quently Asked Questions www.sunsynk.com. Firmware prior installation is important to be updated and all
inverters in parallel or three phase system must be the same.

Some common questions that occur when paralleling inverters:

Q1: What is the sequence to install/connect/commission?

First of all, leave the main supplies off. Next, connect all communication cables, set up all LCDs and then, last
of all, turn on the main supplies.

Q2: What are the indications that the communication and the system are ok or not?

Parallel errors will be shown as fault F46 on the display.

Q3: What are the consequences of not setting one inverter in a parallel mode?

It can damage the inverter.

Q4: What are the consequences of having more than one Master Inverter or having no inverter set as
‘Master’?

It can damage the inverter. There are cases in which it is possible to have more than one master. For exam-

ple, as aforementioned, six inverters paralleled in a three phase utility grid (three masters).

Q5: What are the consequences for setting A, B, or C phases wrong while in parallel mode?

It can damage the inverter. Recommend checking the phase rotation with a meter before switching on.

Q6: What are the consequences of factory resetting, power cycling, or firmware updating one invert-
er in a parallel system?

It can damage the inverter. Inverters needs to be isolated from each other before factory reset or firmware

update.

Q7: What consequences for changing ALL/ANY settings while operating in parallel mode?

It can damage the inverter and fault F46 will be indicated on the display.
