How much can you save with solar?
Need To Store Them When Not In Use
When your panels arent in use , you need to have room to store them. Depending on the type of portable panels you buy, this could require a fair amount of space.
A small folding solar panel isnt a big deal to store away for travel. But larger rigid panels have to travel somewhere, and depending on the size of your rig, they could take up your entire basement storage or even the hallway in the RV itself.
So, when shopping for a portable solar system, be sure to consider how youll store the panels for travel.
Suner Power 20w Mppt Charger
The SUNER POWER 20W charger comes with an MPPT charge controller. MPPT stands for Maximum Power Point Tracking, which is a system designed to extract the maximum amount of available power from a PV module under certain conditions. This type of controller generates 10-20% more power than traditional controllers.
This comes with a polycrystalline solar panel rather than the monocrystalline cells seen in many other solar chargers. This helps keep costs down, as MPPT controllers are pricier than other types of solar controllers. The main difference with polycrystalline is that these types of solar cells tend to be less efficient than monocrystalline.
This charger also comes with a feature that automatically cuts off the charge once the battery has become fully charged. As soon as the battery becomes flat, the charger is activated once again. This eliminates overcharging concerns, particularly when you are not able to routinely check up on the system to make sure that there arent any problems.
The IP 65 waterproof design means that the solar panel is built to withstand rain and snow, as well as the intrusion of dust particles. It is also hard to beat the durability of the ABS frame and the tempered glass cover.

Is It Ok To Use A Trickle Charger On An Rv Battery
You can use a trickle charger on an RV battery but there are a few things you need to think about before you do.
First, making sure you have a trickle or battery charger thats compatible with the type of batteries your RV uses is going to be the most important.
If you have Lithium batteries you are going to need a charger with a setting specifically for Lithium.
Theres some discussion about using a trickle charger on an RV battery while the RV is connected to power so the converter is charging the battery as well.
It seems to greatly depend on the chargers themselves. Sometimes it works to use two at once but sometimes the current of the other charger will keep the charger from charging the battery.
For the most part, its not really recommended since you dont have much to gain from it.
If you want to charge your RV batteries with an external battery charger without having to unplug your RV or unhook the RV wires you can always turn off the converter so only the external battery charger is charging the batteries.
The switch for the RV battery converter is located inside the RV breaker box. Its usually labeled converter.

How Do I Connect A Solar Panel To My Rv Battery
Your solar panel will be connected to a solar charge controller, and the charge controller will be connected to your battery. Read above about why you need a charge controller and the purpose it has.
Connecting the charge controller to the battery can be done in different ways, both permanent and temporary ways.
Standard ring terminals are the more permanent way since bolts will be sitting on top to hold the terminals fastened and connected.
A temporary way can be alligator clips like the clamps you probably have seen on jumper cables. For portable solar panels, alligator clips are the way to go since you can connect them so easily.
If you have solar panels on your RV roof and dont have to disconnect your cables every other day, ring terminals will be the better solution.
When connecting any cables to your RV battery, remember that RED is POSITIVE. BLACK is NEGATIVE.

What Size Portable Solar Panel Do I Need To Charge My Rv Battery
This is a difficult question to answer definitively because there are a number of variables to be considered where solar is concerned. First, theres the size of your battery bank and how much power you use, and then theres the unpredictable variable of the sun itself. But we can address this question in generalities.
You might think that a 100 Watt solar panel will generate 100 Watts of power, but thats not so because there are a variety of factors that will impact the amount of solar power your panels will actually produce. These include cloud cover, time of day, location, and ambient temperature. Even pollution and ozone play a role.
However, theres a rule of thumb that experts use which says that in general, a 100 Watt solar panel will generate around 30 amp-hours per day. This means that on average, your 100 Watt solar panel will put around 30 amp-hours per day back into your battery bank.
Next, youll need to calculate your power usage. Then, remember that your goal is to have your power input come as close as possible to matching about 2x your daily power output/consumption .
If you find that you generally consume around 30 amp-hours per day, remembering the general rule of thumb, a 100 Watt panel will give you around 30 amp-hours per day, so youll want either a 200 Watt solar panel or a pair of 100 Watt solar panels.
