Operating Schedule Modes

Acumen AI Modes

1. Value Stacking (DCM & EA)

The system will optimize all possible value streams, including but not limited to demand charges, energy charges, and DR programs.

2. Demand Charge Management (DCM)

The system will minimize demand charges, but energy charges may increase.

3. Energy Arbitrage (EA)

The system will minimize energy charges, but demand charges may increase.

Charge Modes

1. Charge at Full Power
   In this mode, the EMS will charge your battery at the maximum power capacity available.
2. Charge from PV Only
   The battery will charge as quickly as possible using only the power generated by your PV system. This ensures no energy is pulled from the grid for charging.
3. Charge from Export
   The battery will charge only from energy that would otherwise be exported to the grid.
4. Charge from Clipped Power
   The battery will charge as quickly as possible based on the clipped energy that is available from the PV system.

5. Charge Evenly Over Window

   The system will control the BESS to charge at a uniform rate until the battery is full. 

   • The charging rate may fluctuate due to the BESS reporting updates to SoC to non-linear conditions like calibration events or degradation.
   • If the battery couldn’t be fully charged in the interval the system will charge at the maximum rate possible.

6. Charge from PV Only (SOC Limit)

   This is a greedy mode, where the battery will get filled as fast as possible based on the charging limits and the PV power available. However, charging will be cutoff if the battery SOC reaches the SOC limit.

7. Charge at Specific Rate

   This will charge at the specified kW rate. Charging stops if the battery is full.

Discharge Modes

1. Discharge at Full Power
   The EMS will discharge the battery at maximum power.
2. Discharge against Imports
   The EMS will discharge the battery to reduce the amount of energy you need to import from the grid. It won’t charge the battery while in this mode.

3. Discharge Evenly Over Window

   The system will control the BESS to discharge at a uniform rate until the battery is empty.

   • The discharging rate may fluctuate due to the BESS reporting updates to SoC to non-linear conditions like calibration events or degradation.
   • If the battery couldn’t be fully discharged in the interval the system will discharge at the maximum rate possible.

4. Discharge at Specific Rate

   The EMS will discharge at specified kW rate.

Fixed Peak Shaving Threshold ( 4 Threshold Modes)

The EMS works to keep your energy usage below a specific demand threshold. When demand is below the threshold, the EMS may charge the battery. If demand exceeds the threshold, the EMS discharges to reduce peak demand. However, if the battery runs out of energy, peak demand cannot be reduced. If the threshold is exceeded, the EMS will continue to target the threshold for the remainder of the billing period.

Other Key Modes

1. PV Self Consumption
   This mode optimizes self-consumption of solar energy. The EMS charges the battery when solar energy is available and discharges it to minimize energy imported from the grid. The goal is to charge as much as possible from solar exports and discharge fully until no more grid imports are needed.
2. PV Self Consumption with Reserve SoC
   In this mode, the EMS charges the battery using only excess PV generation and discharges stored energy to reduce imported energy when there isn't enough solar available. The Reserve SOC is a user-defined input that sets the minimum battery level; once the battery reaches this limit, discharging stops to preserve the reserved capacity
3. Idle/Off
   In this mode, the EMS will not charge or discharge the battery. It essentially remains inactive.
