Body

Andreas,
Yes mate, I love the NiFe batteries and I had a lot of experience servicing and looking after them in the Navy.  We used them everywhere for emergency lighting.  They are so robust and can take a lot of abuse in over charging and non charging for long periods etc.  They are said to be able to last 100 years.
Thanks for your advice mate.
George

Hi George,

Thanks for the advice mate.  I have 2 of these 15 kw 3 phase inverters in parallel and I'm looking to get off the grid altogether.  I don't want to switch back to the grid.  I have 24 kws of solar panels, 96 panels in all and I have a couple of generators and I want to get a battery bank etc.

I would recommend a bank of NiFes, e.g.
 http://www.taihangbatteries.com/products/nickel-iron-battery/tn/tn200-2.html
40 x 1.2V will get you a reliable 48V bank. 24kW is a lot. If we only knew a means to store hydrogen efficiently. Hard to get Li-6 hydride ... Any other ideas?
