Greetings everyone;
I have been seeing a lot of companies lately been advertising 5KW systems installed for $2200. Be warned these systems are not 5kw. It is a 5kw inverter and most of the time there is only a 1.5kw or 2kw worth of panels. This becomes a problem because later if you want to install more panels you should match the panel size and watts with excisting panels.
So for example if you have 10 x 190 watt panels (it isn't adviseable) to install more panels that are 250 watts. Also every panel has different amps and voltage, this also should be matched to the excisting panels. if they don't it can cause your inverter to blow up..
