solar question

 Hi all looking for some advice.....

I have 4 solar panels that were given to me and apparently are approx 150-2
50 watt each.  I want to use 1 or 2 panel to run small lights and radio (an
d small tv maybe??) in greenhouse.  I have leisure batteries but was confus
ed which charge controller to get?  Would I need an inverter too?

Thanks in advance for any help
