Best 36 Volt Inverter – Modified and Pure Sine | SolarKnowHow

24V Solar Power Inverter

The goal of this article is to help you choose a 36-volt inverter. These inverters are not as common as some of the smaller size inverters, and I’ll help you narrow down and review your choices.

This article will review inverter choices, why you should consider a 36-volt inverter, and then review your best 36-volt inverter choices.

Why Buy a 36-volt Inverter?

A  36-volt inverter is a device that converts 36V Direct Current to 120V (110v) Alternating current. In other words, it takes current from a bank of batteries (36V) and converts it to similar power supplied by the grid to power your appliances and devices.

I suggest you use A 24-volt inverter, 36-volt inverter, or 48-volt inverter when you need to power appliances over 3000 Watts.

When you use a 36-Volt inverter, you can use regular or more flexible connectors to connect the inverter to the battery bank. Keep in mind that the thinner the wire, the higher the resistance. If your DC voltage is lower, you will pass more current through the cables, and in addition to getting hot, you lose battery power.

Below is a list of 36-volt inverters available online and more information about different types of inverters.

Criteria for Choosing an Inverter

Choosing the right inverter is important. To make the process as easy as possible, we have put together a list of key points to consider when selecting your inverter.

  1. Rating: It is essential to determine the wattage required to operate your appliances. Although it may seem convenient to purchase an inverter large enough to run all desired appliances and accessories, the drawback will be the inverter’s added cost.

    It is important to confirm the exact power requirements of all electrical appliances and accessories you will be used simultaneously. Do not underestimate normal usage. Doing so will only lead to disappointment and more expense. Here is a rating chart that will help you choose.
  2. Noise: Noise is not a pleasant sound for anyone, especially in the 21st century, where everyone is busy and needs fewer distractions. Choosing an inverter with less noise is a choice that should not be ignored. If you plan to use your inverter for noisy power tools, you will not need to spend the extra money to buy a quiet inverter.
  3. The number of power outlets: Power Inverters are available with single outlets to power one device and multiple outlets (two or three outlets) to power multiple devices simultaneously. You need to decide on the number of power outlets you will require.

    Many higher wattage inverters also come with hard-wire ports that let you connect the inverter to your cabin’s or home’s power distribution system. In this case, you may not need the power outlets.
  4. The number of USB Ports: Some power inverters come with Universal Serial Bus (USB) ports, which allow you to charge a wide range of electrical and electronic appliances, including cellphones, laptops, game consoles, power tools, and other household products. They come with or without power outlets, and their USB port feature allows smartphones, iPhones, Tablets, and other USB product users to charge their devices easily. 
  5. Safety Features: To prevent your battery from draining while charging, leaving you stranded, some inverters incorporate a safety feature that cuts off power to the inverter once a certain internal temperature is reached, i.e., before the battery is completely dead. Another essential safety feature that is beneficial and present in some models is the surge protector, which cuts power if a power surge or overload is detected.
  6. Size: The inverter’s size is determined by the space in your boat, RV, or home area. Make sure the inverter can fit into the place you have for your inverter.

Types of Inverters

Modified Sine Wave Power Inverter

This inverter type is a reliable, economical choice capable of running most devices and fundamental household appliances. They cost less than the pure sine wave inverters.

However, they can damage sensitive devices. For example, microwave wave electronic control panels often will not function properly on a modified sine wave inverter. The more sensitive the device, the less likely it will work on a modified sine wave. Many users have complained that their CPAP machines do not function properly with a modified sine wave inverter.

Pure Sine Wave Power Inverter

The pure sine wave inverter is more efficient than the modified sine wave inverter and almost twice as efficient when used to power certain appliances. They are perfect for running appliances and powering sensitive electronics such as microwaves that pull a large amount of current. They are, however, more expensive than the modified sine wave power inverter.

Two Types of Pure Sine Wave Inverters

There are 2 types of pure sine wave inverters, low-frequency (LF) pure sine wave inverters and high-frequency (HF) pure sine wave inverters.

  1. The LF inverters use a big copper transformer, which is bigger, heavier, and more expensive. They are also better with equipment that requires high starting power, such as compressors and air-conditioners, primarily if used regularly or for long periods of time.
  2. The HF inverters use smaller transformers and electronic components. They are lighter in weight and are less expensive. These are good for the occasional user. There is no need to spend so much on an inverter if you only use it for a few hours a week. These inverters are also perfect for electronic equipment and smaller devices, even when used for several hours daily.

WZELB Pure Sine 3000W/6000 Watt Peak 36V

24V Solar Power Inverter

In the 36-volt category, WZELB makes a very good inverter. The inverter comes with cables, a replacement fuse, and numerous safety features such as overload, overvoltage, short circuit shutdowns, etc.

This inverter is flexible and easy to use with 2xAC outlets, a digital display, and a terminal block for hard wiring.

AIMS Modified 5000W/10000 Peak 36v Inverter

AIMS 36-volt Modified Power Inverter

AIMS 5,000W modified inverter with 10,000 peak is a serious inverter for running equipment for your off-grid projects. This inverter has 4xAC receptacles, is wired for a remote on/off switch, AC Direct wiring terminal, and has numerous protections – Over Temperature protection, Overload protection, etc., a single cooling fan operation thermally controlled, etc.

This workhorse will provide you with the power you need.

XYZ INVT Pure Sine 3000W/6000W Peak 36v Inverter

The XYZ INVT is another popular 36v inverter with good consumer feedback. This is also the least expensive 36v inverter in this group.

This is a simple, straightforward inverter with 2xAC outlets, an AC connection for hardwiring, and numerous safety protections – Short circuit protection, High-Temperature Protection; High Volt Protection; Low Volt Protection; Surge Protection; etc.

Battery cables and extra fuses are also provided.

Summary

When choosing your pure sine wave inverter, make sure you choose the one most suitable for your needs. The more expensive ones are the LF inverters, and the less expensive ones are the HF inverters.
