Deye SUN-10K-SG05LP3-EU-SM2 10 kW Three-Phase Hybrid Inverter

The Deye SUN-10K-SG05LP3-EU-SM2 is a 10 kW three-phase hybrid inverter for 48 V low-voltage batteries. It joins two MPP trackers, a 210 A battery port and a backup output in a 35 kg wall unit, and it keeps the battery side isolated by a transformer. It suits villas, farms and small commercial premises with a 400 V three-phase supply that already use, or prefer, 48 V storage.

Low-voltage storage on a three-phase supply

Many installers favour 48 V racks because the batteries are widely available and safe to handle. Pairing them with a three-phase inverter gives a balanced connection to the building and lets each phase of the backup output deliver up to half the rated power, a feature the datasheet describes as 100% unbalanced output. Time-of-use slots, generator support and AC coupling are all part of the platform, so the same hardware can serve a new system or an upgrade of an existing array.

Datasheet highlights

• 48 V battery with transformer isolation.
• Up to 10 inverters in parallel, with several batteries.
• Six programmable charge and discharge periods.
• Generator energy can be stored; PV can be added on the AC side.
• Output per phase up to 50% of rated power in backup mode.

Choosing the 10 kW rating

The 10K sits one step below the top of the family. It has the same enclosure as the 3 kW unit, so the question is simply how much power the site needs. Its 16.7 A maximum AC current is modest for three phases, which keeps the cable and breaker small. The battery current of 210 A is the number to check against the cable and the battery rack, because a 48 V system carries large DC currents.

Wiring points from the user manual

For this family the manual lists 1 AWG (42 mm2) battery cable at 24.5 Nm for the 5 to 12 kW models and 8 AWG (6 mm2) AC cable at 1.2 Nm for the 10 and 12 kW. It recommends 63 A breakers on both grid and load ports, and three CTs, one on each of L1, L2 and L3, for the zero-export mode. Allow about 50 cm of clearance, avoid humidity above 95% and direct cold air, and do not stand the unit on bare hard ground.

Hot-climate siting

A three-phase hybrid with a 48 V rack beside it concentrates heat and current in one corner. Keep the battery cables short, shade the wall and plan ventilation for both units. Because output derates above 45 degrees C, a plant room with an extractor is better than an exposed outdoor wall in summer.

Quick sizing arithmetic

At 210 A and a nominal 48 V the battery port handles about 10 kW, matching the AC rating, and 16000 W of rated PV input is 1.6 times the AC power. The unit weighs 35.2 kg and measures 386 x 660 x 250 mm. Since the datasheet allows ten inverters in parallel, a site can start with one 10K and add units later, provided the batteries and the CT arrangement are planned for the final system.

Selection and installation notes

A hybrid inverter is selected from the PV array voltage and power, the battery voltage and chemistry, the backup load and the grid connection. Check that the string open-circuit voltage at the lowest site temperature stays below the input limit, that the battery is on the maker approved list with the right communication cable, and that the backup loads fit the rated output. Install in a shaded, ventilated place with the clearances on the data sheet, use DC isolators and surge protection, and have the grid settings approved by the local utility before connection.

Documents and supply information

The manufacturer data sheet is attached to this page and should be read together with the project specification and the site risk assessment before a purchase is confirmed. Ratings, standards and dimensions are quoted as printed on that sheet. Lead time, stock position and certificates available with the shipment are confirmed in the quotation, and we supply to Oman and the wider GCC region for industrial, utility and building services projects.

Frequently asked questions

What is the rated output of SUN-10K-SG05LP3-EU-SM2?

10000 W three-phase, 11000 VA maximum, at 220/380 or 230/400 V.

Which battery voltage does it use?

40 to 60 V lead-acid or lithium-ion, with 210 A maximum charge and discharge current.

How many can be paralleled?

Up to 10 inverters for on-grid and off-grid operation.

What does 100% unbalanced output mean?

Each phase may carry up to 50% of the rated power, so single-phase loads can be served in backup mode.

Why is the datasheet attached instead of the manual?

The manual is marginally above the size we host, so request it if you need the wiring tables.
