Deye SUN-8K-SG05LP1-EU single-phase hybrid inverter

The Deye SUN-8K-SG05LP1-EU: 8 kW for large residential installations

The Deye SUN-8K-SG05LP1-EU is the 8,000 W / 48V single-phase hybrid inverter from the SG05LP1 range, the most powerful in Deye’s single-phase series. It is designed for homes of 150 to 300 m², properties with a swimming pool or heat pump, and small businesses wishing to maximise their solar self-consumption with storage. With 16 kWp of connectable panels, a battery charging current of 190A and an off-grid peak power of 16 kW for 10 seconds, it is the most comprehensive inverter in the range for an ambitious installation.

What this inverter actually does

• It converts the energy from your solar panels into 230V AC electricity with a maximum efficiency of 97.6% and a European efficiency rating of 96.5%
• It stores surplus energy in a 48V lithium or lead-acid battery for use in the evening, at night or during a grid outage
• It automatically switches to the battery in the event of a grid outage, with a peak power of 16 kW for 10 seconds to start up all your appliances without delay
• It feeds surplus energy back into the grid if your contract allows

With 20 to 30 solar panels (10 to 16 kWp) and a 10 to 30 kWh battery, a large house can achieve 70 to 85% self-consumption, representing an estimated saving of between €1,200 and €2,000 per year depending on your consumption profile.

16 kWp of connectable PV: up to 30 panels across 2 MPPT

The SUN-8K-SG05LP1-EU features 2 independent MPPT trackers with 4 physical inputs (strings) — 2 strings per MPPT — allowing for the management of up to 4 different roof orientations:

• MPPT voltage range: 150 to 425 V, max. voltage 500 V
• Up to 16,000 Wp of connectable panels
• Typical configuration: 4 strings of 4 to 8 x 400–500 Wp panels
• Ideal for large L-shaped roofs, multiple roofs or installations combining south/east/west orientations

190A charging current: the battery charges as quickly as possible

With a maximum charge and discharge current of 190A, the SUN-8K-SG05LP1-EU is capable of charging a 48V 9.6 kWh battery in under an hour when solar production is high. This is one of the highest charge currents in its class, ensuring:

• A fully charged battery before nightfall, even in summer when there are few hours of optimal sunshine
• Fast charging from the grid during off-peak hours if you have a dual-rate tariff
• Rapid discharge to cover consumption peaks (heat pump, water heater, EV charger)

Main screen

The touchscreen LCD display provides all essential information about the inverter in real time.

1 • Central icon indicating normal operation or any errors.

2 • Display of the time and system status.

3 • Access to settings: system configuration, battery, grid and generator.

4 • Information on solar power, the grid, the battery and energy flows, with a clear display of power levels.

Remote shutdown function

The smart monitoring platform enables immediate remote shutdown, firmware updates and simplified maintenance for your solar installation.

Compatible battery: all 48V lithium or lead-acid batteries

The SUN-8K-SG05LP1-EU is one of the most open hybrid inverters on the market in terms of battery compatibility:

The lithium charging strategy is self-adaptive to the BMS: the inverter automatically reads the battery parameters and adjusts the charge without manual configuration.
