Operating modes
A. Energy management unit
This control can be used to switch the inverter on/off via an external (remote) control.
B. Network reactive power supply
The inverter is capable of producing reactive power and can therefore inject it into the grid by adjusting the phase shift factor. Injection management can be controlled directly by the grid operator via a dedicated RS485 serial interface.
C. Limiting the active power injected into the grid
If enabled, the inverter can limit the amount of active power injected into the grid by the inverter to the desired value (expressed as a percentage).
D. Auto-reduction of power when the grid is overfrequent
When the grid frequency is higher than the limited 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 remotely monitored using an advanced communication system based on the RS-485 serial interface, or remotely via WIFI/GPRS.
F. Software update
Support for local software updates via USB stick and remote updates via WIFI/GPRS.

What is the difference between the Sofar 2700TL-G3 and the 2200TL-G3, and which one to choose?
The 2700TL-G3 delivers 2,700 W — 23% more than the 2200TL-G3 (2,200 W). It accepts up to 3,700 Wp of panels (versus 3,000 Wp), its maximum output current is 13 A (versus 10.6 A), and its MPPT range is extended to 550 V (versus 500 V for all other models in the range). It is also slightly larger (321 × 260.5 × 131.5 mm versus 303 × 260.5 × 118 mm) and heavier (6.3 kg versus 5.5 kg). The annual production difference is approximately 400 to 600 kWh depending on your location. Choose the 2200TL-G3 for an installation of 8 panels on a single orientation; choose the 2700TL-G3 if you have 9 to 10 panels or high-voltage Voc modules (above 45 V) that require the extended MPPT range up to 550 V.
How many panels can be connected to the 2700TL-G3 and what is the logic of oversizing to 3,700 Wp?
The 2700TL-G3 accepts a maximum recommended PV power of 3,700 Wp — an oversizing ratio of approximately 137% relative to its nominal power of 2,700 W. This configuration typically corresponds to 8–9 panels of 415–460 Wp in series, or 7 panels of 530 Wp. The MPPT range extends from 50 to 550 V with a 70 V start voltage and a maximum input current of 12 A. This oversizing is economically justified as it allows more production during low-irradiance hours — morning, evening, and overcast days — without risk to the inverter, which simply clips output to 2,700 W when PV power exceeds its limit. Over a year, a ratio of 1.37 can increase production by 5 to 15% compared to a strict 1:1 ratio.
Why is the extended MPPT range up to 550 V of the 2700TL-G3 advantageous?
The 1100TL, 1600TL, and 2200TL models in the G3 range have an MPPT range limited to 500 V. The 2700TL-G3 is the only model in the range to offer an extended range up to 550 V. This advantage is concrete with modern large-format solar panels (550–670 Wp) whose open-circuit voltage (Voc) at low temperatures can exceed 45 V per panel. When stringing 10 panels of 550 Wp in series (Voc × 10 ≈ 480 V nominal, but potentially exceeding 500 V in cold weather depending on the temperature coefficient), the extended range to 550 V provides an essential safety margin to prevent the inverter from shutting down on cold winter mornings. This flexibility also allows longer strings to be wired with fewer parallel connections, reducing cabling costs.
Does the 2700TL-G3 exceed the Synergrid 5,000 VA limit for Belgium?
No. With a nominal power of 2,700 W, the 2700TL-G3 remains well below the 5,000 VA Synergrid limit for single-phase residential photovoltaic installations in Belgium (C10/11 standard). It is C10/11 certified, allowing it to be connected to the Fluvius, ORES, or Sibelga grid without any special administrative process. It is also certified VDE-AR-N 4105 (Germany), G83/2 (United Kingdom), and RD 1699 (Spain). However, if your total installation exceeds 5,000 VA (by combining this 2700TL-G3 with other inverters, for example), the rules applicable with your grid operator should be verified.
What are the implications of the 13 A maximum output current on AC wiring?
With a maximum output current of 13 A — versus 10.6 A for the 2200TL-G3 and 7.7 A for the 1600TL-G3 — the 2700TL-G3 requires particular attention to AC wiring sizing on the grid side. In practice, an AC cable with a minimum cross-section of 2.5 mm² (protected by a 16 A type C circuit breaker) is appropriate for connection to the distribution board. The nominal power of 2,700 W at 230 V corresponds to a nominal current of approximately 11.7 A, with a peak of 13 A. Sizing verification by a qualified electrician is recommended, particularly if the distribution board is old or if the cable run is long (voltage drop > 1%). These considerations are identical to the requirements of a standard domestic circuit for 3 kW resistive heating appliances.
Why is the 2700TL-G3 particularly suited to the standard family home in France or Belgium?
A standard European family home consumes on average 3,500 to 5,000 kWh per year. An installation of 9 panels of 400 Wp (3,600 Wp) combined with the 2700TL-G3 produces approximately 3,200 to 4,500 kWh per year depending on location (Belgium: 3,200–3,800 kWh; southern France: 4,000–4,500 kWh). With a self-consumption rate of 25 to 35% (proportion of produced energy consumed directly), this represents 800 to 1,500 kWh self-consumed per year — a saving of €200 to €375 annually at the residential rate of €0.25/kWh. The balance is injected into the grid. The 2700TL-G3 thus offers the best power/roof-space match to cover a third to half of a standard household's electricity bill, with a modest investment compared to hybrid systems with batteries.
Can multiple 2700TL-G3 units be used on the same residential installation?
Yes, technically several 2700TL-G3 units can be installed on the same single-phase residential connection, for example on different roof sections with distinct orientations. Each inverter independently manages its own string of panels, allowing each orientation to be optimised separately. However, the total cumulative injected power must not exceed the limit authorised by the grid operator (5,000 VA single-phase in Belgium under C10/11). Two 2700TL-G3 units connected in parallel on the same distribution board would exceed this limit (5,400 W), requiring a specific authorisation or activation of the zero export function to cap total injection. For installations exceeding 5 kW, a three-phase inverter (such as the Sofar ESI-5K-T1 or HYD-6KTL) or a hybrid inverter with self-consumption management is often more appropriate.
