Instant Savings Solistek V2.0 - 1000w Digital Ballast 277v Se/de Perfect Gift [WV398dsF]
The SolisTek ultra high-frequency SE/DE ballast now operates at 106 kHz frequency, making it one of the highest frequency ballasts available on the market. The SolisTek digital ballast for MH/HPS lamps will operate any single or double ended lamp at its optimal efficiency and is suitable for high-frequency 400V electronic horticultural lamps.
The SolisTek Ballast is a digital ballast on a software-based platform. Utilizing Japanese components and unparalleled engineering, SolisTek is able to achieve a less than 1% return rate.
SolisTek digital ballasts are equipped with:
- Ignition Control™ Sequential lamp ignition
- SenseSmart™ Pre-ignition self-diagnostic checks
- Low OUTPUT Total Harmonic Distortion (THD%)
What is SenseSmart?

SolisTek SenseSmart checks for 8 different factors using Pre-ignition self-diagnostic checks before attempting to power the lamp; this is intended for increased user safety.
SenseSmart check for:
- Open Output
- High/Low Temps
- Ignition Failure
- Thermal
- End of Lamp Life
- Overflow Current
- Over/Low Voltage
- Short Circuit
SolisTek digital ballasts complete a closed circuit between the lamp and power source. If any sort of break or inconsistency has been detected, it will not strike the lamp. The ballast will detect if the lamp is too hot to ignite, lamp compatibility issues, if there is no lamp plugged in, or if a lamp is defective or about to fail it will detect that it is not receiving enough of a signal coming back. It can even detect if there’s a short on your wiring, reflector, lighting controller, or a defective breaker on an electrical panel.
This is all apart of SolisTek's exclusive SenseSmart safety mechanism that was introduced in 2010. If it detects any sort of anomalies or disturbances it will turn off the lamp and attempt to re-strike every 90 seconds until it deems that it is safe to ignite. 99% of the time an error code is displayed (Matrix) or if the green led (standard unit) stays on without the lamp igniting it is pointing to something on the users end to troubleshoot. In the rare instance that a component goes out the ballast will disable itself to prevent anything further from happening.
What is Ignition Control?

Aside from the industry’s lowest output Total Harmonic Distortion (THD%), SolisTek ballasts also offer the industry’s only true Ignition Control staggered ignition technology.
SolisTek’s sequential lamp ignition technology will ignite your lamps one at a time based on load stability. This revolutionary technology (not a randomized startup) will actually detect the voltage and amperage frequencies of the electrical circuit and fire lamps when the load is most stable. Prevent surges and spikes in your electrical environment and stop overloading breakers. When you power multiple SolisTek ballasts, the electrical draw is controlled by the internal software, maximizing electrical efficiency.
SolisTek digital ballasts are the only ballast capable of this technology.
What is Total Harmonic Distortion (THD)?

Solid-state electronics don’t behave anything like the traditional magnetic core and coil ballasts. Voltage requirements, starting sequences and high frequency have all changed as well. Advancements in HID electronic ballast power supplies have caused new distortions in these lighting systems that weren’t present before. These distortions, while invisible to human eyes, contribute to mechanical problems such as premature lamp failure and excessive stress on electronic components.
When you put different waveform distortions together in a power supply, you get a new reference called Total Harmonic Distortion (THD). THD in the power system can distort voltages and overload equipment. It’s important to not only understand harmonics, but also how the electrical and power system reacts to the harmonics.
The THD, of a digital lighting system signal, is a measurement of the THD present, bulb, ballast, etc., and is defined as the ratio of the sum of the powers of all harmonic components to the power of the fundamental frequency. The lamps waveforms, power current, and the operating frequency are influenced by lamp, ballast type, power conditions, lighting controls, and temperature.
Lesser THD allows the components in digital lighting system to produce a higher quality digital signal by reducing harmonic distortions that are added by the ballast. A THD rating of less than one percent is considered to be the high end of the scale. This reference applies to high-frequency electronic ballasts which generate the THD that the lamp broadcasts. The lamp is literally broadcasting the frequency and any signal noise generated by the ballast.
All electronic ballasts have a different level of THD. Some popular e-ballasts are running from 250% to 400% THD. That level of THD is a very large, unacceptable number. These THD’s are causing massive problems for the lamp and ballast and are producing huge amounts of signal hash, which translates into poor light quality.
I don’t get it…?
If you spent thousands of dollars on a new stereo system, for example, you don’t want to hear static and distortion. The same is true with an electronically ballasted HID lighting system, except human eyes don’t see distortions of light. The rods and cones of human eyes are not equipped to register the distortions in waveforms. If the light is distorted, you are not getting the quality of light for the cost of energy being paid.
Lighting System Performance
The entire lighting system must be considered when talking about “performance” and “reliability”. The lamp and the ballast must work properly together, like a speaker and an amplifier. If there is a mismatch in lamp and ballast systems, then distortions are created and amplified. Adding a complex, high-frequency waveform to a lamp that was made for a simple one causes mechanical stresses on that lamp causing premature arc tube blackening, as well as cracks in the arc tube due to erratic arc stream performance.
There’s a THD Rating on my Electronic Ballast and the Number is Very Low…
THD in lesser quality electronic ballasts will continue to be an important factor. Electronic ballast manufacturers do list a level of THD on their products. What these listed ratings are measuring is the total harmonic distortion that travels from the ballast to the wall; what they aren’t measuring is the distortion level from the ballast to the lamp which can actually be much higher. This was a rather large oversight by the makers of electronic ballasts.
Summary
There are a wide variety of considerations to take into account when converting to the new HID digital electronics. Proper lamp and ballast combinations are essential for successful integration of these technologies. A lack of understanding these THD considerations will cost time, money and energy at the expense of the crops. Failing systems are frustrating, costly and inefficient. Take all the necessary time and precautions to buy compatible digital lamps and ballasts, with a low THD, to gain the maximum benefits.

Instructions
SolisTek Digital Lighting
PLEASE READ INSTRUCTIONS BEFORE INSTALLATION
Congratulations on your purchase of the industry’s highest quality digital lighting products. SolisTek digital ballasts are tuned and optimized for the lowest OUTPUT total harmonic distortion (THD) and matched to SolisTek Digital Lamps for maximum output and spectral balance.
Incorrect use or installation may lead to product damage or failure. Any damage caused by incorrect use or installation voids the manufacturer’s warranty. Please carefully read this manual before installing your digital ballast.
Unique Technology
- Ignition Control™: SolisTek’s Ignition Control is a software-based technology that allows one‐at‐a‐time sequential lamp ignition. No matter how many SolisTek ballasts you are running, your lights will ignite one‐at‐a‐time. By utilizing a staggered ignition, SolisTek ballasts prevent huge current draws/spikes in your electrical system and is a more efficient means of lighting your garden.
- SenseSmart™ Technology: When the ballast is powered on, SolisTek ballasts will send a mV signal through the closed circuit (between ballast and lamp), to determine a variety of different factors such as: lamp type, open/short circuits, high/low temps and thermal issues, ignition failure, overflow current, and end of lamp life.
- World’s Lowest HID OUTPUT THD%: With an input Total Harmonic Distortion (THD) value of <10% and an output THD% of <12%, SolisTek digital ballasts provide the cleanest signal for HID lamps. This provides maximum output, spectral perfection, and longevity of your equipment.
Installation
SolisTek digital ballasts can be positioned universally. The unique design of the heat sink dissipates heat away from the critical components in the ballast. If ballasts are mounted vertically to a wall, it is preferred to mount lamp output side TOP and mains BOTTOM. SolisTek digital ballasts are designed for use indoors and are sealed for damage against humidity and dust.
Avoid installing your ballasts in a high heat area, such as an attic or closed area or rooms that reach temperatures over 100°F. Do not stack ballasts on top of another. When placing ballasts, make sure to keep a distance of at least approx. 6” in between individual ballasts. Do not install in a wet area or areas prone to water.
SolisTek digital ballasts, depending on model, are compatible both on 120V and 240V power and are also generator ready. When installing your ballasts, we recommend to utilize up to 80% maximum load of your breaker capacity for electrical safety.
CONTACT A LOCAL ELECTRICIAN IF YOU HAVE ANY DOUBTS.
Lamp Connections
- Never turn on the ballast without the lamp cord and lamp installed.
- Never disconnect the lamp from a live ballast.
- Hot‐restrike: it is very important to allow your lamp to cool before attempting to reignite. It is recommended to allow 20‐30 minutes before restarting to avoid damage to the lamp.
- Ensure a snug fit when installing lamps
- Make sure the mogul socket shows no signs of damage or corrosion.
- Confirm that power has been disconnected from the ballast before attempting to change lamps.
Compatible Lamps
SolisTek digital ballasts operate both Metal Halide (MH) and High Pressure Sodium (HPS) lamps. While SolisTek digital ballasts are compatible with a majority of brand name lamps, SolisTek digital lamps are recommended. Our technical engineer’s tune and match our light systems together for optimal output and spectral balance. Using a matched SolisTek system has significant benefits over unmatched systems in terms of light quality and longevity.
- 1000W Ballast, recommended to use 1000W lamps only, or run 2 x 600W with the SolisTek splitter.
- 600W Ballast, recommended to use 600W or 400W lamps.
- Please make sure the proper wattage lamp is installed before adjusting ballast to full power or boost mode.
- SolisTek digital ballasts have soft‐start integration, ballasts ease up to full draw.
- SolisTek ballasts utilize soft‐dimming, power will ease up to full draw. It may take a few minutes for the ballast to dim from each setting. Visible dimming may not be noticeable to the human eye.
Preventing EMI
All high frequency ballasts, to a degree, will cause electromagnetic interference (EMI). Incorrect installations may cause unnecessary EMI.
- If possible, install ballasts as far away from major communication sources.
- Do not coil your excess lamp cords or wiring. Shorten lamp cords and wires to the required lengths.
- Keep mains leads (power cords) and lamp leads separate.
- Maintain integrity of electrical system
- EMI may be more prevalent in areas with older grid systems.
Maintenance
SolisTek digital ballasts are not self‐serviceable. If you experience a need for assistance, please call our information line. Disassembling the ballast will void the warranty. The internal componentry of the ballast is sealed with a resin to protect electronics. The aluminum exterior of the ballast can be cleaned with a damp cloth, however, make sure the ballast is disconnected before cleaning.
It is recommended to check all connections regularly to make sure that no cables have become loose or show signs of damage. Also, check to confirm all wire ends are fitted firmly into the reflector/ballast.
