Deye low-voltage three-phase hybrid family review
Deye SUN-14/15/16/18/20K-SG05LP3-EU-SM2 Hybrid Inverter Family
This official Deye family contains five 220/380 V or 230/400 V three-phase hybrid inverters rated 14, 15, 16, 18 and 20 kW. The current datasheet shows two MPPT trackers, two battery inputs, a 40-60 V lead-acid or lithium-ion battery window and model-dependent PV, AC and battery-current values. Select one complete suffix before quotation: the 28-40 kW maximum PV-access labels, 260-350 A charge/discharge limits and 15.4-22 kVA apparent-power values do not apply to every member.
Current source identity: official Deye SUN-14/15/16/18/20K-SG05LP3-EU-SM2 datasheet dated 2026-04-24, mapped to the same full family suffix on this catalogue page.

Current document status
A current family datasheet is available. The quotation still needs the exact member and suffix, destination-specific grid/certificate set, installation manual, approved battery and BMS/firmware record, meter/CT and generator wiring, parallel-system design, included accessories and applicable 5- or 10-year warranty terms.
Current family evidence
Keep five rated-power members and their limits in the same column
The official table supports a family shortlist, but every design value must be read from the selected member's column.
Five exact members
The family covers 14, 15, 16, 18 and 20 kW. Rated output, maximum apparent power, PV access/input power and battery current increase by member and must not be combined into one implied inverter.
Two-MPPT PV route
The table shows 800 V maximum PV voltage, 160 V start-up, 160-650 V MPPT, 36+36 A operating current, 54+54 A short-circuit current and 2+2 strings for the family.
Low-voltage battery route
The table states 40-60 V, two battery inputs and lead-acid or lithium-ion. The familiar 48 V label is shorthand, not a substitute for the operating window, current, protocol or approved battery list.
Grid, backup and enclosure
The source lists 3L+N+PE, 220/380 V or 230/400 V, 70 A AC pass-through, up to twice rated off-grid peak for 10 seconds, IP65, Wi-Fi/RS485/CAN and 51.9 kg.
Hybrid-inverter RFQ inputs
Six checks before fixing a SUN-SG05LP3-EU-SM2 member
PV, battery, backup load and destination approval must all map to the same exact inverter and firmware.
Exact member and destination
State the full 14/15/16/18/20K model, country, utility, AC voltage/frequency, grid code, export-control rule and required certificate revision.
PV strings per MPPT
Provide module Voc/Vmp/Isc/Imp, quantity, string allocation, minimum temperature, orientation and DC/AC target; verify voltage and both operating and short-circuit current limits.
Battery and BMS pairing
Provide exact battery model, usable energy, 40-60 V behavior, continuous/peak current, CAN/RS485 protocol, firmware, approved-list evidence and planned parallel layout.
Backup and pass-through loads
List continuous and startup W/VA by phase, imbalance, motors, transfer requirement, autonomy, grid pass-through demand and any generator-backed circuits.
Controls and parallel scope
Confirm meter/CT, zero export, generator port and control, time-of-use, communications, monitoring hardware and the design/accessories for any multi-inverter installation.
Files and commercial control
Request the matching datasheet/manual, battery list, grid and safety certificates, warranty, accessories, packing, serial traceability, quantity, lead time and substitution rules.
Compatibility and approval boundaries
Family maxima and BMS wording do not prove a complete hybrid system
The official table is strong product evidence, but site performance and approval remain configuration-specific.
Values vary by member
Do not assign 40 kW PV access, 350 A battery current or 22 kVA apparent power to the 14 kW member; use the selected column and temperature/installation conditions.
BMS self-adaption is not an approval list
The phrase does not identify compatible battery models, protocol version, firmware, current sharing, warranty acceptance or commissioning settings.
Backup claims need a load basis
The 10-second peak and 100% unbalanced-output wording do not prove that a particular motor, phase allocation or whole-site load will start and run.
Certification and warranty are scoped
Grid labels and downloadable certificates must match the full model, firmware and destination. The source says warranty duration depends on the final installation site and policy.

Questions to close before releasing the exact member
The full member, battery pair, PV strings and destination documents should agree.
Is this one 14-20 kW inverter?
No. It is a five-member family. Choose one exact 14, 15, 16, 18 or 20 kW model and use the matching values in that member's datasheet column.
Can any 48 V battery be connected?
No. The official 40-60 V window does not prove protocol or warranty compatibility. Confirm model, current, BMS protocol, firmware, approved-list status and settings.
Does the 10-second peak guarantee motor starting?
No. Provide startup current, duration, power factor, phase allocation and voltage-dip tolerance and check the exact overload curve and system configuration.
What should the quotation identify?
Require full model/suffix, PV string schedule, battery/BMS pair, backup and generator design, meter/CT, firmware, destination certificates, accessories, warranty and current documents.
Build an exact SUN-SG05LP3-EU-SM2 quotation
Send the required kW member, PV string data, battery and firmware, backup loads, destination grid, controls, documents and quantity for a model-specific review.
Start with the product, application or project information you have. We can help identify the remaining configuration, document or delivery questions before a final quotation.
