Is this the amp-setting you requested, or is this an actual amp measurement you took? That's quite a conservative setting for your 900w unit.
Does anyone know where to adjust the amp settings up/down on these 900w units? I've decided to drop down the amp setting from 15A @ 48v to 11A, which is about 25%+ further "de-rating" of the spec max.
Btw, @ 48v w/max spec amps of 15A this is only 720w, so it seems this 900w charger is "de-rated" already??? Call it about 810w "burn rate" total by adding-in heat loss inefficiency of 87-88%. That's at least 11% under the charger's 900w rating IF it can be believed.
49v @ 11A is about 540w which is "de-rated" 40% from its 900w rating, so that should be super low stress on the charger, hopefully!!!
