How Many Types of Solar Inverters Are There?
Solar inverters are classified differently, but there are four types you should concern yourself about.
String Solar Inverters
String solar inverters are typically installed in rows and connected by strings of solar panels, with each string transferring DC power to the inverter, which converts it into AC power. They are relatively affordable and quite easy to diagnose whenever a problem arises within the system. They can be used for both residential and commercial purposes.
Hybrid Solar Inverters
These are becoming more popular by the day. Hybrid inverters are also called battery-ready inverters, and they typically feature a solar and a battery inverter in a single unit. They function in the same fundamental way as string inverters, in that they convert direct current into alternating current that can be utilized for your appliances and devices at home. In addition to this, hybrid solar inverters can also serve to charge and discharge solar battery banks.
Micro Solar Inverters
Microinverters are small in size and capacity and are designed to be installed directly into solar panels. In contrast to central inverters that convert the whole energy produced by the system, micro solar inverters are attached to individual panels. As such, they are responsible for the conversion of the panel they are attached to.
Off-grid Solar Inverters
Also referred to as stand-alone inverters, off-grid inverters are used in power systems that are entirely isolated from the main power grid. They also perform the same essential function of converting DC into AC. Nevertheless, they cannot send power to the main grid.
They take power from the batteries and convert it into a more usable current type for your home appliances. Compared to grid-tied inverters, they can be more complicated due to the incorporation of too many components. If you are to create a backup power generating system for your home, boat, or RV, this is the most likely inverter type you need.
Grid-tied Solar Inverters
They are like basic versions of off-grid solar inverters but are designed to connect to the main power grid. This makes it possible to transfer any excess solar electricity produced back into the main grid. In some locations, the owner will receive a feed-in tariff. Because they typically feature two main components, they are easier to wire, compared to off-grid options.

Choosing a Solar Inverter – Things to Consider
If you hope to get a functional solar inverter, you should have some criteria to reference when comparing different models. Here are some things to consider before you choose a solar inverter.
Wattage
One of the things to establish in the planning stages of any solar power system is the wattage of inverter required, in addition to the wattage of the panels. These factors are all influenced by the energy need of the user. Establishing your wattage need will make your search easier, as you will get lesser recommendations than when you are not informed about the wattage you need.
Efficiency
These days, manufacturers cannot be trusted when it comes to the efficiency rating they attach to their products. Nonetheless, it is always close to the true peak efficiency. No solar inverter can be 100% efficient. The nearer the rating is to a hundred, the more efficient the inverter. We recommend that you ignore any inverter with a peak efficiency of less than 90%.
Durability
Durability is also quite essential. It will inevitably affect the inverter’s lifespan. This is why it is essential to ensure that strong materials are used and the overall build quality of any device. As solar inverters are prone to some electricity hazards, you should also check for protection against overloading, over heat, short circuit, and more.
Ease of Installation
If it comes down to you to install and configure the inverter personally, you should go for a model that has a straightforward installation. We don’t recommend DIY installation if you are not experienced in solar system solutions. Nevertheless, some inverters are quite easy to install, even for people with minimal knowledge of electrical connections.
Conclusion
Current coming directly from solar panels and batteries is always in direct current form and has to be converted to alternating current for electrical appliance sand devices. For your off-grid and on-grid solar power system, these are some of the best solar inverters you can use with your panels and batteries. These inverters are powerful enough to convert power for major household appliances, boats, and even RVs. We hope you found this best portable solar inverters review helpful.
