Messages

Many event messages indicate a fault in the grid. They are not operational faults of the device. The triggering levels are
defined in standards, e.g. VDE0126-1-1. The device shuts down if the values exceed or fall below the approved levels.

Status & Fault messages
The overview of all existing status & fault messages, can be found in the associated integration manual, which
you can obtain from KACO sales team (pv-projects.kaco.de@siemens.com).

Explanation/remedy
The measuring elements of the device have been selected to
ensure maximum yields. Due to these tolerances, the daily
yields shown may deviate from the values on the feed-in meter
by up to 15%.
› No action.
The PV generator voltage or power is not sufficient for feed-in
(solar radiation is too low). The inverter checks the grid para-
meters before the feed-in process begins. The length of time it
takes to switch back on again differs from country to country,
depending on applicable standards and regulations, and may
be several minutes. The starting voltage may have been set in-
correctly.
› Adjust starting voltage in the Parameter menu.
› No action
The device has reduced its power to prevent damage due to
excessive temperatures inside the device. Note the technical
data. Ensure that the convection cooling is not impeded from
the exterior. Do not cover the cooling fins.
› Ensure sufficient cooling of the device.
› Remove any foreign bodies which are present on the unit.
› Clean the cooling fins
A generator string is disconnected from the device owing to a
faulty fuse. Check why it has tripped by measuring all DC
strings using a clip-on ammeter. - If there is no current flow in a
string, the associated DC fuse is faulty.
› Check the no-load voltage and dimensioning of the PV gener-
ator. Replace the damaged modules if necessary.
› Replace the PV fuse with a fuse of the same size and type.
Explanation
– Fault signal relay has been tripped.
– Feed-in was ended due to a fault.
– The fault relay releases again.
– The device feeds back into the grid again after a country-
specific time period.
