Sri Lanka's power situation is still dire, with outages lasting 2 to 4 hours in cities and 8 hours or longer in small towns and villages. Because of this, managing everyday life becomes challenging, making the installation of power backups necessary.
Although people opt to install an Inverter-Battery system, they hardly know how to choose the best Inverter-Battery for home use in Sri Lanka with the price and which is the best brand for Inverter with battery for home.
With advancements in technology, people now get the option to either buy an Inverter and a battery separately as most inverters work well with all types of batteries or buy an inverter combo with a battery for home use. The inverter and battery combo from the same brand is more efficient as they get checked regularly by the manufacturers’ engineers and hence last longer.
Now the question arises is which brand has the best inverter with a battery for home and how to choose one. To help you with the process we have prepared a list so that you can choose the best inverter with a battery for your home without any difficulties.
Best Inverters for Homes with Battery in Sri Lanka2023
Lento manufactures both LKVA sine wave inverter and HKVA Static UPS and Inverter.
LKVA Inverters- Lento pioneered pure Sine wave technology in its inverters, UPS and power supplies. Our Sine wave inverters output stable frequency and voltage, mimicking mains power supply, making it perfectly suitable to power expensive equipment, especially inductive loads that do not work well on square waves.
HKVA Static UPS and Inverters - Most appliances like CFL, fans, and motor-based equipment like air conditioners and pump sets are designed to work on 50 Hz sine waves. Running such types of equipment on unregulated quasi sine wave-square wave-based inverters poses a risk as regards performance and durability. Lento DSP sine wave Static UPS and inverters are designed to provide stable 50 Hz sine wave irrespective of load and battery voltage, making them the most suitable for inductive, capacitive and non-resistive loads. Importantly, our inverters and UPS are designed to deliver instantaneous high current during start-up, especially in the case of air conditioners and refrigerators, with safety cut out when battery voltage goes lower than a specified point to avoid brownouts and burning of motors.
It also manufactures DSP Sine Wave 3 Phase Inverter & ALBS Series. The DSP sine wave online UPS feature a wealth of advanced features. Designed for use with expensive critical electronics instrumentation, these UPS systems have a host of safety controls to ensure your devices are always protected. Lento DSP online UPS performs very well in case of mains failure, sensing of voltage fluctuations and automatic switchover, lighting guard, electrostatic protection, overvoltage and overload protection, short circuit protection and low battery protection. Lento DSP UPS is configured to be always active when power fails. At the same time, the batteries are kept constantly charged through a monitoring circuit to ensure their longevity. DSP sine wave online UPS are preferred especially when they are Lento with guaranteed frequency and voltage control along with inbuilt protection features.
Lento offers a wide range of batteries too-
Lead Acid Tubular batteries- Lento uses premium technology and high-grade materials in these lead acid tubular batteries to deliver maximum power for extended durations and have an appreciably longer life span. These batteries are specifically suitable for powering up UPS and inverters.
Sealed Maintenance-Free Batteries - Lento sealed maintenance-free batteries are the perfect solution when you want batteries that last for a long time and perform consistently throughout their life.
7AH /12AH /42Ah | 65Ah
80Ah | 100Ah
120Ah | 150Ah /200Ah
Automotive battery - An automotive battery is a rechargeable battery that supplies electrical current to a motor vehicle. Its main purpose is to feed the starter, which starts the engine. Once the engine is running, power for the car’s electrical systems is supplied by the alternator. Typically, starting discharges less than three per cent of the battery capacity. SLI (Starting, Lighting and Ignition) batteries are designed to release a high burst of current and then be quickly recharged. They are not designed for deep discharge, and a full discharge can reduce the battery’s lifespan.
32Ah to 200Ah
UNIQUE Lead Acid Tubular Batteries- UNIQUE lead acid tubular batteries by Lento, use premium technology and high-grade materials to deliver maximum power for longer periods. They contain tubular positive plates and pasted negative plates and are acid-resistant polyester gauntlets.

Frequently Asked Questions-
Q. Do inverter dealers sell inverter batteries as well?
Yes, dealers usually sell inverters with batteries.
Q. Can I purchase an inverter from one brand and an inverter battery from another brand?
A widespread doubt but a completely valid one. Yes, you can purchase an inverter from one brand and a battery from another. But please ensure that both are high-quality appliances and are compatible. A lot of people buy high-quality inverters along with low-quality batteries. But please remember the battery is the soul of the inverter. Hence, both should be of good quality to function effectively and produce desirable results.
Q. What size inverter do I need for my home?
The total power needed will be calculated as “Power = Wattage of appliance x Quantity.” Therefore, you'll need a total power of (125×1) + (15×8) bulbs + (56×2) fans + (25×1) decoder + (85×1) = 467W
Q. How many Ah batteries do I need for home?
The battery you need will have to be powerful enough to provide the required power for at least 2 hours. As battery voltage is generally taken at 12 Volts, here is how you calculate the battery capacity. So, a battery with a capacity equal to or higher than 140 Ah will suffice for your home.
Q. What should be the capacity of the inverter for home use?
The capacity of the inverter here means that the maximum power limit demand to which it can operate and provide electricity. Ideally, inverters between 756-1000 W are best suited for homes. There are several other types of inverters based on capacity as well. You need to choose the best for your requirements.
Q. Does the inverter increase the electricity bill?
Well, an inverter stores the electricity provided by the main grid in DC form and then converts it into usable AC when the power is cut off. Hence it consumes a fair bit of electricity and an inefficient inverter can end up increasing your electricity bill.
Q. Which inverter is best for a home in India Quora?
In India, go for Lento inverters. There are lots of other inverter brands out there like Mahindra, Sukam, Luminous, Exide, Amaron, VGuardetc.. but none of them has the service network like Lento.
Q. What are the different types of batteries?
There are three types of batteries available in the market: Lead Acid, Solar Battery, and Lithium-ion Battery. Lead Acid & Solar Battery are easily available in the online and offline market. After knowing the pros and cons of both types of batteries, decide which one fits your budget and is also good for your home.
Q. Which type of battery is best for the inverter?
Tubular batteries: They are the most efficient inverter batteries and are quite popular as well. The pencil-type armoured tubular plates are designed for uninterrupted power delivery in case of long power cuts.
