• In an Off-Grid operation where Sunny Island is a grid-forming device (not

synchronized to the grid or generator), the charging setpoint received from

the external BMS is automatically reduced by 1 V. This is a protective measure

implemented in Sunny Island to prevent unintended overcharging under high

dynamic conditions (sudden changes in PV and load).

• SMA brand Sunny Charge Controllers are not approved for lithium batteries and

therefore must not be used with Discover Lithium batteries.

4.4 Battery Protection – Off-grid

The Sunny Island system's operation and battery protection depend on the battery's

state of charge (SOC). In off-grid operation, the Battery Protection mode prevents

the battery from a deep discharge due to low energy supply, preventing total

system failure and damage to the battery. If the battery's SOC falls below threshold

settings (Setting: #223) (Web: Battery > Protection mode), the Battery Protection

mode is activated, and the Sunny Island switches to either standby mode or off. The

Discover Battery BMS reports SOC to Sunny Island through LYNK II Gateway but

does not override the threshold settings. Refer to the relevant Sunny Island Manual

for how to use and set up Battery Protection.

The options for increased self-consumption depend on the battery SOC and the

availability of PV energy. To use the battery optimally, adjust the depth of discharge

of the battery based on location and season (Setting: #262) (Web: Battery > Areas of

application > Season operation active). The Discover Battery BMS reports SOC to

Sunny Island through LYNK II Gateway but does not override the threshold settings.

Refer to the relevant Sunny Island Manual for how to use and set up threshold

settings. Self-consumption adjustments are not available on the 4548-US and 6048-

US models.

• Self-consumption Battery Protection adjustments are unavailable on Sunny Island

4548-US and 6048-US models.
