Just like you said ‘goodbye’ to phones which could only make calls and send messages and replaced them with Smartphones, it is about time you do the same for your inverter. If phones and tablets can run on advanced micro-processors then so can your inverter.
Say ‘Hello’ to Su-Kam’s Falcon Plus – Not an Ordinary Inverter
Unlike ordinary inverters, Su-Kam’s Falcon plus has a brain – 4th Generation Microprocessor. You’d be surprised to know that this is the same microprocessor which powers smartphones and tablets. This makes Falcon Plus a Smart Inverter!
What Can Smart Inverters do?
Owing to the advanced microprocessor, Falcon plus comes with ATC – Automatic Temperature Compensation. It can sense the outside temperature and regulate battery charging voltage automatically so that batteries get 100% charged irrespective of the temperature. This protects batteries from overcharging in high temperature and from undercharging when it is cold. It increases the life of battery by at least 6 months and reduces the water loss or water topping frequency in flooded lead acid batteries. It also brings down your electricity bill – how smart is that!
Why is Temperature Compensation Important?
To realize the importance of ATC, let’s quickly understand something about battery charging — Specific Gravity (SG) and the influence of outside temperature.
Every liquid has its SG which rises when it is cold and decreases when it is hot. For example SG of water at 0 degrees is high due to which it contracts and becomes ice. At 50 degrees SG of water is low so it expands. The same phenomena happens inside our batteries because wet batteries have liquid – sulphuric acid + water – called battery’s electrolytes.
Telling the State of Charge of Batteries by Measuring Specific Gravity
The best way to tell if a battery is charged is by measuring its specific gravity through hydrometer. Usually when you see Specific Gravity (SG) reading of 1.26 on hydrometer, it means that the battery is fully charged, on the other hand if the SG has reduced to 1.135 it indicates that the battery is only 10% charged. Inverters are programmed to give enough charge, in order to make the batteries reach the SG of approximately 1.26. However these readings apply only when the outside temperature is 25 degrees Celsius.
How Outside Temperature Affects Battery Charging and Specific Gravity
When the temperature is high, battery’s electrolyte expands as it SG reduces. In this condition it needs less final charging voltage to get charged. Why? Because the electrolyte move quickly and become great conductor of electricity when they are in expanded state. In cold temperature, the SG increases and electrolytes contract. They need more final charging voltage in such a state. It becomes very important that battery chargers sense the outside temperature and adjust the final charging voltage accordingly.
How Ordinary Inverter Charges Battery v/s How Smart Falcon Plus Charges Battery
Ordinary inverters are dumb – they can’t sense outside temperature. They are set to give a final charging voltage of 14.4v (for tubular batteries) to batteries at 25 degrees Celsius. Even when it is 40 degrees outside, ordinary inverter thinks that it is 25 and gives set current and voltage for charging. But this is dangerous because when it is as hot at 40 degrees, the battery’s electrolyte has expanded it needs less final charging voltage to get charged. In this case the final charging voltage should be 14.1v (for tubular batteries) and not 14.4v.
The way ordinary inverters charge batteries in hot weather results in overcharging of batteries. The batteries emit toxic fumes, its water evaporates, and in some extreme cases the batteries may even burst due to permanent damage to cell. Frequent overcharging of batteries also cuts short its life and increases frequency of the water topping/maintenance and your electricity bill.
In winters (or when temperature drops), the final charging voltage needs to be more to fully charge the batteries but ordinary inverters continue with their factory set 14.4v which means battery remains undercharged. After remaining undercharged for long, the battery loses the capacity to hold 100% charge, gives less backup and fails early.
Falcon plus with Automatic Temperature Compensation senses the outside temperature. It decreases the final charging voltage when it is hot and increases it when the temperature is low. You get full backup with other benefits of lower maintenance cost and longer life of battery — no matter how hot or cold it is outside.
