Solar Battery
Description
The tall tubular solar battery is the highest performing solar battery in the market. The core features of the 
solar battery are high surface carbon, micropores woven gauntlet, special grade PE separator, and 
advanced paste formulation. The improved discharge performance is mainly due to the presence of high 
surface carbon. It leads to not only high capacity and excellent life cycle performance but also improves the 
active material utilization for better performance of the electrodes.Onesun uses premium technology and 
high-grade materials in 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 inverters. 
Our main purpose in introducing such batteries is to provide an eco-friendly environment and save fuel. To 
providing long life to batteries, we basically made strong and thick plates to avoid corrosion. It has an 
exclusive deep cycle high-density plate technology that gives higher back-up than any other batteries of 
the same class range.
Tubular Solar Battery - USP's Explosion & Fire Risk
• Advanced High Surface Carbon for enhanced • Avoid short circuit and loose connections.
Performance • Authorized personnel shall carry out 
• replacement of batteries.Lowest capacity decay over storage (Self 
Discharge) • Do not store battery in places of high 
temperature and humidity.
• High purity spine and grid alloy for ultra-low 
maintenance
• Optimized negative paste receipt for fast 
charge acceptance
•  Leak proof vent plug design
Solar PCU
Key Features
• Operate on both Solar Power as well as Grid Power. 
• It is integrated with an in-built fully regulated 50Amp/70Amp PWM Solar Charge Controller for 
maximum Solar Power utilization. 
• Smart Solar Selection with three different saving modes. 
• It is designed to give you maximum benefit from solar energy and minimize your electricity bill 
drastically. 
• Highly ecient battery charging from solar energy as a result you will get non-stop power, save 
money, save electricity and protect the environment. 
• Advanced ARM Cortex technology for absolute stability and 100% pure sine wave output. 
• User-friendly LCD for the display of the mode of operation and all parameters. 
• Dual Mode of working: UPS and Normal 
• UPS Mode: Fast switching, Input operating range from 180V to 260V. 
• Normal Mode: Wide Input operating range from 100V to 290V. 
• Dual Solar Mode: Hybrid and PCU Mode 
• Hybrid Mode: Intelligent battery charging through Solar Power and Grid Power. 
• PCU Mode: Charge sharing and ability to run a load with solar and battery hence saving grid power 
and utilizing maximum solar power to minimize the electricity bill. 
# If solar is available and battery declared as full charged, then Mains will automatic cut till battery 
discharge upto pre-deined level in PCU mode.
