1.3. Safety Instructions
Be sure to read this manual thoroughly before installation.
Do not attempt to install the inverter by yourself. Installation work must be carried out in compliance
with national wiring standards and by suitably qualied personnel only. Do not turn on the power until all
installation work is complete.
Do not disassemble the inverter. If you need repair or maintenance, contact a professional service cen-
tre.
Always use an individual power supply line protected by a circuit breaker and operating on all wires with
a distance between contacts of at least 3mm for this unit.
The unit must be correctly grounded, and the supply line must be equipped with a suitable breaker and
RCD to protect people.
Disconnect all wires/cables before performing any maintenance or cleaning to reduce the risk of electri-
cal shock.
The unit is not explosion-proof, so it should not be installed in an explosive atmosphere.
Never touch electrical components immediately after the power supply has been turned o since the
system can still have residual energy, so an electric shock may occur. Therefore, after turning o the
power, always wait 5 minutes before touching electrical components.
This unit contains no user-serviceable parts. Always consult an authorised contractor for repairs.
1.4. Disposal Remarks
DO NOT dispose this product with domestic waste!
Electrical devices should be disposed of in accordance with regional directives on electronic and/ or elec-
tronic-waste disposal. In case of further questions, please consult your supplier. In some cases, the supplier
can take care of proper disposal.
WARNING
HIGH LIFE RISK DUE TO FIRE OR ELECTROCUTION.
The Sunsynk Ecco Hybrid Inverter can only be installed by a qualied licensed electrical contractor.
This is not a DIY product.

Supporting Wi-Fi or GSM monitoring
Visual power ow screen
Parallel / multi invert function grid-tied and o-grid
COMPATIBLE
Compatible with main electrical grid voltages or power generators
Compatible with wind turbines
Self-consumption and feed-in to the grid
Auto restart while AC is recovering
Auto earth bond feature (Via a relay)
CONFIGURABLE
Fully programmable controller
Programmable supply priority for battery or grid
Programmable multiple operation modes: on-grid/o-grid & UPS
Congurable battery charging - current/voltage based on applications by LCD setting
Congurable AC / solar / generator charger priority by LCD setting
SECURE
