AP Systems QS1 MicroInverter

Microinverters are used in grid-tie systems.  They are mounted behind the solar modules on the rail system or on the frame itself.  DC power is converted to AC power at the module and fed into a common branch circuit trunk cable which is then fed to the household utility panel.  Converting power at the solar module allows for "per module" power management.  If a single module in an array is shadowed or compromised, it will not affect the performance of other modules in the array; a distinct advantage over traditional string inverters.

The APsystems QS1 is a quad module microinverter, meaning a single unit can accommodate four modules, reducing cost and speeding install time.  Each module is connected via independent MPPT inputs.  AP Systems boasts a wider MPPT voltage range than most competitors, meaning greater energy harvest in low light conditions.  Wireless communication reports operational data to the AP Systems Energy Communication Unit (ECU, sold separately) located in your home.
