I’m using the Oukitel P2001E Lithium 2KW battery system and the app they had a third party create for them. No API, the app doesn’t work reliably – and there is NO support from either company. Here’s my original article covering generators and other stuff as well as the Oukitel.
I started all of this at the beginning of 2026 and I still have the Oukitel in July and there is still no other option than to use the horrendous “Wonderfree” app. I’ve checked all over and no alternatives for the device – right now, chatGPT and I are working on reverse engineering the Bluetooth codes – I’m not holding my breath but the alternative is to continue to suffer the app. No-one from Oukitel Power can be bothered to help.
Should we come up with an alternative to the app I’ll be sure to cover it in here, meanwhile my advice is to go for a Bluetti – I borrowed one while we had no mains power and it is more expensive but the overall experience is WAY better. Also, the Oukitel should support a pair of 400w solar panels for up to 800w out (40v so well within its voltage limits when run in parallel) but I could never get more than 350w or so out of the pair of 400w panels. The Bluetti I borrowed would give up to 600w – and since then I bought a grid-tie invertor to get the best out of the panels, 650w no problem – so why couldn’t the Oukitel “engineers” achieve that I wonder.
Gripe over. More on the grid-tie when I TRULY understand it.
