Hi all, Iím new here just like to introduce myself and maybe get some advice.

We have a 4kw system installed consisting of 16 Intenergy INE-250MB-60 Solar Panels made by Perlight Solar Co, 6 facing South on the roof and 4 facing East and another 6 mounted on the garage roof that also faces South but at a shallower angle.  The Inverter is a Goodwe GW3648D-ES Hybrid, we also have a bank of 4 Hoppecke 12V 133Ah Lead Acid batteries wired in series for 48V.

So far loving the system, it is grid tied, so for a change SSE give us some money, my question is as follows. If the grid goes down as it did recently, the whole solar system goes down.  Now I believe this inverter can be used grid tied or off grid, How can I get the system to work off grid if I were to turn OFF the AC supply (and the only way I can think of is yanking out the main fuse, which would annoy the electric company no end), I want to now try see how long I could actually last without being connected to the Grid

Many thanks
Dave

Hi Dave and welcome,

I would say 'when wll else fails' RTFM http://anro-developments.co.uk/wp-content/uploads/2015/06/Goodwe-ES-Manual.pdf  hysteria  hysteria  hysteria Page 18 says it can be done whether it's actually legal or not connecting that inverter to the grid is another matter though.

Good luck, Paul

Hi Paul and thanks :-)

Funnily enough over night i stumbled on the way to actually get into the setup of the system so i now know how to change work modes, it is all grid connected anyway by a company called Solar Studio, but they are another whole different story and by the time the whole system was operational (which took over a month), i knew more about the Goodwe hybrid inverter than the guys fitting it lol although in my opinion the manual is still very light on knowledge, especially for people who like to play around :-)
