What is a 100 kW grid-tie inverter for a solar PV system used for?
The Deye SUN-100K-G03 suits sites that use electricity during the day, while the solar PV system is producing:
- a production site
- an office or a shop
- a farm with refrigeration or pumps
Generation and consumption coincide in time here, so the benefit of storage is small. This is a grid-tie inverter, so in the evening electricity is drawn from the grid again.
How many MPPTs does the SUN-100K-G03 have and how are the panel strings connected?
The SUN-100K-G03 has 6 MPPTs with 4 strings per MPPT. Separate MPPTs let you connect panels facing different directions or partly shaded, because each MPPT tracks its own maximum power point.
- Maximum PV input voltage is 1000 V and start-up voltage is 250 V.
- The MPPT voltage range is 200–850 V and the rated PV input voltage is 600 V.
- Each MPPT has a maximum operating current of 40 A and a short-circuit current of 60 A.
- Maximum PV input power is 150 kW.
Can a battery be connected to a string inverter?
No, a battery cannot be connected to the grid-tie SUN-100K-G03. 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 most of your electricity is used in the evening, it is worth comparing with a hybrid inverter. If you plan storage in the future, it is better to allow for it from the start.
How is the SUN-100K-G03 connected to the grid and what should you know before buying?
The inverter connects to a three-phase 3L/N/PE grid with a rated output voltage of 230/400 V. At 400 V the rated AC current is 144.9 A and the maximum is 159.4 A. It is transformerless, has Type II surge protection on both the DC and AC sides, and meets grid codes including EN 50549, VDE-AR-N 4105, IEC 62116 and G99.
- It weighs 81 kg and measures 826 × 516 × 312.7 mm, so plan suitable lifting and fixing for installation.
- Noise is 55 dB(A), so choose the location with nearby rooms in mind.
- It operates from −25 to +65 °C, with derating above +45 °C.
- Manufacturer’s warranty is 5 years.
