The Deye SUN-15K-SG05LP3-EU-SM2 with 2 × SE-G5.1PRO-B is a 15 kW three-phase hybrid inverter with two battery modules (10.24 kWh), made for a solar PV system of up to 24,000 W PV input. It differs from the 20 kW set only in the inverter: the batteries (10.24 kWh), dimensions and weight (50.6 kg) are the same, but PV input is lower (24,000 W against 32,000 W), maximum battery current is 280 A (not 350 A), and off the grid it can deliver 30 kW for 10 s (not 40 kW). Choose it when your PV array stays within 24,000 W; a larger plant or a higher peak demand calls for the 20 kW set.

How the Deye SUN-15K-SG05LP3-EU-SM2 set differs from the 20 kW set
| Parameter | 15 kW set | 20 kW set |
|---|---|---|
| Inverter rated power | 15 kW | 20 kW |
| Max. PV input power | 24,000 W | 32,000 W |
| Max. battery charge and discharge current | 280 A | 350 A |
| Off-grid peak power (10 s) | 30 kW | 40 kW |
| Battery energy in the set | 10.24 kWh | 10.24 kWh |
Choose this 15 kW set if your solar PV system stays within 24,000 W of PV and 30 kW of off-grid peak power is enough. For a larger plant, look at the 20 kW set. Both sets have the same 10.24 kWh of batteries, so the inverter is what decides.
Which hybrid inverter with battery suits a home or an off-grid system?
This set suits those who want to keep surplus solar energy for themselves and use it in the evening instead of sending it to the grid. The manufacturer’s datasheet lists several ways to use it:
- On-grid and off-grid systems
- Energy storage from a diesel generator
- AC coupling with an already operating solar PV system
- Several inverters in parallel, up to 160 units
How do the Deye battery and inverter fit together?
The set contains one Deye SUN-15K-SG05LP3-EU-SM2 and two SE-G5.1PRO-B modules. The inverter accepts 40–60 V low-voltage batteries. High-voltage and low-voltage systems are not compatible with each other.
How much energy does the set store, and how do I choose battery capacity?
The nominal energy of the set is 10.24 kWh (2 × 5.12 kWh).
How many modules suit your inverter and site, we calculate from your real consumption.
Running without the grid, with a generator and in parallel
Without the grid the inverter can briefly, for 10 s, deliver up to 2 × rated power, that is, 30 kW. An unbalanced three-phase load is allowed at 100% on each phase.
If the site has a diesel generator, the inverter supports energy storage from it. An existing solar PV system can be coupled on the AC side.
Home battery storage for a solar PV system: what ESO says
ESO (Lithuanian grid operator) states:
“Part of the surplus electricity generated can be stored in an energy storage device and used in the evening.”
ESO adds that a storage system reduces the power fed into the distribution grid, so in some cases a larger solar PV system can be connected than grid limits alone would allow.
We handle it for you. We select the equipment for your site, deliver anywhere in Lithuania, install and connect it.
