80A/60A L80 L60 MPPT Solar Controller Key benefits Higher charging efficiency: MPPT tracking increases charging efficiency by 10 to 30 percent compared to conventional controllers, capturing more available solar power. Low standby consumption: More than 30 percent lower standby power compared to normal controllers; standby current only 10 to 15 mA. Reliable battery protection: Built in overload and short circuit protection, low voltage cutout and recovery, and reverse discharge protection to extend battery life and improve conversion efficiency. Simple operation and recovery: One key to open and close the cargo and one key to restore factory settings for quick setup and troubleshooting. Temperature aware charging: Automatic temperature compensation adjusts charging voltage by 4 mV per cell per C to match battery temperature. Main functions and performance Smart PWM compatible MPPT charge controller that supports efficient, energy saving operation while automatically tracking maximum power point. Battery float voltage: 13.8 V for 12 V systems, 27.6 V for 24 V systems. Low voltage protection: 10.6 V for 12 V systems, 21.2 V for 24 V systems.
