Product Details

Though the cost of an inverter is less than 15% of the total amount in a power system, without it, the whole system doesn't work. An Inverter is one of the most important pieces of equipment in power systems including solar power systems and UPS backup systems. It's a device that converts direct current(DC) electricity to alternating current(AC) electricity for most home appliances use.

The WI series power inverters output a pure sine wave similar to the waveform of the grid power. In a pure sine wave, the voltage rises and falls in a smooth fashion with very low harmonic distortion and cleaner utility-like power. This gives users stable enough power to operate tools, air conditioners, fans, lights, computers, and other electronics without any interference. Pure sine wave inverters are in many cases more efficient, allowing users to use less energy and allow for more device capability. The main advantage of pure sine wave inverters is that they are used to operate sensitive electronic devices that require high quality waveform with little harmonic distortion. Almost every electronic device could be powered using a pure sine wave inverter.

How It Works

How the Off-Grid Inverter System Works

Solar energy is managed by the MPPT controller to charge the battery bank. The inverter converts stored DC energy into stable AC power for connected loads.

  1. Solar Panels
    Generate DC solar energy
  2. MPPT Controller
    Optimizes charging from the PV array
  3. Battery Bank
    Stores energy for later use
  4. AC Loads
    Receive converted AC power
Utility / Generator
Optional backup input, subject to final configuration
