Solar Panels for a Power Station: Sizing and Compatibility

A power station only helps until its battery is empty. Folding solar panels let you refill it during a long outage without fuel or a generator. The catch is that a panel and a station have to agree on voltage, current and connector, and the panel’s rating is a best case. Here’s how to size panels and check that they’ll work, with five 200 W class panels compared by their makers’ published specs. These are the makers’ figures as I read them on November 9, 2026, not my own measurements.

Battery and solar setups make no carbon monoxide. Canada.ca says battery- or solar-powered portable generators can be used anywhere. A fuel-burning generator is different: outdoors only, at least 20 feet (6 m) from doors, windows and vents.

The three numbers on a panel

• Rated watts (W). The output under standard test conditions. Jackery labels its specs “STC”. In real sun, with heat, clouds, angle and season, expect less.
• Open-circuit voltage (Voc). The panel’s highest voltage, with nothing connected. This must stay below your station’s maximum solar input voltage.
• Current (amps). Usually listed as short-circuit current (Isc) or operating current (Imp). Some stations cap the current they’ll accept.

The numbers on your station

Look for the solar or DC input line in the spec sheet. Here’s what four makers list:

Station	Solar input	Voltage range	Current limit	Connector (as stated)
EcoFlow DELTA 3 Plus	2 ports, 500 W each	11 to 60 V	Not listed	Not listed
Jackery Explorer 2000 v2	2 ports, 400 W max	11 to 60 V	12 A per port (16 to 60 V), 21 A combined	DC 8 mm
BLUETTI AC180	500 W max	12 to 60 V	10 A	MC4 panels (from FAQ)
Anker SOLIX C1000X	600 W max	11 to 60 V	10 A (11 to 32 V), 12.5 A (32 to 60 V)	XT-60

Anker’s page labels its spec table “C1000” while the product is the C1000X, so confirm with Anker if that matters to you.

Five folding panels, by published specs

Panel	Rated W	Voc	Operating V	Current	Weight	Water rating	Connector (as stated)
EcoFlow 220W Bifacial	220 front, 175 rear	21.5 V	18.4 V	Isc 12.4 A	about 15.4 lb (7.0 kg)	IP68	Photovoltaic connectors, XT60 cable included
Jackery SolarSaga 200W	200	22 V	18 V	Isc 12.5 A	14.33 lb (6.5 kg)	IP68	DC8020 to DC7909 adapter included
BLUETTI PV200S	200	26.5 V	Not listed	Isc 9.4 A	19.4 lb (8.8 kg)	IP65 junction box only	MC4
Anker SOLIX PS200	200	57.6 V	48 V	Imp 4.16 A	16.3 lb (7.4 kg)	IP67	MC4 cables, MC4 to XT-60 adapter
ALLPOWERS SP033	200	43.3 V	36 V	Isc 5.95 A	12.45 lb (5.65 kg)	IP67	MC4

A few notes from the makers’ pages: Anker’s US store page lists the PS200 at 20.34 lb (9.23 kg), while its SOLIX page lists 16.3 lb, so expect somewhere in that range. EcoFlow showed the 220W panel as sold out when I checked. BLUETTI says to avoid rain exposure and not to soak the PV200S. ALLPOWERS says its parameters may vary by version, and the page I could open was its UK store, so check the listing for your country.

Will it work with my station?

Run three checks for any panel and station:

1. Voltage. Panel Voc (or the sum, for panels in series) must be under the station’s maximum. Leave some headroom and follow the station manual.
2. Current. Compare the panel’s current with the station’s limit. If the panel is higher, you won’t get the extra watts, and the station manual says whether the setup is allowed at all.
3. Connector. MC4, XT-60, DC8020 and DC7909 are all different plugs. You may need the adapter the station maker sells or lists.

Worked examples using the tables above:

• Two EcoFlow 220W panels in series into one DELTA 3 Plus input: 21.5 + 21.5 = 43 V, under 60 V. Rated 440 W, under the 500 W port limit.
• Two BLUETTI PV200S in series into an AC180: 26.5 + 26.5 = 53 V, under 60 V. Isc 9.4 A, under 10 A. Rated 400 W, under 500 W.
• One Anker PS200 into a C1000X: 57.6 V, just under 60 V. Two in series (115.2 V) would be far over, and Anker’s FAQ says the panel suits stations with a maximum of up to 60 V.
• One ALLPOWERS SP033: 43.3 V works with any of these 60 V inputs. Two in series (86.6 V) would not.
• Jackery SolarSaga 200W into an Explorer 2000 v2: Jackery lists up to 400 W of DC input across two ports, so two panels, one per port, stay within that.

How much solar do you need?

Start from the station’s capacity and how fast you want to refill it.

Panel watts needed ≈ station Wh ÷ (hours of good sun × share of rating you expect).

As an example only, not a forecast: say you’ll get 5 hours of good sun and your panels average half their rating over that time. To refill a 1,024 Wh station:

1,024 ÷ (5 × 0.5) = about 410 W of rated panels.

That’s two 200 to 220 W panels. In winter, cloud or northern latitudes, real output can be well below that example, so a station may only partly refill in a day. Keep the panels pointed at the sun, adjust them through the day if you can, and keep them clear of shade, snow and dust.

Then check the result against the station’s maximum solar input. More panel watts than the input can take won’t charge faster.

Practical tips

• Weight and storage. These panels weigh from 12.45 lb (5.65 kg) to about 20 lb (9.2 kg) each. Store them flat and dry.
• Water ratings differ. IP68 and IP67 panels are rated for water; the PV200S rating covers only the junction box. Bring cables and adapters in when it rains, whatever the panel’s rating.
• Station stays inside. Run the cable through a door or window gap and keep the station dry indoors.
• Test before an outage. Set up the panels on a sunny day, check the station’s input reading, and note how many watts you actually get.
