Nameplate
Note: The MAC series inverter nameplate is similar to the nameplate shown above, but
the product model and specific parameters are different. See Chapter 10 Product
Specifications for specific parameters.
Mac inverter's working principle is like following:
1>The PV panels gather solar to generate DC power to inverter.
2>With input current detection circuit, it can monitor all the PV panels' working status
and use MPPT to track the maximum power point.
3>With inverter circuit change DC power to AC power, and feed power back to grid per
grid reuqirement.
4>With output isolation relay can isolate AC output and grid, if anything goes wrong on
either inverter side or grid side, isolation relay can disconnect inverter immediately.

1>Do not unpack the Inverter and store it in a ventilation dry place.
2>Keep the storage temperature at -25
℃
~ +60
℃
and humidity at 0-95%.
3>A maximum of four inverters with package can be stacked.
4>If the inverter has been long-term stored, inspections and tests should be conducted
by qualified personnel before it is put into use.
In the MAC series, the MAC 30-60KTL3-X LV model grid connection method is shown in
Figure 3.3, and the MAC 50-70KTL3-X MV model grid connection method is shown in
Figure 3.4,and the MAC 15-36KTL3-XL model grid connection method is shown in
Figure 3.5.
