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 qualified 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 centre.
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 electrical 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 off since the system can still have residual energy, so electric shock may
occur. Therefore, after turning off 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 electronic-waste disposal. In case of further questions, please
consult your supplier. In some cases, the supplier can take care of proper disposal.
HIGH LIFE RISK DUE TO FIRE OR ELECTROCUTION.
The Sunsynk Three-Phase Hybrid Inverter can only be installed by a qualified
licensed electrical contractor. This is not a DIY product.

2. PRODUCT INTRODUCTION
The Sunsynk Three-Phase Hybrid Inverter is a highly efficient power management tool
that allows the user to hit those ‘parity’ targets by managing power-flow from multiple
sources such as solar, mains power (grid) and generators, and then effectively storing
and releasing power as and when utilities require.
