Dyness Cygni 10.0HS

Unknown Global (a separate AU-market manual and datasheet exist) verified Sept. 2, 2026

Unresolved safety-relevant conflict
Two sources give different figures for a value on this product and nobody has resolved it. The specifications below are shown as recorded, but this product must not be treated as verified for engineering purposes until the conflict is closed.

Identity

category all_in_one_ess
ean UNKNOWN
generation UNKNOWN
hardware_revision UNKNOWN
legacy_name UNKNOWN
manufacturer Dyness
market_version UNKNOWN
model Cygni 10.0HS
mpn UNKNOWN
product_family Dyness Cygni Series
product_status active
product_status_evidence Listed on the dyness.com residential Low Voltage ESS index with a live official product page, fetched 2026-09-02.
region Global (a separate AU-market manual and datasheet exist)
release_year UNKNOWN (earliest located official Cygni document is the AU datasheet/manual dated 2024-11-12; the global datasheet revision is 2025-10-20; no release year is printed)
sku UNKNOWN
subcategory stacked all-in-one residential ESS - hybrid (PV + battery) inverter plus stackable battery modules
variant_note Four published system variants share one enclosure set and differ in AC output power and coupling: 8.0HS (8000 VA, hybrid), 10.0HS (9999 VA, hybrid), 8.0AS (8000 VA, AC-coupled), 10.0AS (9999 VA, AC-coupled). This record is 'Cygni 10.0HS'. The AU user manual title additionally shows an '-M2/M3/M4' suffix that appears to encode the number of stacked battery modules; that document was located but not fetched.

Electrical

ac_nominal_output_power_va 9999
cell_chemistry UNKNOWN (not printed on the official page; the Cygni sits in the Dyness LFP residential range but chemistry is not stated for this model)
cell_type UNKNOWN
continuous_charge_current_a UNKNOWN
continuous_discharge_current_a UNKNOWN
continuous_power_kw UNKNOWN as a battery DC rating. The published '9999 VA' is the SYSTEM AC nominal output apparent power.
cycle_life >=8000 cycles
depth_of_discharge_pct UNKNOWN
max_charge_current_a UNKNOWN
max_charge_power_kw UNKNOWN
max_discharge_current_a UNKNOWN
max_discharge_power_kw UNKNOWN
max_parallel_units UNKNOWN
max_series_units UNKNOWN (battery modules stack; the stack count is disputed - see data_conflicts)
nominal_capacity_ah UNKNOWN
nominal_energy_kwh UNKNOWN (the official page publishes only a USABLE energy range for the system, not a nominal energy)
nominal_voltage_v UNKNOWN (no battery nominal voltage is published on the official page)
note SAFETY-CRITICAL DISTINCTION: '9999 VA' is AC apparent OUTPUT power of the inverter unit and is unrelated to the 7.68~46.08 kWh battery ENERGY range. Neither battery DC voltage nor any battery current is published; every such field is UNKNOWN rather than derived.
operating_voltage_max_v UNKNOWN
operating_voltage_min_v UNKNOWN
parallel_supported UNKNOWN
peak_charge_current_a UNKNOWN
peak_discharge_current_a UNKNOWN
peak_power_kw UNKNOWN
round_trip_efficiency_pct 94 (battery round-trip, per the Solar Link Australia installer review; not confirmed by Dyness)
series_supported UNKNOWN
system_energy_max_kwh 46.08 (disputed - see data_conflicts)
system_energy_min_kwh 7.68
usable_energy_kwh 7.68~46.08 (system range across the supported number of stacked battery modules) - CONFLICT, see data_conflicts

Physical / mechanical

cooling_method UNKNOWN
depth_mm 180 (both the inverter unit and each battery module)
height_mm 450 (inverter unit) / 300 (each battery module) - the assembled stack height depends on module count and is not published
installation_notes 'Wiring-free stack design' per the official page marketing copy.
ip_rating IP66
mounting_type ['stacked (wiring-free stack design)']
rack_units N/A (proprietary stack)
weight_kg 27.5 (inverter unit) + 40.5 per battery module - no single total system weight is published
width_mm 650 (both the inverter unit and each battery module)

Installation

indoor_outdoor indoor and outdoor (IP66)
installation_notes UNKNOWN
mounting_orientation vertical stack

Environment

charge_temperature_range_c UNKNOWN (no source splits charge from discharge for the Cygni)
discharge_temperature_range_c UNKNOWN (see above)
indoor_outdoor indoor and outdoor (IP66)
max_altitude_m UNKNOWN
operating_humidity UNKNOWN
operating_temperature_max_c 60 (per the Solar Link Australia installer review; not published by Dyness)
operating_temperature_min_c -20 (per the Solar Link Australia installer review; not published by Dyness)
storage_temperature_max_c UNKNOWN
storage_temperature_min_c UNKNOWN

Interfaces & connectors

bluetooth UNKNOWN
can UNKNOWN
communication_ports UNKNOWN (no communication interfaces are published on the official Cygni page)
dry_contact UNKNOWN
ethernet UNKNOWN
modbus_rtu UNKNOWN
modbus_tcp UNKNOWN
protocol_notes None published. The Cygni is a closed inverter+battery system, so third-party inverter protocol selection is not applicable in the way it is for the bare battery modules.
rs232 UNKNOWN
rs485 UNKNOWN
usb UNKNOWN
wifi UNKNOWN

Protection

fire_suppression yes - 'Built-in active fire protection system' per the official page
heating UNKNOWN
ip_rating IP66
over_current UNKNOWN
over_temperature UNKNOWN
over_voltage UNKNOWN
short_circuit UNKNOWN
under_voltage UNKNOWN

Certifications

confidence community-verified
note No certification is printed on the official dyness.com Cygni page. AS/NZS 4777.2 is an Australian grid-connection standard and would apply to the AU market version only.
safety_certifications UNKNOWN
