Three-Phase Power Meter For Kstar BluE ESS
Solution:
KSTAR single-phase hybrid inverters(BluE ESS)can work on three-phase grid
systems where a three-phase smart meter is adopted to monitor load consumption
on all three phases (net zero). The system can implement data-driven decisions
to control battery charge or discharge power. This solution is applicable in
three-phase home connections where there is no phase-level zero export
requirement.The overall wiring diagram is shown as below.
Meter Introduction:
The three-phase meter is designed with high precision small dimensions, simple and convenient wiring and high efÿciency for working with inverters. It integrates the measurement of all power parameters, harmonic analysis and electric energy monitoring and assessment management. At the same time, it has a variety of peripheral interface for user to choose,which is very suitable for real-time power monitoring system.
Meter & Ct Installation:
- Pull to release the retaining clip.
- Mount the Meter on the DIN track and push the retaining clip up (a clicksound indicates it is installed well).
- The current should be consistent with the direction of the arrow,which is from the inverter to the grid.
- Buckle the CT in the direction of the arrow.
Wiring Connection:
- Correct direction of CT: Inverter→Grid.
- Ensure CT and corresponding supply cable are connected to the same phase.
Incorrect connection or direction will cause incorrect data and may damage the meter.
Inverter Setting:
After wiring connection ,all the setting can be done on the inverter. It means there is no need to set the meter. Setting steps of set meter mode and zero export function are as follows:
A: Return Button Escape from current interface or function.
B: Up button: Move cursor to upside or increase value.
C: Down Button: Move cursor to downside or decrease value.
D: ENTER Button: Conÿrm the selection.Press ENTER to enter the selected menu.
Kstar System in Split Grid
Application
Instead of a common-used grid type around the world, which is originally designed and used for 230V (L – N) grid type ,there exists also SPLIT grid type(as shown in igure ) like in North America, with the grid voltage as: L1-L2 220V , L1-N or L2-N 110V. Normally, household loads consume power from 110V or 220V SPLIT grid. Therefore, it needs a solution to use the single- phase hybrid inverters in this grid system.
Solution
The smart meter is powered by 110V source (LA / LB against N),For details
refer to the following overall wring diagram: BluE ESS With SPLIT Grid.
- Current and voltage detection: CT1 and CT2 detect separated currents on L1 and L2.Voltage on each phase is detected by power cables LA and LB. Then power consumption status on each phase will be calculated.
- 110V loads: The total load power on both phases is calculated, and all controlling logic is based on the total power consumption on both phases together.
- 230V on-grid loads: Current through two CTs will be accumulated and then calculate the power consumption condition.
Meter & Ct Installation:
- Pull to release the retaining clip.
- Mount the Meter on the DIN track and push the retaining clip up (a clicksound indicates it is installed well).
- The current should be consistent with the direction of the arrow,which is from the inverter to the grid.
- Buckle the CT in the direction of the arrow.
Wiring Connection:
- Correct direction of CT: Inverter→Grid.
- Ensure CT and corresponding supply cable are connected to the same phase.
Incorrect connection or direction will cause incorrect data and may damage the meter.
Inverter Setting:
After wiring connection ,all the setting can be done on the inverter. It means
there is no need to set the meter. Setting steps of set meter mode and zero
export function are as follows:
A: Return Button Escape from current interface or function.
B: Up button: Move cursor to upside or increase value.
C: Down Button: Move cursor to downside or decrease value.
D: ENTER Button: Conÿrm the selection.Press ENTER to enter the selected menu.
