How Does It Work
A solar battery charger for RV is designed for the maintenance of the batteries in vehicles such as cars, RVs or motorcycles, and other smaller vehicles. Portable solar chargers are generally used for trickle charging, providing your batteries with low-level current continuously. But how exactly does a solar battery charger do this?
Solar battery chargers are suitable for the off-the-grid type of living as it uses energy from the sun to charge your batteries. You dont need other energy sources, only the sunlight. Your solar battery chargers harness energy from the sun and convert it into DC electricity through a photovoltaic array. It is then stored in your battery and used to power it up.
Charging your battery with a 12v solar battery charger is made easy. You dont have to possess the professional knowledge to figure out which goes where. You can easily plug in the charger to your vehicles cigarette lighter.
But there are other vehicles that their cigarette lighter wont work if the ignition is turned off. Conveniently, in this case, solar battery chargers also come with alligator battery clamps and extension cables so you can connect to the battery directly.
How Do You Use A Solar Battery Car Charger
Simply place it on the dashboard of your automobile and plug it into the car DC adapter. It will then utilize sunlight to generate the power bank you need for your vehicle. To ensure the charge is present, the Solar Car Battery Charger has an L.E.D. light that indicates when it is on. It’s that simple.

How Many Solar Panels Do I Need To Charge A 12v Battery
You only need one 12V solar panel to charge a 12V battery.
For instance, a 100 watt solar panel is a common solar panel size you could use to charge some of the most common 12V battery capacities.
But if you have a big battery and you want to charge it quickly, youll likely need to buy multiple solar panels and connect them together to create a solar panel array.
If you just want to maintain a 12V battery, you can get away with a small 12V solar panel, such as a 5W or 10W panel. Thats right a 5W solar panel will charge a 12V battery.
What To Consider When Buying A Trickle Charger
Not all trickle chargers are created equally as they come in a wide variety of sizes, capacities, and price points. The best one for you will have several key features that ensure proper function, reliability, and limited safety issues. The following buying guide will have you making your choice with confidence.

Key Terms To Know Before Getting Started
Throughout this article, we use various technical terms that may be a bit confusing at first. However, here are the key terms we will use and what they mean:
- Amp-hours: How many amps the battery offers in a one hour span.
- Amp rating: Often another word for amp hours, but sometimes refers to amperage and wattage.
- Charge controller: A device that controls when your solar battery is charging, almost like an on/off switch.
- Inverter: Connects to your solar panel to convert unusable DC energy into usable AC energy for your home.
- Solar system: All of the parts used to power your home by solar energy, including the PV panels, connectors, inverter, battery, etc.
- Voltage : Tells you the potential output of your solar panel or battery.
- Wattage: The operating power of solar panels or batteries.
Now that we have gotten the technical jargon out of the way lets dive into solar panel batteries, why you need them, and how to select the right system for your needs.
What Size Solar Panel Do I Need To Charge A 12v Battery
Short answer: Use the calculator at the top of this page.
Long answer: What size solar panel you need depends mainly on 2 things:
If you want to charge a big battery quickly, youll need a big solar panel or solar array. Like how youd need a big hose to quickly fill up a big bucket.
Alternatively, if you want to slowly charge a small battery, you can use a small solar panel. A small hose will eventually fill up a small bucket.
Want to charge a big battery slowly? Or a small battery quickly?
Your solar panel size will fall somewhere in between.
There is no single solar panel size that will be perfect for every scenario. Depending on your battery size and how fast you want to charge your battery, you could get away with using a small 5W solar panel, or you might need a 400W solar array.

Solar Panel Connections For Charging Series Or Parallel
The normal open-circuit voltage output from a so-called 12 volt solar panel is about 22 volts in bright sunshine.
In some cases, with certain types of solar charge controller, its more efficient to connect two in series for small installations such as motorized solar kayaks or small boats.
Two panels connected together in this way would produce double the voltage but the maximum current output would remain the same.
The good news is that most solar charge controllers detect battery voltage and panel voltage, adjusting the charging characteristics accordingly. The charge nameplate normally gives details of the maximum voltages and current for that particular model.

Understanding Voltage For Car Batteries And Chargers
12-volts is the standard for an automobile battery.
Each battery has six cells with 2.1 voltage. When the battery is fully charged, this equals to 12.6 volts of charge in the battery.
If the voltage in a car battery drops, even that 0.6 down to 12.0, theres a 75% difference in power. The power drips down from 100% to 25%.
At 12.4 volts, the car battery is charged to 75%, and 12.2 means the voltage is at 50% charged. That means you can consider your battery charged if it is 12.4 volts or higher but discharged and in need of charging again if its even 12.39 volts or lower.
You can test your car battery voltage by connecting a voltmeter to the battery.
13.5 to 14.5 volts or more should register while the charging occurs with the car on idle. If it is not producing this, the alternator may be having issues and needs to be tested at an auto parts store.

Can A Solar Panel Overcharge A Battery Summary
A solar panel without a solar charge regulator connected will almost definitely damage your battery. The only caveat is if the panel is so small it can only deliver trickle current and maintain a float charge.
What power solar panel to charge 12v battery?
It is possible to directly connect a larger panel to a battery if you also have a load connected thats in regular or constant use. That way the battery will never be in danger of over-charging.
If no load is connected, then the battery voltage must be monitored manually and the battery disconnected when the voltage reaches around 14 volts.

Do Solar Battery Chargers Really Work What Type Do You Need
Yes! Solar battery chargers can fully charge your devices. The only thing is, if the battery has reached the end of its lifetime and needs to be replaced, a simple recharge won’t cut it.
They do take a longer time than gas powered or wall powered chargers but they are a great option for traveling or off-grid living.
Determine which one will work for your needs by answering the questions below:
1. What do I want to charge, something as big as a car or as small as a phone?
If you are looking for a charger for a specific purpose, like charging your car battery, then you can look strictly at solar car battery chargers.
