Break in AC Output

I am little concerned about a couple of occasions where when the generator has kicked it there has been a momentary break in power, enough to cause everything to be turned off.

Is there any way of checking where the issue may be? Or are there any common issues like this and things I could check? The generator always kicks in when the conditions are met and is serviced regularly and seems to be running as usual.

Any help and advice would be most welcome.

Thank you. Paul

Or is it something to do with the inverter? I would like to think not as it was only installed in May. It’s a MultiPLus II 48|15000|200.

Could you please describe your problem in a little more detail?

And please describe your system setup a little so that readers here can understand.

There is always a delay in the transfer from inverter to shore power(generator). No delay in the transfer from shore to inverter.

Hi, well as above really. When the start/stop conditions set on the Ekrano are met then the generator does kick in. However, on couple of occasions as the generator has started, (it would seem like) there has been a total loss of AC output. I noticed it today when the generator started as momentarily all power was lost to the property. Speculating it could be when the Inverter moves from “inverting” “external control”.

I think the installation is fairly standard. I have four sets of solar panels on individual strings, a 15kWh BYD battery storage and the MultiPLus II 48|15000| Inverter. The generator is a 16kVa/13.2Kw Perkins P18-6. It has been with me for 5 years though it was used for the legacy system, so it has probably been in for about 8 years in total. The engine side of it has been serviced regularly. I have included a diagram of the installation.

Hi, not sure what you mean by “shore” power. However, this has never happened before. Even with my legacy lead/acid batteries using the same generator.

This is something that has occured once maybe twice in the last couple of weeks but enough to for me to have noticed it. I have provided more detail in a reply below.

Thanks for the nice picture.

Did you program warm-up and cool-down times?

What exactly did you program at Multiplus?

What firmware do you have on the MP?
