I have just had a solar panel installed, only to discover this only charges 12v meaning I can't use the plug sockets without being connected to mains electricity as they operate at 240v. I know vaguely that an inverter may solve this problem, but don't know anything about this. Can anyone advise me? My solar panel is 95v and we don't currently use a TV. Sockets are useful for charging our mobiles, ipad, using hairdryer erc
