Take Hutch, an American motorhome rider, as an example. Hutch is a photographer. Since he bought an RV 6 years ago, he and his wife have been driving the RV to various countries all the year round to experience different landscapes and cultures. Couples who love to travel, while enjoying the different beauty and culture of various countries, they also gradually developed a strong interest in RVs.
Due to living in the RV for a long time, the Hutch family has a high demand for electricity. In the past 6 years, due to the frequent use of lead-acid batteries, the endurance of lead-acid batteries has dropped significantly, and the batteries are not enough for one day’s power demand. For this reason, he has replaced three lead-acid batteries of different brands, but the power problem is still plagued. Hold him. The Hutch couples yearn for a free and unconstrained camping method. After many understandings and explorations, they chose a more efficient lithium iron phosphate battery for their motorhome life.
After browsing some solar energy and lithium iron phosphate products on the Cheyou Forum, after comparing product features and prices, Hutch finally purchased a lithium iron phosphate battery. When receiving the lithium iron phosphate battery, Hutch was very surprised. The volume of the lithium iron phosphate battery is only one-half of the volume of the lead-acid battery used before, and the weight is only one-third of the lead-acid battery.
His previous lead-acid battery is 78AH, 12V, which can provide him with 936WH of power, but because the capacity of the lead-acid battery is only half, it can only provide 468WH of power. The capacity of the lithium iron phosphate battery is 100%, so a 50AH, 12V battery can provide 600WH power, which is 132WH more than its previous power. For them, this kind of electric power reserve can make their RV life more free.
Hutch installs the controller and battery under the seat and does not take up space in the RV.The steps to remove the old battery are different from the installation steps. First, disconnect the link between the solar panel and the controller, so that no voltage will enter the controller to avoid danger. The second step is to disconnect the connection between the controller and the battery. Because there may be a small amount of electricity stored in the old battery, it is best to wear gloves when removing it. After disconnecting the controller, and then disconnecting the inverter from the battery, no electricity will enter the inverter and cause damage to the inverter. In this way, the previous old system is completely dismantled.
When installing a new solar system, remember to connect the controller and the lithium iron phosphate battery first. After the connection is made, you can connect the solar panel or the inverter. Pay attention to the positive and negative poles during the connection to avoid component problems caused by the installation of the positive and negative poles. After installation, pay attention to the indicator light of the controller. The indicator light of the solar panel is flashing slowly, and the indicator light of the battery is always on.
What surprised him most is that new lithium batteries rarely drop below 70% of their capacity during use. This spring, when they traveled through Canada, they experienced various weather, including 3 days of occasional cloudy weather. Even at this time, the average battery usage has never dropped below 70%. It seems that the high-quality solar energy is still working weakly in cloudy days, and the solar panels, controllers, batteries, and inverters are among the various components. Only by matching between them can we get stable and efficient power.
Out of curiosity, they decided to test the battery to see how long it takes to completely drain the battery. They start using 82% of the electricity, turn on the inverter, turn on all the interior lights and laptops (for photo and video processing), and use another computer to watch movies. The battery is emptied in approximately 2 hours. Compared with the previous lead-acid battery, it was completely empty and unusable in about 45 minutes.
The quality and efficiency of solar panels are the first. Products with good low-light properties can also get them some electricity in weak sunlight. The lithium iron phosphate battery, which is safer and has a long life, can be regarded as an investment in place, saving a lot of trouble. In the next step, he plans to convert his yacht into a solar system with lithium iron phosphate battery!
