What is the Deye SUN-50K-G03 inverter used for?
The Deye SUN-50K-G03 is designed for a three-phase PV system of up to 50 kW where most electricity is used during the day. The manufacturer does not name specific building types, so check the expected consumption of your site with us. Four MPPT trackers let you split the panels into several groups, and the inverter offers zero export and VSG functions.
How much solar power can you connect to a 50 kW inverter?
You can connect up to 65 kW of DC power to the Deye SUN-50K-G03, which is the maximum DC input power given by the manufacturer. The string voltage must fit within the 200-850 V MPPT range (maximum input voltage 1000 V, start-up voltage 250 V), with 3 strings for each of the 4 MPPTs.
Can you connect a battery to a grid-tie inverter?
No. The Deye SUN-50K-G03 is a grid-tie inverter, so a battery cannot be connected to it, and in the evening, when the sun is gone, power is drawn from the grid. Storage needs a hybrid inverter or a separate storage inverter. ESO (Lithuanian grid operator) states:
“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”
If electricity is needed mostly in the evening, a hybrid inverter is worth comparing. We are happy to assess both options against the consumption profile of your site.
Installation and connection
The Deye SUN-50K-G03 weighs 44.5 kg and measures 647.5 × 537 × 303.5 mm; noise is below 45 dB. The manufacturer specifies an IP65 enclosure, MC-4 compatible DC connectors and an IP65 AC plug, and output power is derated above +45 °C.
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.
