inverter with batteries v generator

[bk81]

I fit 12v 100Ah batteries for telecoms companies. The brand we use, enersys, weigh 28kg each so you could maybe use 4 which would take up a space under 600mm x 600mm and about 150mm high.

Just incase the weight and size issue was a dealbreaker...although the cost might still be!
