We were hit by lightning on the 6th january, it hit the proven wind turbine, the outback inverter has blown, and the top has blown off one of the 2v battery cells, leaving bits of plastic casing all over the solar shed.
Stranglely the batteries are behaving fine, even the open cell, it just needs topping up all the time.
I was hoping to get another year out of my elderly batteries but this is probably the final straw for them.
I may keep 6 of them for a 12v set up.
I urge other off grid folk to aquire a spare inverter as having full batteries and no way to convert to mains is a pain.
We have had many close lightning strikes over the years but this one left us in the dark.

Sorry to hear Dave,
                But on the positive side,nobody was injured so that,s a good thing.We had a lightening strike a few years ago which blew the large blue socket in the geni,knocked out one of the brains in the symmetra rm (100 to replace s/h) and the sound on our big flatscreen went missing for a few hours.The turbine got fried.I watched blue lights flickering along the tail and lump.We were up and running the following day.The symmetra rm was able to work away untill the replacement brain was installed,(60 seconds).The big blue socket on the geni was the hardest thing to find. Grin.Fortunatly,our battery bank seemed fine,if not improved.

Exactly the same thing happened to my mate on Rona about 8 years ago Dave. The Proven got hit, took out his Trace SW4548e and blew the bottom out of one of his forklift cells. Pretty sure the insurance paid up for it and the Proven was OK.

The proven is OK, still churning, the post for the phone line is about 20 foot away from turbine tower, the phone line has needed 200m replacing.
I am not sure if it was a direct hit or just a great deal of static, it was very loud.
I suspect the open cell has a split in the casing further down from the top, as it needs filling everyday, with the weather up here for the last few weeks, I have pretty much just left it, as is.

I managed to pick up a victron pheonix 24/3000 off everyones favorite auction site the other day, new unused, we have power,  Grin, the inverter is nice and quiet, no buzzing, with the ability to stack another for more power.
I may try to find an equally duff cell to replace the broken one, I know it is not best practice but as they are all knackered, I don't think I have much to lose.

Remember lightning does strike the same place ... again and again... So erect a lightning strike pole nearby.

We have a nearby telegraph pole within 20 foot, it has a tiny little 1.5mm conductor running down it.
The proven on the other hand is made of steel and bolted to a block of concrete in the earth.
I think it is just bad luck, we have had some close ones over the years, when we were on dial up we used to replace the modem twice a year.

What about one of these on the 3 phase from the turbine to the inverter?

http://www.ebay.co.uk/itm/AC-420V-80KA-Imax-40KA-3P-Din-Rail-Mount-Surge-Protection-Device-Arrester-/290931842125?pt=UK_Sound_Vision_Other&hash=item43bce39c4d

OK, I know it's a cheapo, not much more than a pair of lucky underpants, and cheaper than an inverter  Smiley

No guarantees it will work though  Wink

 - Branded ones available in the UK for 150 quid or so.

Thanks for that, I may invest in one of those.
I did wonder why the 100a contactor in the controller did not throw.
I am also looking for some luckier shreddies than the ones I am wearing.
