EcoFlow Delta 2
Jackery Explorer 300 v2
EcoFlow Delta Pro
LiFePO4 (lithium iron phosphate) batteries deliver 3,000–6,000 charge cycles vs. 500–1,200 for standard lithium-ion. No thermal runaway risk. In 2026, every serious solar generator uses LFP chemistry. If a model lists “lithium-ion” with fewer than 1,000 cycles, skip it — it’ll be at 60% capacity in 3 years.
How to Size a Solar Generator
The core question is watt-hours (Wh). That number tells you how long the unit can power a given load before needing a recharge.
The fridge benchmark: A standard 18–20 cu ft refrigerator draws ~150W continuously. Running it 24 hours requires 150 × 24 = 3,600Wh — the entire EcoFlow Delta Pro. Most Tier 2 units (~1,000Wh) run the same fridge for 5–6 hours.
Peak vs. continuous watts: Your continuous wattage is what the unit sustains indefinitely. Surge/peak is the brief burst needed for motor startup — a refrigerator needs 2–3× its running wattage at startup. A 1,800W continuous unit typically handles a 2,700W surge, which covers most refrigerators.
LiFePO4: 3,000–6,000 cycles, no thermal runaway risk, slightly heavier — the right choice for stationary emergency prep.
NMC (standard lithium-ion): 500–1,200 cycles, higher energy density (lighter), higher fire risk. Right for portability-first camping. Wrong for home backup that’ll sit in your garage for years.

EcoFlow Delta Pro Ultra is the only real choice for genuine whole-home backup. The EP500 Pro is better on paper (more cycles, lower price) but meaningfully less capable. At $3,999 vs. $2,200, the Delta Pro Ultra is worth the premium for anyone serious about this category.
Solar Panel Pairings
Match total panel wattage to ≤ your power station's max solar input. More watts = faster recharge. Rule of thumb: plan for 80% of rated panel wattage in real-world conditions (direct overhead sun is rare; clouds, angle, and temperature reduce output).
| Generator | Max Solar In | Recommended Panels | Est. Recharge Time |
|---|---|---|---|
| Jackery 300 v2 | 100W | 1× SolarSaga 100W Amazon (~$198) | ~4 hrs |
| EcoFlow River 2 | 110W | EcoFlow 110W Panel (~$150) | ~3.5 hrs |
| Jackery 1000 v2 | 400W | 2× SolarSaga 200W (~$249 ea.) | ~3 hrs |
| EcoFlow Delta 2 | 500W | 2× EcoFlow 220W Bifacial (~$220 ea.) | ~2.5 hrs |
| Bluetti AC180 | 500W | 2× Bluetti PV200 200W panels | ~3 hrs |
| Jackery 2000 Plus | 1,400W | 4–6× SolarSaga 200W | ~2.5 hrs |
| EcoFlow Delta Pro | 1,600W | 4× EcoFlow 400W panels | ~2.5 hrs |
| EcoFlow Delta Pro Ultra | 5,600W | 6–14× EcoFlow 400W panels | ~2 hrs |
Jackery uses a proprietary 8mm Anderson connector. Third-party panels require an adapter. EcoFlow and Bluetti use XT60 or DC5525 connectors. Stick to brand-matched panels unless you're comfortable sourcing adapters. Bifacial panels (SolarSaga 200W, EcoFlow 220W) add ~5–10% real-world output by capturing reflected light — worth the small premium.
What We Don't Recommend and Why
Gas Generators (for indoor/home use)
Gas generators have fundamental incompatibilities with emergency prep in residential settings:
- Carbon monoxide risk — must run outside only; CO kills silently indoors
- Fuel dependency — gas goes bad in 6–12 months; gas stations close during disasters
- Noise — 65–80dB is a security liability during civil unrest or grid events
- Maintenance — carburetors gum up if not run regularly; most people find them dead when needed
ReadyFive covers gas generators separately for outdoor/construction use cases where they're appropriate.
Unbranded Amazon Clones (<$200)
Any solar generator under $200 that isn't from Jackery, EcoFlow, Bluetti, or Anker. Problems: often use salvaged or off-spec cells with inaccurate capacity claims (a "500Wh" unit may deliver 250Wh), no thermal management, zero warranty support, and no solar panel ecosystem. The price difference funds actual engineering.
NMC Models Under 1,000 Cycles
This includes older Jackery Explorer models (pre-2022 v2 line) with NMC lithium-ion chemistry. At 500–800 cycles, you're looking at significant capacity degradation in 2–3 years of regular emergency use. All models in this guide use LiFePO4 — it's not close.
Frequently Asked Questions
Depends on the tier. A standard 18–20 cu ft fridge draws 100–200W running with a 400–800W surge at compressor startup. The EcoFlow Delta 2 (1,800W / 1,024Wh) runs a 150W fridge for ~5–6 hours. The EcoFlow Delta Pro (3,600W / 3,600Wh) runs it for 20+ hours. Any Tier 1 unit cannot reliably run a full-size fridge — they lack surge capacity and runtime.
Yes — one of the strongest emergency use cases. A CPAP without humidifier draws 30–45W. On the Jackery 300 v2 (288Wh) that's 6–9 hours — one night. On the EcoFlow Delta 2 (1,024Wh) that's 22+ hours. Multi-night CPAP users should go Tier 2 or higher.
Depends on the pump. A 1/2 HP shallow well pump draws 750–1,200W running with a 2,000–3,500W startup surge. You need at minimum the EcoFlow Delta Pro (3,600W peak surge) or Jackery 2000 Plus (6,000W surge). Tier 1 and Tier 2 units cannot reliably run a well pump.
Yes — this is the entire advantage over gas generators. No combustion, no carbon monoxide, no fumes. Safe in a bedroom, garage, or apartment. Cooling fans run 42–55dB at high load — audible but won't wake you. You can literally run one next to a sleeping CPAP user.
Yes — all units support 12V car charging via the cigarette lighter port. It's slow: a 1,024Wh battery at 120W (typical 12V car output) takes 10–12 hours. Use car charging as a supplementary option while driving, not a primary recharge strategy.
LiFePO4 at 3,000 cycles: running one full cycle per week means the battery lasts 57 years at 80% capacity. Realistic emergency prep use is 10–20 cycles/year — the battery will outlive your need for it. Cycle life is not a purchasing concern for this use case. Buy for output and capacity, not cycle count.
Solar wins for home and indoor use. Gas wins for construction sites and extended off-grid situations where solar recharge isn't possible. For 99% of ReadyFive readers — apartment dwellers, suburban homeowners, families with medical equipment — solar is the correct choice. The ability to run it indoors is decisive.
