Honda EM6500S
The Honda EM6500S is designed primarily for home use with well pumps, yet offers high power for various other purposes. It features a strong 6500 watts of power, an automatic voltage regulator, automatic idle, automatic choke, optional remote start, and a voltage selector switch. These features make it ideal for powering devices that have electric motors and require a lot of energy. This model is similar to the EM5000S; however, it definitely offers more power, which is advantageous when powering large devices.
The GX390 OHV 389 cc engine produces a 6500W max AC output and a 12V 100W DC output. Another convenient feature enables simultaneous usage of both the AC and DC outputs.
It also has electric start. This is commonly desired and highly recommended by many. Honda’s recoil starting system is not necessarily difficult; however, the electric system definitely adds ease. Like most Honda generators, it also has electronic ignition, circuit breakers, muffler, and standard warranties. Additional options include a DC charging cord, transfer switch, battery tray kit, and a remote control kit.
The EM6500S is a little heavy at 227 pounds but of course Honda equipped this giant with a 2 wheel kit for mobility. It can operate one a full 6.6 gallon tank for 5.3 hours @ rated load and 10 hours @ ½ load. This will require some refueling but it is fairly efficient for its high output. It’s also a large engine so it will be loud. It usually produces 75 dB @ rated load, so one might one to isolate it from surrounding people. In all, the EM6500S is an excellent candidate for a high powered home generator.
