Sofar Solar Mono 1.1 kW Grid Inverter – 1100TL-G3

Sofar 1100TL-G3 solar inverter: Maximise your energy output

Compact single-phase inverters for small grid-connected PV systems

The SofarSolar 1.1K...3.3KTL-G3 is a sleek, compact and lightweight solar inverter for the smallest single-phase PV systems.

With an efficiency of up to 97.7%, it maximises the energy yield of your photovoltaic system. The built-in zero export function allows the user to limit the power fed into the grid by simply adding a current transformer to the system.

The inverter also comes with a WiFi dongle, allowing you to easily connect the inverter to the SofarSolar monitoring portal.

Operating modes

A. Energy management unit

This control can be used to switch the inverter on/off via an external (remote) control. 

B. Reactive power supply to the grid

The inverter is capable of generating reactive power and can therefore feed it into the grid by adjusting the phase angle. The feed-in management can be controlled directly by the grid operator via a dedicated RS485 serial interface. 

C. Limiting the active power fed into the grid

If enabled, the inverter can limit the amount of active power fed into the grid by the inverter to the desired value (expressed as a percentage). 

D. Automatic power reduction when the grid is over-frequency

When the grid frequency exceeds the limit value, the inverter reduces the output power, which is necessary for grid stability. 

E. Data transmission

The inverter or a group of inverters can be monitored remotely via an advanced communication system based on the RS-485 serial interface, or remotely via Wi-Fi/GPRS. 

F. Software updates

Support for local software updates via USB stick and remote updates via Wi-Fi/GPRS.
