Power Packs

Power packs & applications

SETI Power Packs store energy electrostatically in a graphene matrix rather than through the chemical reactions a battery depends on. Nothing degrades, so the pack that ships today is still the pack you have in thirty years.

Weight, dimensions and charge time for the 200Ah pack are being confirmed against production units and are published here as soon as they are final. We would rather leave a field blank than print a number we cannot stand behind.

A note on the 48V name. These packs run at 52.2V nominal, which is exactly what a 48V system wants — the same way a “12V” lead-acid battery actually sits at 12.6V. We label them 48V because that is the system they are built to run, and calling them 52V has only ever caused people to wonder whether they fit.

Why a supercapacitor, not a battery

The difference is where the energy is kept.

A lithium battery stores energy by driving a chemical reaction, and that reaction is what wears it out. Every cycle moves material that does not move back perfectly, which is why capacity fades and why a battery has a cycle count at all.

SETI Power Packs use graphene-infused EDLC supercapacitor cells. Charge is held electrostatically on the surface of the graphene — no material migration, nothing consumed. There is no lithium, cobalt or phosphate anywhere in the pack, and no mechanism for thermal runaway.

Cycle life
30,000+ cycles at over 80% capacity retention.
Design life
30 years, backed by a 10-year warranty.
Charge time
Minutes, not hours — charge is accepted as fast as the source delivers it.
Operating range
−20°F to 150°F at full output, with no derating at either end.
Maintenance
None. No watering, no equalisation, no service interval.
Safety
No thermal runaway pathway — absent, not mitigated.

SETI Industrial

Grid stabilisation, industrial backup, telecom and data centre UPS.

“A cell site sits on a hill an hour from the depot. Its batteries are replaced every four years whether they have been used or not, because nobody will gamble a tower on a pack that might have quietly died in the heat.”

The job SETI Industrial is built for
0Scheduled maintenance visits over the life of the pack
30 yrDesign life, against a four-year replacement cycle
150°FFull output in an uncooled cabinet in August
InstantFull current on demand, no spin-up
Telecom
Backup for towers, switching stations and remote network equipment, where every service visit is a truck roll.
Data centre UPS
Instant transfer for mission-critical loads, with far less cooling load than a lithium battery room.
Process backup
Ride-through and clean shutdown for manufacturing lines, so a dip on the grid does not scrap a batch.
Grid services
Peak demand management, frequency regulation and renewable integration at utility scale.

SETI Solar

Storage that lasts as long as the array it is attached to.

A solar array is warranted for twenty-five years. Lithium storage attached to it is typically finished in five to eight. That means buying the storage three or four times over the life of the array — and sizing it twice, once for what it does today and once for what it will have faded to by year six.

Size it once

No degradation curve to design around. The capacity you specify on day one is the capacity you still have when the array is halfway through its warranty.

Capture the whole peak

Charge is accepted as fast as the array can deliver it, so a burst of midday generation goes into storage instead of being clipped.

Grid-tie or off-grid, same hardware

98% round-trip efficiency, compatible with standard inverters, and no separate product line for off-grid installations.

Leave it alone

Rooftop, carport or field, in Florida heat or a northern winter — no watering, no equalisation, no annual service call.

SETI Sports

A cart on a charger is a cart earning nothing.

Golf fleets

Charge between rounds, not overnight.

A lead-acid fleet is a schedule: eight hours on charge, a watering round every few weeks, and a full replacement every three or four seasons that lands in the capital budget whether the season was good or not. A pack that refills in the time it takes to turn a group around changes how many rounds the fleet can sell in a day, and takes the replacement line out of the budget entirely.

  • 5–20 minute recharge
  • No watering or equalising
  • Lighter than the lead-acid it replaces
  • No fleet-wide replacement cycle
Recreation vehicles
ATVs, UTVs and utility vehicles, where power-to-weight decides how the thing actually drives.
Venue backup
Instant transfer for scoreboards, timing systems and critical venue equipment.
Event power
Portable power for tournaments and outdoor events, set up in minutes and stored between seasons without losing charge.

SETI Outdoors

Where there is no service call and no second chance.

NoneThermal runaway pathway in an enclosed cabin

“Off-grid is where storage gets judged honestly. Nobody is coming out to look at it on a Sunday. Either it works, or the trip is over.”

The job SETI Outdoors is built for
RV & motorhome
Extended boondocking with fast solar recharge, and less weight than the battery bank it replaces.
Marine
House banks that tolerate vibration and salt air, and hold charge through a season on the hard.
Off-grid cabins
Solar storage for cabins, tiny homes and remote sites with no maintenance visit built into the plan.
Emergency
Backup that can sit untouched for years and still deliver full output the day it is needed.

Services and support

What comes with the hardware.

We are a small company on purpose. The people who answer the phone are the people who design and build the packs, which means you are not explaining your installation to a call centre and waiting for it to be escalated to someone who understands it. That shapes everything below.

Application sizing
Tell us the load, the duty cycle and the environment. We will specify the pack rather than leave you to work it out from a datasheet — how many, what voltage, what capacity, and what it will actually do on the worst day of the year.
Integration support
Grid-tie and off-grid on the same hardware. Compatible with standard inverters and charge controllers, and we will work through the wiring, the BMS interface and the commissioning with your installer.
Technical support
Direct access to the engineers. Phone and email, 8am–6pm ET, Monday to Friday. No ticket queue between you and the people who know the hardware.
Warranty
10 years, on a pack designed for thirty. Register the product after installation and the coverage and serial numbers stay on file, so a claim does not start with you hunting for paperwork.
VAR programme
Reseller and integrator partnerships for installers, system builders and fleet operators — pricing, technical training and support for the people specifying us into their own projects.
Fleet monitoring
Optional Seti AI monitoring for packs in the field, from a single site to a whole fleet — live telemetry, alerting and history, with a free tier that runs on your own hardware.
