The Deye SUN-12K-SG05LP3-EU-SM2 is the smallest and lightest of the three SG05LP3-EU-SM2 inverters we compare (12, 15 and 16 kW): 12 kW rated AC power (up to 13,200 VA), 18,000 W PV input power, a 48 V battery connection up to 240 A and a weight of 35.2 kg. It is the top of the 3–12 kW range, so choose it for a home or small site where 12 kW is enough. If you need a battery current of 280–300 A or more PV input power, look at the 15 and 16 kW models. It works with the grid and off-grid, IP65.

How the SUN-12K-SG05LP3-EU-SM2 differs from the 15 and 16 kW models
| Parameter | SUN-12K (this model) | SUN-15K | SUN-16K |
|---|---|---|---|
| Rated AC power | 12 kW | 15 kW | 16 kW |
| Max. PV input power | 18,000 W | 22,500 W | 24,000 W |
| MPPT voltage range | 200–650 V | 160–650 V | 160–650 V |
| Max. operating PV input current | 20 + 20 A | 36 + 20 A | 36 + 20 A |
| Max. battery charge / discharge current | 240 / 240 A | 280 / 280 A | 300 / 300 A |
| Weight | 35.2 kg | 50.6 kg | 50.6 kg |
Choose the SUN-12K if 12 kW of AC power, up to 18,000 W of PV input and a battery current of up to 240 A are enough, and you want the lighter unit (35.2 kg against 50.6 kg). If you need more PV power or a stronger battery connection, take the SUN-15K-SG05LP3-EU-SM2 (22,500 W, 280 A) or the SUN-16K-SG05LP3-EU-SM2 (24,000 W, 300 A). On the 15 and 16 kW models the MPPT range starts at 160 V and one of the MPPT inputs can take two strings (2 + 1), while the 12 kW model has one string per input (1 + 1).
3 phase hybrid inverter 12 kW: who is it for?
The 12 kW model suits a three-phase home or small commercial site on a 230/400 V supply (3L+N+PE) where the PV array input does not exceed 18,000 W and the battery connects to a single 48 V (40–60 V) input at up to 240 A.
- A new solar PV system with a battery: two MPPT inputs with one string each, 200–650 V.
- Upgrading an existing solar system: the inverter connects by AC coupling.
- Sites where a diesel generator may be needed: energy storage from a generator is supported.
- Where space matters: 386 × 660 × 250 mm and 35.2 kg, lighter than the 15 and 16 kW models (50.6 kg).
Hybrid inverter with battery: batteries and connection
The SUN-12K-SG05LP3-EU-SM2 connects to 48 V low-voltage batteries with a voltage range of 40–60 V; lead-acid and lithium-ion batteries are supported. The maximum charge and discharge current is 240 A, the inverter has 1 battery input, and several batteries can be connected in parallel.
With lithium-ion batteries the inverter adapts to the battery management system (BMS) by itself. Its communication interfaces are RS485, RS232 and CAN. 6 battery charge and discharge periods can be set. The manufacturer’s datasheet does not name specific battery models, so we check compatibility before you order.
How many solar panels can you connect to a 12 kW inverter?
The maximum PV input power is 18,000 W, and the maximum PV access power is 24,000 W. These are two different values.
The inverter has two MPPT inputs with one string each. The MPPT voltage range is 200–650 V, rated PV voltage is 550 V, start-up voltage is 160 V and maximum PV voltage is 800 V. Maximum operating PV current is 20 + 20 A and short-circuit current is 30 + 30 A. The exact number of panels is set by these limits, so we work out the strings from the data of your panels.
Off-grid operation and diesel generator
In off-grid mode the SUN-12K-SG05LP3-EU-SM2 can deliver 2 × rated power for 10 s, i.e. 2 × 12 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 45 A (70 A on the 15 and 16 kW models).
Up to 10 inverters can be connected in parallel, both on-grid and off-grid. Energy storage from a diesel generator is also supported.
Grid connection and installation
The inverter has IP65 protection, a weight of 35.2 kg and dimensions of 386 × 660 × 250 mm (without connectors and brackets). Operating temperature is -40 to +60 °C with power derating above 45 °C; permissible altitude is 3000 m and noise is 55 dB.
On storing solar energy in a battery, 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 lets you reduce the power you generate into the distribution grid.
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.
