not recommend this for 4 reasons.
1,DC charging not as description. when i series 3 310w solar panels and VOC is 89.4v. the power is only 292w.
2. service team response very slow and never work at weekend.
they just let you update firmware and change app setting but not work at all.
3. AC2DC and DC 2DC covert not as it's description 94%, only 87%.
that means 2048wh battery power you can only use 1802wh for AC output.
4. the AC/DC charging port is not normal port as other powerstation. you have to pay more morey if you lost.
