dear all,
I am reading BP sphoto voltaic specification BP380 and found at note 1 about STC (standard Tes condition). it is said that STC is conducted in 1000 W/m2 and cell temp 25 dec C to get warranty output 75 W. Efficiency is 0.12.
If in area, the insolation is 4.5 kW/m2/day and daylight...

The scottyUK's question at 27 Jan is also question. I've tried install 1 phase ELCB (2 pole, Line-neutral), but since there is no neutral, both poles are life wire. I test the installation using 2 methods:
(1) Using trip button built in the ELCB
(2) Using ELCB tester, by connecting life wire to...

Metengr,
The boiler type is wall fired burners. I think it should have atomization device for better combution and you are right it must be difficult to find the proper location for it. I can't describe what cyclone boiler is, I don't know whether it work fine as in cyclone boiler just like Doug...
