Built by hand.
Backed by the builder.

IsoWatt is a one-person operation out of Lebanon, PA — assembling portable LiFePO4 power systems for people who work, camp, and live away from the grid.

The Story

Why IsoWatt exists.

Off-grid power has always been available — but never quite right. Mass-market brands ship plastic boxes with locked-down software, cheap cells, and no path to repair. Professional systems cost thousands and require a dealer to touch.

IsoWatt sits in the gap. Consumer-level price. Industrial-level build. Every unit uses LiFePO4 cells — the same chemistry in electric buses and grid storage systems — wired properly, fused correctly, and assembled in a way that can be serviced if it ever needs to be.

"If I wouldn't trust it to run my own gear all night, I won't sell it."

Each build is a direct reflection of the person behind it. There are no shortcuts taken, no cheaper components swapped in to improve margin. The BOM is the BOM, and the build is the build.

What We Stand For

No shortcuts.
No exceptions.

Correct Overcurrent Protection

Every circuit has the right fuse for the wire gauge. Every inverter has a dedicated breaker. ANL fusing on the main run. Not optional.

Derated Components

Switches, relays, and breakers are rated well above operating load. Lower heat, longer life, higher reliability under real-world conditions.

Proper Wire Gauge

6 AWG on main runs. 10–14 AWG on branch circuits. No undersized wire. No heat buildup. No fire risk from corner-cutting.

Transparent Pricing

No hidden fees. No bait-and-switch. You see the price before you reserve, and the price doesn't change when the bill comes.
