Nick De Jong Posted December 15, 2021 Share Posted December 15, 2021 Hi Guys I have just upgraded to a 12kw Sunsynk 3 phase inverter. Problem is my generator is only single phase. Can I still use it on this inverter to supply my load (UPS - which I am only drawing single phase off) In other works can I still wire it up to the Gen input at N and L1 the I only draw off N and L1 on my Load ??? appreciate any feedback.

1 Leshen Posted January 27, 2022 Share Posted January 27, 2022 Unfortunately not. You will need a 3 phase generator. Yellow Measure 1 Quote Link to comment Share on other sites More sharing options...

Cheers Nick Benoni SA Hi ... I would also like to know the answer to this. If the generator is connected like this, can it charge the battery if the load is less than the generator capacity?

0 Mauritius B Posted January 31, 2022 Share Posted January 31, 2022 (edited) You can use a 1phase to 3phase converter but it might be more expensive than a new generator. Edited January 31, 2022 by Mauritius B Quote Link to comment Share on other sites More sharing options...

0 Sc00bs Posted March 23, 2023 Share Posted March 23, 2023 As far as I am aware (I could definitely be wrong here) @Scorp007 I think that it is the same thing, 220V is from any of the phases to Earth and it is 380V between the phases Quote Link to comment Share on other sites More sharing options...

I could not download any of the links. Those that I have seen you have to reconnect the motor to delta as the output is 220V between phases if 220V 1ph is given as an input. They also only give a 3 wire output and not 4 wire. Edited March 24, 2023 by Scorp007 Quote Link to comment Share on other sites More sharing options...
0 iiznh Posted March 24, 2023 Share Posted March 24, 2023 @Nick De Jong So thinking out of the box here but you could use the gennie with a suitable 220V battery charger (if you can find one large enough) and charge the battery directly bypassing the inverter completely. If the battery BMS has a coulomb counter it should still report the correct battery SoC P1000 1 Quote Link to comment Share on other sites More sharing options...
0 Sc00bs Posted March 24, 2023 Share Posted March 24, 2023 @Scorp007 Best probably to speak to the supplier and find out from them what the situation is. Quote Link to comment Share on other sites More sharing options...

Expect to pay upwards of R13000 for one of about 80-100A on the 48V side. Rather buy a Axpert and use only the charger. Hahaha.

0 Denveronly Posted March 25, 2023 Share Posted March 25, 2023 m starting with a 3 phase invertor right now too and the question is can i run my 1 phase generator which powers the whole house 3 phases (fake three phases just a 220volts on every phase from gens 1 phase so it could power up Inverter (all three phases would be that fake i told before) so the inverter charges the battery? or i only need a 3 phase generator and there is no way of charging a 3ph Inverter with a 1 phase gen (options are: gen current goes to inverter grid, gen current goes to inverter aux-gen input, gen current goes to aux -mikroinverter Quote Link to comment Share on other sites More sharing options...
0 darrellok Posted March 31, 2023 Share Posted March 31, 2023 I have a 12 kva 3 phase Sunsync inverter and I use a single phase genie to charge the batteries when I need. It switches on and off accorcing to the paramaters that you set on the app works like a bomb. tdovale 1 Quote Link to comment Share on other sites More sharing options...
0 DewaldF Posted April 20, 2023 Share Posted April 20, 2023 Hi, I have a 3 phase generator 35kva (Kipor) with a automatic transfer switch and smart Gen controller. At the moment I have opted for a single phase 8 KVA Sunsynk inverter which can be expanded to a 3 phase system later ( each inverter doing one phase) My idea is to rewire my Db board for essential loads on one phase and non essential loads on the other phases for now. Can I use my 3x phase Gen to integrate with my one phase inverter for now. Eg If the batteries run flat the generator will then start to charge the batteries according to % set. The obvious drawback is that the non essential loads will not have power if there is loadshedding Any ideas ? Or advise Quote Link to comment Share on other sites More sharing options...

It is CN2 Grid Ry 5 & 6 I think. I am also busy with my installation and have not tested yet but I believe these are the ones.

0 Chris Olivier Posted November 18, 2023 Share Posted November 18, 2023 If you have a parallel system with 3x 8kwatt 1phase sunsynk inverters will you be able to ran one 1phase Generator to only one inverter gen input to regarge bTteries will that work or will the inverter coms pick up 2 missing fases ?

Question
Nick De Jong
Hi Guys
I have just upgraded to a 12kw Sunsynk 3 phase inverter. Problem is my generator is only single phase.
Can I still use it on this inverter to supply my load (UPS - which I am only drawing single phase off)
In other works can I still wire it up to the Gen input at N and L1 the I only draw off N and L1 on my Load ???
appreciate any feedback.
Cheers Nick
