TL Inverter (1500-12500 W)

TL Inverter (1500-12500 W)

Solar Inverters (On-Grid Inverter)

Sirio EASY
Easy installation and use Lightness, compactness, ease of installation and configuration; these are the special characteristics of the EASY series which are particularly suited for residential and small scale commercial installations. In fact, thanks to the wide range of voltage and input current, they are found to be extremely well adapted to systems that have size limitations.

Main Features:

Cooling system
The cooling system used in the EASY series, comprising of a temperature controlled fan, efficiently conducts heat outside the casing, and is switched on only if strictly required. The operating temperature is controlled by specific sensors, which, in extreme cases, reduce the output power to protect the device from overheating, hence protecting the inverter from complete stoppage.

Sirio EVO
Reliability and versatility for all requirements The wide range of inputs, on account of the adoption of the NPC topology, together with IP65 degree of protection, allow it to be placed outside the inverter near the generator, simplifying the wiring on the DC side, reducing the loss and containing the installation costs. The multi-string technology also allows strings with different orientations and inclinations to be managed, so as to work better with multiple models and panel types, even if there is partial shading; making the inverter more flexible and assisting the installer in different configurations. The integrated DC switch disconnector allows the inverter to be rapidly and securely isolated in the event of an emergency or extraordinary maintenances.

Common Features
Quality power supplier TL inverters implement innovative technologies, have high quality components, are sized with a wide margin for normal operations and can provide for routine machine maintenance without compromising on the wide-ranging operational flexibility. The innovative digital control for all power stages guarantees low susceptibility for power disruptions, avoiding undesired disconnection due to variations or micro-interruptions. The Sirio EASY and EVO inverters integrate input and output surge protection and have control devices and redundancy protection- especially in the output stages- to guarantee operability and continuous operation.

Higher conversion efficiency
The Sirio EASY and EVO series inverters have been manufactured with galvanic separation, optimising the size and weight and thereby improving the ergonomics of the entire system. Thanks to the use of “transformerless” technology and state-of-the-art components, TL inverters guarantee conversion efficiencies of up to 98%.

Simple Communication
An LCD situated on the front panel displays all the main information in a simple and intuitive manner: power, energy produced and any faults, referring to other parameters such as grid voltage, the voltage of the photovoltaic modules and the grid frequency. The inverter also has an integrated data logger which records the instantaneous data with a configurable frequency between 5 and 60 minutes in addition to saving the production data every day for a period of about two years. With a simple setting, it is also possible to activate the night-time consultation function, which queries the inverter through a (series) USB, RS485/422 bus or other slot cards (optional) even during the night when the device is normally switched off.

Internal GFCI (Ground Fault Circuit Interrupter)
In accordance with article 712.413. of section 712 of the IEC 64-8/7 Norms, the TL inverters are designed in such a manner so as not to pass continuous earth fault current. In fact, the inverters have an advanced break-down protection circuit that continuously monitors the leakage current to the ground; this protection is in fact a Class B differential. In the case of an earthing fault, the converter is deactivated and the fault is indicated with a red LED and suitable error code on the front control panel.

Certified quality
For the first time in Italy, the EASY and EVO series inverters have obtained the IMQ certification, guaranteeing reliability and product quality to the consumer. This certification, which is attested by a third party, proves that the product conforms to the characteristics of performance and security set by the Italian and European technical standards.
