DELTA 1300Wh

◆Can I connect EF DELTA together?

Theoretically speaking, you can connect as many EF DELTAs in serial (but not in parallel) as you want. However, the efficiency of the machines will be seriously compromised (The energy consumption of the inverters grows with the number of the connected machines). As a result, we do not recommend to connect more than 3 EFDELTAs in serial, and it is necessary to fully charge every EFDELTA before you connect them together. Moreover, connecting EFDELTA in serial will not increase the rated output, but will expand the capacity.


◆Can I use EFDELTA to charge my devices while it is charged through the car port?

EFDELTA can be recharged through your car port and power your devices simultaneously.


◆Can I charge my EFDELTA through the DC and AC port at the same time? If so, does EFDELTA prioritize taking in electricity through the DC (solar) port?

When EFDELTA is charged through the AC and DC port at the same time, it will prioritize taking in power through the AC port. After you plucked out the AC cable, EFDELTA will start taking in electricity through the DC port.


◆What is the charging time when EFDELTA is charged by an AC cable?

EFDELTA can be recharged to 0%~80% in 1 hour, and be fully recharged in 1 hour 40 minutes.


◆What is the charging time when EFDELTA is charged by a car port cable?

EFDELTA can be fully charged through a 13.6V car port in 10-12 hours.

Most models from Tesla (Model X, the new version of Model S, Model 3) can be charged by EFDELTA, but the old version of Model S cannot be charged by EFDELTA.

Please note that in order to meet the UL2743 standard, DELTA's sockets are not grounded. However, we conducted hundreds of tests on different devices, and the finding is that only Tesla needs a grounded cable, other electric vehicles and equipment with grounded chargers can all be charged by EFDELTA properly.


◆What is the recommended temperature range for use of EFDELTA?

Discharge Temperature Range: -4-113°F (-20-45°C)

Recharge Temperature Range: 32-113°F (0-45°C)                                                    

When the ambient temperature is above 113F or below -4F, the high temperature or low temperature warning icon on EFDELTA's screen will light up and flash correspondingly. At the same time the battery management system will regulate the input and output of power to protect EFDELTA.

If you want to charge your EFDELTA under an environment with an ambient temperature between -20°C – 0°C, please use your EFDELTA to power an electronic with a voltage over 500W for over 10 minutes to warm up EFDELTA before charging it.


◆What is the lifespan of EFDELTA(Under normal use and maintenance)?

After 800 Cycles of use, DELTA's capacity will drop to 60%. However, the lifespan of a battery varies considerably, depending on how it is used, how it is maintained, the ambient temperature and other factors.


◆How should I store and maintain my EFDELTA?

Please keep your EFDELTA connected to a power source (solar panel or wall socket) to help prolong the battery life and ensure your EFDELTA is charged and ready for use anytime. If you cannot keep your EFDELTA connected to a power source during storage, please fully charge and discharge the battery at least once every 3 months to maintain the battery health. Also store your EF DELTA in a cool, dry place.
