Exide Inva Plus Tubular Battery is an inverter-battery range designed for dependable power backup during extended mains interruptions.
The range covers 100Ah, 135Ah and 150Ah battery capacities at the C20 discharge rate.
Tubular plate construction provides the electrochemical architecture required for repeated battery discharge and recharge.
The range is designed for 800 cycles at 80% depth of discharge under applicable operating conditions.
Multiple battery formats are available, including lower-height configurations measuring 350 mm in height.
A taller 150Ah configuration is also available, providing the same 150Ah C20 capacity in a different physical form factor.
This gives the Inva Plus family multiple capacity and enclosure combinations for compatible inverter backup systems.
Inva Plus combines tubular battery construction, deep-discharge cycling and multiple physical configurations for compatible inverter systems.
