SITUATION

One alternator feeding a Starter battery

and a large Service battery.

PROBLEM

The Service battery will take a very long

time to recharge due to low alternator

voltage and restrictions in how the alter-

nator current is used. The Solar panel is

diﬃcult to synchronize with the alterna-

tor. Due to these issues, the battery will

underperform and die prematurely.

SOLUTION

The SMARTPASS separates the two bat-

tery banks when the engine is oﬀ. With

the engine on, the alternator charges

the service battery with its maximum

current until it has tapered oﬀ to the

D250S Dual max level. Then the D250S

DUAL charger ﬁnalizes the charge. The

recharge time is minimized. Solar panels

are easily integrated and synchronized if

a D250S Dual is used together with the

SMARTPASS.

TIP 5

See Tip 1, Tip 2 and Tip 4

Wires that are connected to both

SMARTPASS and D250S DUAL should

be connected to SMARTPASS.
