I believe the EcoFlow has a 15 amp limiter built in, with a max voltage of 150 and max wattage of 1600 watts. So you want your voltage as close to the 150 volt limit without going over that will reduce your current as low as possible.
I have a Delta Mini, different I know but it arrived with a car charger cigarette type plug one end and a XT60i [intelligent plug that i see you are using] on the other. As i didn't need the car plug I cut it off and used that cable to connect to the 200watts of solar panels. As I understand it..... the XT60i limits the current the power station can draw from the cars socket preventing blowing a fuse on the vehicle. I at first had the same trouble as you. Starting at 160w but throttling back to only 50watts....... I also have a All powers R600 and I found that it was pulling 180watt from the same panels. The R600 came with a XT60 [WITHOUT THE EXTRA CONTACT] and when I used that lead with the Delta mini it pulled the 180 watts the same. Not saying thats your problem but it worked for me.
What’s the max voltage in from the solar panels for the Ecoflow (VOC). Try Parallel the panels instead of series and bring down the voltage. My Jackery only can take in 30 volts. Just a suggestion. Not sure about your Ecoflow.
Of course it's not, because it uses cheap high frequency, output transformerless inverter technology. You should have bought a low frequency, transformer based portable solar generator if you wanted a unit that lasts.
@@Masterhughesproductions Many major brands use low frequency, transformer based technology including Outback Power, Sigineer Power, Magnum Energy, Victron Energy and Schneider Electric.
so you have 3 matching panels and the 4th panel at the back is different. Am I right..? controllers hate mismatched panels and batteries. That's my guess\thought.
