Choose the SUN-40K-SG01HP3-EU when you need 40 kW of AC power or eight PV strings on four MPPT inputs. If 35 kW and six strings are enough, look at the SUN-35K-SG01HP3-EU. If 30 kW and one battery input are enough, look at the SUN-30K-SG02HP3-EU: it is lighter (46 kg) and has a 98.5 % max. efficiency.
Who is a 3 phase hybrid inverter with a high voltage battery for?
The SUN-40K-SG01HP3-EU suits a three-phase system that needs 40 kW of rated AC power, two battery inputs and a high-voltage (160–800 V) lithium battery.
- A solar PV system with a battery, when the PV side is split into eight strings on four MPPT inputs
- Sites that need the highest AC power of the three models (40 kW, 44,000 VA max.)
- Upgrading an existing solar system

How do you connect a hybrid inverter to the grid and a solar PV system?
The SUN-40K-SG01HP3-EU has a three-phase grid output of 230/400 V, 50/60 Hz, and the manufacturer states compliance with grid requirements including EN 50549 and VDE-AR-N 4105. ESO (Lithuanian grid operator) states:
“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”
ESO adds on the same page that a storage system makes it possible to reduce the power fed into the distribution grid, so in some cases a larger plant can be connected than the grid limits alone would allow.
