Best Inverters & Inverter Chargers: All You Need to Know

More people than ever before are utilizing Solar Power Storage Systems thanks to the growth of clean energy because they offer a durable, effective, and adaptable way to power numerous pieces of equipment. Regardless of your intentions of becoming self-sufficient, you will require an energy source, an effective battery bank, and a solar inverter. Solar power Inverters can be incredibly helpful in various settings, whether you are a camper, live off the grid, or need backup power.

This article covers everything you need to know about inverters and inverter chargers, including the best brands available in Canada. If you're thinking of buying one of these devices, this article will help you get started.

Solar Power System in a Nutshell

Having a Solar Power system and producing your own clean energy is an important task that you should do thorough research before investing in. All components and equipment you need on the roof of your residential or commercial building, RV, camper van, or boat to install a solar power system are worth investigating. This is because they work together to produce power as efficiently as possible. As a result, a malfunction in one of these components will drastically reduce the efficiency of the entire system.

Every Solar Power system has four crucial components: 1- Panneaux solaires 2-  Solar Inverter 3- Battery Bank 4- Solar Charge Controller. In our previous blog posts, we discussed in detail about:

•  Different types of solar panels and provide a thorough 101 Guide for solar panel buyers.
• Different types of solar batteries (Deep cycle batteries, LiFePo4 batteries, Lead Acid and AGM batteries)
• Why you need MPPT Solar Charge Controller for your grid tie or off grid solar system and Introduce the best solar charge controller in Canada currently available on the North American market
• What are inverters, some basics about Solar inverters (Such as Hybrid Inverter, Micro Inverter, grid tie inverter and pure sine wave inverters)

Of all the components of a grid-tied solar system, the solar inverter is the most complex and, regrettably, also the most susceptible to malfunction. This is not unexpected given that inverters are typically installed outside in harsh weather, such as rain, snow, humidity, and excessive heat while producing thousands of watts of power for up to 10 hours each day. For this reason, it's crucial to utilize a high-quality inverter, specifically in Canada, which experience harsh weather conditions in some area for more than six months a year.

In this article, we want to focus on factors that you should consider when you want to buy inverters, some important features you should check in any solar inverter’s spec sheet and review the best off grid inverters in Canada.

What are the differences between an Inverter and an Inverter charger?

In order to get familiar with Solar Inverters and Inverter charges, we should first discuss some basics: AC and DC power. Your typical household electronics are powered by AC. As a result, everything plugs into a wall socket uses AC power.

On the hand, batteries hold DC power, which is the sort of power. DC power is used by anything that plugs into a USB port or cigarette lighter and by automobiles to power their electrical systems. Everything that has a battery internally uses DC power. Additionally, you can use DC power to run custom electronics like vent fans, water pumps, and lights.

Converters and inverters are devices that allow switching between two types of power in everyday life:

• Converters: Turn AC to DC power
• Inverters: Turn DC to AC power

In this regard, a converter is needed to get city power into your battery bank and an inverter to run household AC electronics. Inverter chargers combine converters and inverters into one compact device. 

Moreover, with no exhaust emissions, fuel, or noise to contend with, an inverter charger is a quieter option for gas generators. The solar inverter charger enables you to operate the generator less frequently, saving gasoline, even during protracted outages when you might occasionally need to run it to replenish the batteries.

What Factors should you consider when choosing a solar power inverter?

Manufacturers generally provide you with a datasheet or spec sheet of the product you want to buy, and these documents have complete detailed information about that product. Reading this technical information for a general customer without any technical background or experience is impossible. We will review essential factors you should check in any spec sheet of the Inverters or Inverter chargers before buying them. In this regard, you won’t need to read through those confusing tables, figures and pages to find the best option which fits your needs.

Important Note!

Both inverters and inverter chargers draw current from batteries to power devices. Still, only inverter chargers can connect to AC sources, transmit AC to devices, charge batteries, and switch to battery power when AC power is unavailable. An inverter that is not an inverter charger can recharge batteries by running an automobile instead of connecting directly to an AC source.

Voltage In/Out

Inverters are typically powered by 12V batteries. There are also heavy-duty inverter chargers that use 24V, 36V, or 48V batteries for applications requiring larger wattages. Ensure the input voltage of the inverter you select is compatible with your batteries. 

On the other side, North American homes receive 120 volt AC power from the electrical provider. Make sure your inverter's output is compatible with 120V service if you live in North America to power your gadgets, tools, or small appliances.

Continuous Power vs. Peak

Numerous machines, devices, and pumps need transient power spikes to start up, run, or do both. This indicates that additional temporary wattage is needed over the inverter's continuous power rating. Find an inverter or inverter/charger that can offer up to 200% of its continuous power rating during times of high power consumption.

Input Connection

Heavy-duty inverters have DC input terminals that can be directly wired to connect to batteries. Batteries can recharge when there is access to shore power thanks to inverter/chargers that are connected to both the batteries and an AC power supply.

Cooling Fans

The lifespan of your inverter is increased with multi-speed cooling fans, which reduce heat accumulation.

3 Phase Inverter Charging

The innovative 3-stage charger used by Inverter Chargers recharges batteries more quickly while safeguarding them from overcharging, over-discharging, and unintentional depletion.

Continuous Output Rating

Find out how much power each connected gadget needs in general. The combined wattage of all the devices that will be powered simultaneously must be greater than the inverter's or inverter/charger's output rating.

Resettable Circuit Breakers

Defend your inverter/charger against overload or charger malfunction harm.

Other Features

Think about whether you require any of these extra characteristics when purchasing an inverter or inverter/charger to safely and effectively power your equipment:

• High Initial Power
• USB Ports
• Pure sine wave output
• UL Certification
• Remote Control Capabilities
