On a 2022 Transit with dual 250 amp alternators, the specs show vehicle amp draw at highway speeds of 100 amps, at idle 90. At idle, 1 alternator is about 176 amps and at 4000 rpm about 240 amps. Could the dual alternators handle 2 Buck Boost 100s if set at 75 each, total 150 amps? With 100 for the vehicle, that would total 250 or 50% total capacity. Thank you.
Have you any idea what the alternators can deliver at idle? And will you spend a lot of time idling?
Thank you for responding. The dual 250 alternators will each produce about 176 amps at regular idle, so base idle for both is 352 total amps. Alternators are rated at 60% capacity for continuous use, or 300 max draw continuous use. Vehicle is 100, so max draw to charger is 200. So I am thinking two buck boost 100s each set identical at 75 amps each max, or 150 total. That will give me 150 for the charge, 100 for the vehicle, total amp draw 250, which is under the 60% max draw of 300 for continuous use even at idle. The documents say that buck boost can be run in parallel. It seems like it works on paper.
Should work OK.
Thank you. I am not finding any info to the contrary.
