Power station and solar panel guides
The numbers on a spec sheet, what each one limits, and how to check them yourself.
- How a power station's solar input voltage window works
Anker's C300 accepts 11 to 28 V from a solar panel, the C1000 Gen 2 takes 11 to 60 V. Learn what the volt, amp and watt limits on a solar port mean.
- Why cold mornings raise panel voltage
A 48.5 V panel reads about 57 V at -17 °C with a 1.18 factor. See why cold raises solar voltage and how to check a 60 V station limit.
- Series vs parallel panels for a power station
Two EcoFlow 400 W rigid panels give 74.2 V in series or 27.58 A in parallel. A DELTA 3 allows 60 V and 15 A. See how the sums work.
- XT60 vs XT60i: what changed and which cable to buy
XT60i adds a 1 A signal pin to the XT60 plug. EcoFlow sells a 2.5 m XT60i and a 3.5 m XT60 solar cable, each tied to different stations.
- DC7909 vs DC8020: the barrel plugs on Jackery and Bluetti
DC7909 has a 0.9 mm center pin and DC8020 a 2.0 mm pin, and Jackery says they are not interchangeable. See which stations use each plug.
- MC4 connectors explained
MC4 plugs are typically rated 20 to 30 A, and IEC 62852 covers PV connectors to 1,500 V and 125 A per contact. See how gender and ratings work.
- How to read a panel datasheet
EcoFlow's 400 W rigid panel prints 37.1 V Voc with a 3 percent tolerance. Learn what Pmax, Voc, Vmp, Isc, Imp and the temperature coefficient mean.
- Usable watt-hours: why you get less than the rated Wh
Jackery runs its Explorer 1000 v2 math at capacity times 0.85, so 1,070 Wh plans out to about 910 Wh. See what else trims a station's runtime.
- Surge vs continuous watts and motor start loads
Honda lists a 1/2 HP sump pump at 1,050 running W and 2,150 starting W, while stations print 2x surge ratings. See how to compare the two.
- LiFePO4 vs NMC in power stations: cycle life and weight
Of 81 stations from four makers, 71 name LiFePO4 and none name NMC. Cycle ratings run 2,500 to 6,000, but the percent threshold changes the meaning.
- Expansion battery rules by brand: generation locks and counts
Jackery's Explorer 1000 Plus takes 3 packs for 5,058.56 Wh, but its battery is not compatible with the HomePower 1000 Plus v2. Rules for four brands.
- UPS and EPS switchover times: what under 20 ms means
EcoFlow's RIVER 2 lists 30 ms, its DELTA 3 lists 10 ms, and a Jackery 5000 Plus offers 0 ms in online mode. See what each label and number means.
- Car charging limits: fuses, amps and hours
A 12 V car outlet at 8 A gives 96 W, so a 1,024 Wh EcoFlow DELTA 3 needs about 10.7 hours. See the fuse and amp limits that set the pace.
- UL 2743 vs UL 9540: what a listing covers and does not
UL 2743 stops at 20 kWh of lithium-ion capacity, and UL 9540 covers packs above that. See what each listing names and what it leaves out.
- Model names decoded: v2, Plus, Gen 2, Max and Ultra
Anker's F3800 Plus widens the solar window from 60 V to 165 V, while a Jackery v2 drops expansion. See what each suffix changed across four brands.
- Third-party panels and warranty: what each maker's terms say
EcoFlow's warranty excludes use with third-party accessories, while Bluetti's manual names 12 to 60 V MC4 panels. Compare four makers' wording.
- Portable power station or gas inverter generator
Honda's EU2200i runs 3.2 hours per 0.95 gal tank at 1,800 W, while a 1,024 Wh power station covers 1,800 W for about 34 minutes. Compare fuel and noise.
