Batteries
A solar battery is an intelligent solution for an independent power supply in your motorhome, boat or garden shed. With it, you can permanently supply electrical devices such as lights, refrigerator and radio with power. At Offgridtec, we offer a wide range of battery technologies as well as professional advice to help you make an informed decision and get the most out of your solar system.
Types of solar batteries
In our online shop you will find four different types of solar batteries:
- Lithium-ion
- Powerstations
- AGM batteries and
- Gel Batteries
These differ mainly in their electrolyte fluid and the way they are constructed. Depending on the area of use, batteries have different ampere-hours and electrical voltages, the latter usually being between 12V and 24V. The current strength, i.e. the ampere hours, on the other hand, vary more:
- 100ah, 120ah and 200ah for lower demand
- 280ah, 300ah, 400ah and 500ah for higher demand
We will be happy to tell you which battery is best suited for your purposes in a personal consultation.
Advantages of a solar battery
With a solar battery, you store unused solar energy for later. This increases your self-consumption, consequently reduces your dependence on your electricity provider and thus, of course, your electricity bill.
However, due to the different types of batteries, the benefits they bring also vary. For example, lithium-ion batteries are an increasingly popular option for homes and businesses because of their ease of installation. They can be easily and safely installed in dry basements, saving you from having to rebuild the building.
In general, however, solar batteries have a longer service life than others and also impress with a particularly low discharge limit as well as a high cycle stability.

FAQ
- Which is the best solar battery? That depends on what it is to be used for. In principle, the lithium-ion solar battery is a popular choice due to its service life and performance. For boats and ships, however, an AGM or gel battery is more suitable, as these types are very leak-proof.
- Which batteries are suitable for solar systems? Lithium-ion solar batteries, gel solar batteries and AGM solar batteries are particularly suitable for solar systems.
- What is the service life of a solar battery? How long a solar battery lasts always depends on its quality and the technology used. Lead storage batteries usually last about 5-15 years, whereas lithium storage batteries last about 10-15 years.
- How big does my solar battery need to be? To find out, multiply the total daily power requirement (watt hours) by the number of days you want the system to function without sunlight. Then add 30% capacity reserve to get the required battery capacity in watt-hours. If this value is now divided by the battery voltage (V), you get the required battery capacity in ampere-hours. Please note that batteries may only be discharged up to a certain value. (e.g. AGM batteries up to max. 50% → required battery capacity x2).
