General Safety Instructions
1. General Safety Instructions
DANGER
Risk of death by electrocution
Potentially fatal voltage is applied to the solar inverter during operation. This
potentially fatal voltage is still present for ve minutes after all power sources
have been disconnected.
►Never open the solar inverter.
►Always disconnect the solar inverter from power before installation, open
the DC isolating switch and make sure neither can be accidentally recon-
nected.
► Wait at least ve minutes until the capacitors have discharged.
DANGER
Risk of death or serious injury from electrocution
Potentially fatal voltage may be applied to the DC connections of the solar
inverter.
►Never disconnect the PV modules when the solar inverter is powered.
►First switch off the grid connection so that the solar inverter cannot feed
energy into the grid.
►Then open the DC isolating switch.
►Make sure the DC connections cannot be accidentally touched.
●The solar inverter can be safely and normally operated if installed and used in accordance
with this manual (see IEC 62109-5.3.3). Delta Energy Systems is not responsible for damage
incurred by failure to observe the installation and operating instructions in this manual. For
this reason, be sure to observe and follow all instructions!
● Installation and commissioning may only be performed by qualied electricians using the
installation and commissioning instructions found in this manual.
●The solar inverter must be disconnected from power and the PV modules before any work on
it can be performed.
●The solar inverter has a high leakage current value. The ground wire must be connected
before commissioning.
●Do not remove any warning signs that the manufacturer has installed on the solar inverter.
● Improper handling of the solar inverter my result in physical injury and damage to property.
For this reason, observe and follow all general safety instructions and warnings.
●The solar inverter contains no components that must be maintained or repaired by the opera-
tor or installer. All repairs must be performed by Delta Energy Systems. Opening the cover
will void the warranty.
●Do not disconnect any cables when the solar inverter is powered due to risk of a fault arc.
●To prevent lightning strikes, follow the relevant regulations applicable in your country.
●The surface of the solar inverter can become very hot.

8
General Safety Instructions
●The solar inverter is very heavy. The solar inverter must be lifted and carried by at least two
people.
●Only devices in compliance with SELV (EN 69050) may be connected to the RS485 and USB
interfaces.
● All connections must be sufciently insulated in order to comply with the IP65 protection rat-
ing. Unused connections must be closed by placing cover caps on the solar inverter.

hazardous situation is not avoided
DANGER!
DANGER!
Death and serious injury will occur if this haz-
ardous situation is not avoided

2.3 Validity
This user manual describes the installation procedures, maintenance, technical data and safety
instruction of the specied solar inverter models under the DELTA brand.
The software version of your inverter is found on the inverter display. Please nd more information
in section 7.35 “Inverter Information.”
2.4 Product Description
The SOLIVIA TL inverters are 3 phase grid-tied solar inverters with reactive power control. These
devices convert direct current (DC) electricity from photovoltaic power collected from PV arrays
into 3 phase alternating current (AC) to feed the excess capacity back to the local mains electri-
cal grid. Using cutting-edge technology allows a wide voltage input range (250~1000 V) and high
performance efciency based on a user-friendly operation design. In addition, special DSP (Digital
Signal Processor) design decreases the circuit complication and electronic components. Please
note that this device does not support off-grid function. The following are the key features of
SOLIVIA TL series 3 phase grid-tied solar inverters.

10
General Information
Key Features
●Power Rating: 6 / 8 / 10 / 12 / 15 / 20 / 30 kVA
●Power Balancing (33/67) in asymmetrical dc loading situations
●3-Phase (3-Phase + N + PE), Grid-tie, Transformerless solar inverter
● Maximum efciency: up to 98.2 %
● Europe efciency: up to 97.8 %
●Reactive power capability (Cap 0.80 - Ind 0.80)
● Low input current harmonic distortion (THD < 3%) @ full load
●2 MPP Trackers
●Record up to 30 event logs.
●5” LCD display
●EPO
The SOLIVIA TL inverters comply with the latest country regulations and standards. Please see
the list on the website www.solar-inverter.com for the complete list of compliance standards.
2.5 Application & Intended Use
The operation of the solar inverter is as shown as in the gure 2.1. In order to save energy and
electricity, solar inverters convert the DC input power supplied from the PV array into three-phase
AC output power to the grid.
NOTE
Languages supported: English, Italian, French, German, Dutch, Spanish
The solar power inverter may only be used as intended.
Proper use of the solar power inverter meets the following criteria:
●Use in stationary PV systems connected to the local power grid for converting the direct cur-
rent in the PV system to alternating current and feeding it into the grid
● Use within the specied power range (see Sec. 12.1 - Technical Specications) and under
the specied ambient conditions (indoor area or covered outdoor area with up to IP65)
Any of the following uses of the solar power inverter is considered improper:
●Isolated operation: The solar power inverter has anti-islanding and other monitoring features.
●Use in mobile PV systems.

2.7 Monitoring
The SOLIVIA TL inverters include a display for monitoring performance on location. Remote
monitoring is also an option for the TL series inverters with Solar Log and Meteocontrol as well as
Delta’s own monitoring solution, SOLIVIA Monitor G2. Please contact your Delta supplier for more
information on these remote monitoring options.
SOLIVIA Monitor G2 ensures reliable operation and maximum performance of PV systems. The
system is compatible with all SOLIVIA String Inverter models from Delta. The all-in-one solution
is made up of the SOLIVIA GW M1 G2, a gateway that acts as an interface, and an online portal
that is available to users at http://monitoring.solar-inverter.com. Both real-time data reports and
historical data statistics can be generated and exported as a CSV or Excel le. Automated alert
messages notify the operator and ensure that the solar investment pays off. The installer also has
the opportunity to manage its customers’ systems in order to gain a quick overview of the system
status at all times. What’s more, the user receives information on the weather and also the latest
news via the integrated news feed.
