I read a thread on another site where an individual had multiple problems with a Longevity unit (don't know which one) and it ended up with he was feeding it 250 volts. Unit is spec'ed for 220 (+/- 10%) (198-242v). Before I ordered, I talked to Simon about the fact that the US power grid is closer to 240 volts than 220 volts and from his response I understood him to say that they had put a limiter on the units now to protect them and that there should not be a problem. As I have unpacked my unit and put in the 50 amp circuit I noticed as I was checking it that my power company has a very stable 246 volts on the supply line a small amount above the upper limit of the %. Talked to John in tech support this PM and he was not real helpful in clearing up the issue as he did not even know what voltage they have from the California utility but kept saying the unit is a 220 volt unit clearly indicated on the web site.
I would not even bat an eye at this except for the other posting about 250 volts hurting this other Longevity unit.
For those of you with Longevity units what voltage are you getting out of your utility companies and have you had any problems? I have left two messages and have not heard back from Simon just from John which I already described.
