Three-Sine Portable Power builds construction-rated wheeled power stations purpose built to run induction motors pulling large loads using lithium-iron-phosphate battery power. Three-Sine stations fit through doorframes and are designed to withstand job site abuse.Three-Sine power stations can deliver up to 26 max kW of split, single-phase, or 19.5 max kW of 208 volt 3-phase AC power for up to 100 kWh.The stations easily add to their base capacity by pairing with portable 10, 30, or 60 kWh battery module units. Build a fleet of battery modules to give your team unlimited capacity for powering your job site.Three-Sine operates from and manufactures in Philadelphia, Pennsylvania. We are proud to help power the American construction market from America's birthplace. Call Three-Sine today and talk to us about custom receptacle suites and personalized unit branding.

three-sine products

The principal specifications for Three-Sine Portable Power stations are each 3S unit's max kilowatt (kW) output for any given moment, and the runtime capacity of the system.Battery capacity for Three-Sine systems is measured in terms of kilowatt-hours (kWh). The headline number indicates the number of hours the station can generate 1 kilowatt of output. The 15 kWh prototype will output 5 kW for 3 hours. The flagship 3S-26 runs the same load for 8 hours. A 3S-26 connected to a BM-60 will run that load for 20 hours.Battery modules are connected via Anderson 350 DC ports on the broadside of each unit. Each module is provided with an Anderson 350 connector cable. To add capacity, simply wheel a module alongside your main three-sine station, power down your station, and use the cord to connect each unit's Anderson port. The inverter system will automatically read the additional capacity upon restart, and you are ready to continue using your equipment.

3. 11-gauge slightly-rounded, angled iron framing.
4. Heavy-Duty treaded casters. Fixed-rear, swivel-front.

Three-Sine 3S power stations standardize on ergonomically sound 45" heights and 26" widths - ideal for fitting through any size entranceway. Fork pockets are built in to the iron base-frame and heavy-duty casters rated to at least 3x each unit's weight are flanged to the underside. Dimensional differences occur in the depth of each product's enclosure (shown below as its length in inches), and the unit's weight.Three-Sine stations are engineered to offer the full range of standard split-phase RMS voltage values from 110-250 with dedicated 240 volt, split, and 120 volt receptacles. The 3S-16 and 3S-26-208v stations output 3-phase power in a 208 volt structure. On all Three-Sine products the sine waves are produced with a total harmonic distortion between 2 and 3%.

In trying to figure out what is possible coming from a steel and iron box on wheels, that fits through doorframes; we had to get a little creative under the hood. The base 3S-26 model achieves its max 26 kW output via dueling 13 kW inversion systems. Each system's load is monitored on the unit's LCD.The 3S-26-208v is a single inversion system architecture. It is built for large split phase single loads, or dedicated 3-phase 208v applications. It absolutely pushes the limit for what is physically possible within the scope of the Three-Sine design philosophy.A contractor would purchase a 3S-26-208v for one or both of the following reasons:1. They have a split, single-phase load > 20 HP that is critical to their operations.
2. They have a 208v 3-phase load > 20 HP that is critical to their operations.The 3S-16 and 3S-26-208v's three-phase conversion process requires a 3-5 minute user operation involving system shutdown, unit access, pushing a button on the inversion system's internal LCD screen, and flipping a phase switch. The process is simple, straightforward, and clearly detailed in the operation manual. We will e-mail you video of the correct procedure being demonstrated, and if you call 215-309-9277, we will FaceTime with you and walk you through it step by step live on the phone. We are here to help!

Max Output Boosts

A Prototype, 3S-12, and 3S-16's rated max kW output is restricted by the DC power distribution architecture. This is a necessary safety feature built into the system to protect the ultimate asset of your life. The enormous battery bank of the 3S-26 allows for that base station to achieve max system output without modification. Adding battery module capacity safely allows for additional AC output from the inversion system and expands the system specifications.Connecting to a BM unit fundamentally changes the system's capabilities. In the tables below, the detail on how max kW output and kWh runtime are expanded through a connected system are shown. This brings to light the full capabilities of Three-Sine Portable Power products.

The philosophy is simple: give your crews reliable options. The Three-Sine product line delivers unprecedented battery power for it's size-class (19.5 kW, 3-phase capable) so you can run your largest job site tooling, kWh capacity that will run more conventional tool fleets for a full 8-hour day, and modular add-on capacity to give you the best of both worlds.

charging

Three-Sine stations are charged via inlets on the rear panel of each unit. The 240v inlet allows for extremely manageable refill times. The 120v inlet allows charging from any location and preserves the option of a cycle-capacity-maximizing trickle charge.

load profiles

Three-Sine power stations are virtually limitless in application within the unit's specifications. They are engineered for handling the most reactive inrush loads with low power factors and high kVa at startup. They can power wings of hospitals or planetary concrete floor grinders.

Contractor Businesses

Commercial contractors working with concrete are ideal Three-Sine customers often facing tough site conditions with intermittent or no grid power while working in enclosed spaces. Saws, grinders, and dust-suppression long ago moved to induction motors so this work can be reliably done without emissions or noise. Eliminate the diesel tow-behind in the parking lot and 300 feet of cord from your site plans by utilizing Three-Sine stations right at your work point. Emission and noise-free 3-phase power in arms length of the tool.In the below table, Three-Sine systems are paired with ideal load profiles using popular tool models from Husqvarna (Hq), EDCO (Ed), and Hilti (Hi). Three-Sine systems are either base 3S stations or paired with battery modules for additional capacity.

The modular system really eliminates the guesswork here. Build a fleet of add-on battery modules and swap them into base units in 30 seconds giving your site limitless capacity.

Emergency Services and Disaster Response

The portable and modular design of the product line allows disaster recovery teams to bring larger life-saving equipment to remote areas during search and rescue operations.Picture this: A disaster recovery team is utilizing the relatively calm 30-minute period afforded by the eye of a hurricane to lay out recovery systems and prepare for full-scale disaster response. They can start powering water heaters to create potable water at scale and provide emergency showers for thousands of disaster victims. Post storm, the crew can quickly deploy 3-phase power for search and rescue efforts from the bed of a pickup truck in a remote and destroyed enclosed area.Disaster recovery teams utilizing Three-Sine systems will save additional lives.
