POWER INVERTER CHARGERS
Experience reliability and versatility with our Wall-Mounted Pure Sine Wave Inverter Charger WI series. Ranging from 1KW to 12KW, it supports 12V, 24V, or 48V DC input. Power your world efficiently with precision in backup systems, off-grid solar systems and more.
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.

Key Features:

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.
