PRAG H-Series Pure Sine Wave Inverter / Charger

PRAG H-Series Pure Sine Wave Inverter is a combination of an inverter, battery charger and AC auto-transfer switch into one complete system with a peak conversion efficiency of 88%.

It is packed with unique features and it is one of the most advanced inverter/chargers in the market today.

It features power factor correction, sophisticated multi-stage charging and pure sine wave output with unprecedentedly high surge capability to meet demanding power needs of inductive loads without endangering the equipment.

PRAG H-Series Inverter is equipped with a powerful charger of up to110Amps (depending on model). The overload capacity is 300% of continuous output for up to 20 seconds to reliably support tools and equipment longer.


  • Easy to Install & Easy to Operate & Easy to Solve
  • Designed to Operate under Harsh Environment
  • DC Start & Automatic Self-Diagnostic Function
  • Powerful Charge Rate Up to 120Amp (depending on model), Selectable From 0%-100%
  • High Efficiency Design & “Power Saving Mode” to Conserve Energy
  • 8 pre Set Battery Type Selector plus De-sulphation for Totally Flat Batteries
  • 4-step Intelligent Battery Charging, PFC (Power Factor Correction) for Charger
  • 8 ms Typical Transfer Time Between Utility & Battery, Guarantees Power Continuity
  • 15s Delay Before Transfer when AC Resumes, Protection for Load when Used with Generator
  • Battery DOD(Depth of Discharge) setting from 50% to 100%.
  • SNMP remote monitoring (available as an option)
