Solar Batteries, Solar Battery Storage, Solar Panel Battery

Solar battery, Solar battery 12V for motorhomes, caravans, campervans and boats

Solar Batteries - Solar Battery Storage for motorhome, campervan & boat - always available!

You can find here solar batteries that can be used in conjunction with 12V solar panels for the living space in the motorhome. They are excellent suited for the permanent power supply of inverters or other devices. In order that the solar battery is long-lasting, it should slowly be discharged to a maximum of 40% rated power. For a higher discharge up to 50%, we would recommend the Deep-Cycle AGM Batteries or the high-quality lithium iron phosphate solar batteries. The deep-cycle AGM batteries are much more cycle resistant (500 charge cycles at 50% discharge, 1200 cycles at 30% discharge) than most cheap lead-acid batteries. The new lithium iron phosphate batteries can reach up to 2500 cycles at a 90% discharge.

Are you interested? Would you like to see the whole section of solar battery storage? Then just click here to get to our range of Lithium Batteries, LiFePo4!
The right Solar Charge Controller, Mppt Charge Controller also makes a significant contribution to the optimal use of energy in your solar cells. Most solar panel kits come with a solar charge controller.

Do I need a solar battery 100Ah or do I need less or more power?

Solar batteries 100Ah are the most popular solar battery size for campervans, caravans, motorhomes, summerhouses and boats. It is a safe source of power to operate or charge radios, cell phones, flashlights or many other electrical devices. Not everywhere is a shore connection or another type of power supply.
The solar battery will provide your vehicle with enough electricity to operate small devices, this makes you independent from the campsite and the power outlet. The advantage: Due to the electrical connections in your motorhome, caravan, campervan or boat, you can charge the solar battery or take power from the usual socket, even abroad.
The solar battery 100Ah serves as a buffer for your energy. We recommend to calculate the size of your solar battery a bit more generously. A solar battery 12 V 100 Ah should be sufficient for the minimum supply. The stored current can be used at any time and, depending on the size of the solar battery, for a long time.
Constant use is guaranteed even if the solar panels generate little or no power, for example at night.
Practical and inexpensive: Just take two 12 V 100 Ah solar batteries and switch them in parallel, you get double power at 12 V. If you connect the batteries in series, you get 24 V, for example for a truck. More information can be found in our conversion guide!

Charging Solar Batteries of your motorhome, campervan, caravan, sailboat and garden shed

Since the solar cell does not always fully charge the solar battery, depending on the amount of sunlight, you should charge the solar battery 12V as often as possible with a conventional mains charger. This maintains the performance of your solar battery, and you get a good number of charge- and discharge cycles from your supply battery.

The life of your solar and supply battery will be significantly extended if you always charge it properly! After all, broken 12V solar batteries are almost always caused by the fact that the conventional solar batteries are no longer properly charged after the partial discharge. This often causes a deep discharge of the solar battery, which greatly shortens the life of a 12V solar battery.
Caution: Gel solar batteries must be charged additionally for at least 6-8 hours, even if they are already fully charged.

More information about Solar Batteries Gel, Lithium, AGM or Acid can be found in our Conversion Tips&Tricks or at Wikipedia Solar Battery!

Of course, a solar battery in a motorhome, caravan, campervan or boats can be recharged by the sun. However, if the days are dark and charging power is too low, you do not have to stay in the dark.
The solar battery can also be charged via:
  • the alternator with isolation relay(81200)
  • an automatic charger e.g. the charger 10 A (80293)
  • the mains connection
  • or with a power generator
In most cases there is a suitable mains connection for a solar battery available at a marina, campsite or other designated areas

Solar Batteries Lithium, LiFePO4 Solar Batteries

Solar battery lithium, the LiFePO4 solar battery - the latest technology! The lithium solar battery can actually do everything you could want from a solar battery. Compared to the conventional solar battery:
  • they are 3 times lighter - super light(
  • deep discharge for a short time up to 90% possible
  • 3-10 times faster charging
  • 2000-5000 charging cycles
  • 5-10 times the durability
  • to install regardless of location
  • self-discharge not possible
  • complete maintenance-free
The integrated battery management system makes it nearly impossible to charge the lithium solar battery too fast or to discharge the LiFePO4 solar battery too deep. LiFePo4 is a safe solar battery that meets almost every requirement. However, it is a little more expensive than conventional solar batteries.

AGM-Battery, the robust solar battery for solar power in your motorhome

If you are looking for a service or solar battery which is durable and not very sensitive for deep discharges, our AGM-battery is the right one. These solar batteries have proven themselves during the past 5 years to be ideal for motorhomes, camper and caravans as a solar battery because they can be discharged up to 50% and they are not too sensitive for partly loading.
To control the charging process and to protect the solar battery from overcharging, you also need a Solar Charge Controller The acid of the AGM solar battery is bound like in a sponge. So even if the AGM solar battery is damaged, no acid leaks to the outside. The sponge (or rather the flow) also has a supporting effect and protects the lead plates in the AGM solar battery from shocks. Solar AGM batteries have a discharge depth of up to 80%

Gel Solar Battery

Gel solar batteries work independently of position, maintenance-free and closed. Only a small valve regulates the internal pressure of the Gel Solar Batteries if the charging voltage is too high. If this happens, the electrolyte volatilizes and the battery becomes unusable. Therefore, you should also use a high-quality charger for the solar battery. Gel solar batteries can be stored for a long time and they are cycle-proof. The gel solar batteries have thicker lead plates installed. E.g. gel solar batteries can supply more power than, e.g. the solar acid battery. The gel solar batteries also withstand short-term deep discharges. In case of this, the gel solar battery needs to be charged for at least 48 hours. An unloading depth of 70% is possible.

Acid Solar Batteries, good performance for a low price

You do not have high demands on your solar battery? You only need a little bit of electricity every now and then? A Acid Solar Battery is exactly what you need! The acid solar battery must be installed standing. In the interior of the vehicle, it may only be connected in a closed and ventilated room! If you keep an eye on the acid level of your (e.g.) Moll solar battery, you have a cheap 12V solar battery that will last for a long time. A Moll solar battery is made for slow abstraction such as light in the garden shed, a water pump or the like. For slow removal, such as light in the garden shed, a water pump or the like, a Moll Solar battery is made. Acid solar batteries such as the Moll solar battery may only be partially discharged, which should not be a problem in continuous operation, for example in garden sheds. Acid solar batteries have a discharge depth of 50 - 60%
