    Is it safe to have the Bluetti DC Charging Enhancer (D050S) connected to my AC200MAX all the time?

    I've had a D050S connected to my 200MAX + B230 for over 8 months with no issues from the Charge Enhancer. I do note that, once fully charged the system seems to allow the battery to discharge to 98% and then start charging again. I was under the impression the system would simply allow the...

    Howdy! Considering Bluetti AC200 Max

    EcoFlow just relaesed the Delta 2 with lifepo batteries so it might be worth a second look. FWIW I got 4x120w small panels and then got full-size 4x315w panels.

    Where is serial number?

My concerns are the mechanical switch and how long it will last. And the potential for it to stick back and forth is the solar is...

    Bluetooth AC200 Max firmware update?

    Is there the same issue for the B300? I noticed in the Bluetti promo video they explicitly call out the charging issue for the B230 but didn’t mention the B300

    Reversed UPS , Mains power after low battery ?

    I'm in a similar boat I want to add in my fridge and freezer (total max draw is about 350W all up) into my solar generator system and they need to switch back to AC when the battery is drained. I'm renting so don't want to mess with the mains and just run extension cables. I was initially giving...
