No load can be directly connected to the output side of the inverter.
Installation
Recommended Voltage/Current for DC Breaker is 600V/25A.
Recommended Voltage/Current for AC Breaker is 270V/35A.
If the inverter is equipped with the “AC Breaker including the RCD”, the
parameter of the RCD refers to the following:
Danger
Warning
3.6 Electrical connection
After the inverter is correctly installed on the wall or support, the next step is the
electrical connection for the inverter. Electrical connection must be performed
according to related safety standards.
A misoperation electrical connection may cause personal injury or
death or damage the inverter irreversibly. Wiring operation must be
performed by a qualified electrical engineer.
All electrical installation must be complying with local and national
electrical standards.
Warning
Warning
The inverter cannot be connected to the grid unless approved
by the local electrical authority and all electrical connections
are completed by a qualified electrical engineer.
Please use cables of specification recommended by us,
or the system safety may be deraded.
The electrical connection for an inverter covers electrical cable connection and
communication cable connection.
3.6.1 Electric and electrical system structure
The electric and electrical connection for the whole solar energy power
generation system is shown as below:
Fig.3-10
There are 2 independent MPP trackers in inverter. You can choose multi-strings
input connection(Fig3-11) and common-string input connection(Fig3-12). We
recommend that choose multi-strings to harvest max. PV power.
