Why sizing first beats buying fast

  • Right sized the first time - Overbuying wastes money and weight; underbuying leaves you in the dark. Sizing balances capacity, output, and charge speed with real world use.
  • Reality over spec sheets - We decode continuous vs. surge watts, usable battery capacity (after inverter and round trip losses), charging bottlenecks, and how "peak" numbers differ from everyday performance.
  • Designed for your lowest sun month - We plan for the lowest monthly Peak Sun Hours (PSH) at your location, not the average. That keeps your system reliable during cloudy or rainy seasons - not just on perfect days.
  • Weekly market & pricing scans - We track current stock, bundles, and price shifts to help you buy at the right time, with the right accessories.
  • Apples to apples comparisons - Different brands list features differently. We normalize specs so you can confidently compare Jackery vs. EcoFlow vs. others on value and performance.
  • Transparent about limitations - Portable stations are amazing - but not magic. We highlight where a portable solution shines and where a fixed or hybrid setup makes more sense.

What's Included in Our Sizing Service

A Quick Sizing Guide

Our Method, in Plain Numbers

Use-Case Example: Remote Work Setup
  • Wi-Fi Router (10W x 24h) 240 Wh
  • Laptop (60W x 6h) 360 Wh
  • 2x LED Lights (10W x 5h) 100 Wh
  • Smartphone (15W x 2h) 30 Wh
Required Daily Energy (15-25% Buffer for inverter and conversion losses)

~840-915 Wh/day

Recommendation

If you want 1.5 days without charging: 915Wh x 1.5 = 1,370Wh usable. Accounting for battery chemistry and DOD (i.e. keeping 10-20% reserve), your target is a class station with a 1,600-1,800W capacity.

Solar Replenishment

  • Design for lowest sun month: Required panel watts ≈ (Daily Wh) ÷ (lowest month PSH × system efficiency).
  • If lowest month PSH at your site is modest, you'll need more panel watts or more charging time (or occasional AC top ups).

Inverter Right Sizing

  • Continuous watts must exceed your simultaneous running loads.
  • Surge must cover startup spikes (compressors, motors).
  • We check duty cycles so you don't overbuy for brief peaks.
Pros vs. Cons

Great fits

  • Apartments and rentals (no roof rights).
  • Travel, camping, off grid field work, events.
  • Short grid outages, routers/TVs/laptops, CPAP (with proper assessment).
  • DC first setups (USB C laptops/phones, 12V fridges).

Tough fits

  • High draw resistive heating (kettles, irons, electric stoves) and large A/C units.
  • All day heavy refrigeration or pumps without sufficient PV area.
  • Whole home backup beyond brief essentials.

Jackery vs. EcoFlow vs. Others

How we compare fairly

  • Battery chemistry & cycle life: LiFePO4 often offers longer cycle life; NMC is lighter for the same capacity. We match chemistry to your priorities.
  • Charging speed: Some models support very fast AC + PV charging; we verify realistic input limits so panel kits aren't bottlenecked.
  • Ecosystem & expandability: Extra batteries, smart panels, or app features vary.
  • Noise & thermal behavior: Fan curves and thermal throttling affect quiet spaces and hot climates.
  • Service & warranty: We factor region specific support and turnaround times.

Intake Checklist

What we'll need from you

  • Location (town/coordinates) and typical use months.
  • List of devices, rated watts, and hours of use. Photos of labels help.
  • Which devices run at the same time.
  • Must have vs. nice to have loads.
  • Preference for weight/portability vs. runtime.
  • Panel portability constraints (folding vs. rigid, max size/weight).
  • Backup charging options available (wall, vehicle, generator).
  • Budget range and purchase timeline.
Use Cases

Example Scenarios

Remote work kit (day travel):

Loads: 1 laptop, phone, router, light.

Result: 500-800Wh station + 100-200W folding panel for daily top ups.

Apartment essentials during outages:

Loads: router, lights, TV, laptop, small fridge (duty cycled).

Result: 1,200-2,000Wh station, 300-600W PV (lowest sun design), clear rules on kettle/iron usage (usually avoid).

Field refrigeration (12V fridge):

Loads: 40-60W avg, higher on compressor start.

Result: 1,000-1,500Wh station + 200-400W PV; shade management and ventilation plan.

Frequently Asked Questions

Often impractical; very high watts and energy. We'll calculate it for your exact model and advise alternatives.

Sometimes. We verify maximum sustained input limits and what happens thermally over a full cycle.

If longevity and frequent cycles matter, probably yes. If every kilogram counts, NMC may fit better. We quantify the trade off.

Only if sized for your lowest PSH month and used with good tilt, minimal shading, and energy discipline. We design for that.
