| Type | Hybrid Inverter |
| Style | 3-phase inverter |
| Manufacturing number | SUN-15K-SG05LP3-EU-SM2 |
| Extra heavy | Yes |
The Deye SG05LP3-EU-SM2 series is a range of three-phase hybrid inverters supporting low-voltage (48 V) batteries, designed for residential and light commercial solar systems.
The series covers power ratings from 3 kW up to 18 kW, with the specific models 5K, 6K, 8K, 10K, 12K, 15K, 16K, and 18K corresponding to model numbers SUN-3/4/5/6/8/10/12K-SG05LP3-EU-SM2 and SUN-14/15/16/18/20K-SG05LP3-EU-SM2, according to Deye’s official documentation.
These inverters intelligently manage energy by combining power from photovoltaic panels, batteries, and the grid to ensure a reliable and efficient power supply — even during grid outages. They also support AC coupling, allowing integration into existing solar systems.
Key Features
Hybrid functionality: Configurable for on-grid, off-grid, and backup applications. Can also store energy from a diesel generator to ensure continuous power supply.
Optimal solar energy harvesting: Two independent MPPT trackers maximize solar output under varying conditions or panel orientations.
Low-voltage battery support: Compatible with 48 V lead-acid and lithium-ion batteries; transformer-isolated design ensures enhanced safety.
Efficiency: PV > 97.6 % / Battery round-trip > 95 %.
Smart energy management: Up to six programmable time periods for battery charging/discharging, allowing tariff-based optimization.
High scalability: Parallel operation of up to 10 units for both on-grid and off-grid configurations.
Three-phase unbalanced output: Supports 100 % unbalanced load; each phase can handle up to 50 % of rated power.
Durable design: IP65 protection against dust and water, suitable for outdoor use; operating temperature −40 °C to +60 °C.
Comprehensive protection: Reverse DC polarity, AC overcurrent/overvoltage, thermal, DC component, and ground-fault current monitoring.
Remote monitoring: RS485, RS232, CAN communication; optional Wi-Fi, GPRS, or 4G dongle for Deye Cloud connectivity.
IT: VOLEVO SAPERE SE E' COMPATIBILE CON LA BATTERIA LHITIUM VALLEY LV-BAT-W10.24Ac 10.24kWh . GRAZIE"
EN: I WANTED TO KNOW IF IT'S COMPATIBLE WITH THE LHITIUM VALLEY LV-BAT-W10.24Ac 10.24kWh BATTERY. THANK YOU.
Italian:
Sì — il Deye SUN-15K-SG05LP3-EU-SM2 è compatibile con la serie Lithium Valley LV-BAT-W, quindi anche con la LV-BAT-W10.24Ac (10,24 kWh), a condizione di configurare correttamente comunicazione e limiti di corrente.
Sistema 48 V (51,2 V nominali): inverter e batteria lavorano nella stessa “classe” di tensione.
Comunicazione BMS: normalmente CAN (consigliato) e/o RS485 per lo scambio dati tra BMS e inverter.
La LV-BAT-W10.24Ac è 200 A continui in scarica: a 51,2 V sono circa ~10 kW.
Un inverter da 15 kW può richiedere più potenza/corrente dalla batteria, quindi:
On-grid (con rete): spesso va bene perché la rete può “aiutare” quando serve più potenza.
Backup/EPS o off-grid: se chiedi più di ~10 kW solo dalla batteria, l’impianto può limitare la potenza o il BMS può intervenire. In questi casi conviene mettere 2 batterie (o più) in parallelo oppure limitare la potenza EPS.
Aggiorna firmware inverter (e batteria se previsto).
Collega CAN tra batteria e inverter (di solito è l’opzione migliore).
Nel menu Deye: Battery = Lithium e seleziona il protocollo/brand BMS corretto.
Imposta limiti di carica/scarica coerenti con la batteria (se la comunicazione non è stabile, limita manualmente).
English:
Yes — Deye SUN-15K-SG05LP3-EU-SM2 is listed as compatible with Lithium Valley LV-BAT-W series, and Lithium Valley LV-BAT-W10.24Ac falls under that series.
Inverter battery side: 48 V-class, battery voltage range 40–60 V, “self-adaption to BMS”, comms RS485/RS232/CAN.
Battery: 51.2 V, 200 Ah, 10.24 kWh, charge cut-off 56.16 V / discharge cut-off 45.6 V, comms CAN + RS485.
The LV-BAT-W10.24Ac is 200 A continuous discharge.
That’s roughly ~10 kW at ~51.2 V. A 15 kW inverter can demand more battery current (Deye lists up to 300 A for this platform).
So:
On-grid: the grid can assist; you may still be fine depending on settings and loads.
EPS / off-grid: if loads exceed what the battery can supply, the system may power-limit or the battery BMS may trip unless you add 2+ batteries in parallel (or cap EPS power).
Update inverter firmware (and battery if applicable).
Wire CAN (recommended) between battery and inverter; RS485 usually for parallel battery links.
In Deye menu: set Battery = Lithium and select the correct BMS/brand protocol per the Deye approved list / installer settings.
Set charge/discharge current limits so they don’t exceed battery capability if comm is not stable (battery max charge current depends on temperature; see datasheet).
SONO INTERESSATO AL MODELLO 15k MA L'INSTALLATORE MI CHIEDE SE HA LA CERTIFICAZIONE PER ESSERE VENDUTO IN ITALIA. MI CHIEDE LA CERTIFICAZIONE
CEI 0-21.
GRAZIE MILLE
I'M INTERESTED IN THE 15kW MODEL, BUT THE INSTALLER ASKS ME IF IT'S CERTIFIED FOR SALE IN ITALY. HE'S ASKING ME FOR CEI 0-21 CERTIFICATION. THANK YOU VERY MUCH.
ITALIAN:
Sì — SUN-15K-SG05LP3-EU-SM2 è coperto da una dichiarazione di conformità CEI 0-21 per l’Italia, quindi è previsto/accettabile per la connessione alla rete BT in Italia, a condizione che l’unità installata corrisponda a hardware/firmware coperti e che sia configurata secondo il codice di rete italiano.
Una Dichiarazione del Produttore (Italia) elenca esplicitamente SUN-15K-SG05LP3-EU-SM2 (insieme a 14/16/18/20K) e dichiara la conformità a CEI 0-21:2022-03 + V1:2022-11 + V2:2024-01; fa anche riferimento alla documentazione di prova e indica firmware Ver 1148.
La pagina prodotto ufficiale Deye per la serie SUN-14/15/16/18/20K-SG05LP3-EU-SM2 riporta CEI 0-21 tra le normative di rete supportate.
Firmware: assicurati che il firmware dell’unità corrisponda a quello coperto dalla dichiarazione (viene citato Ver 1148).
Impostazione codice di rete: in fase di configurazione/commissioning, seleziona il profilo rete Italia / CEI 0-21.
Documentazione: fornisci all’installatore/DSO la dichiarazione CEI 0-21 (e, se richiesto, esporta dal menu dell’inverter il report/test CEI 0-21 — molti distributori lo richiedono).
ENGLISH:
Yes — SUN-15K-SG05LP3-EU-SM2 is covered by a CEI 0-21 conformity declaration for Italy, so it’s intended/acceptable for LV grid connection in Italy as long as the installed unit matches the covered firmware/hardware and is configured to the Italy grid code.
A Manufacturer’s Declaration (Italy) explicitly lists SUN-15K-SG05LP3-EU-SM2 (together with 14/16/18/20K) and declares conformity with CEI 0-21:2022-03 + V1:2022-11 + V2:2024-01; it also references testing documentation and notes firmware Ver 1148.
Deye’s own product page for the SUN-14/15/16/18/20K-SG05LP3-EU-SM2 series lists CEI 0-21 among the supported grid regulations.
Firmware match: ensure your unit’s firmware corresponds to what the declaration covers (it mentions Ver 1148).
Grid code setting: in commissioning, select the Italy / CEI 0-21 grid profile.
Paperwork: provide the installer/DSO the CEI 0-21 declaration (and if requested, export the inverter’s CEI 0-21 self-test/report from the menu—many DSOs/portal workflows ask for it).
