EcoFlow Compatibility & Interoperability Matrix

This document defines what connects to what within the EcoFlow ecosystem.

🔋 Extra Battery (EB) Compatibility

Can I plug a battery from Model X into Model Y?

Main Unit	Compatible Extra Batteries	Notes
Delta 2	Delta 2 EB	Can technically use Delta Max EB (Capacity display might be buggy).
Delta 2 Max	Delta 2 Max EB, Delta 2 EB, Delta Max EB	Highly versatile. Treats Delta 2 EB as a generic expansion.
Delta Max	Delta Max EB, Delta 2 Max EB (Limited support)	Delta Max 1600 is incompatible with Delta 2 EB due to discharge rate (1C) risks.
Delta Pro	Delta Pro EB	Proprietary Voltage. Cannot use generic Delta batteries.
Delta Pro 3	Delta Pro 3 EB, Delta Pro EB (with adapter)	Backwards compatible with original Pro batteries.
Delta 3 Plus / Max	Delta 3 Plus/Max EB, Delta 2/Max EB, Pro 3 EB¹	¹ Requires multi-step adapter chain (see below).
River 2 Series	NONE	River 2 series units are not expandable (sealed).
River Pro (Old)	River Pro EB	専用 cable required.

Hack Note: See hardware/EXTRA_BATTERY.md for how to bypass these limits using the “Resistor Hack” to connect generic 48V batteries to Delta 2 / Delta Max ports.

The “Bridge” Solution: To connect a Delta Pro 3 Extra Battery to a Delta 3 Plus/Max (or Delta 2/Max), you need: Pro 3 EB -> EB Cable -> Smart Generator Adapter -> XT150 Cable -> Main Unit.

Power Kit Batteries (2kWh / 5kWh): These are NOT directly compatible with Delta/River units via a simple cable. They require the Power Hub OR the LFP Battery Polarity Adapter (making them a generic 48V source, which then requires the Resistor Hack to feed a Delta unit).

☀️ Solar Panel Compatibility

Can I use Solar Panel X with Power Station Y?

Rule of Thumb:

1. Voltage (Voc): Must be BELOW the Power Station’s limit. (Exceeding Voc = Instant Damage).
2. Amperage (Imp): Can be higher (Station will just clip it).
3. Connector: Most Panels are MC4. EcoFlow is XT60/XT60i. Use an adapter.

Input Limits Table

Unit	Max Voltage (Voc)	Max Input (W)	Connector
River 2	30V	110W	XT60
River 2 Max	50V	220W	XT60
River 2 Pro	50V	220W	XT60
Delta Mini	75V	300W	XT60
Delta (OG)	65V	400W	XT60
Delta 2	60V	500W	XT60i
Delta Max	100V	800W (Dual Port)	XT60i
Delta 2 Max	60V (x2 Ports)	1000W (500W x2)	XT60i
Delta Pro	150V	1600W	XT60i (High Voltage)

🔌 Charging & Grid-Tie Accessories

Main Unit	PowerStream (Microinverter)	Alternator Charger (800W)	Notes
Delta Pro 3	✅	✅	Alt Charger needs adapter.
Delta 3 Plus / Max	✅	✅	Direct XT150 connection.
Delta Pro	✅	✅ (Needs Adapter)	PowerStream needs BKW-DeltaPro cable. STREAM Micro connects via standard MC4/Grid.
Delta 2 Max	✅	✅ (Direct XT150)	Best match for Alternator Charger (Fast charge).
Delta 2	✅	✅ (Direct XT150)
Delta Max	✅	✅ (Direct XT150)
River 2 Series	✅	✅ (Via XT60 adapter)	Alt Charger output (800W) might exceed River input limits! Check specs.
STREAM Ultra	✅ (Integrated)	✅ (Internal)	All-in-one unit. Can connect to additional DELTA batteries.

⚙️ Smart Generator Compatibility

• Smart Generator (Dual Fuel):
  • Direct Connect: Works efficiently with Delta Pro & Delta Max / 2 Max via the Extra Battery Port.
  • Auto-Start: Only works if connected via the dedicated cable which passes data.
  • Generic Use: Can charge ANY station via the AC outlet on the generator (inefficient conversion).
