The Deye SUN-15K-SG05LP3-EU-SM2 is the middle one of the three models we compare (12, 15 and 16 kW): 15 kW rated AC power (up to 16,500 VA), 22,500 W PV input power and a 48 V battery connection up to 280 A. Against the 12 kW model it has a higher battery current (280 against 240 A), two strings on one of its MPPT inputs (2 + 1) and an MPPT range from 160 V; against the 16 kW model it has 1 kW less power, 22,500 against 24,000 W of PV input and a 20 A lower battery current. Choose it when 12 kW is no longer enough but you do not need 16 kW. It runs on-grid, off-grid and as backup, IP65.

How the SUN-15K-SG05LP3-EU-SM2 differs from the 12 and 16 kW models
| Parameter | SUN-12K | SUN-15K (this model) | SUN-16K |
|---|---|---|---|
| Rated AC power | 12 kW | 15 kW | 16 kW |

Choose the SUN-15K when 12 kW is no longer enough (PV input up to 22,500 W, battery current up to 280 A) but you do not need 16 kW. If a smaller and lighter unit (35.2 kg) is enough, look at the SUN-12K-SG05LP3-EU-SM2. If you plan a larger PV array (24,000 W) or a stronger battery (300 A), take the SUN-16K-SG05LP3-EU-SM2; the 15 and 16 kW models are the same size (50.6 kg) and have the same MPPT range.
What is a 15 kW three-phase hybrid inverter used for?
The 15 kW model suits a three-phase home or commercial site on a 230/400 V supply (3L+N+PE) that needs up to 22,500 W of PV input power and a battery current of up to 280 A.
- When 12 kW is too little: rated power 15 kW, up to 16,500 VA, continuous AC passthrough from the grid to the load 70 A (45 A on the 12 kW model).
- Systems that need on-grid, off-grid and backup operation on one inverter.
- Upgrading an existing solar system: the inverter connects by AC coupling.
- When there are more panel strings: one of the two MPPT inputs can take two strings (2 + 1).
Hybrid inverter with battery: which batteries can I connect?
The SUN-15K-SG05LP3-EU-SM2 connects to 48 V low-voltage batteries in the 40–60 V range; lead-acid and lithium-ion batteries are supported. Maximum charge and discharge current is 280 A, there is 1 battery input, and several batteries can be connected in parallel.
With lithium-ion batteries the inverter adapts itself to the battery management system (BMS). Communication interfaces are RS485, RS232 and CAN. The manufacturer’s datasheet does not name specific battery models, so we confirm compatibility with you before you order.
How many solar panels can you connect to a 15 kW inverter?
The maximum PV input power is 22,500 W. The inverter has two MPPT inputs (2 + 1 strings), an MPPT voltage range of 160–650 V, a rated PV voltage of 550 V, a start-up voltage of 160 V and a maximum PV voltage of 800 V.
Maximum operating PV current is 36 + 20 A and short-circuit current is 54 + 30 A. The exact number of panels depends on string voltage and current, so we work out the strings from your panel data.
Can a hybrid inverter run off-grid or with a diesel generator?
In off-grid mode the SUN-15K-SG05LP3-EU-SM2 can deliver 2 × rated power for 10 s, i.e. 2 × 15 kW. Unbalanced output is 100 % on each phase, with maximum output up to 50 % of rated power. Maximum continuous AC passthrough from the grid to the load is 70 A.
Up to 10 inverters can be connected in parallel, both on-grid and off-grid. Storing energy from a diesel generator is also supported.
Grid connection and installation
The inverter has IP65 protection, weighs 50.6 kg and measures 456 × 750 × 268.5 mm (excluding connectors and brackets). Operating temperature is −40…+60 °C with derating above 45 °C; maximum altitude is 3000 m and noise is below 60 dB.
ESO (Lithuanian grid operator) states:
“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”
On the same page ESO adds that a storage system lets you reduce the power fed into the distribution grid, so in some cases a larger power plant can be connected than the grid limits alone would allow.
