The Smartest Solar UPS

iCUBE is the smartest and the most efficient solar UPS available in the market. All UPS in market waste considerable amount of energy in the form of transformer excitation current. iCUBE with its unique and intelligent solar management system is capable of preventing the transformer excitation current thereby increasing the savings.

Features Highlights

Higher solar utilization

iCUBE with its advanced algorithm prioritizes the solar charging and once the battery is fully charged the solar utilization is ensured, by evacuating the battery supported by solar to the connected load. iCUBE also prevents the unnecessary charging of the battery from the utility grid.

Battery health management

iCUBE periodically does battery equalization from solar to improve its efficiency and lifetime.

Energy monitoring at your fingerprints

Peak time mains charging inhibition

Utilities suffer extra cost for both excess usage during peak times and insufficient usage during off peak times. iCUBE’s peak time utility charging control feature is a demand response system as this allows iCUBE to shift mains energy usage to off peak durations.

Maximum Savings

iCUBE is capable of preventing the unwanted transformer excitation current which no other inverter could do. This advanced feature of iCUBE makes it the most efficient solar inverter in the market.

Deciding your iCUBE model

Prior deciding to buy your iCUBE you need to have a rough estimate of the power requirement of your home. If you love technologies and have lots of technologies running as loads in your home, it will be messy to calculate all. Also it may not be possible for your inverter to support all the loads connected. Below we give a chart of most commonly used appliances and their consumption


Appliances Watts
Lamps (Bulbs) 5-100
Lamps (CFL) 5-50
LED Lights 3-30
Tube Lights 40
Television (Plasma, LCD) 100 – 300

Usually all the appliances consumes twice the power during start up, so it safe to turn off your higher consumption devices before turning on your inverter.

Battery: The battery is considered to be the heart of an inverter, it provides its stored energy for your inverter to run the loads. Batteries are usually measured in Ampere Hour or simply AH. You have varying capacities of batteries available in market ranging from 80Ah to 220Ah, greater your rating greater will be your backup time. That is from a 200AH battery you can draw 200A current for 1 hour or 1A can be discharged for 200 hours.

Tubular batteries of C20 rating are most popular they last much longer, are highly efficient, have a higher scrap value and are of low maintenance. A well maintained tubular battery could last you up to 8 years as compared to a flat plate or lead acid battery which performs for a maximum of 5 years.

Slightly overpriced we have solar batteries of C10 rating available in market. With C10 battery of 150AH you can charge or discharge at a rate of 15A while same battery of C20 rating you can charge and discharge at a rate of 7.5A. It is recommended to go with solar batteries for solar application.
