Energizer ENK2000 Power Inverter Features and Specifications
Energizer ENK2000 is a versatile, robust, and reliable power inverter suitable for various situations and uses - on the boat, in the car, RV, when camping, fishing, tailgating, in emergencies, and all other off-the-grid situations.
The unit comes with 3 feet (~0.9 m) 2 AWG cables used for connecting the inverter directly to the battery. Despite the Energizer ENK2000 coming various safety features including overload, over-voltage, under-voltage, high temperature, short circuit, and similar, it is highly recommended to install an ANL fuse as near as possible to the positive terminal of the battery.
The exact current rating of the ANL fuse should be according to the situation and expected load of the battery/inverter, but if one requires the full power of the Energizer ENK2000, the unit requires ~215 Amps @12V for 2000 watts. For surge power of 4000 watts, one needs an ANL fuse of at least 400-450 Amps - and that is a lot of current!
ANL fuse should come with a transparent fuse holder and gold/silver plated contacts - accidental short circuit of a large lead-acid battery pack may create currents in excess of 4-5000 Amps. Such current may cause wires to evaporate (almost explode), it can destroy the batteries, cause fires, injuries, or worse...
Note: Energizer ENK2000 is simple to mount and use power inverter, but when it arrives, be sure to read the manual thoroughly in order to get accustomed to your new unit - note very important requirements about mounting positions and similar.
Energizer ENK2000 Power Inverter is a rather compact unit, featuring physical dimensions of (L x W x H) of 15.39 x 6.71 x 3.46 inches (~39 x 17 x 8.8 cm) and it weighs 6.61 pounds (~3 kg).
The unit can be easily mounted in virtually any position, just be sure not to place it under the hood - too warm for such a unit that features an operating temperature of 0° - 40°C.
LCD screen displays all relevant information, including input voltage, output wattage, battery level, temperature shutdown warning, and high/low/overload voltage.
Energizer ENK2000 Power Inverter comes with a 2-year warranty period.
Energizer ENK2000 Power Inverter Battery Sizing
Energizer ENK2000 is powered from a 12V power source and that practically means a 12V battery or preferably a battery pack.
We say 'preferably' because for the unit to provide 2000W output, it requires 215 Amps @12 volts - Energizer ENK2000 maximum efficiency is 90%, but that is 'maximum' efficiency.
The input voltage range is from 10.5 to 15.5 volts, which means that most large-enough 12V batteries (or battery packs) are suitable.
For example, Renogy 12V 200Ah 4D AGM Battery is able to provide ~215 Amps, but down to 9.6 volts for 30 minutes. Or, it is able to provide ~215 Amps for 15 minutes down to 11.1 volts.
However, four such batteries connected in parallel are able to provide 200 Amps for 3 hours with the battery voltage dropping down to 10.8 volts - they can power Energizer ENK2000 Power Inverter for almost 3 hours while the unit provides its maximum output of 2000 watts.
If You are looking for suitable batteries for Energizer ENK2000 Power Inverter, consider large 4D and 8D batteries with 200Ah or more capacities.
Smaller batteries may be used as well, but a suitable battery pack would require a rather large number of such batteries, or the runtime would be rather short.
Long Story Short: Energizer ENK2000 is a heavy-duty power inverter that may be used in various off-the-grid situations. It is able to power various home appliances, ranging from smaller TVs to mid-range AC units and electric tools.
If You are looking for a modified sine wave power inverter in this class, consider this unit.
