What is the Best Inverter for Lithium Ion Battery: A Brief Guide (2024)

We should start off by pointing out that decent inverters are necessary for operating any standard or renewable energy systems, even more so for systems that incorporate lithium ion batteries.

Given the size and potency of today’s lithium batteries, inverters are essential for any system that handles huge loads at any given moment. Not just that but they are also more apt at handling fluctuations in a solar or wind power system without stressing the batteries themselves.

As a matter of fact, renewable energy systems are more or less dependent on quality inverters, especially if the focus of the system is a battery bank or arrangement that relies on large energy storage components.

With that in mind, let us take a look at some of the best inverter for lithium ion battery and find out why they’re considered essential in such systems in the first place.

Top 5 Best Inverter for Lithium Ion Battery

What to Look For in an Inverter for Lithium Ion Batteries

Looking for an inverter or any other charge controller for that matter may prove a bit challenging if you don’t fully understand what to look for. In that regard, know that an inverter doesn’t produce power but rather handles output voltage, input voltage, power, and frequency.

What is a Lithium Battery Inverter?

While most inverters are compatible with lithium batteries, specific lithium-oriented inverters do exist and they are configured to deal with the specific voltaic charge of lithium batteries.

Know that as opposed to lead-acid batteries or other battery types, lithium batteries deliver a much steadier charge, which is specifically what lithium battery inverters are designed to handle.

When it comes to solar or wind power systems, the steady flow requires an inverter to handle the watt-hours output and voltage as per the battery’s power density.

Do Lithium Batteries Need Inverters?

Although most lithium batteries come with inbuilt protection systems to allow them to be charged via conventional methods, it does happen that the battery charger fails to reach the desired voltage during the charging process.

When that happens, an inverter will alter the charging voltage in order to deliver a steady flow of power to the battery. Regardless of the power source, the use of an inverter ensures that your battery doesn’t suffer from infrequent voltage which may damage it over time.

Inverter Requirements and Standards

A quick glance at what the market has in store will tell you that inverter chargers are easy to come by, just as easy as lithium batteries. For that reason alone, picking a decent inverter might prove a bit challenging.

The first thing you need to consider is the voltage. Unlike lead-acid batteries that come in a 2V/cell standard, a lithium battery uses a 3.2 V standard.

So a 12 V battery will have 4 cells connected in the series, reaching a total voltage of 12.8 V. As such, a suitable inverter will have to handle 12V at the very least, although 24V and 48V models also do the trick.

Calculating the Power Requirements

When choosing a battery+inverter setup, it couldn’t hurt to first figure out what your energy requirements are and how they might change over time. You can do this by calculating the power requirements of your devices based on how much power they use.

While most cell phones and tablets have relatively small energy requirements, larger devices and appliances use a lot more power overall. So the first step here would be to figure out the volt-ampere supplied to the appliance by the inverter.

Bear in mind that the inverter capacity generally reflects how much electricity it can supply at any given time whereas the battery capacity reflects how much electricity it can store. In this regard, lithium batteries differ quite a lot from lead-acid batteries or any other battery types for that matter.

Best Inverter for Lithium Ion Battery: Conclusion

The quest for finding the best inverter for lithium ion battery shouldn’t be too difficult given the wide range of inverters available at the moment. And although not all manufacturers build them to the same standards, you can generally use reviews as a way of determining if an inverter is worth the investment.

We even talked about portable inverter generators today, which is definitely something you should look for if you have the budget. This is because inverter chargers can be easily adapted to fit complex energy systems, be they portable or stationary.

At the end of the day, however, you want to keep an eye out for an inverter that suits your energy requirements and one that hopefully comes in a compact size so that it’s easier to attach.
