I have read the other thread 'Best way to power Christmas lights without nearby outlet' and my question does differ.
We have a Christmas Tree which sits in the middle of our Village Green every year. The lights need to be on from about 4pm until midnight every day for almost a month. Until now, we have used multiple threads of battery powered Christmas lights (AA/AAA) but the results are not very good, with the lights being very dim.
We would now like to power normal (mains) bright LED Christmas Lights by some means. We have explored all options of connecting to a mains supply and they are prohibitively expensive. The current thinking is that we should use some sort of car battery. (Using a generator has been ruled out as being too noisy).
My question is what specification of car battery would we need to get to power about 600 lights for a month, hopefully without having to charge the battery too often. Is this even possible?
We have not yet purchased the lights, so we could buy ones that suit the battery. I appreciate from the other thread, we may need an inverter. The question in the previous thread related to powering lights for only a couple of hours, so this is a very different scenario. Also they already had the lights they wanted to use, whereas we can choose lights to suit the battery.
Thank you in advance for any help.
