Tonytequeenergy: The type of Battery I will be discussing about is called a Lead acid battery, which is one of the most common types of batteries we use today for backup for solar inverter. We need to also know that battery is the bedrock of every solar inverter. Where huge amounts are spent, therefore we should be much careful when we are making a choice of battery irrespective of cost to avoid double expenses . Lead acid batteries includes AGM , Gel and Wet cell batteries. These batteries had been designed to have a life span of 3-4 years for AGM and GEL batteries while WET CELL has over 4 years life span. But the lifespan of these batteries lies in the hand of the user and the installers.
Many times users complain bitterly for spending hundreds and millions of naira for batteries to beable to have uninterrupted electricity for at least a period of 3yrs but got shut off before time. Degradation of batteries shorten its life span. When a battery pack up under One year or over one year, it was because it was degraded by usage. It is always really sad when you realise as a user when the battery you with hard earn money suddenly stops performing at that early stage when you have not gotten a value of your money. Many users sometimes give up to solar inverter as unreliable and waste of resources in solving electricity problem.
Nevertheless, now we will be wondering how this problem could be solved and cause of early damage of batteries, which prevents using them up to its lifespan as designed to last by the manufacturers.
The cause of early damage of batteries are simply caused by the user and poor design of battery bank with loads by inverter installers.
The users contribute immensely to the early degradation of battery lifespan with respect to usage of battery up to 0% before turning off Their inverter. It is good to know that every lead acid batteries have been designed not to be discharged below 50% in order to sustain the lifespan of the battery up to the years it's designed to last. To maintain the lifespan of lead acid batteries it must always be discharged and maintained at 50% DOD. Using battery below the DOD( depth of discharge) will endanger the battery lifespan or shorten its lifespan.
Now I will teach you how to design a battery bank with your loads up to the hours of expectation and still maintain 50% depth of discharge of the battery bank to sustain its lifespan to enable you get the value for your money.
Okay! Remember it's very important you carry out load auditing of your house loads and hours of backup you need.These are two things to have in mind before you can get a good design.
For Instance, supposed we have The following LOADS with 12hrs expected backup while maintaining 50% of battery DOD:
1. 2 Tv set ...30w x2=60w 2. 2fans ....80w x2=160w 3. 5 lights bulbs ...5wx5=25w 4. 1 Fridge ....50wx1= 50w ............................. Grand Total =295w .............................
How do we design to determine the size of battery bank and INVERTER capacity to match up with the hours of expectation without shortening the battery life span.
Solution Total Loads= 295wats Back time = 12hours
Size of battery bank=? Inverter capacity =? Size of Solar capacity =?
To find Battery size 295w x 12hrs =3,540whr
Then we will have to Convert 3,540whr to 3,540vahr ( 1w=1va)
3,540vah /12v ( i.e 12v of battery) =294ah ( we need 294ah battery for the load )
Now, since we will not eant to shorten the lifespan of our battery The 294ah battery will power a load of 295w for 12hrs.
To maintain 50%DOD we will multiply 294ah by 2 =588ah battery
Battery comes in 100ah, 150ah,200ah,220ah etc.
Which ever battery amperage you pick as a choice will determine the number you will buy. What you need to do is to divide. Like this
588ah/100ah=5.88 approx 6 batteries of 100ah,
588ah/150ah=3.92 approx. 4 batteries of 150ah,
588ah/200ah = 2.94 approx .3 batteries.
We will also need to consider a day of autonomy that is a day of possible rainfall to be beable to still have a day backup. Therefore 588ah of our battery will be doubled and that will give 1,176ah battery.
To find Inverter capacity Load is 295w x 25% of the load =73.75% 73.75 +295=368.75 approx 369w
Converting to kva or va 369/1000=0.369/0.8( 0.8 power factor ) 0.468kva we need less than 1kva inverter
To find solar size 588ah/4hr (4hrs of sunlight a day) =147a We need 147a of solar
Other way to calculate 588ahx12v =7056wh/4hr =1,764w of solar needed.

Where huge amounts are spent, therefore we should be much careful when we are making a choice of battery irrespective of cost to avoid double expenses . Lead acid batteries includes AGM , Gel and Wet cell batteries. These batteries had been designed to have a life span of 3-4 years for AGM and GEL batteries while WET CELL has over 4 years life span. But the lifespan of these batteries lies in the hand of the user and the installers.
Many times users complain bitterly for spending hundreds and millions of naira for batteries to beable to have uninterrupted electricity for at least a period of 3yrs but got shut off before time. Degradation of batteries shorten its life span. When a battery pack up under One year or over one year, it was because it was degraded by usage. It is always really sad when you realise as a user when the battery you with hard earn money suddenly stops performing at that early stage when you have not gotten a value of your money. Many users sometimes give up to solar inverter as unreliable and waste of resources in solving electricity problem.
Nevertheless, now we will be wondering how this problem could be solved and cause of early damage of batteries, which prevents using them up to its lifespan as designed to last by the manufacturers.
The cause of early damage of batteries are simply caused by the user and poor design of battery bank with loads by inverter installers.
The users contribute immensely to the early degradation of battery lifespan with respect to usage of battery up to 0% before turning off Their inverter. It is good to know that every lead acid batteries have been designed not to be discharged below 50% in order to sustain the lifespan of the battery up to the years it's designed to last. To maintain the lifespan of lead acid batteries it must always be discharged and maintained at 50% DOD. Using battery below the DOD( depth of discharge) will endanger the battery lifespan or shorten its lifespan.
Now I will teach you how to design a battery bank with your loads up to the hours of expectation and still maintain 50% depth of discharge of the battery bank to sustain its lifespan to enable you get the value for your money.
Okay! Remember it's very important you carry out load auditing of your house loads and hours of backup you need.These are two things to have in mind before you can get a good design.
For Instance, supposed we have The following LOADS with 12hrs expected backup while maintaining 50% of battery DOD:
1. 2 Tv set ...30w x2=60w 2. 2fans ....80w x2=160w 3. 5 lights bulbs ...5wx5=25w 4. 1 Fridge ....50wx1= 50w ............................. Grand Total =295w .............................
How do we design to determine the size of battery bank and INVERTER capacity to match up with the hours of expectation without shortening the battery life span.
Solution Total Loads= 295wats Back time = 12hours
Size of battery bank=? Inverter capacity =? Size of Solar capacity =?
To find Battery size 295w x 12hrs =3,540whr
Then we will have to Convert 3,540whr to 3,540vahr ( 1w=1va)
3,540vah /12v ( i.e 12v of battery) =294ah ( we need 294ah battery for the load )
Now, since we will not eant to shorten the lifespan of our battery The 294ah battery will power a load of 295w for 12hrs.
To maintain 50%DOD we will multiply 294ah by 2 =588ah battery
Battery comes in 100ah, 150ah,200ah,220ah etc.
Which ever battery amperage you pick as a choice will determine the number you will buy. What you need to do is to divide. Like this
588ah/100ah=5.88 approx 6 batteries of 100ah,
588ah/150ah=3.92 approx. 4 batteries of 150ah,
588ah/200ah = 2.94 approx .3 batteries.
We will also need to consider a day of autonomy that is a day of possible rainfall to be beable to still have a day backup. Therefore 588ah of our battery will be doubled and that will give 1,176ah battery.
To find Inverter capacity Load is 295w x 25% of the load =73.75% 73.75 +295=368.75 approx 369w
Converting to kva or va 369/1000=0.369/0.8( 0.8 power factor ) 0.468kva we need less than 1kva inverter
To find solar size 588ah/4hr (4hrs of sunlight a day) =147a We need 147a of solar
Other way to calculate 588ahx12v =7056wh/4hr =1,764w of solar needed.
