Battery Storage

With so many different types of battery storage for solar now on the market, it can be confusing to know which batteries will best suit your needs.

Some of the more popular types are AGM (absorbed glass mat) batteries, Tubular Gel batteries and Carbon batteries. However as technology continues to progress we are seeing more and more new types of batteries beginning to become available. Some newer technology batteries include Lithium, Zinc Bromide, and Saltwater.

AGM batteries

AGM  are a long lasting battery built to handle the harsh Australian weather conditions.

They use glass mat technology within the battery to absorb the acid, as opposed to standard flooded batteries where the acid is free flowing. AGM batteries are 100% sealed, non- gassing, and maintenance free.

Ideal uses for AGM batteries:

  • Small to medium off grid systems
  • Camping power
  • Projects that are budget conscious
  • Applications with medium service lives

Giant Power

With a lifespan of 1650 cycles at 30% DoD, and 12 year designed service life, AGM batteries are a very affordable option.

Tubular Gel

Tubular Gel batteries are probably the cheapest batteries on the market.

Gel batteries combine latest tubular positive plate and fixed fumed gelled electrolyte to provide deep cycle performance.They have  no vents, will not release gas during the charging process, and don’t require adding water.

Ideal uses for Tubular Gel batteries:

  • Off grid solar systems
  • hybrid solar systems
  • long life power storage

Hoppecke

The 2V Opzv batteries have a lifespan of 5500 cycles at 30% DoD.

Giant Power

Giant Power’s range of tubular gel batteries have a average lifespan of 12-15 yrs, 4500 cycles at 30% DoD, and a 20 yr chemistry life.

Carbon

Proving itself to be one of the best batteries available for projects requiring  reliable and long lasting batteries, Carbon batteries have a 20 yr designed service life. They provide high energy density and high power with a rapid charge and discharge.

They are a new type of battery where supercapacitor technology is used to prolong the life of the battery unit. Made up of highly conductive carbon material, they combine the advantages of lead acid batteries and super capacitors.

Ideal uses for Carbon batteries:

  • Applications with long service lives
  • Superior safety performance required
  • Off grid solar systems
  • Setup requires high  reliability

Gaint Power

Has an amazing lifespan of 7000 cycles at 30% DoD, 20 yr designed service life, a 7 yr battery warranty ( 3yr full replacement warranty, 48 months pro rata replacement warranty).

Lithium

Lithium Ion batteries are smaller, lighter, and store more energy than lead acid batteries, which makes them a rather attractive battery option.

The electrodes are mostly carbon or graphite based, with an organic solvent of lithium salt acting as an electrolyte.

Ideal uses of Lithium batteries:

  • Grid Connected Solar Systems
  • Where limited space is available

LG Chem

The LG Chem batteries can be cycled 6000 times at 90% DoD, with a life expectancy of over 10 yrs.

Zinc Bromide

Currently only produced by Redflow, the ZCell (Zinc bromide battery) can lay dormant for long periods at any state of charge without deteriorating. It is extremely new technology that will be available soon.

As it is charged an electrical current is sent through the battery causing the zinc to be removed from the zinc bromide and electroplated onto plastic electrodes. The opposite happens when it is discharged, the zinc is removed from the electrodes to make zinc bromide and an electrical current is produced.

Ideal uses for Zinc Bromide batteries:

  • Applications with occasional use such as holiday homes, seasonal businesses.
  • On grid solar systems
  • Off grid solar systems

Redflow ZCell

A warranty of 10yrs or 30,000 kWh’s is given on the lifespan of the ZCell battery, they are capatible of delivering 10kWh of stored energy a day. Currently the ZCell is only compatable with Victron Energy Multiplus or Redback Technologies RB4600 inverters.

Saltwater

Produced by Aquion Energy, the Aqueous Hybrid Ion batteries are uniquely designed as environmentally- friendly. They are the first and only batteries to be Cradle to Cradle certified.

Containing no heavy metals or toxic chemicals, non-flammable and non-explosive, they are considered the safest battery in the world.

Ideal uses for Saltwater batteries:

  • Residential solar systems
  • Off- grid solar systems
  • Micro grids
  • Commerical and Industrial

Aquion Aqueous Hybrid Ion

The Aquion saltwater batteries have a lifespan of 3000 cycles at 100% DoD, and a warranty of 8 yrs ( 5 years full warranty, 3 yrs pro rata)
