HI, I want to use a pure sinewave inverter, can you you guys explain the do's and don't s with inverters. Also what effect fluro's have on inverters.

Why do you want a pure, over a modified, or square wave?

What is your prime reason for having this thing?

I use fluro's on ALL of my inverters, and I have had no problems at all.

Just remember, the inverter is putting out 240 volts, which if it doesn't kill ya, can quickly change yours, or someone else's day if you're not careful.

The effect that fluoros have on inverters is they can blow the inverter up. However if you open the fluoro up and remove the capacitor (there is only one) then all will be ok.

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).
