Err 60
EcoFlow Portable Power Station
Severity: ModerateWhat it means
EcoFlow Err 60 means the DC charging side (solar input or 12V car charger input) has reported a fault — either the input voltage is out of spec, polarity is reversed, or the MPPT controller has detected an internal issue.
AC charging usually keeps working.
Err 60 almost always traces to the solar panel string or the cable feeding DC into the unit, not the EcoFlow itself.
Affected Models
- EcoFlow DELTA / DELTA 2 with XT60 solar input
- EcoFlow DELTA Pro with Anderson high-power input
- EcoFlow RIVER 2 / 2 Pro on solar or car-charger
Common Causes
- Solar panels wired in series exceeding the unit's max open-circuit voltage (60 V on RIVER 2, 150 V on DELTA Pro)
- Polarity reversed on a homemade XT60 or Anderson cable
- Cable break or chafe causing intermittent short on the DC input
- Car charger plugged into a socket that has reversed polarity (rare but possible on home-modified vehicles)
- MPPT controller internal fault
How to Fix It
-
Disconnect the DC input.
Pull the solar cable or car-charger cable out of the EcoFlow's DC input port.
Press the power button to clear the alarm.
If the error indicator goes away as soon as the input is unplugged, the fault is in what you were plugging in, not the EcoFlow. -
Check polarity on a homemade cable.
If you built or bought a third-party XT60 or Anderson connector, verify with a multimeter that the positive panel lead matches the EcoFlow's positive pin.
Reverse polarity on the DC input is the single most common Err 60 cause.
EcoFlow includes reverse-polarity protection but it still trips the error. -
Check solar string voltage.
Measure the open-circuit voltage across the cable with a multimeter, panels in full sun.
For DELTA 2: must be 11-60 V.
For DELTA Pro: must be 11-150 V.
If you wired panels in series for a long run and the open-circuit voltage exceeds the max, that's your Err 60 — rewire some panels in parallel. -
Try a different DC source.
If you have both a solar setup and a car charger, swap them.
If the car charger works clean but solar trips Err 60, the issue is in the panels or panel cable.
If both trip Err 60, the EcoFlow's DC input has a fault and needs service. -
Inspect the cable physically.
Run the solar cable through your hands looking for cuts, chafes, or melted insulation.
A pinched cable where the inner conductors are touching shorts the input and looks like a faulty source.
Replace any damaged cable before retesting.
