Intended purpose
The SOLIVIA 3.0 TL and 5.0 TL are single phase grid-tied
solar inverters. These device converts direct current (DC)
electricity from photovoltaic power collected from PV Array
into single phase alternating current (AC) to feed the excess
capacity back to the local mains electrical grid. The models
allow wide voltage input range (150~630Vdc - SOLIVIA
3.0 and 200~1000Vdc - SOLIVIA 5.0) and high perfor-
mance efficiency based on user friendly operation design.
In addition, special DSP (Digital Signal Processor) design
decreases the circuit complication and electronic compo-
nent. Please note that this device does not support off-grid
function.
Features for 3.0 TL and 5.0 TL
● Power Rating: 3 kVA - 3.0 TL; 5 kVA - 5.0 TL
● Integrated web server and WiFi for wireless
connectivity
ETHERNET WIRELESS
● Single Phase (L + N + PE), Grid-tie, Transformerless

General safety instructions
English
DANGER
Risk of death by electrocution
Potentially fatal voltage is applied to the so-
lar inverter during operation. This potentially
fatal voltage is still present for five minutes
after all power sources have been discon-
nected.
► Never open the solar inverter.
► Always disconnect the solar inverter
from power before installation, open the
DC isolating switch and make sure nei-
ther can be accidentally reconnected.
► Wait at least five minutes until the ca-
pacitors 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 en-
ergy 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 ob-
serve 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 qualified electricians using the installation and com-
missioning 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 commis-
sioning.
● 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 operator or installer. All
repairs must be performed by Delta Energy Systems.
Opening the cover will void the warranty.
