current”
Although this will not cause an immediate defect, the heat
sink will become very hot and could cause injury. The load
is disconnected in order to avoid further self-heating. After
the current has decreased, the load will be reconnected
automatically and the error message disappears.
nominal currents. The system must
be split into smaller PV arrays units
on separate System-Managers.
“load current”
•
The load current is too high and the output is
disconnected. Either the whole consumption exceeds
the max. discharge currents or the max. pulse currents
were exceeded by using high surge appliances.
•
A short circuit has been caused. After the problem has
been solved, the System-Manager reconnects the load
about 30 seconds later.
•
Switch off some loads by hand
•
Clear the short circuit
“over
temperature”
The maximum allowable temperature has been exceeded.
In order to reduce further heat generation the loads are
disconnected automatically. As soon as the System-
Manager has cooled down, normal operation will resume.
•
Check the ventilation at the back heat
sink and clean it if necessary
•
Protect the System-Manager from
direct sunshine
•
Reduce warming caused by
appliances near the System-Manager
•
Reduce the loads or PV modules.
“over voltage”
In particular, the recharge process through back-up
generators or chargers tied directly to the battery causes
voltages which are harmful for some appliances. Therefore
these loads are disconnected when high battery voltages
are present.
•
Disconnect external chargers
•
adjust external chargers for less
voltage
“low voltage”
To protect the battery, all loads powered by the System-
Manager will be disconnected. They will be reconnected
automatically after the battery voltage has reached the load
reconnecting level.
•
Reduce loads or hours of operation of
loads to keep the battery from being
discharged deeply, or increase solar
array to add energy to the system
•
Connect all loads through the
System-Manager to avoid strong
discharge of the battery
No module is connected, otherwise module, module internal
blocking diodes, or array is defective.
•
Check contacts and junctions
“no module”
no module is connected but there is no detection of “no
modul”
•
disconnect both wire (M+ and M-) at
the terminal of the regulator
•
wait up to 1 hour
“EEProm
defect”
The EEPROM memory chip inside of the System-Manager
cannot be read or accessed any longer by the System-
Manager’s circuitry.
•
Disconnect the System-Manager and
reconnect it in the order described. If
the indication remains, the System-
Manager must return to the dealer for
repair.
“self test
failure”
The self-test could not be carried out correctly, since the
solar PV array or the load was not disconnected, or one of
the components in the System-Manager is defective
•
Disconnect all components, except
the battery and try again.
•
If the self-test still failed, the System-
Manager should be sent to the dealer
for service.

10 Legal Guarantee
In accordance with German statutory regulations, there is a 2-year legal guarantee on this product for the customer.
The seller will remove all manufacturing and material faults that occur in the product during the legal guarantee period
and affect the correct functioning of the product. Natural wear and tear does not constitute a malfunction. Legal
guarantee does not apply if the fault can be attributed to third parties, unprofessional installation or commissioning,
incorrect or negligent handling, improper transport, excessive loading, use of improper equipment, faulty construction
work, unsuitable construction location or improper operation or use. Legal guarantee claims shall only be accepted if
notification of the fault is provided immediately after it is discovered. Legal guarantee claims are to be directed to the
seller.
