Yes. The2400 generator supports capacity expansion with B200 PRO expansion batteries, Max suppor 4 expansion batteries up to 10240wh. *2400 & B200PRO: Via1*2+7 PIN Connection Cable

Working time=2048wh*90%/ Operating Watts of Your Device. Note: the actual working time may vary under different circumstances.

No, there are a few varies in performance, chemical composition and longevity in lithium-ion and LiFePO4. Both are safe reliable choice for power station. But LiFePO4 batteries have a longer lifespan, enhanceds afety and increased thermal stability.

Yes. Open circuit voltage: DC16V~60v/10A 500W Max, Total solar input: 500W Max, our 2400W power generator is built in XT60 input port. We recommend ALLWEI 200W Solar Panel.

If your device watts is beyond the 2400W, it will trigger over-load protection. Please press the"Circuit Protector'' Button on the side of the battery to reset the power station.

If the battery is to be unused for a long time (more than 3 months), please recharge it every 3 months to keep the battery power above 50% if you don't use it. (it's recommended to check and charge every 3 months).Store it in a dry and cool place with temperature range between-4°F~140°F, and humidity 20%~85% RH. Avoid contact with corrosive substances, and far from fire and heat Sources

If the ECO mode is on, the AC power will automatically turn off when AC load is 50 W or no load over 4 hours to save power drain.If the ECO Mode is off, to avoid forgetting to turn off the output during use that results in battery consumption, the unit will turn to Auto-Sleep Mode when no device is connected or the connected device is less than or equal to a certain value.When without charging, and the AC & DC & USB outputs ≤2W, the device will automatically shut down after 1 hour.

No, please do NOT store it in a humid environment for a long time.Please store it in a dry and cool place.

Temperature ranges for 2400W power stations are:AC Charging: 0°C-40°C(32°F-104°F); Discharge: -10C-40C(14°F-104°F); Storage: -20°C-60°C(-4°F-140°F).Technically, it can power electrical devices under such situations, but please avoid charging it.

No. lf the battery pack is faulty or evendead, please contact our Customer Service.
