PowerLab for every DC electrical system

The calculation engine started with marine — because ABYC E-11 is the most demanding spec out there. That same engine now sizes RVs, tiny homes, food trucks, telecom sites, farm pumps, and a dozen other system types. Pick your use case:

rv

Design your RV electrical system: battery bank size, solar array, wire gauges, and inverter pick. Works for Class A, Class C, travel trailers, fifth wheels.

Typical daily load: 1,500–6,500 Wh

van

Plan the electrical for a Sprinter, Transit, or ProMaster build. Battery sizing, solar, 12V vs 24V, inverter pick, wiring schedule. Based on real vanlife loads.

Typical daily load: 1,200–3,500 Wh

tiny home

Size the electrical system for a tiny home on wheels or on foundation. Hybrid solar + grid, full-residential loads, inspection-ready permit reports.

Typical daily load: 4,000–12,000 Wh

off grid cabin

Design a reliable off-grid cabin power system. Solar + battery + generator sizing, full appliance catalog, inspection-ready reports.

Typical daily load: 3,000–8,000 Wh

sailboat

Design an ABYC E-11 compliant sailboat electrical system. Battery sizing, solar + alternator + shore power, wire runs, permit-ready diagrams.

Typical daily load: 1,000–4,000 Wh

food truck

Size your food truck electrical: generator vs. battery vs. shore power, commercial-fridge loads, espresso and griddle peaks, inspection-ready reports.

Typical daily load: 10,000–30,000 Wh

overlander

Size your overland rig electrical: aux battery, DC-DC, fridge, roof panels, winch, lights. ABYC-grade wire sizing for trail conditions.

Typical daily load: 600–2,500 Wh

backup home

Size a home battery backup system. Essentials vs. whole-home, hybrid solar, grid-down autonomy, code-referenced design reports.

Typical daily load: 3,000–10,000 Wh

telecom site

Size remote telecom / repeater site power: 48V battery plant, solar + generator hybrid, 24/7 uptime sizing, TL-9000 style availability targets.

Typical daily load: 8,000–18,000 Wh

farm pump

Size solar + battery for agricultural pumping: irrigation, livestock water, electric fence. Seasonal demand and backup generator planning.

Typical daily load: 2,000–15,000 Wh
