Growatt TL3-X Series User Manual

AC connection steps(just for Vietnam models):
1.Pass the 5 wires (A,B,C,N and PE wires) through the AC shield,connect them to the
power grid, and then crimp the O/U terminal.
2. Lock the AC cable to the corresponding AC terminal.
3.Lock the protective cover on the inverter frame, and finally tighten the protective cover
hole.

Ø Sunlight will generate voltage on the battery panel.The high voltage
after the series connection may cause life danger.Therefore, before
connecting the DC input cable,you need to cover the battery panel with an
opaque material before operation,and ensure the reverse The DC switch of
the inverter is in the "OFF" state,otherwise the high voltage of the inverter
may cause life danger.
Ø To avoid electric shock,do not touch the live parts,and connect the
terminals carefully.
Ø Please make sure that the AC switch has been disconnected before
wiring.
Please ensure that the following conditions are met, otherwise it may
cause a fire hazard or damage the inverter. In this case, the company
does not carry out quality assurance and assumes any responsibility.
Ø The maximum open circuit voltage of each string of photovoltaic
modules shall not exceed 1100Vdc under any conditions.
Ø PV modules connected in series in each PV string are of the same
specification type.
Ø The maximum short-circuit current of each PV string must not exceed
26A under any conditions.
Ø The total output power of all PV strings must not exceed the maximum
input power of the inverter.
Ø In order to optimize the system configuration,it is recommended to
connect the two inputs with the same number of photovoltaic modules.
Ø If the inverter output is directly connected to the grid (that is, the
o u t p u t s i d e i s n o t c o n n e c t e d t o a l o w - f r e q u e n c y i s o l a t i o n
transformer),please ensure that the PV string is not grounded.
If the inverter is a specific type of thin-film battery module (PV-
grounded),please connect the low-frequency isolation transformer to the
output terminal before turning it on,otherwise the inverter will be
damaged.
Ø If a stable non- zero DC voltage is measured between the positive
pole of the photovoltaic string and the ground,it means that an
insulation fault has occurred at a certain position in the photovoltaic
string.You need to ensure that the fault is repaired before continuing
the wiring.
