Lithium solar batteries

In this section of our website, you can find solar lithium batteries. Energy storage allows you to retain power at home during outages and save money using your backup during peak electric rates. Let’s look at the subject of picking lithium battery for solar system.

Applications of lithium solar batteries

There are tons of ways you can use batteries for your home, business or trailer. Let’s take a quick look.

Home energy storage

Lithium-ion batteries are used for storing excess solar power during the day for nighttime use. They provide backup power during outages and reduce reliance on grid electricity during peak rate periods.

Lithium batteries for solar panels are particularly valuable when it comes to off-grid living. You can power remote cabins and vacation homes with them, and run water pumps and essential systems in remote locations. Overall, lithium batteries for solar systems are great for supporting full-time off-grid residences.

Commercial and industrial uses

Battery storage is essential for providing backup power for critical business operations. You can support commercial solar installations with batteries, power remote telecommunications equipment, run security systems and emergency lighting.

Mobile and RV applications

Batteries are very helpful for small-scale applications. Lithium batteries for RV solar systems can power everything in your trailer, such as AC, laptop or microwave. They can even support mobile businesses like food trucks. You can use them for charging portable electronics, powering outdoor lighting systems, running small workshops or garden equipment, or supporting outdoor events and temporary installations

Key advantages of lithium solar batteries

Lithium ion solar batteries last much longer than traditional lead-acid batteries - typically 10-15 years compared to 5-7 years. They can handle many more charge cycles before their capacity starts to decline. They're much lighter and more compact, taking up about half the space of lead-acid batteries with the same capacity. This makes them easier to install and gives you more flexibility with placement.

Performance-wise, lithium batteries are more efficient at storing and delivering power. They can be discharged more deeply (up to 80-90% of their capacity vs 50% for lead-acid) without damage, so you get more usable energy from the same battery size. They require basically no maintenance - no need to check water levels or deal with corrosion like you do with lead-acid batteries. They also work better in cold weather and can charge faster. Lithium-ion batteries are also safer than older battery types - they don't release gases during charging and are less likely to overheat. Modern lithium batteries include built-in protection systems to prevent issues like overcharging.

The main downside is the higher upfront cost. However, when you factor in their longer lifespan and better performance, lithium batteries often end up being more cost-effective over time. That’s why we would advise against the cheapest lithium batteries for solar systems, simply because the battery has to be high quality in order to serve your house for many years.

How to select right lithium solar battery

First, calculate your daily power needs. List all your appliances and devices, their wattage, and how many hours you use them daily. This gives you your total daily energy requirement in watt-hours (Wh). Add about 20% as a safety margin. Next, consider how many days of backup power you want. If you live somewhere sunny, you might only need 1-2 days of backup. For cloudier climates or if you need more reliability, aim for 3-4 days. Multiply your daily needs by these days.

Look at the depth of discharge (DoD) rating. While solar lithium batteries can typically discharge to 80-90%, it's wise to be conservative in your calculations. Use 80% as a rule of thumb to extend battery life. Check the battery's cycle life - this tells you how many charge/discharge cycles it can handle before significant capacity loss. Look for batteries rated for at least 3000-4000 cycles for good longevity.

Consider your voltage requirements. Most home solar systems use either 12V, 24V, or 48V lithium solar batteries. Higher voltage systems are typically more efficient for larger installations. If you live somewhere with extreme temperatures, make sure the battery is rated to perform in your climate. Some batteries need additional cooling or heating systems.

Top lithium solar battery models

The Tesla Powerwall 2 is a popular choice that can store 13.5 kWh of power. It comes with its own inverter built in, and you can easily check how much power you're using through an app on your phone. Tesla offers a good warranty, and these units are known to last. While not the most modern one, it is still one the best lithium batteries for solar.

LG's RESU 16H Prime can store even more power - 16 kWh. It's pretty compact, so it won't take up too much space in your home. It works well and has proven itself reliable over time. Some consider it to be one of the best lithium batteries for off-grid solar.

BYD Battery-Box is flexible - you can start small and add more batteries if you need more power later. You can build it from 5.1 up to 23 kWh. It's safe and easy to install, which installers really like.

The Enphase IQ Battery comes in two sizes - a smaller 3.36 kWh version and a bigger 10.08 kWh one. It's very reliable and easy to add more batteries later if you need them. Since the capacity is small, it is the best lithium battery for RV solar systems on this list.

Connecting batteries to solar panels

How exactly you’re going to connect batteries to your solar system depends on the kind of battery you have. For example, there are DC and AC batteries. DC batteries can be connected to a hybrid inverter that supports both energy storage and grid connection. AC batteries come with their own battery inverter and you don’t need a hybrid inverter to add them to your system. They are more expensive though.

Generally, you don’t add batteries to your home solar system yourself unless you really know how to do it. Find contractors that are willing to take on the job and explain the situation to them.
