What will it run,
and for how long?

Build a load list, set your latitude and season, add NUESolar recharge — and get the case that carries the mission.

This planner is a best-guess estimate built from published specifications and typical duty cycles — not a guarantee of performance. Confirm mission-critical loads with a New Use Energy professional before you deploy.

10% reserve held back. Every runtime below uses 90% of rated capacity, not 100%. Cycling a LiFePO4 pack to empty shortens its service life — the bottom 10% stays in the bank so you keep the full 6,000-cycle rating.

Energy accounting

runtime = (rated Wh × 0.90) ÷ (load W ÷ path efficiency − recharge W)

  • 90% usable capacity. A 10% reserve is held back to protect cycle life. The 605 gives 483Wh of its 537Wh, the 1213 gives 1,152 of 1,280, the 2425 gives 2,304 of 2,560, the 3651 gives 4,608 of 5,120.
  • Inverter conversion: 90%. AC loads are drawn through the pure sine wave inverter, so 100W at the outlet pulls ~111W from the pack.
  • DC conversion: 96%. Devices marked DC run off the 12V, 48V, or USB-C ports and skip the inverter entirely — noticeably more runtime for the same device.
  • Charge conversion: 98%. A 2% loss is applied to everything coming in from solar or a fuel cell before it reaches the cells.
  • Duty cycle. Cycling loads — refrigeration, HVAC, power tools — don't draw full power continuously. Runtime uses average draw; Peak AC assumes everything is on at once and must clear the inverter's continuous rating.
  • Start surge headroom is estimated at 2× continuous rating. Confirm inrush from the spec sheet for critical motor loads.

Solar & fuel cell

  • Latitude and season drive harvest. Peak sun hours are applied per band, then derated 15% for field conditions — soiling, cable loss, panel temperature, and the imperfect tilt you actually get in the field.
  • Array voltage must match the controller. The 605 and 1213 accept 13–100V; the 2425 and 3651 need 70–150V. The SunFold modules run at 72V and feed all four cases. The Tactical 200W (24V) and Tactical 120W Rollup (35V) sit below the 70V floor and will not drive a 2425 or 3651 — the calculator flags this rather than quietly ignoring it.
  • Controller ceilings. 605 — 400W · 1213 — 600W · 2425 and 3651 — 1,700W. Array wattage above the ceiling is clipped, and the calculator says so.
  • The SFC EMILY 3000 runs day and night, which is the point of it — 125W of steady output regardless of latitude, season, or weather, and 3,000Wh over a full day. Offered on the 605 and 1213 only, matching its 12/24V output to those cases' 24V architecture.
  • Film fixtures are listed at full output. Dimming an LED fixture cuts draw close to proportionally — a SkyPanel S60-C at 50% is roughly half the load and double the runtime.
  • Planning estimates only. Actual results vary with temperature, weather, load profile, cable runs, and battery age.
