Have a question which I tried to research but no exact answers so far, so wanted to brainstorm it with you folks here first.
The customer is somewhere up in the mountains and has regular outages in winter time, which is upcoming. Hence he wants us to integrate a generator with the sistem.
Current setup:
3 x 5KVA MultiPLus 3P system
15kw LIFEPO4 storage
20A grid input
Attention: ESS is in operation, when network is up he can inject and inverters are setup with Romania Grid Code
Question is how would you integrate a generator here? Is it even recommended or possible given the grid code on AC in? Also if you have, recommend a model generator.
The challenge is that with a single input the multi isn’t suited for differentiating between settings to make a gennie happy and grid, which can mean manual changes.
Quattros are way better in this application.
In the case of 3-phase generator operation, the grid code and grid acceptance would have to be changed. This is not for a normal end customer.
Quattros would have to be used here, but this would probably be cancelled due to the price.
It’s best to stay on the DC side for charging. And 15kw is not to much
On the subject of charging via Eltek / Huawai on the 48V side with a single-phase generator … these are already available quite cheaply with gas
Alternatively, of course, via 3-phase …
Very good point. Was thinking to put an ATS with grid on one side and generator on other. Feed-in of course doesn’t matter when running on generator. If the Multi would just let that electricity through. Unfortunately Quattros are out of question because this is an existing system.
Guess the only option then is to run the AC OUT thorugh an ATS along with the genset and when Multis go down, the genset to take over.
