Renogy 2000W 12V Pure Sine Wave Inverter
Renogy 2000W 12V Pure Sine Wave Inverter features 2000W continuous and 4000W surge power and is powered by 12V batteries - the inverter supports the use of various lead-acid and lithium batteries.
The unit features physical dimensions of 17.8 x 8.6 x 4 inches (~45.2 x 21.8 x 10.2 cm), and it weighs 11.7 pounds (~5.3 kg).
Renogy 2000W 12V Pure Sine Wave Inverter safety features include LED indicators for under-voltage (alarm @10.5V±0.5V, shutdown @10.0V±0.5V) and over-voltage protection (shutdown @16.5V±0.5V), over-temperature protection, over-load protection, and short circuit indication. Also, the inverter comes with ground-fault circuit interrupter (GFCI) protection.
The unit is also very energy efficient, with an efficiency of >90%. Nonetheless, two cooling fans are available to keep the internal temperature at acceptable levels - cooling fans are thermally controlled, saving electricity and improving energy efficiency even more.
Renogy 2000W 12V Pure Sine Wave Inverter comes with three 120V AC outlets, one AC Terminal Block, and one 5V/2.1A USB charging port.
Also, it comes with a pair of 3 feet (~0.9m) long 4 AWG battery wires (red and black), and 19.8 feet (~6m) remote controller, allowing the user to mount the inverter near the batteries and to control it remotely.
Renogy 2000W 12V Pure Sine Wave Inverter is advertised as a pure sine wave power inverter - the unit features Total Harmonic Distortion (THD) of <3% when powering linear loads and <5% when powering non-linear loads.
Such THD levels allow the Renogy 2000W 12V Pure Sine Wave Inverter to be used even for powering sensitive loads.
Renogy 2000W 12V Pure Sine Wave Inverter comes with a 1-year limited warranty.
Battery Selection for Renogy 2000W 12V Pure Sine Wave Inverter
Since it features continuous output power of 2000W and surge power of 4000W, Renogy 2000W 12V Pure Sine Wave Inverter requires:
PBattCont = 2000W / 12V / 0.90 = ~185 Amps
PBattSurge = 4000W / 12V /0.90 = ~370 Amps
So, during continuous operation, the maximum current draw is 185A, and during maximum allowed surges, the maximum allowed current draw is 370 Amps.
Note: these are values calculated @12V. When the voltage drops below 12V, the unit will draw even more current in order to compensate for a voltage drop.
So, for powering Renogy 2000W 12V Pure Sine Wave Inverter without overloading the battery, one should go for a 12V 200Ah (or larger) lead-acid or lithium deep cycle battery, just note:
Lead-acid batteries feature strong capacity loss when being discharged with 0.5-1.0C currents, but they are very reliable when there is a danger of power surges. Also, they are cheaper but tolerate a smaller number of charging/discharging cycles, may be charged with 0.10-0.15C currents, and are much heavier.
Lithium batteries are practically almost exclusively Lithium Iron Phosphate (LiFePO4) batteries, they are very light, tolerate a huge number of charging/discharging cycles, can be charged with currents up to 1.0C, etc. However, lithium batteries come with Battery Management Systems (BMSs), which monitor the battery's parameters, and if required, they disconnect the battery in the case of unwanted events.
With an average continuous discharging current of 1.0C and surge current of 2.0C for 2-5 seconds, one needs at least a 12V 200Ah lithium battery to power Renogy a 2000W 12V Pure Sine Wave Inverter with no issues with the battery's BMS.
Long Story Short: If You are looking for a robust and reliable 2000W power inverter with excellent energy efficiency, consider this model - it also comes with a long list of safety features, quiet operation, low THD%, etc.
