Batteries and panels both increase peak powerFour Simplicity batteries and 50-60 panels each provide 16kW of peak power (100A 120/240 VAC panel), enough for an average house. These same batteries also store 24 kWh of energy, the amount the house uses in a day.  Add more batteries and inverters as needed.    
Start with some solar panels and an off-grid inverterWIth a dozen panels and a Simplicity offgrid inverter, you can power about 3000 watts of appliances when the sun is shining. More panels means that you have higher power. To power the inverter at its peak 16 kW only from solar power, you’d need about 60 panels and full sunshine.  
Use the grid as a backup If you have limited space for panels or a shortage of bright sunlight, you can supplement the solar with a small grid charger.  With four batteries, a 1kW generator or grid charger can accumulate enough power for an average house all day and night.
Totally renewable, energy independenceFor less than $30,000, an average home can be iimmune from grid outages, oil and gas price increases and unforeseen weather events.  In addition to the security of independent solar power, the zero net energy solar home can be built wherever you can build, not just where the power company delivers.
Two modules — infinite possibilitiesSimplicity is two components, a 16 kW off-grid inverter ($2,950), and a smart, power-controlled battery ($3,950) that supplies 4 kW of power to the inverter and can store 6 kWh of energy to use whenever it’s needed.  These two components can be mixed and matched in thousands of configurations. Plug in as much power or as much energy storage as you need, any time you need. 
Or just add batteries to handle the peak demandIf you add batteries you won’t need as many panels because the batteries store the power to handle peak loads and provide power day and night.  Most homes have a peak power need equal to about three to five times their average power consumption.
