to an internal
system fault. Disconnect the charger from all power-
sources, wait 3 minutes, and power-up again. If the
error persists the CCGX is probably faulty, contact
your dealer.
6.3.1.14 Error 38, Error 39 - PV Input shut-
down
To protect the battery from over-charging the panel
input is shorted.
Possible reasons for this error to occur:
– The Battery voltage (12/24/48V) is set, or auto-
detected, incorrectly. Use VictronConnect to
disable auto-detect and set the Battery Voltage to
a fixed voltage.
– There is another device connected to the battery,
which is configured to a higher voltage. For
example, a MultiPlus, configured to equalize at 17
Volts, while in the MPPT this is not configured.
– The battery is disconnected using a manual
switch. Ideally the charger should be switched off
before disconnecting the battery, this avoids a
voltage overshoot on the charger output. If
necessary, the voltage trip-level for the PV Short
protection can be increased by raising the
Equalization voltage set-point (note: equalization
does not have to be enabled in this case).
