Particularly noteworthy is a Corab Encor three-phase inverter with power outputs from 4 kW to 12 kW, and a maximum efficiency of up to 98.30%. It has a starting voltage of as low as 150 V, a maximum DC current of 16 A, and an exceptionally wide MPPT voltage range.
Moreover, it provides an apparent power at the AC output of up to 110% of the nominal power, and can be oversized by up to 200%. The operational safety of the Encor three-phase inverter is ensured by a built-in DC surge arrester.
The Encor inverter also features an IP66 protection rating, which guarantees safe outdoor installation. In addition, this inverter offers a wide operating temperature range from -30°C to +60°C.
For higher-power PV installations, Corab’s product range now includes a 50 kW inverter with a maximum efficiency of up to 98.4%, and an MPPT DC voltage range of 180~1000 V. It guarantees an option of oversizing by up to 150%.
Significantly, it has a lower weight compared to competing product, i.e. 44.5 kg, and offers an operating temperature range from -30°C to +60°C. Moreover, this Corab Encor inverter model features a built-in DC surge arrester, enables control of the energy discharge to the grid, and is cooled using longer-life fans. Just as importantly, this model features an IP66 protection rating, which means that it can be installed outdoors.
Corab also offers a three-phase hybrid inverter which can successfully combine a photovoltaic installation, an energy storage unit, and household equipment. It is characterised by asymmetric operation of up to 50% of the nominal output power per phase, and features an option of oversizing by up to 150%.
Importantly, a three-phase hybrid inverter guarantees the connectivity of high-power modules thanks to a maximum input DC current of 16A. Moreover, it offers parallel operation of up to 150 kW, as many as five different operating modes, and is also equipped with a built-in DC surge arrester.
The operation of the inverter can be monitored via the dedicated Corab ONE monitoring application. It is a proprietary installation monitoring system to check key parameters such as energy production, consumption levels, and the amount of energy released to and taken from the grid.
