DaveP Posted October 2, 2020 Share Posted October 2, 2020 Hi All I have been searching, but haven't been able to come up with a definite answer. Can the Sunsynk/Deye/Ohm 5kW inverters be setup to in parallel on a 3-phase network? i.e. 3 inverters (1 per phase) sharing the same battery? I have seen reference to being setup in parallel on one phase, but lacking info on 3-phases setup. Thanks in advance Quote Link to comment Share on other sites More sharing options...
Chloe Posted October 2, 2020 Share Posted October 2, 2020 Yes the Sunsynk can be set one per phase. Currently there's no 3 phase Sunsynk's on the market. Quote Link to comment Share on other sites More sharing options...

Thanks in advance Hi Dave yes the Sunsynk 5.5 and 8.8 Can be setup in 3 Phase The inverters each attach to a Phase and they have comms cables that they use to communicate with each other they share the same Battery bank be it Litium or Lead acid PM me your email address and I can send you the installer manual via email Quote Link to comment Share on other sites More sharing options...

Been looking for a 3-phase grid tied hybrid solution that uses a 48V battery system. Only 3-phase hybrids on CoCT approved inverter list use high voltage batteries. Will send you a PM for the manual, thanks. Quote Link to comment Share on other sites More sharing options...

LPvdM Posted April 7, 2021 Share Posted April 7, 2021 Hi all, I see this very old conversation. To ask a further question, id I may... I have bought three of the Sunsynk 5 kW inverters. I want to couple it for 3 phase. Will the coms cables goes from INVETER 1 (Master, A phase) = Parallel 2 plug, to INVERTER 2 (Slave, B phase) = Parallel 1 plug, then the Parallel 2 plug to INVERTER 3 (Slave, C phase) = Parallel 2 plug ????

Ussemane Jose Posted April 27, 2021 Share Posted April 27, 2021 Good afternoon, My name is Ussemane José From Mozambique, I want to know if Sunsynk does fabricate 3ph inverter from rang 8-40kW suitable for large houses Quote Link to comment Share on other sites More sharing options...

coffeedogsjujitsu Posted January 22, 2022 Share Posted January 22, 2022 Hi I know an old thread I want to build a 90kw system 3ph this is usually done using Victron Quattro's and a kak load of mppts and wiring. The Sunsynk 8.8 manual states max 3 per phase but Deye video says 5 per phase, I need 4per phase. Has anybody attempted this. The other way would be HV battery and inverter but there are no good brands on the inverter side yet. Freedom won do high voltage batteries Quote Link to comment Share on other sites More sharing options...

Also a Chinese brand seems they are thinking ahead. Quote Link to comment Share on other sites More sharing options...

This is simply not so. We should not be stuck around residential units. Synsynk makes a 12kw 3 phase unit and you can add up to 16 in parallel. Yes it is still running at 48V. As per the OP perhaps the grid tied 100kw 3 phase Solis can be used during the day and then switch the batteries charged via another inverter or may be the clever guys can indicate if batteries cannot be used in the place of panels via the MPPTs. My idea would be just to add a current limiter of say 10A per input. The Solis has 10 x MPPTs. Edited January 23, 2022 by Scorp007 Quote Link to comment Share on other sites More sharing options...
FixAMess Posted January 23, 2022 Share Posted January 23, 2022 Goodwe has a few high capacity inverters as well, might be worth your while contacting them. Quote Link to comment Share on other sites More sharing options...
