What is an inverter? It's a device which converts battery output (DC, or direct current) into 240V AC mains electricity (alternating current). 240V AC is the type of electricity supplied by utility companies to run standard domestic appliances like TV, fridge, radio, lights or to charge a laptop / mobile phone etc. So if you have a battery, connect a power inverter to it and you'll be able to power household appliances in areas without access to mains electricity, such as in a motorhome, caravan, boat, farm or any remote locations. Inverters are also perfect for off-grid and back up systems for accidental power cuts.

What is a low-frequency inverter? Low-frequency inverters have a few advantages over inverters with higher frequencies, namely their peak power capacity and their reliability. Low-frequency inverters can operate at the peak power level which is up to 300% of their nominal power level for several seconds, while high-frequency inverters can operate at 200% power level for a small fraction of a second. Low frequency inverters operate using transformers (as opposed to electronic components such as MOSFETs for high frequency inverters): this results in a stronger, sturdier inverter which is less prone to damage. If you would like to know more about low frequency inverters please check our article Introduction to low frequency inverters.

This 6000W 24V low frequency pure sine wave power inverter comes with the following important features:

  •  A fast built-in battery charger (with charging current options ranging from 14A to 70A) to charge your batteries from mains, with advanced 4-step progressive charging and several battery types to choose from. If required, the battery charger can be permanently switched off.
  • Option to select either DC or AC priority mode. In AC priority mode, if the inverter is connected to the mains, batteries will be constantly charged by mains power (until fully charged). Appliances will also be powered by mains by default. In DC priority mode, appliances will always be powered by the batteries, even if the mains input is connected. Once the battery charge drops below a certain threshold, mains input will automatically kick-in to charge batteries and power appliances.
  • Power saving mode which allows the inverter to work in "power on demand" standby mode by only generating power when load is connected (saves energy and battery power)
  • UPS (Uninterrupted Power Supply) system which provides constant power for your appliances when the inverter is working in AC (mains) mode and mains power supply shuts down (the inverter will automatically switch to the battery and your appliances will not switch off)
  • Bypass mode when the mains power is connected (in AC priority mode). In this mode, the AC mains input is automatically linked to AC output of the inverter, therefore bypassing the DC-to-AC energy converting circuits of the unit, increasing the efficiency and making the quality of the AC output the same as AC input.
  • Detailed LCD display which shows voltages, battery status, current operating mode and other information
  • Ability to accept input AC power from a generator (recommended nominal power of the generator is twice the rated power of the inverter)
  • Various settings allow the user to customise the inverter (output voltage, output frequency, input voltage thresholds, battery type and capacity)

 

6000W nominal power and 18000W peak power mean that this inverter is suitable for all standard household appliances including kitchen appliances (such as a fridge, microwave, TV, power tools, vacuum cleaner, cooker, oven, dishwasher, washing machine, air conditioner etc).

This inverter comes with important protection and safety features, such as overload, over-temperature, low battery and overcharge protection.

The product is covered by a 1 year manufacturer warranty. For more information please refer to our Terms and Conditions.

 

The inverter comes with a detailed user manual which explains wiring, installation and operations.

Please note that this inverter has AC power screw terminals instead of mains power sockets, so it can be connected to one or several AC mains power sockets by using suitable AC cables. In the UK 3-pin UK stype mains sockets can be used, and in Europe it can be connected to standard European mains sockets.

Also note that this inverter does not come with any cables. Detailed recommendations for cable length and thickness are available in the user manual.
