3 Product Introduction
3.1 Product Naming Rules
The models involved are as follows: GW100K-HT GW110K-HT GW120K-HT GW136K-HTH
Model Description (taking GW100K-HT as an example): 1. GW - abbreviation for company name 2. 100K - rated output power 3. HT - model code
3.2 Product Purpose
The HT series is a three-phase transformerless PV string grid-tie inverter, which is the key unit of the photovoltaic system for connecting the PV string to the grid. The inverter converts the DC power generated by the photovoltaic module into AC power that meets the parameters of the local power grid and feeds it into the power grid. The intended use of the inverter is shown in the diagram below:

If an isolation transformer is not used on the output side of the inverter to connect to the power grid, neither the PV+ nor the PV- input terminal of the inverter can be connected to the ground.

1. Disconnect the DC switch, remove the DC connector, and measure the impedance between the positive and negative poles of the DC connector and the ground. 2. If the impedance is lower than 100 kilohms, check the insulation of the PV string wiring to the earth. 3. If the impedance is higher than 100 kilohms, call the local service department. 4. Remove the AC connector and measure the impedance of the N wire to the ground wire. If higher than 10 ohms, check the AC wiring.
1. Disconnect the DC switch and check the insulation of the PV string to the earth. 2. After the check is completed, close the DC switch. 3. If the problem persists, call the local service department.
1. Disconnect the AC Breaker, remove the AC connector, measure the voltage between the live wire and the neutral wire in the connector, and confirm whether it matches the grid-tie specifications of the inverter. 2. If it does not match, check the network cable wiring. 3. If it matches, connect the AC connector and close the AC Breaker. The inverter will automatically resume grid-tie. If the problem persists, call the local service department.
1. If the grid frequency returns to normal state, the inverter will automatically resume grid-tie. 2. If the problem persists, call the local service department.
1. Disconnect the AC Breaker, remove the AC connector, measure the voltage between the live wire and the neutral wire in the connector, and confirm whether it matches the grid-tie specifications of the inverter. 2. If not, check whether the power distribution switch is closed and whether the power supply is operating correctly. 3. If it matches, connect the AC connector and close the AC Breaker; if the problem persists, call the local service department.
1. Disconnect the DC switch, remove the DC connector, and measure the PV string voltage. Confirm whether it exceeds the inverter input voltage specification. 2. If yes, reconfigure the PV string. 3. If not and the problem persists, call the local service department.

1. Disconnect the DC switch, remove the DC connector, and measure the PV string voltage. 2. Insert the DC connector, and then close the DC switch. 3. If the voltage is lower than 200V, check the PV string configuration. 4. If the voltage is higher than 200V and there is still no display, call the local service department.

Note: When the sunlight is insufficient, the photovoltaic inverter may start up frequently. This is caused by insufficient PV string power and will not cause damage to the inverter.

Interpretation of overvoltage levels: Overvoltage level I: Connect the product to a circuit with measures to limit instantaneous overvoltage to a relatively low level. Overvoltage level II: Energy-consuming equipment powered by fixed power distribution devices.
Such equipment includes appliances, portable tools and other household and similar loads. If there are special requirements for the reliability and applicability of such equipment, overvoltage level III shall be adopted. Overvoltage level III: The reliability and applicability of equipment in fixed power distribution installations must meet special requirements, including switching appliances in fixed power distribution devices and industrial equipment permanently connected to fixed power distribution devices. Overvoltage level IV: The equipment used in the power supply of the power distribution device, including measuring instruments and prepositioned overcurrent protection equipment, etc.

Interpretation of humid places

Environmental Parameters Temperature range Humidity range

Level 4K2 -33°C~+40 15% to 100%

4K4H -20°C~+55 4% to 100%

Interpretation of environmental levels: Outdoor inverter: The ambient air temperature range is -25°C~+60, suitable for pollution level 3 environment; Indoor type II inverter: The ambient air temperature range is -25°C~+40, suitable for pollution
level 3 environment; Indoor type I inverter: The ambient air temperature range is 0°C~+40, suitable for pollution
level 2 environment;
Interpretation of pollution levels Pollution level 1: No pollution or only dry non-conductive pollution; Pollution level 2: Usually there is only non-conductive pollution, but there may be temporary
conductive pollution caused by condensation; Pollution level 3: There is conductive pollution, or non-conductive pollution becomes conductive
pollution due to condensation; Pollution level 4: There is persistent conductive pollution, such as pollution caused by conduc-
tive dust or rain and snow.

8 Product Maintenance
Regular maintenance of the inverter will ensure its service life and best efficiency. Note: Before carrying out any maintenance, turn off the AC circuit breaker, disconnect the DC circuit breaker, and wait 5 minutes until the residual voltage is released.
8.1 Clean Fan
The external fan of the HT series inverter needs to be cleaned with a vacuum cleaner every year. Remove the fan and give it a thorough clean. 1. Turn off the AC circuit breaker first, and then turn off the DC switch; 2. Wait 5 minutes until the residual voltage is released and the fan stops running; 3. Remove the fan net;
Use a screwdriver to loosen the fan bracket Carefully disassemble the fan net and fan (because the internal circuit of the fan is still connected, do not pull out a single fan) as shown in the diagram below; 4. Use a soft brush, cloth or compressed air for cleaning; tighten the screws.
Fan pullout hole
8.2 DC Switch Check
In normal use, the DC switch requires no maintenance. Although not strictly necessary, we still recommend you to: · check the DC switch regularly: · turn the DC switch on and off 10 times a year. Operating the switch regularly can clean up the device and extend its service life. Note: Turn off the AC breaker first, and then turn off the DC switch.
32

Startup sequence 1. Turn the circuit breaker on the AC side to the "ON" position; 2. Turn the DC switch of the inverter to the "ON" position. Shutdown sequence 1. Turn the circuit breaker on the AC side to the "OFF" position; 2. Turn the DC switch of the inverter to the "OFF" position.
If the startup and shutdown sequences given above are not followed strictly, the inverter may be damaged.
8.3 Electrical Connection Check
1. Check whether the cable connection is loose; 2. Check whether the grounding cable is reliably grounded; 3. Check whether the waterproof covers for RS485, WiFi and other ports are sealed correctly. Note: The maintenance cycle is once every six months.
