Hi Guys 

 

Having spent the last few months trying to get my generator working and have a solution (to my problem at least) and seeing as there seemed to be quite a few people with similar issues I thought some of you would find it useful. 

My Inverter would connect to the generator, apply a bit of load for a few seconds and then disconnect and try again 60 seconds later. 

By changing with the settings on the inverter a bit I could get it to connect at a low power (500W) load for a few minutes sometimes but it would always be a case of connect/diconnect every few minutes. 

I tried connecting to my inverter using both a transfer switch to switch between Eskom & Generator & the AUX port made little/no difference. 

 

I got my installer to come and sort out my earth bonding on the inverter, which they did not do for some strange reason when they did the initial install. 

I had to use my generator two nights ago as we had a power outage for 2 days due to a transformer issue and was able to pull 4kw from my inverter without it kicking out which was fantastic. 

Only issue I do still have is that my LED lights do tend to flicker slightly when running on the generator, I suspect that this may be a frequency issue as the generator runs at 48hz when under load so am going to push that up to over 50hz

Hi 

Glad you are finally getting somewhere, it can be so frustrating..

• So you now bonded Neutral and Earth coming out of the Sunsink Load Port ? (I'm setup Like that)
• Are you now feeding the Sunsynk Inverter from Generator via the Gen Port ?
• What bonding did you do on the Generator Side ?
• Do you think reducing Gen Input load below 5kva wil work ?
  • See My post where I am trying to get info:

 

 

 

Regarding the bonding, have no idea, my installer set it up.

Generator is feeding in via the mains power in as there is a transfer switch which switches between Eskom/Generator.

I am using the power shaving setting to limit the amount of power it is pulling over the connection and have it set at 4kw, if I go over that it trips out. 

I have a 5.5Kva Chinese generator so 4kw sounds fair in Johannesburg considering the altitude & age of generator.  

I started of the connection at 1kw and gradually raised it till it started tripping out.

 

 

 

 

If you bring down your shaving kw, what happens to you frequency? Maybe this can solve your flickering problem?

I have a couple of digital Swan panel meters which shows V, A and frequency it works very well except I  think the Frequency meter is pinned at 50Hz as I've never seen it going anywhere except 50. LoL

Glad that you got it sorted. Power shaving is indeed useful, especially when you are feeding in from the grid side and not the Aux.
