Sunsynk 5kw Inverter and 2 x MPPT

Can that cause the System not switch the load on . 

No it should switch on to normal mode regardless. The BMS comms to batteries are working so there must be some other fault . Is it still not in Normal mode? Not sure what else to say except if you can make a post with a picture of every setting screen we can maybe see something.

  • It will work. It'll be sub-optimal but possibly better than being below start-up voltage on the 4 panel option. 

  • So I can connect one array with 450 to MPPT 1 and another with 450 to MPPT 2? Concerning Amps, I believe the correct function is for the Inverter to draw the power it requires while keeping the Voltag

    With the new firmware the sunsynk5lw does 13 amps on the mppt's the clipping will be almost non-existent I have 540watt jasolar 6 in series on single mppt which has never gone above 12amps so those

If you check the pics, its not in normal mode, the BMS is running perfectly. The only setting i changed was the 74amps on the battery settings.

Have you switched off the inverter via the button on the bottom? After I made changes to my system last time, it also gave me an error message and did not go into Normal mode. Briefly switching off the inverters (after disconnecting load and PV) got everything working again. Seemed just to have been a hick-up...

I am following the switch and the switch on sequence in the manual. I am taking it out and sending it to Sunsynk repair centre so that they can check it up

Good day, 

I have a 5kw Sunsynk Duel MPPT and up to yesterday i had 1 Array 4360W connected to the inverter MPPT port 1, operating 100%.

Yesterday i connected the 2nd Array 3270W to the second port of the MPPT Port 2 on the inverter. Not exeeding any Max loads as per the Inverter specification sheet. 

After installation with fuses removed, the 2 x voltages at load side on the fuses are MPPT 1 = 341V and MPPT 2 = 262V, After starting the system up, and checking the display, only the newly installed Array Shows on the flow chart, and none on the Old MPPT flow Chart. 

All the panels are facing true North, I done 2 x "Strings" arrays not to Exceed the max VOC and Power. 

Is there a setting I need to change in the program to see both operating at the same time?

I have 8 455w Ja solar panels on a string , operating voltages are between 280-315v so for 4 of the panels you will be at about half of that.

@NexussWill you please post some watage screen shots of a good production day?
