Inverters

Inverters


General Description

Inverters are the heart of the load shedding backup and off grid systems.

It converts DC (Direct Current, as from batteries) into AC (Alternating Current as from Eskom), so that one may continue with all the normal appliances in a household or business.

Typical inverters available are from 1000W to 10 000W.

Pure sine wave inverters are more expensive however, are also more versatile to run all appliances as per Eskom power.

Product Technical Data and Detailed Description

Inverter

High quality Pure Sine Wave Inverter 1000W~6000W solar Inverter:

  • 3 times Peak power
  • 35/70AMP built in charger.
  • 12V-24V-48VDC, 500W-8000W, UPS function

LW Series Pure Sine Wave Inverter takes high frequency converter Device. Zero Voltage(ZV) and soft switch technic, high capability Motorola MCU, digital and dummy combined technics which complete the voltage increase in one time and SPWM wave modemed Advanced circuit, high efficiency and compact size, small weight and super stability.

It is widely applied in wind generator, Solar battery pack set, house, vehicle, ship, navigation and places where lack of city power, mobile electricity work and telecommunications device, launch station, Emergency EPS.

Pure sine wave Inverters has no “repellency”  for the load, which can work well with fluorescent lamp, electromotor, microwave ovens, Induction cooker, refrigerator, air conditions and transformer.

With protection function like, DC input protect when pole wrong, AC input protection against over and low voltage, Output protection against over load, short circuit protection, DC input and AC output completely electric insulation.
