12 volt deep cycle battery solar charger full#
This is where the sun is giving the solar panel a full amount of juice that it can convert to energy. Generally speaking, there should be about 5-hours of effective charge time per day. Your battery voltage is likely going to be 6v, 12v, or 24v.īoth the AH and the voltage will be listed on the battery, so it shouldn’t be that much of a problem finding out that information. VIEW DEEP CYCLE BATTERIES ON AMAZON Battery Voltage Obviously, if you are not fully discharging your battery, then the charge time will be a lot quicker than the numbers that we give. We are going to be working on the assumption that you are discharging your battery down to the 20% mark here. In the case of 100ah, your real capacity would be 80ah. Now, because you are only supposed to discharge a deep cycle battery up to 80%, the effective capacity is much lower than this. For most deep cycle batteries in RVs, this will either be 100ah or 200ah.
The battery capacity is the amount of power that your battery can hold. In order to work out how many watts you need for your battery, there are a few pieces of information that you will need to hand. In our opinion, this would be within a day of charging. It is how many watts it would take to charge the battery in a reasonable amount of time. To be honest, the main concern here isn’t how many watts it would take to charge a deep cycle battery.
It wouldn’t be that effective, and your battery would likely take over a year to charge, but it can be done. In theory, you can charge a deep cycle battery from a 5-watt solar panel.

This is why this is the only type of battery that you should be using in your RV. No other battery type is going to be able to put up with the constant charge and discharge cycle that a deep cycle battery has. Basically, you will be deep cycling their power. It is designed to be fully charged, and then discharged down to about 20% capacity. Well, a deep cycle battery is designed to offer sustained power over many hours.
What Conditions Can Impact How Fast the Battery Charges?.How Many Watts of Solar Panel to Charge Deep Cycle Battery?.We are going to try and answer all of your most burning questions on this page. Perhaps more importantly, how quickly that deep cycle is able to charge depending on the number of watts that you give the battery. If you use a 100-watt solar panel, you will need 15 hours of sunlight or an average of 3 days to charge your battery. However, you must keep in mind that the wattage required depends on the amount of sunlight and the battery capacity. One question we get asked a lot here is how many watts of solar power energy it will take to charge a deep cycle battery? On average, you need a 300-watt solar panel to charge a 12 V 100 Ah deep cycle battery within 5 hours of sunlight. This means that when you are not running the generator, or there is enough sunlight about, you are still going to be able to charge your battery. It is these batteries that will store any excess power produced by your generators or solar panels. If you have an RV then, chances are, that it will be loaded with deep cycle batteries.
