MPPT QUICK START PROCEDURE

10. Slowly increase PS2 until the battery current starts

to decrease below 1A. The battery voltage is now

approaching the absorption voltage. The timer will

start if not already started from a low light condition.

11. When the timer has elapsed, the LTC4013 will switch

to float mode and the charge current will drop to near

0A until the battery voltage is reduced below the float

voltage.

12. Whendone,turnoffanddisconnectallloadsandpower
