Safety
The inverter has been designed and tested strictly according to international safety regulations.
Read all safety instructions carefully before any work and observe them at all times when
working on or with the inverter.
Incorrect operation or work may cause:
Injury or death to the operator or a third party, as well as damage to the inverter and other
properties, may occur.
Warning
Any installation or operations on the inverter must be performed by qualied electricians
in compliance with standards, wiring rules and the requirements of local grid authorities or
companies
Never insert or remove the AC or DC connections when the inverter is running.
Before making any wiring connections or performing electrical operations on the inverter, all DC
and AC power must be disconnected for at least 5 minutes to ensure that the inverter is totally
isolated to avoid electric shock.
The temperature of the inverter surface can exceed 140
o
F during operation. Ensure it has cooled
down before touching it and the inverter is out of reach of children.
Do not open the inverter cover or change any components without the manufacturer's
authorization. Otherwise, the warranty for the inverter will be invalid.
The usage and operation of the inverter must follow the instructions in this User Manual.
Otherwise, the protection design might be impaired, and the warranty for the inverter will be
invalid.
Appropriate methods must be adopted to protect the inverter from static electricity damage.
The manufacturer does not provide warranty for any damage caused by static electricity.
PV negative (PV-) and battery negative (BAT-) on the inverter side are not grounded as the
default design. Connecting either PV- or BAT- to EARTH is strictly forbidden.
The inverter, with a built-in RCMU, will prevent the possibility of DC residual currents up to 6mA.
Thus, in the system, an external RCD (type A) can be used (≥30mA).
