Features of Solar lithium batteries:

Compared with traditional lead-acid batteries, Solar lithium batteries have the following advantages:

  • High Energy Density: Solar lithium batteries have a high energy density, which means they can store a significant amount of energy in a relatively compact and lightweight package. This feature is crucial for solar applications where space is limited.

  • Long Cycle Life: Lithium-ion batteries have a longer cycle life compared to many other types of batteries. They can withstand a large number of charge and discharge cycles before experiencing a significant decrease in capacity. This makes them durable and reliable for long-term solar energy storage.

  • Scalability: Solar lithium battery systems can be easily scaled up or down to meet specific energy storage requirements. It is possible to connect multiple batteries in parallel or series to increase overall capacity or voltage, depending on the application.

  • Safety: Lithium-ion batteries used in solar applications have advanced safety features, such as built-in protection circuits, to prevent overcharging, over-discharging, and excessive temperature rise. These safety mechanisms help ensure the safe and reliable operation of the battery system.

Factors to consider when choosing a solar battery

1. Capacity rating

The capacity of a battery tells you how many kilowatt-hours (kWh) of electricity it can store. The usable capacity dictates how long your battery can send electricity to your home.

Some batteries may show two capacity ratings: the total capacity and the usable capacity. The one you want to pay attention to is the usable capacity, which is how much of the electricity the battery stores that you actually can use.

You should consider batteries with usable capacity ratings of at least 10 kWh, as they’re suitable for most homeowners' energy needs and provide a decent amount of backup power in the event of a blackout.

You can also install multiple batteries to increase the amount of electricity your energy storage system can hold.

2. Power rating

A battery’s power rating represents how much electricity it can deliver to your home at once, measured in kilowatts (kW). The power rating tells you how many - and which - appliances you can run simultaneously.

Solar batteries will usually have two power ratings: the continuous power rating and peak power rating. The continuous power rating is how much electricity the battery can put out continuously (hence the name) for appliances that need a constant power supply, like your refrigerator.

The peak power rating is the maximum amount of electricity a battery can release for a short period of time, which allows you to keep appliances on that need a burst of power in order to get up and running, like an air conditioner.

Most solar batteries have a continuous power rating of 5 kW and a peak power rating of 7 kW, so at the very least you should look for batteries with power ratings in this range. Therefore, if you have a lot of appliances you want to power at once, you should consider looking for batteries with higher power ratings.

3. Round-trip efficiency

The round-trip efficiency of a solar battery represents the amount of energy you can use from your solar battery compared to the amount of energy it took to store that energy.

Say your solar panels sent 10 kWh of electricity to your battery, but only 7 kWh of that electricity was actually stored and can be used. That means 3 kWh were used by the battery’s operating system to store and release the electricity, making the battery’s round-trip efficiency rating 70%.

Our advice is to go for a battery with an efficiency rating of 80% or higher. Higher efficiency batteries can save more money in the long run because more of the solar electricity produced can be used by your appliances, instead of being lost to the battery storing the energy.

4. Lifespan

Most lithium-ion batteries have a battery life of at least 10 years with regular use. As you use a battery, it loses its ability to hold a charge. Think about how fast your cell phone battery runs out after you’ve had it for a few years - the same thing happens to solar batteries.

There are three ways in which the battery lifespan is typically measured:

  • Years

  • Estimated cycles

  • Estimated throughput

The battery cycle life is how many times the battery can be completely charged and discharged. The throughput is an estimate of the amount of electricity the battery will release over a period of time, and will vary depending on the starting capacity of the battery.

5. Battery type

A battery's type is determined by the chemicals within it that are used to store energy. The battery type, or battery chemistry, determines almost every aspect of how the battery system will work.

Although lead-acid batteries were once the most popular battery used for solar-plus-storage systems, lithium-ion batteries have recently become the fan-favorite. There are two main types of lithium-ion batteries sold today: nickel manganese cobalt (NMC) and lithium iron phosphate (LFP).

NMC batteries are more common on the market and are more energy-dense, meaning that they can hold more electricity in a smaller area. They also tend to be a bit cheaper. LFP batteries, however, can last longer than NMC batteries.

6. Safety rating

All of the solar batteries on the market meet a set of strict safety requirements in order to be professionally installed in homes. However, certain battery chemistries are a tad safer than others.

NMC lithium-ion batteries are more sensitive to temperature changes than LFP batteries, which means NMC batteries are more likely to experience something called thermal runaway (AKA catching on fire) if mishandled.

The chances of this happening are extremely low and they’re still incredibly safe to install. But because LFP batteries are more resilient to high temperatures, they are less likely to catch fire, making them the “safest” lithium-ion choice.

How solar batteries work

When your home doesn't need all the energy being produced by your solar panels, the excess energy is stored in the battery. When the solar panels aren't generating enough energy to fill the power needs of the building, the battery discharges reserve power to make up the difference.

The way you configure your solar battery system affects how it works. You have three main options:

  • Connect to your solar panels: Batteries connected to solar panels will fill and discharge frequently in response to the times without sun that you still want electricity. This is useful when in an area that is "off-grid," away from electrical utilities.

  • Connect your solar panels to a solar battery system and to the grid: You can choose to fill your battery and just keep it as a backup, rarely discharging it, and mostly selling and buying excess electricity from the electric company.

  • Use battery during time of use rate spikes: If you live in an area where electricity rates vary with the time of day, you can configure your system to use battery backup at the most expensive times and to buy electricity from the grid at the least expensive times.

Different types of solar batteries

There are several kinds of batteries used in battery backup systems, including lithium-ion, lead-acid and flow batteries. Here's a quick overview of each type.

Lithium-ion batteries

Lithium-ion batteries are the most common for home systems. Most of today's popular battery backup products are lithium-ion, including the Tesla Powerwall, Panasonic EverVolt and Generac PWRcell. They're lightweight and energy-efficient, making them perfect for home use.

Lead-acid batteries

Lead-acid batteries have been used for hundreds of years and are the primary type of battery used in cars. They're cheaper than lithium-ion, but they aren't as efficient, which means they're best suited for small systems.

Flow batteries

Flow batteries (or redox flow batteries) are less common in home systems since they're mainly designed for commercial use. However, the technology appears promising, and it could become more widely used in residential battery backup systems in the near future.

Nickel-cadmium batteries

Nickel-cadmium batteries have a high energy density with double the energy of a lead-acid battery. Nickel-cadmium batteries are very durable, expensive and work well in extreme temperatures making them a good choice for large-scale commercial and industrial projects. Cadmium is toxic, however, and generally not appropriate for residential use.
