General information in this chapter Product dimensions
The field of use and overall dimensions of the 1.1K-3K TL inverters are indicated in this section.
Function description
It describes how the 1.1K-3K TL inverters and their internal operating modules work.
Efficiency curve
It describes the efficiency curves of the inverter.
2.1. Product presentation
Field of use
The 1.1K-3K TL inverters are grid-connected photovoltaic inverters equipped with a single MPPT channel, capable of converting the direct current generated by the photovoltaic strings into single-phase sine wave alternating current and feeding the energy to the public electricity grid. An AC circuit breaker (see chapter 4.4) and DC circuit breaker must be used as disconnecting devices and must always be easily accessible.

Figure 2 – Grid-connected photovoltaic system
The 1.1K-3K TL inverters can only be used with photovoltaic modules that do not require one of the poles to be grounded. The input current and voltage of the PV strings must not exceed the limits specified in the technical specifications. Only photovoltaic modules can be connected to the input of the inverter (do not connect batteries or other power supply sources).
• Accessories and optional components of the inverter should be chosen by a qualified technician who is
familiar with the installation conditions.
• Overall dimensions: L x W x H = 405.5 mm x 314 mm x 135.5 mm

2.2. Description of functions
The DC power generated by the PV modules is filtered through the input board before entering the power board. The input board also has the function of detecting the insulation impedance and the DC input voltage/current. The power board converts the DC power into AC power. The current converted into AC is filtered through the output board and is then fed into the grid. The output board also has the function of measuring the grid and GFCI voltage/current, and acts as an output insulation relay. The control provides the auxiliary power supply, controls the operating status of the inverter and shows it on the display. The display also shows the error codes when the inverter is not functioning properly. At the same time, the control board can activate the protection relay in order to disconnect the inverter from the grid and protect the internal components.
Inverter functions
A. Feeding reactive power into the grid
The inverter is able to produce reactive power and feed it into the grid through the setting of the Power Factor. The feed-in management can be controlled directly by the grid company through a dedicated RS485 interface.
B. Limiting the active power fed into the grid
If enabled, the inverter can limit the amount of active power fed into the grid at the desired value (expressed as a percentage).
C. Automatic power reduction when grid is over frequency
When the grid frequency is higher than the limit set, the inverter reduces the output power in order to ensure the stability of the grid.
D. Data transmission
The inverter (or a group of inverters) can be monitored remotely via an advanced communication system based on a RS485 interface or via Wi-Fi.
E. Software update
A microSD card is used to update the firmware.
