General recommendations for generators in XW system
The general recommendations when choosing a generator are:
1) 120/240VAC pure sinewave output (120/208VAC will not work) 2) Unbonded neutral 3) Rated for twice the power of the inverter system 4) Preferably two-wire start if used with AGS
This is because:
1) Inverter will only qualify 120/240VAC generators (L1/L2 180 degrees out-of-phase) 2) Residential systems already bond neutral in Main Service Panel, a second bond in generator will result in dual bond (NEC violation) 3) Takes into account the battery charger plus the loads 4) 2-wire start scenario means the control circuitry is built into the generator, easier to set up for non technical individuals
