Deye SUN-10K-SG02LP1-EU – 10 kW single-phase hybrid inverter, 220A charging current

SG02LP1 vs SG05LP1: two ranges, two philosophies

The Deye SUN-10K-SG02LP1-EU belongs to the SG02LP1 range — a different architecture from the SG05LP1 range (SUN-8K, SUN-5K...) featured in the rest of the catalogue. The differences are significant:

220A charging current: the battery charges at top speed

The maximum charge and discharge current of 220A is this product’s most remarkable feature — and the highest in the entire wattuneed.com catalogue. On a 48V battery, this represents a charging power of 10,560 W, i.e. the inverter’s full rated power entirely dedicated to battery charging if necessary. In practical terms:

• A 48V 10 kWh battery charges in under an hour with abundant solar production
• Charging from the grid during off-peak hours is ultra-fast
• Discharge is powerful enough to cover all simultaneous consumption peaks in a large house

3 independent MPPT trackers, 6 strings: maximum flexibility

With 3 independent MPPT trackers, each comprising 2 strings (6 physical inputs in total, 25A each, range 150–425V, max 500V), the SUN-10K-SG02LP1-EU can manage up to 6 different strings completely independently:

• 3 different roof orientations (south, east, west or any combination) without cross-shading loss
• Up to 20,000 Wp of connectable panels — approximately 40 to 50 panels of 400–500 Wp
• Optimal management of partial shading thanks to independent MPPT
• Ideal for L-shaped roofs, houses with multiple exposed sides, or installations combining a main building and outbuildings

20 kW peak power in backup mode

In the event of a grid outage with a 48V battery connected, the SUN-10K-SG02LP1-EU delivers 20 kW for 10 seconds — twice its rated power. This is sufficient to simultaneously start up the most power-hungry equipment on a large property or in a small business.

Battery compatibility: all 48V lithium or lead-acid batteries

Like the entire Deye 48V range, the SUN-10K-SG02LP1-EU is compatible with almost all 48V batteries on the market:

BMS communication: RS485, RS232 and CAN — auto-adaptation to lithium BMS.

What this inverter actually does

• It converts solar energy into 230V AC electricity with a maximum efficiency of 97.6% (EU 96.5%, MPPT 99%)
• It stores surplus energy in the 48V battery at a current of 220A
• It switches to backup mode during a grid outage with a peak output of 20 kW for 10 seconds
• It feeds surplus energy back into the grid (France, Luxembourg)

With 30 to 40 panels (15 to 20 kWp) and a 10 to 30 kWh battery, a large house or small business can achieve 72 to 87% self-consumption, representing an estimated saving of between €1,500 and €3,000 per year.

Installation

• ⚠️ Cannot be installed in Belgium in single-phase mode (11,000 VA > Synergrid limit) — France and Luxembourg only
• Single-phase main circuit breaker (minimum 50A)
• Battery cabling rated for 220A — 95 mm² cross-section recommended depending on length
• Operates without a battery upon installation
• Commissioning via Deye commissioning guide

Main Screen

The LCD screen is touch-sensitive and displays general information about the inverter.

1 • The icon in the centre of the home screen indicates that the system is operating normally. If it displays "comm./F01~F64", this means the inverter has communication errors or other faults. The error message will appear below this icon (errors F01-F64; details of the errors can be viewed in the System Alarms menu).

2 • The time is displayed at the top of the screen.

3 • System configuration icon. Press this button to access the system configuration screen, which includes basic configuration, battery configuration, grid configuration, system operating mode, generator port usage, advanced functions and Li-Ion battery information.

4 • The main screen displays information regarding solar, grid, load and battery. It also indicates the direction of energy flow using arrows. When power approaches a high level, the colour of the panels changes from green to red, allowing system information to be clearly viewed on the main screen.

- PV power and charging power always remain positive.

- A negative grid power reading indicates power being sold to the grid; a positive reading indicates power being drawn from the grid.

- A negative battery power reading indicates charging; a positive reading indicates discharging.

Remote shutdown function

Smart monitoring platform

Thanks to the smart monitoring platform, the entire Deye series of inverters supports immediate remote shutdown in the event of a fault. Remote parameter adjustment and firmware updates facilitate the operation and maintenance of photovoltaic installations.
