Hello All,
I'm new to the forum. General Background: Long time IT professional (networking, programming, etc) with home automation experience. I do have some lightweight experience with solar/storage systems (e.g. portable rv solar, solar generators, etc). After many months of researching for backup portable/mobile/flexible solar/storage options I pulled the trigger on a Delta Pro. I think the engineering is second to none with the flexible expansion capabilities along with the mobility/portability and smart/remote integration. They seem to be a forward thinking leading edge company for sure.
To the problem. I have ran a few load tests to verify runtime and have encountered a weird issue. It seems that the lower the wattage load the worse the runtime estimate gets. When I run a high load (e.g. hair dryer - 1600 watts) then the run time on the display is damn close. (See pics of fan test below).
I contacted Ecoflow support about this and they said the bms and battery pack probably needs to be re-calibrated due to being in storage for a long time. They instructed me to cycle it through 3 charging/discharging cycles (100%-0%) to see if that corrects the problem.
My questions are; (1) has anyone else experienced the problem with a new Delta Pro and (2) is this a common problem with other LIFPO4/BMS battery systems?
Any insight would be greatly appreciated!
