Deep Cycle Batteries and Battery Monitoring

 

Batteries for remote, standalone, off-grid or backup-up renewable energy systems 

 

Batteries are the key components in many applications and are very widely used in solar, wind or hyrdo power systems. The stored energy can be used to run household appliances at night or during the day and can be discharged rapidly to provide more power than the charging source itself can provide, so pumps or motors can be run from time to time.

The most commonly used types of battery are:

AGM Batteries

GEL Batteries

Lead Acid Batteries

Lithium Ion Batteries

 Typical battery voltages are: 2V,4V,6V and 12V

Batteries require proper maintenance and can fail prematurely if not well looked after.  Deciding on the "best" battery for your requirements requires careful consideration.  The most important aspect of buying any battery is DEPTH OF CHARGING CYCLE.

There are two main types of battery: SHALLOW CYCLE BATTERY and DEEP CYCLE BATTERY

What is the difference between the two battery types?

SHALLOW CYCLE BATTERIES are typically car batteries. These batteries are designed to provide a very high current for a short period of time; such as starting your car.  However, they cannot withstand repeated deep discharging - below 20% - and therefore are not suitable for use with solar PV systems.

DEEP CYCLE BATTERIES are designed to be repeatedly charged and discharged by as much as 80%. Having said that, if these batteries are shallow cycled - not discharged below 50% of capacity - then they will have an even longer life. 

A typical Lead Acid battery contains liquid acid in cells that are sealed.  AGM and GEL batteries are known as SEALED Lead Acid batteries. Thus, both AGM and GEL batteries are better known as "maintenance free" batteries. The size of a battery bank is determined by the storage capacity required. Battery capacity is determined by the amount of electrical energy the battery can deliver over a certain period of time and is measured in Ampere hours (Ah) when discharged at a uniform rate over a given period of time.
