Battery HVD/High Voltage Disconnect/Reconnect = Enable/ 14.7 V/ 14 V Max

Regulation Limit = Not enabled

Battery Current Limit = Amp Hour Battery Rating (< Max allowable charge current) for PS‐MPPT only

Load Settings (where applicable for controller models which include LVD settings): Low Voltage

Disconnect (LVD) = 12.5 V

Low Voltage Reconnect (LVR) = 13 V Delay

Before LVD = 1 minute

Load Current Compensation .005 Ω (V/A) (reduces LVD Voltage based on size of load: 0.005 suggested)

HVD/High Voltage Disconnect/Reconnect: Enable/ 15 V/ 14 V (Load HVD)

Note:

Many lithium batteries include a BMS that can implement an internal battery disconnect in the event of a deep discharge or

high voltages in order to prevent permanent damage to the battery chemistry. It is important that proper low voltage load

disconnect settings and charge settings are used to prevent this from occurring during discharging and charging. Damage to the

controller due to a battery disconnect during charging is typically not covered under warranty. Incidental damage to loads is

also not covered under warranty. Adjustments to these controller settings (raising the LVD setting, lowering the

Absorption/Float voltages or shortening the Absorption time settings) or changing system parameters should be considered.

For more information regarding settings adjustments please contact Morningstar at support@morningstarcorp.com.

Battery Charge LED Indications (Not intended for accurate SoC measurement):

LED G –> G/Y 75%+ = 13.3 V

LED G/Y –> Y 50% ‐ 74% = 13.1 V LED

Y –> Y/R 25% ‐ 49% = 12.9 V

LED Y/R –> R 10% or below = 12.7 V
