Overvoltage
The voltage exceeded the set level
for a predefined duration.
Load rejection while voltage was
already on a high level.
Activate load rejection detection.
Increase the controller parameters.
Use adaptive controller parameters.
Add an additional external capacitor.
After consultation with Top-Con support, where
appropriate, increase the error delay.

Overvoltage
The voltage exceeded the set level
for a predefined duration.
Controller overshooting
Decrease controller parameters - possibly increas-
ing the proportional part (P Gain).

Overvoltage
The voltage exceeded the set level
for a predefined duration.
Overshooting caused by set value
steps.
Reduce the gradient of the set value ramp.
Reduce controller parameters.
Overshooting in open loop: use adaptive Control-
ler pa-rameters.

Max. sense voltage
drop reached
The difference of module voltage
minus sense voltage has exceeded
the set limit for a specific duration
(delay).
The difference of module voltage
minus sense voltage has exceed-
ed the set limit for a specific dura-
tion (delay).
Adapt the detection level and delay to actual con-
ditions. Possibly deactivate the detection if it is not
necessary
Use low resistance load feed cable.
Don’t disconnect the load feed cable.

TC.LIN Overvolta-
ge
The TC.LIN output voltage exceeded
the over voltage limit for a specific
duration.
The TC.LIN output voltage ex-
ceeded the over voltage limit for a
specific duration.

Sense polarity
TopCon has sensed a negative
sense voltage!
Reverse Polarity error.
Connection with reversed polarity
Check the polarity of sense wires and polarity of
the power cords.

RPP-Voltage un-
stable
TopCon had multiple faults keeping
the output voltage in preconfigured
limits. This is necessary to be able to
switch the RPP switch
Voltage holding level too low. Ex-
treme controller pa-rameter that
led to oscillation.
Adjust controller parameters, increase the limits
Perhaps parameter adjustment after contact with
manufacturer.

RSC: Sense voltage is over the de-
fault value to switching the Relais for
configuration the switch box.

Disconnect battery or wait for discharging capaci-
tors.
