Solar storage batteries can provide you with guaranteed energy to prevent power outages when photovoltaics cannot generate electricity. When the photovoltaic generates excess electricity, it is stored in the battery. Especially suitable for home installations and electric energy needs of large projects. As a professional solar battery supplier, Solarborn has solar panel battery for sale, welcome to contact us!


Solar Battery Efficiency

Charging efficiency Under specified conditions, the ratio of the output power of the battery when it is discharged to the power input when it is charged. The main factor that affects the charging efficiency is the various side reactions inside the battery. For example, for a general off-grid photovoltaic power generation system, the average charging efficiency is 80% to 85%, which can increase to 90% to 95% in winter.

We offer a complete selection of sealed lead acid batteries. SLA batteries are used in a wide variety of applications, including UPS battery backups, generators, golf carts, and more. These batteries are rechargeable, completely sealed and maintenance free; no need to maintain water levels! Check out our selection below.

Solar Battery Installation

Batteries are generally used in off-grid systems and energy storage systems. The batteries are connected in parallel or in series to achieve the desired voltage, current, or ampere-hours.

Advantages And Disadvantages Of Lithium Iron Phosphate Batteries


  • Lithium batteries are highly adaptable to high and low temperatures and can be used in an environment of -20°C to -60°C. After processing, they can be used in an environment of -45°C;

  • The lithium iron phosphate battery has a long life, with a cycle life of more than 2000 times. Under the same conditions, lithium iron phosphate batteries can be used for 7 to 8 years;

  • Charging is fast. Use a dedicated charger, 1.5C charge for 40 minutes to fully charge the battery;

  • Lithium iron phosphate battery is environmentally friendly, non-toxic, non-polluting, and has a wide range of raw materials.


  • The tap density of the positive electrode of lithium iron phosphate battery is small, and the density is generally about 0.8 to 1.3. Big size;

  • Poor conductivity, slow diffusion of lithium ions, and low actual specific capacity during high charge and discharge;

  • Poor low-temperature performance of lithium iron phosphate batteries;

  • Lithium iron phosphate battery has a long lifespan for a single battery, but the lifespan is shortened after forming a group.

Advantages And Disadvantages Of Lead-acid Batteries

Advantages: stable voltage, low price, simple maintenance, stable quality, and high reliability.

Disadvantages: low specific energy, short service life, frequent daily maintenance.

Battery Solar Solutions

The number of batteries can be customized according to the total load of the customer's electrical appliances, as well as the expected rainy weather, dark night and other longest use needs. The more batteries, the more stored electricity, and the greater the capacity of solar panels and systems that need to be configured. The type of battery depends on the purchaser’s needs for the product, lead-acid or lithium iron phosphate batteries.
