I'm guessing that inverters dont have the ampage to run lights ?

no, that inverter is a 2kw inverter, so you could run 2kw (2000watts) of lighting from it. but it doesn't supply the power, it just converts voltage.
power is kilowatts, and (in basic terms) is voltage times amps. so from a 12v battery you need 12v x 166.66A to supply 2kw. a car battery for instance can supply 166.66A and is 12volts. and is generally where these inverters are used, for supplying AC mains power in cars/vans/caravans etc
to supply 2kw at 240v you need 8.3A, 240 x 8.3 = 2000. all the inverter does is take the high amp low voltage power fromfor instance a car battery, and turn it into high voltage low amp power to run equipment designed to be powered from mains voltage. the inverter isn't a magic power supply, it's just a box for converting DC electric into AC mains power, because different items of equipment are designed to run on different types of power
so for our 2kw of lighting, we'll need 166.66 Amps from our solar panels..... which is a lot of solar panels
