Hi all, I have recently installed a 12v Solar System in my Allotment shed & I am looking at buying an inverter to charge my cordless drill batteries & use other low wattage items at the allotment. I am looking at the inverter below. I am just unsure what Amp fuse I would need to install between the battery & the inverter? Would i be right in thinking if its a 4000W inverter would I need a 400A Fuse ? Or am I being stupid? It looks like you can plug this into a 12v car cigarette lighter socket so I am assuming it wont need a high amp fuse?
Any help / advice greatly received
