For example, the parameters are set as follows:
P00.01 1 Terminal control
P00.06 6 Multi-speed setting
P01.18 1
P01.21 1
P05.00 1 HDI selection
P05.01 16 S1
P05.02 17 S2
P05.03 18 S3
P05.04 19 S4
P05.09 1 HDI speed terminal
P10.04 40% S1 on, 20Hz
P10.08 60% S1+S2 on, 30Hz
P10.16 80% S1+S2+S3 on, 40Hz
P10.32 100% S1+S2+S3+S4 on,50Hz

Generally, the battary voltage is around 14~10V discharging from full to emty. So 100AH*(14+10)/2V=1200VAH=1.2kWH

When the input voltage fluctuates by -15% to 10%, the MVD can run at full load, and when the input voltage fluctuates by -35% to +20%, the MVD must run at reduced amount.

IVC2, IVC3 series.

Voc is the open circuit voltage of the photovoltaic panel, and Vmp is the maximum power point voltage. When calculating, use Vmp to calculate the number of photovoltaic panels. After calculation, you need to consider that the total Voc voltage is less than the overvoltage point of GD100-PV.In the manual, there are the suitable solar panel conficuration.

GD350 needs to be equipped with a Bluetooth card, scan the QR code on the inverter, download and install INVT Workshop, and open the mobile phone Bluetooth to connect to the inverter. See the video link below for more steps.

GD350 needs to be equipped with a Wifi card, scan the QR code on the inverter, download and install INVT Workshop, and open the mobile phone Wifi to connect to the inverter hotspot. See the video link below for more steps.

Set vector 0 mode. Output power calculated by formula P = UI * cos φ * 1.732
Change P02.01 = 560kw, although it is the parameter of asynchronous motor, the synchronous machine algorithm is calculated according to the power of asynchronous motor.
Change P02.18 = 400V, and force the voltage parameter to 400V.
Change P03.24 = 110% and adjust the maximum voltage limit to 110%.
You can also change P02.28 and display parameters.
Or change P08.41 over modulation, into depth modulation, do not change until absolutely necessary, will have an impact on the wave.

This is the most common fault. Inverter three-phase output UVW phase maybe short circuit phenomenon, or external electrical equipment interference, or IGBT,IPM module is damaged.
