pond electrics....?

[dysons12]

Hi guys
i had an idea of using a solar panel to charge 2 12v batteries at 7(amph) small i know....that would power an outdoor pond. Which i have started to build but i wanted a more powerful pump so i bought a 12v to 240v inverter which can run upto 400w? Now the pump i have is 240v and 230w 50hz when i connect to battery it just buzz's but doesent power at all?

Is this because the battery is not good enough or what???

And secondly....

If i wanted to use 2 batteries is there a product or something i can make so that in daylight hours it runs of 1 battery whilst the other is being charged by the solar panel whilst the other is used to power the pump and vice versa when that runs dead...


really bugging me this is.....

ideas/knowledge and or experience would be gratefully appreciated


thankyou,

Michael

as for the gas thingy ventilation, just stick a dyson on it.

question is irrelevant anyway as no matter how large the chimney is, it would be totally useless when blocked by father christmas's fat arse.

yup agree, but not with a solar powered pump though lol, unless you have a garden full of them and next door lets you put panels in their garden as well.

on the subject of free power.....I just had a chinese company, offer me hamster wheels, which are usb chargers. as the hamster runs on the wheel it charges your phone.....this i kid you not...couldn`t believe it when i got the email.

epic! I'd love to see that pitch on dragons den...

only in China.......just sorry i didnt think of it first...they even stated that this is a natural function of a hamster, and doesn`t constitute animal cruelty
maybe the op should get a few hundred of these to power his pond

You may laugh but my 11,000 hamster 8 Kva geny works a treat....although they need a good drink of water after stick welding 3.25's for an hour...to the OP,this idea sounds like the argument i had with me mate at the age of 15...he could not understand why a DC generator coupled to a DC motor would'nt run constantly after an initial spin...there is ALWAYS a price to pay for step changes in energy type change. Set up a wind driven simple pump that gravity filters through decreasing granular media... or maybe a steroid-fuelled hamster on a stirrup pump
