SW Inverter 1500TS: AC Wiring

AC Wiring Guidelines for SW Inverter 1500TS


The cables linking the GP-SW1500TS to the appliances are the AC cables. The following points must be observed for the AC Wiring:


• A branch rated over current protection at the time of installation shall be provided by others for the AC output circuit.


• Depending on the usage scenario, the AC output of the inverter may require a user installed breaker or fuse.


• For 20A branch circuit protection, additional breakers are needed for the GFCI receptacles.


• Review the safety information at the start of this manual before completing any AC wire installation steps.


• All AC Wiring must be approved for the application (RV, Marine, Residential). For RV applications, this may be solid wire in multi-conductor cables, but stranded wire is required if single conductors are used.


• All wiring must be rated to 75°C or higher.


• Do not connect the AC Output to an AC Power source (generator / shore power). Severe damage may occur and will not be covered under the warranty.


• Always use properly rated circuit breakers / fuses. Make sure all cables have a smooth bend radius and no kinks are present.


AC Wiring Table



Hard-Wire Installation


GP-SW1500TS provides the flexibility of hard-wire connection, and this function will make external control panel wiring easier.


Step 1 - Use a screwdriver to remove the cover.


Step 2. Pass the AC cable pass through the cable gland. Wire the AC cable on the terminal. Use the screwdriver to re-attach the cover.




It is advised that all the electrical installation should conform to the local electrical codes and should be carried out by a certified technician.


When the unit is feeding the internally inverted voltage, the current carrying conductors connected to the “L” and “N” terminals of the AC output will be isolated from the metal chassis of the inverter. Hence, during this condition, when the metal chassis of the inverter is connected to the earth ground, the “N” terminal of the AC output will not be grounded (bonded) to the earth ground. Under this condition, the “N” terminal of the AC output will not be a Neutral in the true sense. Do not touch this terminal as it will be at an elevated voltage (almost half the value the AC output voltage) with respect to the metal chassis / earth ground and may produce an electrical shock when touched!


When the unit is transferring power from the AC input source, the grounding condition of the “N” terminal of the AC output will be the same as the condition of the “N” terminal of the AC input source. If the AC input source is the power supplied from the utility, the “N” terminal would be a Neutral in the true sense. It will normally be bonded to the earth ground and will read almost 0 V with respect to the earth ground. In this case, touching this terminal will not be a shock hazard.


AC Output Terminals



NOTE: In case the load current over the outlet rated current, please use the hard wire terminal next to the outlets. WARNING! When using full power, it is recommended to use the wiring terminal.


WARNING! When using full power, it is recommended to use the wiring terminal.


GFCI (Ground Fault Circuit Interruption)


Compliance with UL standards requires that Go Power! test and recommend specific GFCIs for use on the AC output of the GP-SW1500TS. GFCIs shall be installed in the AC output wiring system to protect all branch circuits. A GFCI is a device that de–energizes a circuit when a current exceeds a specified value that is less than that required to open the circuit breaker. GFCIs are intended to protect people from electric shocks and are usually required in wet or damp locations. The table below lists GFCIs that have been tested and will function properly when connected to the AC output of the GP-SW1500TS.



Connecting the AC Loads


Calculate the total power consumption of the output load. Make sure that the total power consumption does not exceed the rated power. If the total power consumption is higher than the rated power of the inverter, remove the non-critical loads until the total power consumption is below the rated power.
