GD170 is an economical solar pump controller newly launched by INVT. Compared with GD100PV, some advanced functions are missing, such as analog quantity, switch quantity and so on. .
Yes, you need to purchase QH100 automatic switching module.
If there is no automatic switching module, it is not recommended to input the grid power and photovoltaic power in the same time. Cause there is a voltage difference between photovoltaic and grid, the equipment will be impacted and the inverter may be damaged.
1. If the pump is single phase, remove the capacitors as the Q2.
2. If the pump running direction is reverse, reverse UW cable.
3. SetP02.01~P02.05 as the pump nameplate.
4. The driver powerrating is lower, suggest to replace a bigger one.
-1.GD100-PV by default setting will run automatically in 10s delay time after power-on. Within 10s of the keyboard flashing, press the JOG key on the keyboard to immediately stop the automatic running. Users can set the parameters according to their needs. Power on again will resume automatic startup.
-2.In any case, press the STOP button on the keyboard, the machine will stop running.
It is used in the power range below 2.2kW. When the photovoltaic panel quantity is less, the DC voltage is not enough to make the inverter work. The boost module can raise the photovoltaic input voltage to the inverter working voltage, reducing the photovoltaic panel quantity and reducing system costs.
GD100-PV needs to switch to the AC mode when using the grid input. You can short-connect the S1 and COM terminals or set P15.32=1 to switch to the AC mode. After switching successfully, the keyboard will flash 50.00.When it in the solar mode, the keyboard will flashes
How to adjust the time:
P15.24 can be adjusted appropriately to shorten the time for switching from mains to solar.
ETH failure means that the drive board has a short-circuit to ground or the current detection circuit is partially damaged.
-1. First, the inverter restores the factory settings, P00.18=1. Reset the motor parameters P02.01-P02.05.To see whether it will work.
-2. Try to replace the control board 34PIN horn cable or control board.
If the problem is still not resolved, the driver board needs to be replaced.
You can set P15.06,P15.07,P15.08,P15.09 to be larger, such as 15, 20, 25.
