Why choose Kostal inverters?

As you know, the solar panel is an essential piece of equipment for supplying your home with green energy. But you should also think about Kostal inverters, which play an essential role in domestic solar installations. The inverter is a device that transforms the direct current produced by solar panels into alternating current.

To make the right choice for your Kostal inverter, Alma Solar talks to you in this post about the different types of Kostal inverters.

How do I buy a Kostal inverter?

#1 - I select my Kostal inverter

Choose your Kostal inverter from our list of solar inverters. You can choose between different power ratings 3kW, 4kW, 5kW, 6KW in single-phase and 3kW, 4kW, 5kW, 6KW, 8kW, 10kW, 15kW or more in three-phase.

Don't forget to also select the type of inverter between Kostal grid inverter (without battery), Kostal hybrid inverter (with battery management) and Kostal charger inverter (to manage the battery only).

What type of Kostal inverter?

KOSTAL has developed its inverters with the aim of offering the best performance on the market. They have reduced the number of inverter ranges to offer 3 types of product today. We are going to present you these ranges in order to guide you in the right choice of KOSTAL inverter.

The KOSTAL MP Plus range of inverters: This range of inverters is single-phase only. These inverters have 2 independent inputs. One of the inputs can be used to connect a BYD solar battery. This solution is therefore scalable. An ideal solution for residential installations.

The KOSTAL Plenticore inverter range: There are 2 types of Plenticore inverter. These inverters are all three-phase. The green Plenticore Plus range offers a solution with 3 independent inputs. Like the MP Plus range, the Plenticore can use one of its inputs to connect a battery. Then there's the new Plenticore G3 range. There are just 3 models to cover the entire power range. The Plenticore G3 S model from 5 to 7kW of solar panels. The Plenticore G3 M model with 8.5 to 12.5kW of solar panels. And the Plenticore G3 L model with 15 to 20kW of solar panels. We have to admit that the new Plenticore G3 range offers a wide power range and, above all, the most competitive prices on the market. The only constraint is that you need to order a code from the KOSTAL website to activate the battery (around €200).

The KOSTAL PIKO range: These high-power inverters are used for commercial and industrial solar panel installations.

How do you choose your Kostal inverter?

ou are probably wondering: Which Kostal inverter should I use? Through this Kostal inverter category page, available in our shop, Alma Solar gives you some advice on how to choose your solar inverter. For your inverter to be suitable for your system, its rated power must be equal to the rated power of your solar system. For example, if your solar system is rated at 2000 watts, you will need an Kostal inverter with around 2000 watts, perhaps a little more. If you want to run more than one appliance at the same time and want to make sure your inverter can handle the load, simply add up all the DC Watt ratings of all the appliances that can run simultaneously.

Finally, we hope this article helps you choose a reliable Kostal inverter with a high storage system that allows you to supply your home with energy and guarantee your self-consumption. Always remember that investing in green energy is a gain! But the worst thing that can happen is that you end up buying something that won't last, forcing you to have your inverter repaired or replaced. So don't hesitate to contact ALMA SOLAR, a leader in the field of solar inverters.
