Product description

The Sofar 255KTL-HV is an industrial-sized on-grid inverter specifically designed for large-scale solar power plants and industrial facilities. With a rated power of 255 kW and an efficiency of up to 99.02%, it ensures that the generated energy is fed into the grid to the maximum extent.

The inverter works with 12 MPP trackers, which allows flexible management of large and distributed solar arrays. The PID regeneration function and IV curve scanning help ensure long-term stable performance and quick identification of faults.

For safety, the device is equipped with type II overvoltage protection on both DC and AC sides, as well as ground fault, islanding and leakage current protection. The C5 corrosion protection coating and IP66 protection allow outdoor installation, even in extreme environments.

The device features compatible aluminum and copper AC cables, dual power supply (AC/DC redundancy), and 24-hour status monitoring. Communication is via RS485 and PBUS connections, and setup and monitoring are available via LCD display, Bluetooth, or mobile app.

255 kW three-phase power
12 MPP trackers for flexible planning
Efficiency: max. 99.02%
PID regeneration and IV curve study
DC and AC side surge protection (Type II)
IP66 and C5 outdoor protection
AC/DC redundant power supply, 24-hour monitoring
RS485 and PBUS communication, Bluetooth + APP access

The Sofar 255KTL-HV is therefore the perfect choice for any large system where reliability, efficiency and long-term operational safety are primary considerations.

How do I choose the right inverter?

When choosing an inverter, it is worth considering the power of the solar panels, their voltage range, the number of phases in the system (single- or three-phase), and whether you plan to expand with batteries in the future.

In the case of three-phase systems, a distinction must be made between symmetrical and asymmetrical inverters. The symmetrical type distributes the power equally across all three phases, which is an advantageous solution for simpler networks. The asymmetrical inverter, on the other hand, can regulate the power differently per phase, thus adapting more flexibly to the real consumption pattern of the house - for this reason it is usually the more practical and efficient choice for domestic systems.

When is it worth choosing a hybrid inverter?

It is worth choosing a hybrid inverter if you want to expand the system with battery energy storage in the future or if you want to provide the house with protection against power outages.

Hybrid models are more expensive, but offer a more flexible solution in the long term, as they can be easily integrated into the existing system later.

What happens in the event of a power outage?

During a power outage, traditional grid-fed inverters automatically shut down to prevent power from being fed back into the utility grid for safety reasons.

Hybrid inverters, on the other hand, can operate in stand-alone, so-called backup mode, if a battery is also connected to the system. In this case, the inverter disconnects itself from the grid and uses the energy stored in the battery to continue supplying designated consumers in the house, such as lighting, a refrigerator or a router. As soon as the grid voltage returns, the inverter automatically returns to normal operation and begins recharging the battery.

What warranty does the inverter have?

The warranty is typically 5-10 years, depending on the manufacturer and model. Some manufacturers also offer extended warranties with registration. The exact duration is listed on each product page, so it's worth checking before purchasing.

What happens if the inverter fails?

As a first step, it is always recommended to diagnose the fault, because often the problem is not related to the inverter, but to the settings or the communication module.
If there is an actual failure, the distributor or manufacturer's service partner will assist with the repair or replacement process, within or beyond warranty.
