FAQ

The HiEnergy series product is all-in-one RESS, the inverter can not work properly if only PV connect.

The "N-PE Relay Fault" will occur if the N-PE relay close fail when the system under offline status. Normally, this fault is caused by that the PE of Grid port and Backup port doesn't ground well. When "N-PE Relay Fault" occurs, electrician needs to check the grounding of PE wire on both these ports.

The CT is standard for HiEnergy series RESS products, and power meter is optional. the RESS products can only use the power meter provided by HICONICS. If this fault occurs, check it in the following order:

a) Check whether the actually installed device is a power meter. If the actual device is CT, check whether the "Feedback Source Selection" has been set as a power meter via Solarman App, and change the setting to CT;

b) If the power meter is actually installed, please refer to the user manual to check whether the wiring of power meter is correct. If the connection is correct, replace the communication cable;

c) If the fault still exists, it is recommended to replace the power meter.

This fault is easily triggered when there is current leakage of the PV system or the weather is humid. If this fault occurs, the electrician should check the system in the following order:

a) Disconnect the two strings of PV panels respectively, if the fault disappears after the disconnect, the fault is caused by the PV which is disconnected;

b) Contact the PV system engineer to check the insulation performance of the PV system;

c) If the fault persists after the PV system is disconnected, the inverter is faulty and needs to be replaced.

For single-phase inverter, PV Start Operating Voltage is 120V. For three-phase inverter, PV Start Operating Voltage is 200V.

There are 2 MPPTs for single-phase inverter, which Max. PV Input Power is 3750W.

There are also 2 MPPTs for three-phase inverter, PVA can connect 2 strings of PV panels, the orientation, angle and quantity of these two strings of PV panels should be same. PVB can connect 1 string of PV panels. The Max. PV Input Power is shown as below.

For single-phase inverter, the MPPT Voltage Range is 100~540V. For three-phase inverter, the MPPT Voltage Range is 180~950V.

For single-phase inverter, the Max. Short Circuit Current of both 2 MPPTs is 18A.

For three-phase inverter, the Max. Short Circuit Current of PVA is 30A, and the Max. Short Circuit Current of PVB is 20A.

The quantity of PV panels which can connect to the HiEnergy series inverter depends on the Open Circuit Voltage and Short Circuit Current of PV panel. The accumulated Open Circuit Voltage of PV panels should be less than the Max. Voltage of inverter MPPT, and the Short Circuit Current of PV panels should be less than the Max. Short Circuit Current of inverter MPPT.

Hiconics recommand to use 6mm2 cable and 32A breaker

The use of a high-efficiency monocrystalline PERC cell of Hienergy gallum-doped silicon wafer and the selection of more reliable double-glazed module packaging ensures that the 30-year. The use of a high-efficiency monocrystalline PERC cell of Hienergy gallum-doped silicon wafer and the selection of more reliable double-glazed module packaging ensures that the 30-year.
