DELTA Max can be charged using any solar panels with the same solar connectors and within an input range of 800W 11-100V DC 13A.
1. The standard 400W solar panel supports up to 2 in series. 2. For non-standard solar panels with a wattage lower than 400W, the voltage and current can be used in series at 11-100V DC 10A. They can be connected in parallel or in series, but using solar panels with different wattages is not recommended.
X-Boost has been enabled by default, but you can use the EcoFlow app to turn this function on or off. X-Boost cannot be used in the following situations: (1) AC output is turned on in the charging state (in bypass mode) (2) The X-Boost mode is turned off. X-Boost is suitable for heating and electrical equipment but not for electrical appliances with voltage protection, such as precision instruments. Refer to the actual test to check whether a device is compatible with X-Boost.
The battery types are: Cylindrical 18650, NCM batteries, 10 parallel 8 series, 80 batteries total.
Before updating the firmware, make sure that the device is connected to an AC power source for stable power input. The WAVE 2 works with EcoFlow outdoor power stations, but an XT150 cable needs to be prepared or purchased in advance. Refer to the FAQ for compatible models and connection methods. When powered by a car or solar energy, the power will be lower and the voltage will be unstable, so the device can only work in fan mode. Please use a plug-in battery if you need to use the cooling/heating function. When powered by solar energy in dim environments, please turn on the plug-in battery and connect it to the device to ensure normal operation. A plug-in battery can supply power to the WAVE 2 and DELTA 2 simultaneously. The working temperature range of the WAVE 2 is 5°C–50°C. Please do not use the device outside of this range. When an exhaust hose is used, please do not stretch or bend it excessively to avoid wind resistance, which may affect the efficiency of the WAVE 2.
