What is the difference between the Kohler 18RES and the 18RESL?

Product features:

• More Powerful Performance
• Kohler's exclusive PowerBoost(TM) technology provides greater motor starting capability for large loads such as central air conditioners while still running other home appliances and electronics.
• Safer Power for Sensitive Electronics
• Many power sources can damage and degrade sensitive home electronics due to unstable power quality or high levels of total harmonic distortion (THD). KOHLER residential generators protect all of your valuable appliances and sophisticated electronics with cleaner, safe and stable power that meets strict utility requirements and IEEE standards for THD.
• Quieter Operation
• Sound enclosure maintains neighborhood solitude whether you are in self-test or full operation mode. 68 dB(A) at 7 m, similar to a typical central air conditioner.
• Faster Response
• While many competitive products can leave you in the dark for 25 seconds or more during an outage, KOHLER generators restore power in as little as 10 seconds.
• Superior five-year limited warranty included
• Easier Service and Installation
• Unlike most competitive products our engines include hydraulic valve lifters for reliable performance without routine valve adjustment or lengthy break-in requirements.
• Kohler's new easy-connection terminal block provides faster, flexible installations.
• Polymer base eliminates the need for a concrete mounting pad, reducing installation time and cost and the new 18RES(L) is designed with a hinged roof for easy service access.
• More sophisticated diagnostic self-test
• While some competitive products perform a short, reduced-speed exercise each week, KOHLER residential generators perform a 20-minute full-speed exercise cycle and self-diagnostic test each week to ensure your generator is ready to run when you need it.
• Sophisticated fault codes on Kohler's exclusive Advanced Digital Control let you know where service may be needed.
• Emissions certifications
• Meets Environmental Protection Agency (EPA) nonstationary unit requirements and California Air Resources Board (CARB)-certified for both LP vapor and natural gas (field-convertible).
• TSW is NOT Service Entrance Rated You need a fused disconnect installed before the TSW.
  

Alternator features:

• NEMA MG1 ,IEEE, and ANSI standards compliance for temperature rise and motor starting.
• Self-ventilated and dripproof construction.
• Vacuum-impregnated windings with fungus-resistant epoxy varnish for dependability and long life.
• Superior voltage waveform from a two-thirds pitch stator and skewed rotor.
• Digital voltage regulator with ±1.5% no-load to full-load regulation
• Rotating-field alternator with static exciter for excellent load response
• Skewed generator construction produces a smooth AC waveform

Engine features:

• Natural gas or LP fueled.
• Electronic engine controls for optimized fuel and spark performance.
• Four stroke, two cylinder engine.
• An electronic, isochronous governor for precise frequency regulation.
• High silicone content pistons for improved durability.
