Lots of proven performance.  Rock solid design.

Often the best value, especially for longer runtime needs

The most popular.  Alot more base runtime included

Best unit for generators. Also great for frequency changing
Price(3) $599  $679  $899  $664

  1. Whether it includes a twistlock port for connection of PDUs, such as L5-30P
  2. Battery VAH capacity, which relates to runtime
  3. Prices as per Sept '14, subject to change
  4. Look for the 313g4tL unit for twistlock backplate
