EcoFlow Solar Panel Compatibility Guide (2026) — All Models
EcoFlow makes several power station models with different solar input specifications. This compatibility guide covers every EcoFlow model's voltage range, connector type, and solar input limits so you can choose a compatible panel.
Quick Answer
EcoFlow solar input specs by model: RIVER 2 (11-30V, 220W, XT60), RIVER 2 Pro/Max (11-50V, 220W, XT60), RIVER Pro (10-25V, 200W x2, MC4-to-XT60), DELTA 2 (11-60V, 500W, XT60), DELTA 2 Max (11-60V, 1000W, XT60), DELTA Pro (11-150V, 400W x2, XT60). Always match your panel's voltage to your model's range.

RIVER series compatibility
The EcoFlow RIVER series has the most restrictive solar input limits. RIVER 2: 11-30V, 220W max, XT60 connector. RIVER 2 Pro and RIVER 2 Max: 11-50V, 220W max, XT60. RIVER Pro: 10-25V, 200W per port (two ports), MC4-to-XT60 adapter. The RIVER Pro's 25V limit is the most restrictive — most 100W panels (Voc ~22V) work, but many 200W panels (Voc 24-27V) exceed the limit. For RIVER models, stick to 100-160W panels and verify Voc carefully.
DELTA series compatibility
The DELTA series accepts higher voltage and wattage, making it more flexible. DELTA 2: 11-60V, 500W max, XT60. DELTA 2 Max: 11-60V, 1000W max, XT60. DELTA Pro: 11-150V, 400W per port (two ports), XT60. The 60V limit on DELTA 2 allows most single panels and series-wired pairs. The DELTA Pro's 150V limit is compatible with residential panel arrays, making it the most versatile EcoFlow for semi-permanent solar installations.
Connector types
All current EcoFlow models use XT60 for solar input. Most solar panels use MC4 connectors, requiring an MC4-to-XT60 adapter (included with EcoFlow-branded panels). Some older EcoFlow models used MC4 directly. If your panel uses Anderson Powerpole or a DC barrel connector, you need a matching adapter. Always use quality adapters — poor connections waste power as heat and can melt under high current.
Third-party panel compatibility
EcoFlow stations work with most third-party monocrystalline panels as long as the voltage is within range and you have the correct connector adapter. Popular compatible third-party panels include Renogy 100W (Voc ~22V, works with RIVER and DELTA), BougeRV 100-200W (verify Voc for your model), and HQST 100W (Voc ~22V). You don't need to buy EcoFlow-branded panels — many users save money with third-party panels plus an MC4-to-XT60 adapter.
Frequently Asked Questions
Do I need EcoFlow-branded solar panels?
No. EcoFlow panels are convenient because they include the correct connectors, but any panel with a compatible voltage range and MC4 output works with an MC4-to-XT60 adapter. Many users save money with third-party panels from Renogy, BougeRV, or HQST. Always verify the panel's Voc is within your EcoFlow model's input range.
What happens if I exceed the EcoFlow's voltage limit?
Connecting a panel with a Voc above your EcoFlow's maximum can permanently damage the station's solar input circuitry. Always check the panel's Voc against your model's voltage range before connecting. This is the most important compatibility check — exceeding voltage is more dangerous than exceeding wattage.
Can I connect residential solar panels to an EcoFlow?
The DELTA Pro (150V limit) is compatible with some residential panel arrays, making it suitable for semi-permanent off-grid installations. The RIVER and DELTA 2 (25-60V limits) are less compatible with high-voltage residential panels. Always verify the array's combined voltage is within your EcoFlow model's range.
