This is a Power TechON inverter review of the company using the 2000 watt inverter as a case study. Power TechON is also known as GoWise. The brand has a range of inverters in the market. If you are thinking of buying a Power TechON inverter or a GoWISE inverter, then please read on.
If you are looking for an above-average pure sinewave inverter and a relatively reasonable price with no frills then you have found an inverter that is ETL certified to UL468 standard. If however, you are looking for a more robust inverter, check out our list of best 2000 watt inverters or best 3000-watt inverter. Newer and more economical inverters are getting into the market every day. Personally, this would not be my first choice for a 2000 watt pure sinewave inverter.
The Power TechON PS1003 Pure Sine Wave Inverter is definitely a relatively inexpensive inverter for powering your home electronics, sensitive equipment, and power tools. Its portable nature makes it easy for you to install this unit for use in your cars, RVs, worksites, camping sites, and vessels. This inverter is capable of providing bundles of power in mobile and permanent installations, a reliable backup for power failure emergencies. There are reasons why you would want to buy this inverter brand and there are reasons why you may choose not to pick this particular model.
WHY PURE SINE WAVE INVERTER
To best suit, your power needs, the pure sine wave inverter is a more efficient choice than the modified sine wave inverter. This is because they produce clean power like utility-supplied electricity which helps to run your power demanding appliances quieter, faster, and cooler than the modified sine wave inverter. All these devices including your printer, microwave, and any other power demanding appliance, will work properly with this inverter and do not stand the risk of getting damaged or failing unexpectedly as seen in the modified sine wave inverter. However, the pure sine wave inverter is more expensive than the modified sine wave power inverter. The Power TechON inverter is one of the top-selling 2000 watt inverters on Amazon

FEATURES OF POWER TechON PS1003 PURE SINE WAVE INVERTER
With 2,000 watts of continuous power, this inverter is guaranteed to run any of your appliances and equipment within its wattage range as long as the load is not greater than 2000 Watts. It also has a surge capability of 4000W which helps to kick-start those appliances such as your microwave that require a large amount of power on startup. You need to check the maximum rating of your device before purchasing this inverter. Do not purchase this inverter if the power rating of your device exceeds the power rating of this inverter.
I did not test this inverter myself, however, I found that some readers found that it tripped off when they tried running devices above 1000 Watts. Many other buyers testified that it ran their 1500Watt and 1600 Watt power tools and Microwave. What I understand by this is that some of the specific inverters may have been faulty.
Three 120VAC Outlets
It has a total of 3 AC outlets which allows you to connect more of your equipment directly to the inverter. This has more AC outlets than most of the similar rated pure sine wave inverters. However, these outlets are not GCFI protected. This means that they do not provide a safe and convenient way of powering your devices neither do they protect you from electric shock and accidental fire outbreaks especially when you use the inverter in wet locations.
The Power TechON PS1003 inverter does not have a visual display. It does have some led indicators. You will need to read your load and battery levels with an external LCD Display which you can purchase on Amazon.
There are LED notification lights that indicate the status of the inverter at any point in time during operation.
Built-in USB port
This convenient 5V USB port allows you to conveniently power your cell phones and other modern USB-enabled devices. Most inverters feature this USB but while some are dual, this inverter has one 5VDC, 500mA USB port.
Soft Start, Low Interference Technology
The soft-start feature helps to reduce the starting current of the load and makes the startup of your appliances smoother. This is one of the benefits of this inverter and a feature that makes the inverter stand out. The hard-starting appliances connected to the inverter will start up smoother with low harmonic distortion.
Heavy duty terminals
This feature allows you to connect your batteries easily and it accommodates large electrical loads. It has large positive and negative terminal lugs to supply the high current needed for this power inverter. A separate ground lug is also provided for the safe delivery of power.
Thermostatically Controlled Cooling Fan
The two small internal fans keep the unit cool while operating under heavy loads so proper ventilation is required for reliable operation. Like the similarly rated inverters, they are thermostatically controlled which means that they only come on when the temperature rises above the normal temperature range for this inverter. The fans are ultra-quiet and will not be any disturbance to you, unlike the modified sine wave inverters.
This port allows connection directly to the remote panel accessory which gives you access to control the inverter from about 25ft. You can turn it off and on without even having to move an inch. However, this port is not wireless so you will need to connect the optional remote panel using a communications cable.
Low Voltage Shutdown
This automatically shuts the inverter down if the battery voltage drops below 10±0.5VDC, thus protecting the battery from being completely discharged.
Low Voltage Alarm
This feature alerts you whenever the battery voltage level has become discharged to 10.5±0.5VDC. It allows you to disconnect your devices before the inverter shuts down completely.
Over Voltage Shutdown
This feature shuts the inverter down automatically if the input voltage rises to more than 16±0.5VDC, to prevent devices from getting damaged.
AC Overload Protection
This feature prevents overheating and possible damage by shutting the unit down automatically if a short circuit occurs or if the loads attached to the inverter exceed the operating limits.
This feature turns the inverter off if its temperature rises above or falls below an acceptable level.
Short Circuit Protection
It helps to prevent against malfunction or system failure when there is low resistance.
COST & WARRANTY
This unit is relatively inexpensive for a pure sine wave inverter. It has a 1-year warranty plan starting from the date of purchase.
Pros of Power TechON PS1003 Pure Sine Wave Inverter
- The biggest reason for this inverter is the price. It is very economical for those who want to start in a relatively inexpensive way. It’s also good for those who just want something inexpensive for backup in their vehicles.
- It has a good number of AC output sockets and a USB Port.
- The remote switch lets you control the inverter from a convenient location, up to 25ft while the inverter itself is mounted out of sight and close to the batteries.
- ETL (UL468) Certification – Among the cheap products I reviewed, the Power TechON or GoWISE Inverter (PS1003) is one of the few that have been tested and certified to operate safely within the Standards in the USA and Canada.
Cons of Power TechON PS1003 Pure Sine Wave Inverter
- An absence of a hard-wire port means that you cannot connect directly from the inverter to your home circuit box or distribution box.
- It does not have settings that allow you to change your frequency between 50-60Hz depending on which frequency is in operation in your location. It can only be used within America as its operating frequency is 60Hz.
- A lesser number of USB ports than the other inverters on this list. This should not be a problem because you already have a good number of AC outlets.
This product on Amazon has received a fair amount of reviews from both satisfied and dissatisfied customers. Some of the customers commended the efficiency of the power supplied by this inverter and how well the inverter runs their appliances including microwaves and other hard-starting devices. However, one of the reviewers complained about the length of the wires that come with this inverter and suggested that anyone planning to purchase this inverter will do well to purchase a cable by themselves.
There are many inverters out there that are relatively inexpensive for those who are not fully dependent on their inverters. The Power TechON inverter is above average especially because it is ETL certified.
Personally, I would not buy this inverter at this price today. There are inverters from more recognized manufacturers in the market. At a point 2 -3 years ago, this inverter was one of the most cost-effective.
