Without me reading through all the user manuals.If someone knows off hand. What is the main difference between the lite and the standard version. As in what am I giving up if I get the lite?

The Lite doesn't have the serial port so logging to a PC isn't possible. The accuracy appears to be the same. They also mention that the "others" (not the Lite) can handle inrush loads up to 15A briefly.offgridQLD wrote: Personally I don't see myself wanting to accurately measure any single AC plug in loads over 2400w. It was more if I Was sacrificing accuracy or key features with a lite.Kurt

The change from 4.7A (batteries charging with bypass) to 3.4A (batteries not charging with bypass) suggests the mains battery charger in the unit has a reasonable power factor (4.7-3.4=1.3A~ for a one to two hundred watts of batt charging).
So if bypass just switches the mains direct to the resistive load of the 60w lamp what else is in there to draw the 3.4A of out-of-phase current? When bypass is off the mains current drops to 0.1A~ which also seems reasonable for 2 boxes in stdby.

Aren't I, though?weber wrote: That's all very interesting, Coulomb,
Excellent point, and my bad. I was confused when you correctly mentioned the inductor on the output of the inverter, and I switched to the inductor I'm familar with.but I think completely irrelevant because the PIP is not acting as an inverter in what is being discussed -- only as a charger.

I assumed the same, and still do.... I've been assuming that charger is essentially the inverter, operating in an unusual mode where only the lower pair of IGBTs is switched.
But I would think that a filter inductor would be pretty small (less than 1 mH, say), so its reactance at 50 Hz would be quite small (well under an ohm). I would not expect this to cause such a low power factor.

I've experienced one of the zaps, and it's not pleasant. But Weber claims that there is a pre-charge circuit in the PIP, just that it doesn't operate if the battery has only recently been disconnected. He says he's had many connects where there was no splat at all.offgridQLD wrote: I need to come up with some kind of precharge arrangement (To avoid the zap when the PIP's caps charge initially) for the PIP4048 as I need to disconnect it regularly at the 120A Anderson and remove the PIP4048 and battery separately.
