Time not synchronised in the last 24
hours. Router has been switched off/
reconfigured.
No connection between inverter and Ohm-
pilot. Inverter switched off. The Ohmpilot
also needs a connection to the inverter at
night. Router switched off/faulty/reconfigu-
red. Night switch-off function enabled on
the inverter. Poor WLAN connection bet-
ween inverter or Ohmpilot and router.
Ambient temperature too high (>40 °C).
The output of the heating element is too
high Ventilation slots are covered.
Ambient temperature too low (<0 °C).
N and L mixed up.
Thermostat on heating element has swit-
ched off. Safety thermostat (STC) on the
heating element has triggered.
Heating element power is lower than sur-
plus power.
Load and generation fluctuations require a
few seconds to settle down.
Thermostat on heating element has swit-
ched off. Heating element is not connec-
ted.
After a power failure, if it does not receive
an IP address after 40 seconds, the Ohm-
pilot automatically assigns a fixed IP
address to 169.254.0.180 (only valid if the
Ohmpilot is connected to the router via
WLAN).
Check connection bet-
ween Ohmpilot and inver-
ter. Switch on router.
Check network settings.
Check connection. Switch
on the inverter. Update
the software. Switch Ohm-
pilot and inverter off and
on again. The night
switch-off function of the
inverter must be disabled.
On the inverter display,
set night mode to ON
under "SETUP/Display
Setting/Night Mode"
menu. Switch on router.
Reposition the WLAN
antenna in a better loca-
tion. Check network set-
tings.
Install Ohmpilot in a coo-
ler location. Use a heating
element with a permissi-
ble output. Uncover the
ventilation slots.
Install Ohmpilot in a war-
mer location. Installation
outdoors is not permitted.
Connect N and L cor-
rectly.
Wait until the thermostat
switches on again. Reset
the safety thermostat.
Select a larger heating
element where necessary
Briefly turn up the thermo-
stat for the power measu-
rement. Connect the hea-
ting element.
Restart Ohmpilot so that
the WLAN connection is
re-established.
