Pairing solar panels with a power station: Voc, input limits and cold-weather voltage

Pinned models: Jackery SolarSaga 200W, EcoFlow DELTA 3 Plus, Jackery Explorer 1000 v2, Anker SOLIX C1000, Anker SOLIX F3800 Plus, EcoFlow DELTA Pro 3 · Last checked 2026-10-25

The rule: the panel string's open-circuit voltage (Voc) in the coldest weather must stay below the power station's maximum solar input voltage. Power above the input limit is simply not used; voltage above it can damage the input. Anker's F3800 Plus FAQ warns that "exceeding 165V may cause damage to the solar input ports."

Example panel: Jackery SolarSaga 200W (bifacial)

From Jackery's spec table: Voc 22 V ±5%, Isc 12.5 A ±5%, Vmp 18 V, Pmax 200 W ±5%, voltage temperature coefficient −(0.27 ± 0.03)%/°C, max system voltage 60 V.

Worked maths: cold-weather Voc

Voc rises as temperature falls. Jackery labels its figure a "voltage temperature coefficient" without saying it is specifically the Voc coefficient; applying it to Voc is our planning assumption. Using the listed coefficient (we use the upper bound, 0.30%/°C, to be conservative, and the +5% tolerance):

  1. Worst-case Voc at 25°C: 22 × 1.05 = 23.1 V
  2. Coldest cell temperature you plan for, e.g. −10°C: difference = 25 − (−10) = 35°C
  3. Rise: 35 × 0.30% = 10.5% → 23.1 × 1.105 ≈ 25.5 V per panel

String counts by voltage only:

Current

Series strings keep the same current. The panel's Isc (up to 13.1 A with tolerance) is above the Jackery 1000 v2 port's 10.5 A and the C1000's 12.5 A limit. Jackery's FAQ describes the 1000 v2's 10.5 A per port as a "Current Limit", but neither Jackery nor Anker states on the pages or manuals we checked whether connecting a panel with a higher Isc is allowed, so this guide makes no recommendation either way. Jackery's own page sells this panel bundled with the 1000 v2.
