6KVA 48V Pure Sine Wave Inverter /Charger CF6050S

Fast Charging Pure Sine Wave Inverter with RCC Remote Control

Description – Overview

PRAG 6KVA-48V ADV Inverter is an inverter/charger combination with high reliability providing true sine-wave inverter, lead acid battery charger and AC transfer switch together. It can be connected to either solar, grid or generator to compose power system for the most demanding power backup application.

PRAG Energier Pro was the bi-directional inverter designed for advanced solar hybrid system. Energier Pro delivers high reliability, performance and industry leading efficiency for mission critical application. In areas where the grid was limited or unreliable, where diesel generators are still being heavily relied on, Energier Pro will be a perfect choice to compose hybrid power solution.

PRAG Energier Pro integrated multiple functions, including a powerful battery charger, true sine wave inverter and a high speed automatic transfer switch. Its distinguishing surge capability makes it capable to power most demanding appliances, such as air conditioner, water pump, washing machine, freezer etc.

With built in AEA, it can automatically allocate the power available with AC source (either grid or genset) using whatever extra to charging, thus avoiding grid or generator to be overloaded. Through TAI, it is capable of handling two independent AC sources which could automatically switch between active grid and diesel generators
