There are many suitable 4,000W inverters on the market right now, and this post will help you narrow your search.
If you are looking for a 4000W inverter, then you are probably looking for an inverter to power your off-grid cabin, larger boat, or RV. If this is the case, you probably want to include more sensitive appliances and electronics.
I’m going to assume this is probably the case and focus on pure sine inverters. So first, I’ll review some of the basic functionality and then provide you with the options.
Let me briefly explain the different types of inverters and how to narrow down your choices.
There are two main output waveforms for Power Inverters – the modified sine wave inverter and the pure sine wave inverters.
Below are two of the market’s most popular modified sine wave inverters.
Kreiger makes one of the most popular modified inverters on the market right now, and they back their inverters with 3-Year parts and a labor warranty.
This inverter is easy to wire and use and provides a wired remote control which is very convenient when the inverter is tucked away. In addition, the inverter offers 8,000 watts of peak power and numerous safety features.
Features: 2x 110 AC outlets, 2xUSB Outlets, Quiet Fan, 3′ battery cables, Dimensions: 15.5 x 7.62 x 5.5 inches, Weight: 11.4 pounds, ANL inline Fuse, Built-in hardwired kit for applications larger than 15 Amps, Safety Protections (Overload, over-voltage, under-voltage, high temperature, and short circuit), ETL Approved Under UL STD 458
The energizer brand is well-known and has a good reputation. The Energizer 4000-watt inverter is one of the most popular modified sine wave inverters currently available online. We have listed its features for you to make your decision easier.
The Energizer offers 2-Year parts and labor warranty which is still very good for its category. It also has a wired remote, but in the case of the Energizer, it will need to be purchased separately.
Features: 2×110 AC outlets, 2xUSB Outlets, 8,000W Surge, ired remote is purchased separately, Quiet Fan, 3′ battery cables, Dimensions: 15.2 x 7.6 x 5.5 inches, Weight: 11.5 pounds, Safety Protections, (Overload, over-voltage, under-voltage, high temperature, and short circuit), Hardwire Kit, ETL Approved Under UL STD 458
There are two types of pure sine wave inverters. The low-frequency (LF) pure sine wave inverters and the high-frequency (HF) pure sine wave inverters.
The LF inverters use a big copper transformer, which is more extensive, heavier, and expensive. Therefore, they are also better with high starting power equipment, such as compressors and air-conditioners, mainly if you use them regularly and for long periods.
The HF inverters use smaller transformers and electronic components. As a result, they are lighter in weight and are less expensive. As a result, these inverters are suitable for electronic equipment and smaller devices when using them for several hours daily.
The three 12-volt inverters below have good reputations and very good feedback. They also provide the features I look for when purchasing an inverter.
This low-frequency inverter is a beast and a choice for a few reasons. First, AIMS is located in Nevada, has been in business for over 20 years, and offers a good warranty and technical support. Second, inverter manufacturers go online, and I always lean towards established ones.
This inverter can handle up to 12000W of surge for up to 20 seconds, and the features and protections it provides at this price are exceptional.
If you are looking for a heavy-duty inverter for your industrial truck to run tools, an RV, or an off-grid cabin, this inverter should be on your list of top inverters for consideration.
Note that the price I have listed is for ShopSolarKits . It is the same as the Amazon price. The benefit of buying from SSK is customer service. You get the expertise of AIMS and excellent support from SSK.
Features: 12,000W surge, 33 AMPS, low frequency, auto transfer switch,115A smart battery charger, supports eight battery technologies – Lead, Gel, AGM, LiFePO4, etc., Protections (overload, over temp, high voltage, low voltage, short circuit, internally fused, low and high voltage alarm, cooling fan, isolated ground neutral, etc.), AC direct connect terminal, current control dial, priority switches, auto-gen start, coated, power save mode, battery temp sensor, 72 pounds, dimensions: 23.5 x 8.59 x 7.05 inches, remote starter (optional), control panel (optional)
Features: 8,000W peak surge, LED Display, 4x Battery Cables, Internal fuses:16*30A, 12V AC120V, high frequency, 4xAC Outlets, 1×2.4A USB port, remote control w/30 ft. cable, Protections (Over voltage, Low voltage, Overload, Short circuit, Overheat, polarity reverse protection(fuse). Auto-restart function & GND protection from leakage of electricity (lightning strike). Intelligent cooling fan, Isolated Input/Output Design, Soft start tech, 24.3 pounds, dimensions 18.9 x 7.8 x 6.1 inches.
The WZRELB inverter provides a good combination of quality and price. You get an excellent pure sine inverter at what is currently the best pure sine price on this list.
This is a compact converter, so if you want something that fits behind or under your seat while still providing an impressive amount of power while running quietly, then this is a good choice.
Features: 8,000W peak surge, LED Display, 4x Battery Cables, 12V AC120V, high frequency, 2xAC Outlets, 1×2.4A USB port, remote control w/30 ft. cable, Protections (low voltage alarm, overload, over current, surge power, reverse connection, short circuit by fuse). Intelligent cooling fan, 15.9 pounds, dimensions: 18.11 x 8.15 x 3.66 inches
However, if you are looking for a low-budget inverter and don’t have sensitive equipment to control, such as a CPAP and other sensitive equipment, then consider the Kreiger or Energizer Modified Sinewave Inverters.
If you have sensitive equipment or are concerned about the long-term effects of modified sinewaves on your equipment, then the Giandel and WZRELB are good Pure Sinewave Inverters.
If you want a powerful low-frequency inverter, AIMS is an excellent inverter.
