Solar Batteries & Storage Solutions – AGM, LFP & Power Stations

A solar battery is a smart solution for independent power supply in your motorhome, boat, or garden shed. It allows you to permanently supply electrical devices such as lights, refrigerators, and radios with power. At Offgridtec, we offer a wide range of battery technologies and professional advice to help you make an informed decision and get the most out of your solar system. Find the right energy solutions for your project today.

Types of solar batteries

In our online shop, you will find four different types of solar batteries:

• Lithium-ion
• Power stations
• AGM batteries, and
• Gel batteries

These differ mainly in their electrolyte fluid and the way they are constructed. Depending on the area of application, the batteries have different ampere hours and electrical voltages, with the latter usually ranging between 12V and 24V. The current strength, i.e., the ampere hours, varies more:

• 100ah, 120ah, and 200ah for lower demand
• 280ah, 300ah, 400ah, and 500ah for higher demand

Solar storage and batteries for photovoltaic systems

Solar batteries are also known as solar storage units or rechargeable batteries for photovoltaic systems. Their main task is to store the energy generated by solar modules or solar panels and release it again when needed. This means you can use electricity not only when the sun is shining, but also to reliably power your devices at any time of day.

At Offgridtec, you will find many different types of energy storage systems – from compact AGM batteries and modern LFP rechargeable batteries to mobile power stations. We cover a wide range of applications: from use in motorhomes, boats, or garden sheds to powerful backup systems for homes and businesses.

A suitable solar storage system increases your system's self-consumption, reduces your dependence on the power grid, and makes you less vulnerable to rising energy costs. Our experts will be happy to advise you on the storage solution that is best suited to your project.

Advantages of a solar battery

With a solar battery, you can store unused solar energy for later use. This increases your self-consumption, reduces your dependence on your electricity provider, and, of course, lowers your electricity bill.

However, the advantages vary depending on the type of battery. For example, lithium-ion batteries are an increasingly popular option for homes and businesses due to their uncomplicated installation. They can be easily and safely installed in dry basement rooms, saving you the hassle of renovating your building.

In general, however, solar batteries have a longer service life than others and also impress with a particularly low discharge limit and high cycle stability.

FAQ

1. Which is the best solar battery?
   That depends entirely on what you want to use it for. In principle, lithium-ion solar batteries are a popular choice due to their service life and performance. However, AGM or gel batteries are more suitable for boats and ships, as these types are very leak-proof.
   
2. Which batteries are suitable for solar systems?
   Lithium-ion solar batteries, gel solar batteries, and AGM solar batteries are particularly suitable for solar systems.
   
3. What is the service life of a solar battery?
   The service life of a solar battery always depends on its quality and the technology used. Lead-acid batteries usually last around 5-15 years, while lithium batteries last around 10-15 years.
   
4. 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 the system should continue to function even without sunlight. Then add 30% capacity reserve to obtain the required battery capacity in watt hours. If this value is now divided by the battery voltage (V), you will obtain 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)
   
5. How do I find the right solar battery for my photovoltaic system?
   The choice depends on your power requirements and area of application. Lithium-ion storage batteries are suitable for houses, while AGM or gel batteries are suitable for boats and motorhomes. Our experts will help you make the right choice.
   
6. What is the difference between a storage unit, a rechargeable battery, and a battery?
   All three terms refer to energy storage devices for photovoltaic systems. Rechargeable battery is the technical term, solar battery is the common name, and solar storage emphasizes the function.
   
7. Can I also use a solar battery to operate a system during power outages?
   Yes, modern solar batteries can be combined with inverters to create backup solutions. This ensures that you continue to have power during power outages.
