We’ve talked a lot about batteries over the years and provided our readers with several options to help them set up the ultimate off-grid solar systems, but technology has brought us to a place where today, the best option in almost all cases is going to be deep-cycle lithium iron phosphate (LiFePO4) batteries.
Deep-cycle lithium iron phosphate (LiFePO4) batteries
Lithium-ion technology has had a significant impact on how we power our electronic devices. The technology is now used in everything from consumer electronics such as mobile phones, laptops, and drones to electric cars and off-grid solar power systems.
In testing, Lithium batteries outperform every other type of off-grid battery when it comes to storing energy from a solar system. In addition, they’re more efficient, charge faster, require no maintenance or ventilation, and last significantly longer. While they are more expensive up front, the operating cost over time makes them the most cost-effective option on the market.
Lithium-Ion Batteries are Great for Inconsistent Solar Charging
One of the most significant drawbacks to using older lead-acid-based batteries in solar systems is the way they operate and charge. Because of the nature of solar, charging conditions can be inconsistent due to weather, location, and time of year. This is brutal on lead-acid-based batteries, and inconsistent charging can damage your battery system.
