The Luminous 220Ah Invelast (ILST 25044) is a heavy-duty tall tubular battery specifically designed for long and frequent power outages. As part of the Invelast series, it is engineered with thicker plates and a larger electrolyte volume to provide superior backup performance and faster charging.
The Luminous 220Ah Invelast is built for high-demand environments. Its Tall Tubular technology ensures that it can withstand deep discharge cycles better than standard flat-plate batteries. This makes it a perfect choice for homes and offices that run heavy appliances like air conditioners, washing machines, and water pumps through high-capacity inverters.
High-Load Homes: Supports entire households including lighting, fans, TVs, and kitchen appliances.
Commercial Backup: Ideal for shops, offices, and small clinics requiring uninterrupted power.
Large Inverter Systems: Works exceptionally well in 24V or 48V configurations (2 or 4 batteries) for 3.5kVA to 10kVA inverter systems.
Extra-Long Backup: The 220Ah capacity offers significantly longer runtimes compared to standard 150Ah or 200Ah models.
Hadi High-Pressure Casting: Constructed using advanced high-pressure casting machines, ensuring a void-free, uniform grain structure for extreme durability.
Low Maintenance: Features high-quality vent plugs with water level indicators, making it easy to monitor and maintain electrolyte levels.
Faster Recharging: Designed to accept high charging currents, allowing the battery to reach full capacity quickly between power cuts.
Spill-Proof Design: Comes with a leak-resistant sealed plastic housing for enhanced safety in indoor environments.
