Why can Honda hsaf 6500 generator not be connected to house wiring?

Answer 1

The Honda HSAF 6500 can be connected to the house wiring, There are however a few considerations to make. The HSAF 6500 has no AVR (Automatic Voltage Regulator) so the output is not suitable for sensitive equipment without some sort of "Smoothing". Most electronic equipment can deal with the problem of "bad" power supply as they have power supplies (or power converters) that modify the incoming power to what the unit will require ( Mostly DC) anyway. There is a side effect though, Most of these power supplies are "Switching Power Supplies" that are designed to accept a smooth sinusoidal wave of constant voltage and anything other than that will eventually do damage to the circuitry in the power supply. "Old" type Transformer power supplies with large capacitors are less vulnerable to this type of "Bad" input voltage. The best would be, if in doubt, to put an AVR or UPS before the equipment you wish to protect. The UPS should be an online UPS type. Induction loads such as heaters, ovens, motors, lighting etc would be fine and are less susceptible to "bad" input voltage supply. The most important though is to make sure two things never happen, 1: Utility (Eskom) power and the generator power Never meet. 2: Total Load should not exceed 80% Max Rated Power (5.5KW for the HSAL 6500)
