3.6.4 CT/Meter Connection
To measure the power imported from and exported to the grid, a pair of CTs or one triphase meter must be installed at the service entry point in or near the main service panel. We standardly supply 2 CT for one inverter.

CT Port Pin definition The CT interface for 2 CTs connection is an RJ45 port ,We have made an RJ45 plug on those 2 CTs in advance, so you can connect it to the port directly.

Please refer to the connection diagram for the correct positions of CTs and clamp

the 2 CTs on the L1 and L2 wires at the service entry point in the main service panel.

CT1(label L1) should go to L1 and CT2(label L2) should go to L2. The arrow on the CT

is pointing to the inverter.(*** Incorrectly install CT will cause The Display to show

incorrect informations and features of the inverter will not function correctly) If the

CT are in a wrong direction, there is an option you can change the direction of the

CT on your inverter call: CT Direction Reversed (Only for Direction not CT1 or CT2

Placement) in Advanced Tab. You would not need to go change it physically.

When the generator is started, all the loads connected to EPS will be supplied by the generator. Meanwhile the battery will be charged.
The pass-through relay on the generator port is 90A. When the generator is on, please ensure the total load and charge current will not exceed 90A.
The generator start signal shall be connected to the COM board GEN Nominal Open( NO1 and CO1), or Nominal Close(NC1 and NO1) port, if users want to start generator remotely.

It depends on the Bat operating mode setting, The system will use either battery SOC or battery voltage to determine whether the system needs to start or stop the generator.
Generator Start Conditions When utility fails and -When battery is discharged to cut-off settings or there is force charge request from battery. or when the battery voltage or SOC is lower than the Generator Charge start Volt/SOC settings,
Generator Stop Conditions when battery voltage or SOC is higher than Charge end Volt/SOC settings value.

3.8 AC Coupling Installation Connection

The inverter supports AC coupling connection with the existing grid- interactive solar system. The existing solar system is connected to the inverter’s GEN port.

After AC couple function enabled: When the Grid is on, the GEN terminal is connected to the grid terminal inside the inverter. In this case the hybrid inverter will bypass the interactive inverter AC to the grid and EPS.

When grid is off, The GEN terminal is connected to the EPS terminal inside the inverter. In this case, the loads will be first supplied by solar power. If solar panels are generating more power than load consumption, the excess solar power will be stored to the battery. When solar power exceeds the sum of load power and max battery charging power, e.g. when battery is nearly full. The inverter will signal the grid interactive inverter to reduce power via the frequency shifting power reduction mechanism, thus to maintain the balance of generation and consumption of the micro grid system.

Users need to enable AC coupling function when they connect existing on grid system to GEN terminal
Start SOC(%): The SOC at which the AC coupled inverters are turned on when in off-grid mode. 50%~70% recommended
End SOC(%): The SOC at which the AC coupled inverters are shut down when in off-grid mode. 90% recommended
When On-Grid and Export to Grid enabled, the AC-coupled inverter will always be on, and it will sell any extra power back to the grid. Ensure you are allowed to sell power to your utility provider. When export to Grid is disabled, the AC-coupled inverter will stay at off mode and could not work at on-grid mode to sell power.

3.9 Parallel System Connection

3.9.1 Connection for paralleling system

The hybrid inverter supports parallel connection to expand power and energy capacity to suit different using

scenarios. Up to 10 units can be paralleled to reach a capacity of 120kW. Wiring diagram is as below, The manual

bypass switch connect loads to EPS panel for default. When inverters fail, users can switch the loads to utility.

The inverter has different working modes and functions to meet customers’ various demands. The working modes and functions are as below.
4.1.1 Self-usage Mode (Default)
In this mode, the priority order of load supply sources is Solar>Battery>Grid. The priority order of solar power usage is Load>Battery>Grid. Application Scenarios Self consumption mode will increase the self consumption rate of solar power and reduce the energy bill significantly Related Settings Effective when Charge Priority , AC Charge, and Forced discharge are disabled Example

Smart Load: This function is to make the Gen input connection point as an load connection point, if you enable it, inverter will supply power to this load when the battery SOC and PV power is above a user setup value. e.g. Smart load start SOC=90%, Smart load end SOC=85%, Start PV power=300W, it means: When the PV power exceeds 300W, and the battery system SOC gets to 90%, the Smart Load Port will switch on automatically to supply the load which is connected on this side. When the battery reaches SOC<85% or PV power<300w, the Smart Load Port switch off automatically.
Note: If you enable the Smart load function, it’s forbidden to connect the generator at the same time, otherwise the device will be damaged!

Standby: Is for users to set the inverter to normal status or to standby status. In standby status, the inverter will stop any charging or discharging operations, as well as solar-feed-in.

Restart inverter: Restart the system, please note the power maybe interrupted when restarted.
Export to Grid: Is for users to set a zero export function. If exporting solar power is not allowed, users need to disable the “Export to Grid” option. If users’ utility meter is tripped with even a little solar export, “Zero export” can be enabled Thus the export detection and adjustment will take place every 20mS, which will effectively avoid any solar power being exported. If export is allowed, users can enable “Export to Grid” and set a maximum allowable export limit in “Max Export to Grid(kw)”.

Meter type: Please select it according to the meter that’s to be installed.
Charge last: When users want to us solar power in the order of loads — grid export — battery charging.

Offgrid output: It is for users to set if the inverter provides backup power or not when the grid is lost. If users want the load to be seamlessly transferred to the inverter backup power, “Seamless switch” must be enabled. If customers don’t have a battery installed yet, but still wish to have inverter backup power with only solar panels connected, “PV Grid Off” can be enabled to use solar power to supply load when the grid fails or load-shedding happens. Micro-grid: only needs to be set when the generator is connected to the inverter’s grid port. With this option enabled, the inverter will use AC power to charge the battery and won’t export any power through the grid port if AC power is present at the inverter’s grid port.
CT direction reversed: If the CTs are in a wrong direction which will cause the display to show incorrect information and features of the inverter will not function correctly, the installer can modify it by selecting it(only for direction not CT 1 or CT 2 placement), there is no need to reconnect the CTs and no need to go change it physically, in the order of loads–grid export–battery charging.
