10kw off grid solar system for a whole house 

 

Off grid solar system , also called stand alone solar system, solar power system. 

 

solar panel --- controller --- battery bank --- off grid inverter --- AC loads .

 

when sunny days, solar panel produce electricity, then flow through controller, battery.  inverter take electricity for AC loads. Excess electricity will be storage in battery. when no sun ( bad weather ), off grid inverter take electricity from battery for AC loads.

 

 

Meanwhile, off grid inverter can connect state grid for back-up. that means, if bad weather last so long that low battery, off grid inverter auto transfer to state grid to take electricity for AC loads.

 

 

10kw  off grid solar system  configuration :

 

 

Off grid solar power system components :

 

solar panel : monocrystaline silicon cells, 10years output 90% & 25years output 80% of its nominal power rating

Solar controller : PWM or Mppt solar charge controller (Optional)

Battery : fully sufficienct capacity. AGM lead acid battery (5-7years lifespan), GEL battery ( 7-10years lifespan)

Off grid inverter : isolated transformer inside, better stability than transformerless type. Meanwhile, off grid inverter with AC input for back-up .
