Solar for a school farm

[gucu]

Hi All

I am starting to develop a farm for a school in Cornwall, UK. It will be small but will be power to run irrigation for a polytunnel. I have found a pump that is 36v DC and 2.5 amps DC with recommendation for 2 x 60w panels. However, we will also need to use sound equipment for lessons and charging tools etc. The wind equipment needs 140 watts per channel for the speakers and sound desk at 240v. I have never wired a system and sunder whether it is simpler to purchase a kit from Sun Store in the UK or is this something that could be managed.

Thanks

Rich

Yikes! Not wanting to sound rude, but in view of the target users, the "Health and Safety at Work Act" and your lack of experience, I'd strongly suggest that you employ a Part-P qualified sparky to set up any system that drives 240V equipment.

Attempting even to use commercially available off-the-shelf inverters can be fraught with risks unless you have a thorough knowledge of BS7671, grounding, RCBs etc.
