Understanding Solar Compatibility with the DELTA (Gen 1)
MPPT Range & Why It Matters
The DELTA (Gen 1) accepts solar input between 10V and 65V (MPPT range). Panels with Vmp below 10V won't start charging — the MPPT controller can't lock on. Panels with Vmp above 65V may damage the input circuit.
Cold Weather Voltage Safety
We apply a 1.2x safety margin to each panel's open-circuit voltage (Voc) to account for cold temperatures, when solar cells produce higher voltage. The DELTA (Gen 1)'s maximum input voltage is 65V. Any panel whose Voc x 1.2 exceeds 65V is flagged as a voltage danger. 19 of 20 panels pass this safety check.
Cables & Adapters for the DELTA (Gen 1)
The DELTA (Gen 1) uses a XT60 solar input connector. XT60 is a standard connector shared across many brands. Most third-party panels with XT60 connect directly. 19 of 20 panels require an adapter with this unit.
Frequently Asked Questions
Can I use any solar panel with the EcoFlow DELTA (Gen 1)?
No. The DELTA (Gen 1) requires panels with Vmp between 10V and 65V, and cold-weather Voc (Voc x 1.2) under 65V. Of the 20 panels we tested, 16 are fully compatible, 3 work with limitations, and 1 are incompatible.
How long does it take to charge the DELTA (Gen 1) with solar?
With the fastest compatible panel (EcoFlow 400W Portable Solar Panel, 400W delivered), the DELTA (Gen 1) (1260Wh) charges in approximately 4.5 hours under real-world conditions (70% derate for angle, clouds, and temperature). The slowest compatible option (Jackery SolarSaga 80W Solar Panel) takes approximately 22.5 hours.
Do I need an adapter for solar charging the DELTA (Gen 1)?
The DELTA (Gen 1) uses a XT60 connector. 19 of 20 panels require an adapter. The remaining panels connect directly via XT60.
