5.3 System overview

ELECTRICAL CONNECTIONS

There are different system configurations possible depending on the user's requirements, existing electrical infrastructure and local regulations. The distribution box must be configured to comply to the grid operator requirements. The inverter has an integrated AC relay to disconnect all phases and Neutral from the grid in case of grid fault or grid outage. The inverter's generation and feed-in limitation functions require the use of an external measurement device to obtain grid information. There are 3 system configurations: System A: direct measurement of energy with CTs (up to 300 A) System B: measurement of energy with energy meter + CTs (default) System C: measurement of energy with directly connected energy meter

For System B, customers can choose different CTs based on the installation. The secondary current must be 5 A.
To ensure neutral continuity, the neutral of AC GRID must be connected together with the neutral of AC LOAD and must not be interrupted by switch.
If the Main Switch is used residual current protection device, it is recommended to choose type A protector for RCD with leakage current of 100mA or above (it is better to adjust according to the size of the system).
If the grounding type of the grid power distribution system requires the ground wire and the neutral wire to be connected together, a short-circuit bar needs to be used to short-circuit the neutral wire and the ground wire in the power distribution where the inverter output is connected to the grid.And circuit breakers and fuses are not allowed to be installed on the grounding wire.

Both Hard limit control and soft limit control can be used together. However, when Hard limit control is enabled, Anti-Reflux power cannot exceed the Reflux power limit. If the Reflux power exceeds the Reflux power limit, the inverter disconnects from the grid and triggers overload protection. When communication signal with the electricity meter is lost, the output power of the inverter is limited to the value of soft limit control and does not trigger fault protection. When Hard limit control is enabled, a loss of communication with the meter will trigger the inverter into a fault protection state.

5.10 Feed-in limitation function
The feed-in limitation function can be used to limit the power fed back into the grid. For this function, a power measurement device must be installed according to system A, B, or C.

Feed-in limitation: The sum of the feeding-in phases must not exceed the set power limitation value. The power of phases drawing power from the grid is disregarded here.

3-phase limit: The sum of the feed-in power of all three phases must not exceed the set power limit value. This setting is suitable for balancing metering, as is common in Germany, for example.

For the 3-phase limit setting, the current sensors must be correctly assigned to phases L1, L2 and L3 on the electricity meter!
If communication with the smart meter is interrupted, the inverter limits its output power to the set power limit value.

7.3 Energy storage modes
The HYD 5-20KTL-3PH comes with several integrated energy management modes.
7.3.1 Self-use
In the Self-use mode, the inverter will automatically charge and discharge the battery according to the following rules:
If PV generation equals the load consumption (P < 100 W), the inverter won't charge or discharge the battery
If PV generation is larger than the load consumption, the surplus power is stored in the battery
If the battery is full or at maximum charging power, the excess power will be exported to the grid

HYD 5-20KTL-3PH

OPERATION OF THE DEVICE
If the PV generation is less than the load consumption, it will discharge the battery to supply power to the load.
If PV generation plus Battery discharge power is less than the load, the inverter will import power from the grid.

HYD 5-20KTL-3PH

OPERATION OF THE DEVICE
The priority of power supply: PV, Battery, Grid The priority of power consumption: Loads, Battery, Grid

If it is not allowed to export power to the grid, an energy meter and/or CT needs to be installed, and the "feed-in limitation" function needs to be enabled.
7.3.2 Time-of-Use
With the Time-of-Use mode, the inverter can be set to charge the battery in defined intervals of time, date or weekday, depending on the State of Charge of the battery. Up to 4 rules (rule 0, 1, 2 and 3) can be set. If more than one rule is valid for any given time, the rule with the lower number is active. Each rule can be enabled or disabled.

In below example, the battery will be charged with 1 kW, if the SOC is below 70%, between 2 and 4 o'clock at night, from 22nd Dec till 21st March:

7.3.3 Timing

OPERATION OF THE DEVICE

With the Timing Mode you can define fixed times of the day to charge or discharge the battery with a certain power. Up to 4 rules (rule 0, 1, 2 and 3) can be set. If more than one rule is valid for any given time, the rule with the lower number is active. Each rule can be enabled or disabled, also charging and discharging period for a rule can be enabled separately.

In below example, the battery will be charged with 2 kW between 22 and 4 o'clock at night, and discharged with 2,5 kW between 14 and 16 o'clock:

7.3.4 Passive
The passive mode is used in systems with external energy management systems. The inverter's operation will be controlled by the external controller using the Modbus RTU protocol. Please contact SOFAR if you need the Modbus protocol definition for this device.

HYD 5-20KTL-3PH

OPERATION OF THE DEVICE 7.3.5 Peak Shaving
Used to limit the maximum power priority purchased from the grid.The maximum purchasing power can be set in this mode. When the system preferentially buys more power from the grid than the set value,The battery starts discharging and stabilizes the system power at the set value. Application: Peak Shaving Mode allows the grid to supply power to the load first. Applicable to the occasions where electricity price is charged according to electricity consumption and the occasions where the power grid is weak. In the weak grid situation, batteries start only when the load power exceeds a certain value, which reduces the maximum power of the connecting point and prolongs the battery life.
7.3.6 Off-grid
When the SOC of the battery is sufficient and can be discharged, it is preferred to use the battery in off-grid load mode (even if the power grid exists). After the battery enters the state of power loss, it will be transferred to the power grid or generator for load, and the battery will be charged.
1. AC Source Grid charge: After the battery enters the state of power loss, it is transferred to the grid to carry the load and charge the battery. DG charge: After the battery enters the state of power loss, it is transferred to the generator to carry the load and charge the battery.
2. AC Charge AC Charge: The sum of the power input to the power grid or generator after battery loss and when charging the battery.
When AC Source is set to DG charge, the generator can be started through Genset Mode in dry contact Control.

HYD 5-20KTL-3PH

OPERATION OF THE DEVICE
EODO: EPS Discharge Depth EPSbuffer: Safety Buffer Application: When the local power grid is unstable or generators are used.
7.3.7 Manual Genset
This mode activates manual recharging of the battery in the event of a grid failure via a power generator connected to AC GRID.
7.3.8 Feed-in Priority
In this mode, the PV system will prioritise the supply of power to the grid according to the set power after the loads have been satisfied, and will only charge the batteries when the grid supply target has been reached. Users need to pre-set the value of power they wish to deliver to the grid, and the system will intelligently allocate power accordingly. When the PV power generation is sufficient, the system will first protect the load power consumption, and the remaining power will be prioritised to meet the set grid power demand. If the actual power generation exceeds the set value, the excess will be charged for the battery; if the power generation is less than the set value, all the remaining power will be delivered to the grid, and the battery will not be charged at this time. When the PV power generation is insufficient, the system will be supplemented by the battery to meet the load power consumption gap. In this state, the inverter will not deliver any power to the grid, ensuring that local power demand is prioritised.
