Cause / Solution
This error will not auto-reset.
Power terminals overheated, check wiring and
fasten bolts if possible.
This error will auto-reset.
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-organise
panels.
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 controller is probably
faulty.
This error will auto-reset.
To protect the battery from over-charging the
panel input is shut down. To recover from this
condition first disconnect the solar panels and
disconnect the battery. Wait for 3 minutes
reconnect the battery first and next the panels.
If the error persists the charge controller is
probably faulty.
Communication with one of the paralleled
controllers was lost. To clear the warning,
switch the controller off and back on.
The controller is being paralleled to another
controller 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.
Connection to the BMS lost, check the
connection (Cabling / Bluetooth link). When
the charger needs to operate in stand-alone
mode again, change to setup menu setting
'BMS' from 'Y' to 'N' (setup item 31).
This error will reset after the CPU has cooled
down.
If the error persists, check the ambient
temperature and check for obstructions near
the air inlet and outlet holes of the charger
cabinet.
Check manual for mounting instructions with
regard to cooling. If error persists the controller
is probably faulty.
This error will not auto-reset.
This error will not auto-reset.
Restore defaults in the setup menu (setup item
62).
Disconnect the charge controller from all
power-sources, wait 3 minutes, and power up
again.
