Deye SUN-8K-SG05LP1-EU-AM2

This is a hybrid inverter for homes with high consumption, supplied on a single phase. Its role is to convert the current from the panels into the 230 V current of the sockets, to charge the battery with the surplus and to take over the supply of the house when the grid is interrupted. Compared with the smaller models, it has more panel inputs and a much higher battery current, so it can support powerful loads in the evening and at night.

The 8000 W continuous power covers a house in which the kitchen, the washing machines, the air conditioning units and an electric water heater run at the same time, and in the absence of the grid it can deliver twice this power for 10 seconds, enough to start the motors. Modules totalling up to 16000 W can be connected (of which a maximum of 12800 W is processed), distributed over two trackers with two strings each - enough for roofs with several orientations. The battery charges and discharges with up to 190 A, that is roughly about 9,1 kW at 48 V: in practice, the battery can also cover large loads, not just lighting and the fridge. The direct passthrough from the grid to the loads withstands 50 A. The maximum efficiency is 97,6%, the device weighs 24,9 kg at 330x580x232 mm and is cooled in a controlled way with air. It can be monitored from the phone through an optional WiFi, Bluetooth, 4G or LAN module.

IP65 enclosure, 330x580x232 mm, 24,9 kg, intelligent air cooling. Certifications: VDE-AR-N 4105, EN 50549, CEI 0-21, G98/G99, UNE 217002, IEC 61727/62116, IEC/EN 62109-1/-2.

Who it suits

Suitable for a large home on a single-phase connection, with many loads running at the same time and with a generous photovoltaic array (up to 16 kW connected), which wants real autonomy during a power cut, not just emergency circuits.

Terms explained

• Strings (panel strings): Groups of panels connected in series; two trackers with two strings each allow the panels to be divided into four groups, useful when the roof has several orientations.
• Battery charging/discharging current: How fast the battery can be filled or emptied; 190 A at 48 V means roughly about 9,1 kW, that is the battery can also supply large loads.
• Automatic adaptation to the BMS: The inverter reads over the data cable the information from the lithium battery and adjusts its charging regime by itself, without complicated manual settings.

Technical specifications

Recommended applications

• High-power backup for the whole home
• Hybrid systems with a diesel generator and AC coupling
• Extension in parallel up to 16 inverters

Warranty

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

Technical details

Series-level specifications — valid for the product family

Deye SUN-8K-SG05LP1-EU-AM2 is the 8 kW single-phase hybrid inverter of the SG05LP1-EU-AM2 generation, suitable for homes with high consumption and PV oversizing. According to the family datasheet, the 8 kW version supports 16000 W of connected photovoltaic power and 12800 W maximum PV input power, on 2 MPPT trackers with two strings each (2/2+2), with 32+32 A maximum working current and 48+48 A short-circuit current. The maximum PV voltage is 500 V, start-up from 125 V, the MPPT range 150-425 V, nominal PV voltage 370 V.

On the AC side it delivers 8000 W active rated and 8800 VA maximum apparent power, with 36,4/34,8 A rated current and 40/38,3 A 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-to-load bypass withstands 50 A, and in off-grid mode it delivers twice 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 190 A maximum charging and discharging current and self-adaptation to the BMS. RS485/RS232/CAN communication, optional WiFi/Bluetooth/4G/LAN monitoring. IP65 enclosure of 330x580x232 mm, 24,9 kg, intelligent air cooling. Certifications: VDE-AR-N 4105, EN 50549, CEI 0-21, G98/G99, UNE 217002, IEC 61727/62116, IEC/EN 62109-1/-2.
