Extra 4kW of PV for stand alone system.
New install of an extra 4kW of solar to an exisiting stand alone system. Solar is fed into a Fronius Primo 4 solar inverter and then AC coupled to a Selectronic SP Pro inverter for house power and battery charging.
16x Trina 270W modules.
2kW grid connect solar system has an extra 1kW added. The simple AC architecture of the Enphase micro inverter system makes it very simple to add extra capacity to an exisiting system. Because of the comprehensive display that comes with the Enphase system the client was able to easily see that an extra 1kW of solar would cover their increased power needs.
