Built to be open
Power, without
the mystery.
A modular inverter system engineered for tinkerers, hackers, and anyone who believes their gear should make sense. 256 Wh. Fully serviceable. No black box.
The system
Every component does its job.
Design philosophy
Function dictates form.
Every vent, port, and fastener on a VoltPak exists because it has to. No decorative grilles. No gloss finishes. No mystery about what's inside.
Matte ABS chassis. Visible airflow paths. Standard hardware. The kind of product you can open, understand, and make your own.
Why VoltPak
Engineered for people who ask how it works.
Touchscreen shows real-time wattage, battery state, port status, and temperatures. No hidden states. No guesswork.
Buy the inverter core standalone. Bring your own battery. Expand when you need to. Upgrade without replacing everything.
Standard screws throughout. Replaceable panels. Battery compartment isolated. Designed to be opened, not voided.
Use cases
Wherever the work happens.
Power your bench. Mod it if you want. We designed for that.
Silent. Compact. Runs all night off a 220W panel.
Circular saw, lights, drill - all day, no generator.
Fridge, router, CPAP. Ready before the outage starts.
The lineup
Pick your build.
1,024 Wh. Fully serviceable. No black box.
2,048 Wh. More capacity, same open architecture.
Add capacity without swapping the core. Same isolated LFP compartment.

“Finally a power station I can actually open. Swapped the fan for a quieter one in 20 minutes. Everything is exactly where you'd expect it.”
“Ran our fridge, router and CPAPs through a 14-hour outage without a hiccup. The display showing real wattage draw is genuinely useful.”
“Bought the inverter core first with my own LiFePO4 pack. Worked first try. Added the VoltPak battery six months later. Exactly as advertised.”
