hi does any know if there is a neutral to ground bond in a xantrex sw 2000. i need to know because, i currently use one through a transfer switch(which i also use a generator through) which has a main breaker . which already has a neutral to ground bond.thanks in advance

Yes, there is a neutral to ground bond in the Prowatt SW 2000, the Freedom SW 2000 Inverter/Charger version bonds them when running as a inverter and opens the conection when connected to external power.
