I seem to mostly work at night these days, but even during the day, I have all the lights on. With the miserable solar rebates for feeding power to the grid, and 30c per kw/hr for what I take from the grid, I've been planning to go off-grid with the workshop lighting for a year or two.
Slowly accumulating batteries and solar panels, I've finally made a start on getting it all together.
One missing component was the enclosure, but I lucked out on a Grays' Auction and got a decent size enclosure for a reasonable price.

The last few days Josh and I have welded up a battery frame to take the 120AH deep cycle batteries, I got them from a job where they are cycled out of use after 4 years, but they should still have another 5 or 6 years of life, if looked after.
The inverter, takes 50V solar in, 240V AC in, 24V DC in and provides 240V AC out, and charges the batteries from either Solar or mains, so in the event of insufficient solar the batteries are maintained from the mains input. A bit like a big UPS. Maximum power out is 2.4kW, Workshop and outside lighting are less than that, and I will run 240V power to the server rack and NBN cabinet so that servers and lighting stay up over a power outage.

The Solar come from 3 x 250 W 50V panels, not yet connected. ( or mounted for that matter :) )
The lighting is a mix of LED tubes and 100W led modules.
More updates when I get some panels hooked in and the proper circuit breakers and isolation switches arrive.
