NE means (Non-electric). This does not mean that is is not powered but that WCT system only has a D/C fan unit for ventilation.
240 means (240 volts A/C). This means the system requires alternating current (A/C) common to mains-power and most of these systems are heated, therefore a micro power plant such as solar or wind will most likely not generate enough power. It is also considered a bad practice to use solar or wind energy for heating.
