- Brief Introduction
Sunfine SMS series are genuine on-off grid All-in-one inverters. Not like SMA (Germany) on-off grid inverters which contain one on-grid and one off grid inverter, Sunfine SMS series only have one inverter which achieves on &off grid function with auto switching. This is a great technical breakthrough,
Sunfine SMS series inverters are high frequency inverters, integrated with controlling, charging and inverting functions which are managed by one DSP. There are two times accurate MPPT (DC/DC, DC/AC) with efficiency up to 99%. All these lead to high efficiency of SMS series.

Working Theory
When the grid is normal, SMS inverter works at on-grid mode, while the grid is abnormal, SMS inverter will Zero switch to off-grid mode automatically. In the on-grid mode, SMS series inverter converts the PV power to AC for loads, and extra AC to feed grid. In off grid mode, PV power converts the PV power to AC for loads, and extra AC to charge battery. -
