7.1 BATTERY CHARGING PROFILE CHART

Values before and after the slash correspond to 12 and 24 V systems respectively.
NOTE
BATTERY TYPE
Float Charge at 25°C:
Bulk/Absorption Charge at 25°C:
Set to 30 minutes every morning. Applied for 2 hours if the battery
voltage drops below 12.3/24.6 volts.
The term lead acid is a generic battery designation. Choose the charging profile that works best with your battery manufacturer's recommendations
*When using Lithium batteries, the controller does not recognize the system voltage automatically. You will need to enter custom parameters.

7.2 LED DISPLAY

START UP
When GP-MPPT-100/30 is connected to the battery bank, the controller will start a power up mode which takes several seconds to complete.

The green LED may flash for a few minutes after startup even if no PV is detected. This delay is to avoid erratic day/night transitions.

7.3 SWITCHING BETWEEN BATTERY BANKS

In some applications, two battery banks with different nominal voltages need charged from the same solar array. An external switch or relay
can be used to select which battery bank is charged by the controller.
GP-MPPT-100/30 automatically determines nominal system voltage at startup. If there is a large jump in battery voltage (i.e. switching from
one battery bank to another with a different nominal voltage), then the controller will detect the new nominal system voltage and reset.
WARNING: Switching must be done with an external device. Each battery bank must have a fuse or breaker. The switching
circuit must not allow the battery banks to be connected/shorted.
