Inverters

Interesting..........

On an 18 watt tube, at .8 PFC, we need I think around 3.0 uF.

This is a hard call, as ETSA here in SA require Caps in ALL fluro fittings to balance loadings.

When we connect banks of these to the grid, without a cap, they draw way too much power, mega test goes all wrong, put in a cap, and all is good.

I have often wondered about the effects when using an inverter.

So far, I have ran an 18 watt for around 40 hrs, on a modified square wave, and it's okay, but I have yet to try on pure sine.

I ran an 18w fluoro on my 200w MSW inverter for a few trips and all was well. Then I ran a 40w fluoro on the same inverter and blew it up. Jaycar fixed it under warranty and then told me about the capacitor. It is also in their catalogue (it was 3yrs ago anyway).
