Startup Phase and Grid Feed-in Mode
Startup Phase
The Fronius CL carries out a self test after being turned on automatically.
Then a test of the public grid is carried out.
This test takes five minutes. During the startup sequence the illumination
of the Operating Status LED is yellow.
Test Procedure
1. Segment test
All display elements light up for about one second.
2. Self test of essential inverter components
- The inverter goes through a master check list for several seconds
- The display shows ‘TEST’ and indicates the respective component
that is being tested (for example, ‘LED’)
3. Synchronization with grid
- ‘WAITPS’ is displayed, the inverter icon flashes: The inverter is
waiting for all power stage sets in the network to be on stand-by.
This procedure takes place dependent on the DC voltage.
-
Next, the display shows ‘SYNCAC,’ the grid icon flashes.
89
Test Procedure
(continued)
4. Startup test
- Before the inverter starts feeding energy into the grid, the conditions of the grid are tested in accordance with local regulations.
- The display shows ‘STARTUP.’
The startup test takes five minutes. The time elapsed is indicated by a
bar shrinking from the top down.
Whenever two scale divisions stop flashing and disappear, 1/10 of the
total duration of the test is over.

Energy supplied
Energy supplied during the monitored period (kWh / MWh)
Due to the variety of different monitoring systems, there can be deviations
between the readings of other metering instruments as compared to the
readings from the inverter. For determining the energy supplied to the
grid, only the readings of the calibrated meter supplied by the electric
utility company are relevant.
Yield
Money earned during the monitored
period (set currency and price per
kWh in setup menu)
As was the case for the energy supplied, readings may differ from those
of other instruments.
‘The Setup Menu’ section describes how to set the currency and rate for
the energy supplied. The factory setting depends on the respective country-specific setting.
CO2 reduction
CO2 emissions saved during the monitored period
(lb or T, pounds or tons)
The area for unit display switches between ‘lb,’ ‘T’ and ‘CO2.’

Status Diagnosis and Troubleshooting
Displaying
Status Codes
Your inverter is equipped with a self diagnostic system that automatically
identifies a large number of possible operation issues by itself and displays them on the screen. This enables you to know immediately if there
are any malfunctions in the inverter, the grid, the photovoltaic system or
any installation or operating errors.
Whenever the self diagnostic system has identified a particular issue, the
respective status code is shown on the screen.
Important Display of a status code for a short time may be the result of
the control procedures of your inverter. If it subsequently continues to
operate normally, there has not been a system error.
Normal Operation Status
Codes
The open circuit voltage of the
solar modules is too low.
As soon as the open circuit voltage exceeds 265 V, the inverter starts
synchronizing with the grid (display shows ‘SYNCAC’).
The total power output of the solar
modules is insufficient.
After a short time the inverter resumes grid synchronization (display
shows ‘SYNCAC’).
Total Failure
If the display remains dark for a long time after sunrise:
- Check the open circuit voltage of the solar modules at the connections
of inverter:
Open circuit voltage < 265 V ... Error in the photovoltaic system
Open-circuit voltage > 265 V ... may indicate a basic fault in the inverter. In this case, notify a Fronius-trained service technician.
131
Power Stage
Set Error
Status Codes
A special status code is triggered when there is an error in the inverter in
one of the power stage sets.
It is also possible to call up state messages even if there is no actual error
in existence. This form of status polling may be found in the section ‘The
Setup Menu.’
Display in normal operation
When there is an error in one of the
power stage sets, the display flashes between ‘STATE’ and the
corresponding status message
(e.g., ‘STATE 515’)
and
‘ENTER’
-
Press the ‘Enter’ key
-
The status display of the power
stage set with the error appears, e.g. ‘STDBY 00’
Press the ‘Enter’ key

Maintenance
Safety
WARNING! An electrical shock can be fatal. Danger from grid
voltage and DC voltage from solar modules.
- Never work with live wires! Prior to all connection and maintenance work, make sure that the AC and DC wires are not
charged.
- The connection area should only be opened by a licensed
electrician.
- Power stage sets should only be opened by Fronius-trained
service personnel.
- The DC main switch is only used to switch off power to the
power stage sets. When the DC main switch is turned off,
the connection area is still energized. A solar module
ground at the positive or negative poles still remains in
effect. Never touch the DC+ and DC-.
- These servicing instructions are for use by qualified personnel only. To reduce the risk of electric shock, do not perform
any servicing other than that specified in the operating
instructions.
WARNING! An electrical shock can be fatal. Danger from
residual voltage from capacitors.
You must wait until the capacitors have discharged. Discharge
takes 5 minutes.
CAUTION! An inadequate grounding conductor connection can
cause serious injuries to persons and damage to (or loss of)
property. The screws on the covers provide an adequate grounding conductor connection for the housing ground and should
not under any circumstances be replaced by other screws that
do not provide a proper grounding conductor connection.
General
The inverter is designed so that it does not require additional maintenance.
However, there are a few points to keep in mind during operation to ensure that the inverter functions optimally.

Warranty and Disposal
FRONIUS USA
limited 10Year Warranty
At Fronius, we have been designing and manufacturing high quality power
electronics equipment for over 60 years. And all our production facilities
are ISO 9001 certified.
You will probably not encounter any service-related issues with your Fronius CL solar inverter.
However, in the unlikely event that within Ten (10) years from the original
purchase you discover a problem caused by defects in either workmanship or materials, we will see that the device is either repaired or replaced.
Repair or replacement depends on Fronius’ evaluation of the issue and
what we decide makes the most sense according to the situation.
The warranty is based on the inverter’s serial number, allowing the warranty to be transferred to another owner if the Fronius CL solar inverter
remains installed in the original installation location. Because the warranty
is tied to the serial number, there is no paperwork to transfer the warranty
to a new owner.
Fronius CL solar inverters are designed to withstand normal operating
conditions and typical wear and tear when the Fronius CL solar inverter is
used for its original intent, in compliance with the Fronius CL Installation
and Operational Manual(s) supplied with the original equipment.
This warranty does not cover damages by improper installation or operation, misuse, abuse, manipulation, alterations or repair attempts, accidents,
fire, floods, acts of God, and incidental or consequential damage caused
by defects with other components of the solar system. This warranty does
not extend beyond the original cost of the Fronius CL solar inverter.
Policy and
Procedure for
Warranty
Returns and
Repairs
To obtain service you must follow this policy and procedure for warranty
returns and repairs:
- All returned Fronius CL solar inverters require a Returned Merchandise Authorization Number (RMA).
- A request for an RMA number requires the following information:
- Proof of purchase in the form of the original invoice
- Model number of the Fronius CL solar inverter
- Serial number of the Fronius CL solar inverter
- Description of the problem
- Shipping address for the repaired or replaced equipment
- All Fronius CL solar inverters authorized for return by FRONIUS USA
must be returned in their original shipping container or packaging
providing equal protection.
