What is a home battery?

A home battery is a system that allows you to store excess power generated, to use it later when you need it for something. So with the home battery, no power goes to waste and you can regulate what you use the energy for. This prevents you from being in control and will drastically reduce your energy costs over time.

'Battery solar panel', What is that?

As it were, this is a system that allows you to store power with the energy you generate from solar panels. You can easily use this battery at home, which is why it is often called a "home battery. With a battery, excess energy no longer goes to waste. You store it in the battery and use it at a later time. You decide when this time is. A solar panel battery is also a solution when the power goes out, for example. Where others are completely without power, the battery takes over for you at that moment.

How long does a home battery last?

With today's modern technology, solar panel batteries nowadays last longer and longer. Depending on the quality of the brand you choose, this is different for each home battery. In addition, it's also nice to know that brands like BlauHoff offer as much as a 10-year warranty on their batteries. This is also immediately the expected lifespan of the home batteries. 

What capacity (KwH) is appropriate for my home battery?

An easy calculation is to take 1 to 1.5 times the capacity of your installed solar panels. For example, if you have 8 panels of 400wp, this totals 3200wp. A home battery of 3.2 KwH to 4.8 KwH is fine in this case. Of course, this is different for each person because your vision or goal may differ.
For example, do you want to be able to function without power for at least three days? Then you need more battery power than if you only want to use your own power at night.
In this case, it is best to divide the annual consumption of your panels without feed-in by 365. This is your average daily consumption. From there you can decide how many KwH you want for a home battery. By the way, the number of KwH is easy to expand by adding an extra battery. This is only 5 minutes of work.
In short, everyone's requirements are different. In general, solar panel batteries, or home batteries with 5 KwH and 10 KwH are the most common.

What are the benefits of a solar panel battery?

Can you use a home battery year-round?

Home batteries for solar panels are not made to store power for very long periods in the fall or summer and end up spending all winter with it. They can, however, be used for shorter periods of time. Most home batteries can power a household for about one or a few days. 

What are progressive brands for a battery solar panel?

At eigenstroomopslaan.nl we offer you a wide range of different brands. Some have been on the market for some time, others are relatively new. The new brands are often very innovative and use modern technology, so the battery for solar panels can last for decades. In addition, they often offer a warranty of up to 10 years. This mainly applies to the BlauHoff brand, but the Deye brand is also of good quality, lasts a long time and offers a long warranty period. 

How do you know if an inverter is High or Low voltage?

If you have found a hybrid inverter to your liking and you don't know if it is Low voltage or High voltage, we recommend that you look at the specifications under Battery Voltage Range (V). For example, if it says 100-660 there, it is a High voltage inverter. If it says 48-52, then the inverter is suitable for Low Voltage. Basically, we do not supply inverters, but for emergencies, we can always help you or your installer.
