Prostar off grid solar system 300W



Product Detail




Prostar 300W off grid solar system including 2PCS 150Wp Solar Panels, off grid solar inverter 300w and 1unit 12V 100AH deep cycle batteries.


Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. Photovoltaics convert light into an electric current using thephotovoltaic effect.


300W off grid solar system


  1. 5-6 Hours operating everyday
  2. Easy installation and maintenance
