When using the parallel system, the inverter settings and notes please refer to
this manual<6.3.2 Advanced setting → 6.Parallel setting>.
Note(AC LOAD is also parallel for parallel machines):
1. The first and last inverters need to be connected with 8Pin connection
terminals.
2. The cable length of the AC LOAD terminal connected from the LOAD
terminal to each machine shall be consistent with the specification of the cable
length, so as to ensure that the loop impedance is consistent and the current of the
LOAD current diverted to each machine is nearly equal.
3. When the total power of AC Load is greater than 110% of the rated
power of the machine
（
For example, one inverter AC LOAD has a maximum
allowable power of 5.5kVA and six parallel machines AC LOAD has a maximum
allowable power of 33kVA
）
, the Load should not be connected to AC Load and
should be connected to AC Grid.
4. When inverters in parallel, All AC gird should be Shared a total air
switch; All AC LOAD should be Shared another total air switch .
