Thank you very much guys.
Actually the inverter meets al the UL 1741 requirements and will shut down in case the grid is down. So nobody will die:-). We are safe on that side. I do know something about a 6kW imbalance rule for 240V systems. But it seems that this doesn't apply for 208V / 277V...
Hello,
well first of all thanks for all your inputs.
It is really very helpful and give new ideas.
Does anyone know some rules eg. UL / NEC, in regards to this? Is there some kind of Code Standard or other restrictions?
Thanks,
Norbert
Hi ppaya,
thanks for your answer. Well, 4KVA seems pretty low because a single heater has 3 kW. Nevertheless, when I do the calculation, I do have a 200 Amps Panel times 120V- I am at 24kVA.
So 4 KVA seems pretty low.
Any other ideas?
Thanks,
Norbert
Hello Guys,
thanks a lot for your answers.
Unfortunately, there is no real chance to get such a 3phase 12 kW inverter. Nevertheless, I want to use hte single phase because it is much more easier to connect and handle the whole installation.
I am still unsure if I can do it?
Any Code issues...
Hello,
I do have an very tricky question where I want to get a better understanding of.
I am an electrical engineer and want to install Solarinverters on my house. I do have a three phase 208V system and I have to feed in between the phases. How much of imbalance load is allowed?
Can I...
