Solar Inverter (off grid) MPPT controller

Short Description:


Product Detail

Product Tags

· ST inverter efficiency is more than 85%
· New design, adapt to wide and narrow voltage, automatically recognize frequency
· Full LED display, inverter function can be selected according to customer's use
· 3 working modes are available: mains priority, inverter priority, energy saving mode
· More than 3 times the peak starting power, excellent load capacity
· Smart fan (automatically adjust fan speed according to internal temperature)
· Power frequency technology, pure sine wave AC output, adapt to load capacity, no-load current is smaller, more energy-saving
· Built-in AC 3-stage charging module, which can automatically adjust the charging current according to batterycapacity and actual use (5A-30A)
· It has complete battery undervoltage, overload, short circuit protection and other comprehensive protection, safe and reliable1
