WARNING! Incorrect operation or poorly executed work can cause serious injury or damage. Commis-
sioning of the hybrid system may only be carried out by trained personnel in accordance with the tech-
nical regulations. Before installation and commissioning, read the Installation Instructions and
Operating Instructions for the Fronius Symo Hybrid and the battery.
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC voltage from solar mo-
dules that are exposed to light.
- Ensure that both the AC side and the DC side of the inverter are de-energised before carrying out
any connection work.
- Only an authorised electrical engineer is permitted to connect this equipment to the public grid.
WARNING! An electric shock can be fatal. Danger due to grid voltage and DC voltage from solar mo-
dules or battery.
- The DC main switch is only to be used to de-energise the power stage set. The connection area
is still live when the DC main switch is switched off.
- Ensure that the power stage set and connection area are disconnected from one another before
carrying out any maintenance or service tasks.
- The power stage set is only to be disconnected from the mounting bracket once it is de-energised.
- Maintenance and servicing in the power stage set of the inverter must only be carried out by Fro-
nius-trained service technicians.
- Check that the battery is de-energised.
WARNING! An electric shock can be fatal. Danger due to residual voltage in capacitors. Wait for the
capacitors to discharge. The discharge time is five minutes.
WARNING! An inadequate ground conductor connection can cause serious injury or damage. The
housing screws provide a suitable ground conductor connection for grounding the housing and must
NOT be replaced by any other screws that do not provide a reliable ground conductor connection.
CAUTION! Risk of damage to the inverter from dirt or water on the terminals and contacts of the con-
nection area.
- When drilling, ensure that terminals and contacts in the connection area do not become dirty or
wet.
- Without a power stage set, the mounting bracket does not conform to the protection class of the
inverter as a whole and so must not be installed without the power stage set.
The mounting bracket should be protected from dirt and moisture during installation.
CAUTION! Risk of damage to the inverter as the result of incorrectly tightened terminals. Incorrectly
tightened terminals can cause heat damage to the inverter that may result in a fire. When connecting
AC and DC cables, ensure that all the terminals are tightened to the specified torque.
CAUTION! Risk of damage to inverter from overload.
- The maximum amperage when connecting to a single DC terminal is 32 A.
- Connect the DC+ and DC- cables to the DC+ and DC- terminals on the inverter, taking care to en-
sure that the polarity is correct.
- The maximum DC input voltage must not exceed 1000 V DC.
NOTE! Degree of protection IP 65 is only applicable if
- the inverter is placed in the mounting bracket and permanently attached using screws?
- the cover for the data communication area is permanently attached to the inverter with screws.
Degree of protection IP 20 applies to the mounting bracket with no inverter and the venting duct.
NOTE! The solar modules connected to the inverter must comply with the IEC 61730 Class A stan-
dard.
NOTE! When photovoltaic modules are exposed to light they supply current to the inverter.
