Hello,

I’m preparing to install solar power into my computing room as a method to reduce electric cost’s and as a backup in case of a power failure; I decided this as my documents we’re corrupted when our Power Supplier fed a small 100W’s into our entire household, damaging my SSD (data drive - non-mechanical).

So far I snagged up a couple of online bargains to get started such as some 12V 90AH Battery’s and Solar Panels.

I currently have:
2 x 12V 90AH Battery’s (http://www.ebay.co.uk/itm/120714732057?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_2317wt_901)

2 x 12V PV 80W Solar Panel (http://www.ebay.co.uk/itm/370577902422?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_902wt_1392)

In order to power up to a 1kW - 240V appliance, how would this need to be setup / what else do I need? I’d prefer to draw the power from the mains during daytime, and automatically switch to the solar / battery’s after sunset or a power-cut.

The power drawn won’t likely reach 1kW for more than 10 minutes, depending on the task I need computing; else it will drop to around 230W an hour.

Also how many hours of power can I get from a single day’s worth of charging, let’s saying I’m using 100W an hour? (an average of 11 hours sunlight).

If you have any advice / answers then please let me know, as I’m lost to what needs doing next.

Kind Regards,

Jordan.
