Deye SUN-12K-SG02LP1-AM3

It is the most powerful model of the single-phase SG02LP1 family and is aimed at buildings that consume a lot on a single phase - large houses, guesthouses, small businesses. Like any hybrid inverter, it converts the current from the panels into the 230 V current in the sockets, charges the battery with the surplus and continues to supply the building when the grid is interrupted. It has three separate trackers for the panels, so the roof can be divided into three zones with different orientations.

With 12000 W of continuous power it simultaneously supports a professional kitchen, air conditioning, pumps and a boiler, and during a grid outage it delivers double this power for 10 seconds, enough to start the motors. Modules totalling up to 24000 W can be connected, of which a maximum of 19200 W is processed - a wide margin, designed for good production in the cold months as well. The battery charges and discharges at up to 250 A, that is roughly about 12 kW at 48 V, so practically the inverter can work at almost maximum power from the battery alone; the six programmable time intervals allow charging at cheap hours and discharging at expensive hours. The direct grid-load pass-through withstands 60 A. The device weighs 35,6 kg, measures 420x670x233 mm, has an enclosure sealed against dust and splashes, controlled ventilation below 45 dB and works between -40 and 60 °C.

PV: 24000 W of connected power, 19200 W maximum at the input, 3 MPPT with two strings each (2+2+2), 26+26+26 A (Isc 44+44+44 A), Vmax 500 V, start-up 125 V, MPPT window 150-425 V, rated 370 V. AC: 12000 W active, 13200 VA apparent, 54,6/52,2 A rated and maximum current, 220/230 V (0,85-1,1 Un), 50/45-55 Hz or 60/55-65 Hz, L+N+PE, bypass 60 A, off-grid 2x Pn for 10 s, maximum efficiency 97,6%, European 96,5%, MPPT efficiency above 99%. Low-voltage lead-acid or lithium battery, 40-60 V, 250 A charging/discharging, automatic adaptation to the BMS, 6 programmable time intervals. RS485/RS232/CAN communication, optional WiFi/Bluetooth/4G/LAN monitoring. IP65 enclosure, 420x670x233 mm, 35,6 kg, intelligent air cooling below 45 dB, operation -40...60 °C. Certifications: VDE-AR-N 4105, EN 50549-1, CEI 0-21, G98/G99, C10-11, UNE 217002, IEC 61727/62116.

Who it suits

Suitable for a large house, a guesthouse or a small business with a single-phase connection and high consumption, with a generous roof (up to 24 kW of panels connected) and with a battery bank sized for high currents.

Terms explained

• Maximum apparent power (VA): The total power required by the installation, including the part used by motors and transformers; that is why the device has 12000 W active and 13200 VA apparent.
• Discharge current of 250 A: It shows how quickly the battery can be emptied; at 48 V it means roughly about 12 kW, that is the battery can support almost the entire power of the inverter.
• Off-grid operation: The mode in which the building runs only on panels and battery, without the grid, either during a power cut or because there is no connection.

Technical specifications

Recommended applications

• Large homes and guesthouses with high single-phase consumption
• Small businesses with self-consumption and 48 V battery storage
• High-power backup for the whole building
• Hybrid systems with a diesel generator and AC coupling

Warranty

5 years, extendable to 10 years depending on the final installation location (Deye warranty policy)

Technical details

Specifications confirmed from the manufacturer's datasheet

Deye SUN-12K-SG02LP1-AM3 (SUN-12K-SG02LP1-EU-AM3) is the top variant of the single-phase SG02LP1 series, with 12 kW of rated power and three MPPT trackers. It accepts 24000 W of connected photovoltaic power and 19200 W of maximum PV input power, on 3 MPPT with two strings each (3/2+2+2), with 26+26+26 A of maximum working current and 44+44+44 A of short-circuit current. The maximum PV voltage is 500 V, start-up from 125 V, the MPPT range 150-425 V, rated PV voltage 370 V.

On the AC side it delivers 12000 W active rated and 13200 VA of maximum apparent power, with 54,6/52,2 A rated and maximum current, at 220/230 V (0,85-1,1 Un), 50/45-55 Hz or 60/55-65 Hz, L+N+PE connection. The grid-load bypass withstands 60 A, and in off-grid mode it delivers double the rated power for 10 s. Maximum efficiency 97,6%, European 96,5%, MPPT efficiency above 99%.

The low-voltage battery (lead-acid or lithium) works in 40-60 V, with 250 A maximum charging and discharging current, self-adaptation to the BMS and 6 programmable time intervals for charging/discharging. RS485/RS232/CAN communication, optional WiFi/Bluetooth/4G/LAN monitoring. The IP65 enclosure of 420x670x233 mm weighs 35,6 kg, with intelligent air cooling below 45 dB and operation between -40 and 60 degrees C. Certifications: VDE-AR-N 4105, EN 50549-1, CEI 0-21, G98/G99, C10-11, UNE 217002, IEC 61727/62116.
