February 15, 20215 yr Hi all. This is my first and very big install. I am putting 20x 455W panels per Sunsynk. Splitting to 2 strings (5 in series and those 2 in parallel). In total 60 panels, 3x Sunsynk 8Kw inverters and 3x 30 Kva Freedom won batteries. I can’t find any info how to program Sunsynk to run master and slaves.
February 15, 20215 yr Author Had to extend my roof to fit all the panels. Still waiting on the inverters(no stock now).
February 15, 20215 yr There are some YouTube videos on the Sunsynk channel where Keith Gough talks through the paralleling settings.

February 23, 20215 yr Hi, Did you win? I have done 3 phase the only difference would be that you now have one master and the other two are slaves.
February 23, 20215 yr Author Not yet. I am allmost finished with installation. Will let you know in a day or 2.

The 3 batteries was just too little to run system through the night so installing another 30kw battery. Will keep you informed.

What are you running there that 3 x 30kw aren't enough? How are pv production with all 60 panels?
March 24, 20215 yr So, a question on the battery set up there... If running in parallel there, the main inverter discharge current. Is that the TOTAL discharge current or is that per INVERTER? I have 2x 5kW and the discharge is set to maximum, so would that mean max discharge is 2x100A or limited to the main inverter 100A? I am taking comfort that the BMS comms work, so I would assume that would take presidence.

The total discharge current is per inverter.
