1.0: Overview
1.1 Inverter for Grid-Tied PV Systems
The PVI 50/60TL inverter is suitable for use on commercial and utility-scale rooftop,
carport and ground mount grid-tied PV systems. A system is generally made up of PV
modules, DC power distribution equipment, PV inverter and AC power distribution
equipment (Figure 1.1). The inverter converts DC from PV modules to AC with the
same frequency and phase as the AC grid. All or part of the AC power is supplied to
local loads, and the surplus power is supplied to the electricity grid.

1.3 Product Protection Functions
Reverse polarity protection on the DC inputs
Short circuit protection
Arc-Fault Circuit Interruption
Anti-islanding protection
Input and output over-voltage protection
Input over-current protection
Monitoring of:
DC input insulation against ground

1.4 Circuit Structure Design
The basic schematic diagram of PVI 50/60TL inverter is shown in Figure 1.2. The input
of PV modules passes through surge protection circuitry, DC EMI wave filter, and the
front-end boost circuitry to achieve maximum power tracking and boost up voltages.
The output of the inverter converts the DC voltage to 3-phase AC voltage. The high
frequency AC components are removed with a wave filter. The 3-phase AC voltage is
then passed through two-stage relays and EMI wave filter to produce high quality AC
power.

1.6 Anti-Islanding
This inverter includes active Anti-Islanding detection as required by
UL1741/IEEE1547. The inverter will automatically make small variations in reactive
power output in order to detect a possible islanding condition. If the grid is stable,

PVI 50/60 TL Installation and Operation Manual (Rev C)
DOCR-070645-E Page 13 of 102
these small variations will have negligible effects on system voltage and frequency.
However, in an islanded condition the small amount of reactive power changes will
force the system voltage or frequency to change significantly, which will trigger the
inverter to shut down. This function is always on and cannot be turned off by the
user.
1.7 DC Ground Fault Protection
The PVI 50/60TL includes residual current detection as part of the DC ground fault
detection method as required by UL1741. If there is a ground fault in the array, the
ground fault detection technology will detect the array leakage current. The
inverter will shut down if the leakage current exceeds 500mA.
1.8 Surge Suppression
Standard 1.2/50 μs - 8/20 μs Combination Wave
Standard 0.5 μs - 100 kHz Ring Wave
1.9 DC Arc Fault Detection
The PVI 50-60TL includes DC arc fault detection compliant with UL 1699B. The
inverter detects electrical noise that typically accompanies a DC series arc. The
inverter will shut down should the arc fault sensor detect a series arc.

2.1 Recommendations Before Installation
Check that the product environmental specifications (protection degree,
operating temperature range, humidity and altitude, etc.) meet the
requirements of the specific project location.
Make sure that the AC grid voltage is within the normal range.
Ensure that the local electricity supply authority has granted permission to
connect to the grid.
Installation personnel must be qualified electricians or have received
professional training.
Sufficient space according to Figure 2.3 should be provided to allow the
inverter cooling system to operate normally.
Install the inverter away from flammable and explosive substances.
Avoid installing the inverter in locations that exceed the temperature limits
specified in the inverter data sheet to limit undesirable power loss.
Do not install the inverter near an electromagnetic source which can
compromise the normal operation of electronic equipment.
