Series adds voltage; parallel adds current. Your power station's solar input limits decide which works: cold-weather Voc in series must stay under the maximum input voltage, and current in parallel should stay within the input's amp rating.

Input limits

StationSolar input (manufacturer)
EcoFlow DELTA 3 Plus2 ports, 11–60 V, 500 W max each
Jackery Explorer 1000 v22 × DC8mm, 16–60 V at 10.5 A per port, 400 W max total
Anker SOLIX C100011–60 V; 12.5 A max at 32–60 V; 600 W max

Worked example: two Jackery SolarSaga 200W panels

Jackery lists Voc 22 V ±5% and Isc 12.5 A ±5%. Our Voc guide works out a cold-weather Voc of about 25.5 V per panel at −10°C.

So for these panels and stations, series is the fit. Three in series (about 76.5 V) is too high for a 60 V input.

Larger panels

EcoFlow's 400W panel has a Voc of 48 V. One panel fits a 60 V input; two in series need a high-voltage input such as the DELTA Pro 3's 30–150 V port. EcoFlow's manual does not recommend parallel connection for this panel because the station's input current limit restricts the total.

Disconnect panels before changing wiring, and never exceed the station's maximum input voltage: overvoltage can damage the input. In cold weather Voc rises; see cold-weather storage, and size the rest of the system with the sizing guide. Full station specs are in the 1 kWh comparison.
