Pairing solar panels with a power station: Voc, input limits and cold-weather voltage
Checked: 2026-10-25. If you are wiring a permanent array, use a qualified installer.
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."
Input limits of pinned models
| Model | Solar input (manufacturer) |
|---|---|
| EcoFlow DELTA 3 Plus | 2 ports, 11–60 V, 500 W max each |
| Jackery Explorer 1000 v2 | 2 × DC8mm, 12–16 V at 8 A or 16–60 V at 10.5 A per port, 400 W max total |
| Anker SOLIX C1000 | 11–60 V; 10 A max at 11–32 V, 12.5 A max at 32–60 V; 600 W max |
| Anker SOLIX F3800 Plus | 2 × 11–165 V, 17 A max, 1600 W max each |
| EcoFlow DELTA Pro 3 | High-PV 30–150 V, 15 A, 1600 W; Low-PV 11–60 V, 20 A, 1000 W |
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):
- Worst-case Voc at 25°C: 22 × 1.05 = 23.1 V
- Coldest cell temperature you plan for, e.g. −10°C: difference = 25 − (−10) = 35°C
- Rise: 35 × 0.30% = 10.5% → 23.1 × 1.105 ≈ 25.5 V per panel
String counts by voltage only:
- 60 V inputs (DELTA 3 Plus, Explorer 1000 v2, SOLIX C1000): 2 in series = 51.0 V (OK); 3 in series = 76.5 V (too high).
- F3800 Plus (165 V): 165 ÷ 25.5 = 6.47 → max 6 in series (153 V).
- DELTA Pro 3 High-PV (150 V): 150 ÷ 25.5 = 5.88 → max 5 in series (127.5 V).
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.
Connectors and mixing
- EcoFlow and Anker C1000 use XT60-style solar inputs (Anker FAQ: "XT-60 connector"); Jackery uses DC8mm/DC8020. Cross-brand use needs an adapter; we have not found official cross-brand adapter compatibility statements, so check with both manufacturers.
- Jackery's page: "Mixing different models of solar panels is not recommended."
- EcoFlow 400W Portable Solar Panel (user manual): Voc 48 V, Vmp 41 V, Isc 11 A, Imp 9.8 A, voltage temperature coefficient −(0.33 ± 0.03)%/K. Same method at −10°C with the 0.36% upper bound: 48 × (1 + 35 × 0.36%) ≈ 54.0 V per panel, so one panel fits a 60 V input and two in series (≈108 V) need a High-PV input such as DELTA Pro 3 (150 V) or F3800 Plus (165 V). The manual does not recommend parallel connection because the station's input current limit restricts the total.
