High Capacity Battery

Looking for more power?  The EnergyCell XLC battery system is an ideal solution for today's demanding off-grid, self-consumption or backup applications requiring larger energy storage.

The EnergyCell XLC battery system has a time-saving modular design. The integrated cabinet offers a cost effective solution for end- users, saving over 40% of installation time compared to a traditional battery bank. Proven lead-acid VRLA technology, combined with enhanced carbon additives, make it one of the safest and most efficient batteries in the market.

The XLC’s pioneering lead-acid technology incorporates an added carbon additive to the negative active material (NAM), enhanced separators and anti-corrosion grid design delivering a dramatic improvement in service life. 3800 cycles at 50% depth of discharge, and a 17 year standby life make this system a great value.  Optimized for use with OutBack Power conversion equipment and OPTICS RE to provide real-time access to critical battery performance data.


  • Ideal for high capacity energy demands in off-grid, self-consumption, or emergency backup applications
  • 3800 cycles @ 50% DoD at 25°C
  • 17 year standby life at 25°C
  • Integrated cabinet with modular racking assembly, interconnecting busbars, and terminal covers saves on installation time
  • 10 year standard full replacement warranty if used with Outback equipment (2 Year Warranty if installed with non-Outback equipment)
