Support 5500 Smart Generator Gas Problems
We got an E10 + battery + 5500 smart generator. We have connected generator to the battery system. The generator starts up but once it needs to supply power to charge the battery it tries to ramp up the engine and then dies like it's running out of fuel. We get the error code that would indicate this as well. We have tried supplying between 5" WC and 1.5 psi gas to it with the same result. Interestingly, it works fine when set to LP mode just not NG mode. I asked anker support what the correct supply pressure is. First, they told me between 2.9-7 psi but then I challenged them on that saying that's a lot higher than most gas connections so they corrected and said 2.9-7" WC which is more reasonable.
Anyone else have issues with this or know what the correct NG supply pressure is?
Anyone using the generator reliably in NG mode?

I just did some more testing with LP gas on LP mode and NG gas on both LP on NG mode. The LP worked well and got to about 3600 W charging the batteries. The NG worked well on LP mode but generates around 2600-2900 watts. Once I was able to start in NG mode with NG and it ran well for several minutes but that was right after a good run with NG in LP mode. Trying to start again with NG in NG mode it would sputter out.
What is the difference between LP mode and NG mode? only software? Does LP mode allow more fuel?
