Inverter with Battery

With the scorching summer season in progress, it has become imperative for people to have 24*7 power backup solution. No human can survive this heat in case of power cut. Hence people need proper energy solutions/ power backup solutions to survive this summer and enjoy the fans, cooler/ ACs. Moreover, for those who can afford living in a society with 24*7 power the electricity bill will be quite high. Hence our suggestion is to install an inverter battery system comprising Loom Solar’s CAML100 Battery and Fusion5kVA Inverter.  It is light-weight with zero maintenance, and also safer to use.

Batteries are needed to store the energy generated to be used later when required. Battery costs have fallen by 80% in the last seven years and expected to fall by another 40-50% in the next five years. But it is still considered expensive in the price-sensitive Indian market. There is a lack of large-scale demand for lithium batteries in India and hence prices have not come down as rapidly as that of solar panels. Storage seems to be the only solution for the growing transmission and distribution problems in India. Some of the popularly used solar batteries in India are Loom Solar, Exide, Luminous, and Okaya. The cost of solar storage ranges between INR 6 –INR 10 per kW. In Luminous, solar batteries are designed at C10 capacity and the model starts from 20 Ah – 200 Ah, with 3 years and 5 years replacement warranty.

It is a low maintenance battery and the self-discharge is also less. Lead-acid batteries lost the plot due to their dependence on hazardous metal lead and their low energy density. You can look into buying an Inverter Battery for your home. 

Battery Backup Time

The backup time of a battery depends upon Battery storage capacity measured in Watt Hour (Wh) or Kilowatt-hour (kWh)

Batteries are rated in Ampere (I) & Voltage (V), the formula of Power = Voltage (V) * Current (I), i.e. Power = 48V * 100Ah = 5000 Watt Hour  

back up time (in hours) = Total power consumption (in Watts)/ Battery storage capacity (Watt Hour)

here, 1500 Watt / 5000 watt hour

= 3.5 hours

Generally, batteries are rated in AH and Voltage. To calculate watt-hour, you should multiple, Battery ampere * battery voltage (12 Volt).

The powder formula is (Wh) = Ampere * Voltage

For example,

150 Ah lead-acid battery and the battery voltage is 12 Volt.

The storage capacity is 150 AH * 12 Volt = 1800-Watt hour or 1.8 kWh.

The higher the watt Hour, the higher the will be backup time. Usually, a 150 Ah/ 12-volt lead-acid battery gives around 3 hours of backup on 400-watt Power consumption.

In India, 150 Ah is the bestselling rating as it can last up to 3-4 hours if you use Led light, few ceiling fans, Led Television, mobile and Laptop charging.  For a higher duration backup, one can go for the higher Ah battery.

Similarly, in Lithium battery – 100 Ah /51.2V Volt is the most selling lithium battery which has a storage capacity of 5,000-Watt-hour power. The backup time varies with a change in power consumption.

Q9. What’s the ideal inverter battery capacity of a small house?

Ans: Ideally, a normal house would need a 4 kWh system to run independently of the power grid.

Ans: The rule is,

Recommended sales panel size = 2 * Battery Capacity (Ah)

Why,

The battery has to be charged during the day when sunlight is available, i.e from morning 9 am to evening 5 pm.

Battery charging current = Battery Ah (Capacity) / Sunlight hours

Considering, the battery Ah is 150 AH,

Battery charging current = 150 Ah / 10 H = 15 amps.

2 nos. of 150 watts Luminous PV module should be installed at the rooftop for generating 15 amps charging current. 1 no. of 150-watt solar module generates nearly 8 amps at peak. Hence, a two-module of 300 watts will give 15 amps current to charge the battery.

Q11. What is the backup time of the battery?

Answer: The backup time of the battery is derived by Battery Capacity and Battery voltage.

So, if you buy a 150 Ah (ampere-hour) battery – it is a 12 V battery,

Hence

Voltage (v) * Current (I) = Power (watts)

12 V * 150 Ah = 1800 watts, considering 20% is loss during charging and discharging

Useable power = 1800 watts – 20% loss = 1440 watt 

Standard formula:

Backup time = Battery AH * 12 V * efficiency of battery / Power consumption in watts

Where,

Battery Ah = Ampere hour (capacity of the battery measured in AH)

The efficiency of battery = generally it is 80%

Example

I have a 60 Ampere hour (Ah) battery, my load is 150 watts, what will be the backup time?

Backup time: (60Ah * 12V * 0.8 efficiency) / 150 watt = 3.84 hours

Q12. What to do when the battery stops giving backup?

Answer: The solar batteries are sold with a replacement warranty of 3-5 years, so if your battery stops giving backup during the warranty period, it requires replacement. Talk to the battery manufacturer and request them to replace it.

The rule is, 

your battery must give less than 60 minutes of backup during the warranty period.

In case, the warranty period has expired, you can sell your old batteries to an authorized re-seller or the company. The old battery could also be sold to a new luminous dealer from where you are buying new batteries.

The buyback price of old batteries depends upon recyclable lead content inside is and the weight of the old battery. It is measured in Kg after removing the electrolyte,

As on May 2017, the lead price per kg is ₹ 90

Standard formula:

Battery buyback price = Dry weight of the battery * Lead price per kg

Example

I have a 100 Ampere hour (Ah) battery, how much exchange value will be given by the dealer?

Buyback price: 100Ah (battery capacity)* 27 kg (dry weight) * ₹ 90 (lead price per kg) = ₹ 2430
