Opis produktu
Product Overview The FT-S1220 is a 20A PWM solar regulator engineered for off-grid photovoltaic power systems. It automatically identifies 12V or 24V battery voltage and is compatible with three mainstream battery chemistries. The unit adopts a double MOS anti-backflow design to prevent reverse current drain overnight. Users can read and adjust charging and discharging parameters via the integrated LCD panel. Key Features Multi-battery compatibility: Supports B01 Lead Acid,
