MPPT tracking
Follows the array's maximum power point as light and heat change.

30 A at 12/24 V MPPT solar charge controller with 3-stage charging.
The Felicity Solar SCCM3024-II is an MPPT solar charge controller rated at 30 A at 12/24 V. It tracks the array's maximum power point continuously and charges in three stages — bulk, absorption and float — with a -5 mV/°C/cell temperature compensation so the charge voltage follows the battery's own temperature.
