Prepare to evaluate the current system
Buy a multimeter - A £10-15 will do.

Check the current system
Check for 10.5-15 volts supply from the current system components.
Buy new system components
Buy a 300W DC Inverter, a 700VA Uninterruptible Power Supply (UPS). This should have it's own battery), 12V DC inline Fuse Holder, 35 Amp fuse and sufficient 12V cable to connect all components.
Set up the new system
Run the cable from the panels/turbine to the fuse to the inverter+UPS. Connect the multimeter in-line in Amps-mode and connect to the inverter. Plug the Inverter into UPS. Plug all the appliances into the UPS.
Notes:
Sunlight will run up to 300 Watts via the inverter (check meter: amps x 12 volts = Watts). UPS battery will run your ADSL modem and a phone charger for few hours.
