What is a 30 kW three-phase grid-tied inverter for solar panels used for?
The Deye SUN-30K-G04 suits sites that use electricity while the solar PV system is producing:
- production halls
- offices and shops
- farms with refrigeration or pumps
Generation and consumption overlap in time, so a battery adds little here. This is a grid-tied inverter, so in the evening power is drawn from the grid again.
How many MPPTs does the SUN-30K-G04 have and how do you connect the panels?
The SUN-30K-G04 has 2 MPPTs, and each takes 3 strings. Two MPPTs help when panels face different directions or are shaded unevenly, because each group tracks its own maximum power point.
- Max. DC input power is 39 kW, max. voltage 1000 V and start-up voltage 250 V.
- MPPT voltage range is 200–850 V.
- Max. current per MPPT is 40 A, short-circuit current 60 A.
- DC connectors are MC4.
Can you connect a battery to a string inverter?
No, a battery cannot be connected to the SUN-30K-G04 grid-tied inverter. A battery 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 most of your electricity is used in the evening, it is worth comparing with a hybrid inverter. If you plan to add storage later, it is better to allow for it from the start.
Grid connection and monitoring
The inverter connects to a three-phase 3L/N/PE grid at 380 V or 400 V. Rated AC current is 43.5 A and max. AC current is 47.9 A. It has an integrated DC switch and complies with grid codes including VDE-AR-N 4105, IEC 62116, IEC 61727, G99, G98, NC RfG and EN 50549-1:2019.
Parameters can be monitored and changed remotely through the Deye monitoring platform, including shutdown and software updates. WiFi, GPRS, 4G and LAN modules, smart string monitoring and Anti-PID are available as options.
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.
