Fault & error codes — DYNESS Cygni

Extracted from the installation manual

12 documented

Showing 12 of 12. The official install manual is the authoritative source — always confirm before acting.

E1criticalCall your installer
Manual (PDF)
GFCI Fault (The ground leakage current is high)
Likely cause
Neutral & ground cables are not connected well on the AC side or just occasional failure.
What to do
Check using a multi-meter if there is a high voltage (normally should be lower than 10V) between the N&PE cable on the AC side.
E12criticalCall your installer
Manual (PDF)
DC Bus High (BUS voltage is over-high)
Likely cause
PV or battery voltage is too high.
What to do
Try to restart the product, and check if it still happens; if not, it means it is just an occasional situation.
E19criticalCall your installer
Manual (PDF)
ISO Fault (PV isolation protection)
Likely cause
Isolation failure could be caused by multi reasons like PV panels not grounded well, DC cable is broken, PV panels are aged or surrounding humidity is comparatively heavy.
What to do
Use a multimeter to check if the resistance between the earth & product frame is about zero. If not, please make the connection earth & product frame well.
E10warning
Manual (PDF)
Grid Loss (Not available of public grid power)
Likely cause
Product does not detect the connection of grid or the grid voltage fault.
What to do
Check connections and grid switch to ensure grid power is available.
E14warning
Manual (PDF)
Over Temperature (Temperature inside of the product is too high)
Likely cause
Product working environment leads to a high-temperature condition.
What to do
Check the product surrounding ventilation. Check if there's sunshine direct on the product in hot weather.
E16warning
Manual (PDF)
DC Input High (PV or battery voltage is too high)
Likely cause
The total voltage (open circuit voltage) of each PV string is higher than the max DC input voltage of the product.
What to do
Check the PV input voltage. Do not exceed the range of specifications.
E20warning
Manual (PDF)
DC Injection High (High DC injection current)
Likely cause
Product detects a higher DC component in AC output.
What to do
Try to restart the product, and check if it still happens; if not, it means it is just an occasional situation.
E21warning
Manual (PDF)
Back-Up Over Load (Back-up side is overloaded)
Likely cause
The total Back-Up load power is higher than the nominal backup output power.
What to do
Check if the load of the backup port is over-rating output power or not. Reduce the load of the backup port, then restart the product.
E25/26warning
Manual (PDF)
VAC High/Low (Grid voltage is not within permissible range)
Likely cause
Product detects that the AC voltage is beyond the normal.
What to do
Check the AC voltage is in the range of standard voltage in the specification.
E27/28warning
Manual (PDF)
FAC High/Low (Grid Frequency is not within permissible range)
Likely cause
Product detects that Grid frequency is beyond the normal range required by the safety country.
What to do
Check whether frequency is in the range of specification or not.
E31warning
Manual (PDF)
EEPROM Fault (EEPROM R/W fails)
Likely cause
Caused by a strong external magnetic field etc.
What to do
Try to restart the product, and check if it still happens; if not, it means it is just an occasional situation.
E32warning
Manual (PDF)
Comm Fault (Internal communication fails)
Likely cause
Caused by a strong external magnetic field etc.
What to do
Try to restart the product, and check if it still happens; if not, it means it is just an occasional situation.

WA Battery Scheme eligibility

Check eligibility

Synergy SSL inverter pairing, VPP participation and state-rebate qualification for this battery. Rebate and STC amounts are shown in the pricing panel.

CSIP-AUS compliant
Inverter must be CSIP-AUS compliant under the current WA framework.
Synergy SSL approved inverter
Needs pairing with a Synergy SSL approved inverter.
VPP activation ready
VPP activation requires a Synergy SSL approved inverter.
WA Battery Scheme rebate
Requires Battery Rewards participation under the current WA framework.
Synergy Battery Rewards
Requires a CSIP-AUS compliant system and reliable internet.
Interest-free loan
Not eligible for interest-free financing.

Under current WA rules, new rebate applications require VPP enrolment and CSIP-AUS compliance. How the scheme works · Estimate VPP earnings

Perth pricing

Typical installed price

$29,547

WA State RebateSubject to eligibility

Federal STCs-$6,264

After Rebates~$23,283

Prices are estimates. Final pricing depends on installation requirements. STC value is based on the current certificate price of about $39.9.

The WA Battery Scheme rebate (up to $1,300) requires a Synergy-approved (SSL) inverter and VPP enrolment — not all systems qualify, so it is not included above. Confirm eligibility with your installer.
