BLUETTI 4+

Works decently well, but PLEASE add error clearing to the APP

Badly need error clearing feature. It makes using a Split Phase System Completely Unreliable.

If the units go to sleep at night (with ac output off) My units sometimes wake up at different times in the morning and i get a MCMU Error every morning (If i dont leave the ac on from night before) because the units are configured for split phase function and if the other unit isn't detected, i have to go into my garage and reset the errors on both units. Its insane and happens almost every other day. I cant reset from my phone and it is annoying to not be able to activate my power from the app because the errors stop me.

Also if there can be a feature added to schedule AC output turning on and off that would be perfect too!

Missing time zones and won’t restore output power

Some countries have more than one time zone. USA has 4. There was only one setting for USA, and it wasn’t mine. So all my graphs in the app were off. But after writing this review, Bluetti fixed it in less than 2 weeks!!! So I’m updating my review now. My system is working very well. I have AC300 + four B300. I used a Reliance ProTran 2 transfer switch next to my home’s circuit breaker distribution box to wire 10 circuits in my house. I can independently switch any combo of the 10 to be either Grid or AC300 UPS. I am now in process of putting solar on my roof. So far, I’m only at 600W. But I will go to the 2.4kW that the AC300 can handle. It won’t power my entire house, and I’m not going to deal with the 220V circuits, but this should reduce my bill significantly and get me through power outages automatically. Where I live in California, we have rolling blackouts, safety (wind) blackouts, and many damage (tree on lines) blackouts. So having a UPS system is very nice.

Developer Response ,

We’ve noted your issue and have made optimizations to the time zone settings. Thank you for your feedback. We're committed to continually improving the functionality of our devices.

Wifi doesn’t work anymore.

The wifi connection used to work. True, it would periodically forget settings, and need to be reminded, but it doesn’t work at all anymore. When connected to Bluetooth, the app config screen for wifi asks for a router name and when you try to enter one, it send you to the phone settings for the app settings, but NOT the wifi config! The secret there, is to already have your phone connected to the right wifi hotspot, then the name will be already filled in, and all you’ll need to do is enter the password. At least, that’s how it used to work. Now, despite the app telling you that you have remote control of the device, you don’t. Rebooting the device doesn’t work. Trying to change setting from the device screen doesn’t work. Updating the firmware doesn’t work. Updating the app isn’t an option.

The device itself seems to have been a good investment. The app though, is one of the buggiest I’ve ever seen. I’m hoping that the app doesn’t decide I don’t need Bluetooth connectivity, like it apparently decided I don’t need wifi remote access.
