Users can buy universal solar panels with MC4 connections to power EF DELTA, as long as the voltage and
current (10-65V DC, 10A max) comply with the specifications of EF DELTA, the panels will be able to
recharge EF DELTA through the MC4 to XT60 conversion cable. However, EcoFlow will not be responsible
for providing free repair services for any damage to the product caused by the quality issue or improper
operation of the third party solar panels, even during the warranty period. It is essential that users check the
positive and negative connections are correct. Reverse polarity connections are a common mistake, will
damage the Delta and will not be covered by the warranty.
3. EF DELTA supports the use of third party solar panels (DIY solution)
When EF DELTA is used under UPS or multi-machine series mode, EF DELTA's X-STREAM system supports
an entry-level UPS (Uninterruptible Power Supply) function, and you can use the EF DELTA AC socket
while the device is connected to a wall socket with AC power supply (The AC power comes from the grid,
not the battery). When the grid loses power suddenly, the device can automatically switch to EF DELTA
battery power mode in <50ms to ensure your work is uninterrupted provided the needs of your computer
do not require a faster cutover speed. It the responsibility of the user to determine whether this cut over
time is sufficient to ensure uninterrupted performance of their system.
