Charging from an Alternator Extract Power from a 12V Alternator to charge 24V, 36V to 48V Lithium using the alternators internal regulator Extract Power from a 24V Alternator to charge 36V to 48V Lithium using the alternators internal regulator Auto-tunes with 3 “idle modes” of Soft, Medium, Hard. Soft has significantly reduced charging at idle; whereas hard is designed to charge at the absolute maxim when solar yield is poor and engine idle is solar backup. Medium is a happy blend in between. Impossible to have a “load dump” with internal regulator alternator: If the Lithium battery being charged closes a “no charge relay”, the contained energy in Scotty reverses direction to the low side starter battery. Impossible to damage alternator from excessive load: Temperature sensor located on alternator triggers power reduction AND voltage sense reduces power instantly the alternator voltage drops below set threshold. Allows the starter battery to still charge to lead acid bulk level and so avoid damage. Happens immediately after engine start. Multihull application with twin engine alternators to one house battery source can have twin Scotty’s between them to prevent surging of loads from one engine plus keeps factory 12V system Smart Alternator Selectable for Auto-tuning Extract Power from 48V Alternator by external regulation to charge a 48V house bank up to 7,500W and at the same time extract power up to 3000W or deliver power to 12V starter battery and 12V loads up to 3000W Extract Power from 48V Alternator by external regulation to charge a 48V house bank up to 7,500W and at the same time extract power up to 3000W or deliver power to 24V starter battery and 24V loads up to 3000W Euro 6.2 compliance is achieved with energy management. This allows the starter battery to be used as an energy source when starting/idling or using “stop start”. We don’t know of any other device that supports this compliance as well as Scotty. Manufacturers like Mercedes Benz may recommend limits for DC to DC power on the primary alternator. This is done for primarily two reasons: 1) A large DC to DC with a constant load at idle may overload the alternator and 2) A large DC to DC with a constant load at idle would defeat Euro 6 standards. With Scotty AI, both situations are avoided and DC to DC only comes on at nominated RPM. Separately, the sensitive alternator voltage measurement and temperature measurement ensures the alternator is not pulled down below capacity.
