Sorry, but I have to say, for my use the B300K is a B I G drawback.
(Letting apart more live cycles etc.)
Not only that it has 10% less capacity confronted with the B300S but there is NO option for DC Input.
In my system AC500 + 6xB300S, there is added a PV modul to each battery
and thus, I have about 2x ca. 1500 W input to the AC500 and 6x ca. 500 W
input to each battery.
I NEED this “extra power” to charge the batteries because in summer
(air conditioner, fruit dreyer) my average consumption is over 20 kWh / day.
I urgently hope that in your future batteries there will be one with
I agree with you. However, I can understand Bluetti’s industrial choice to make a standard brick, without the features (MPPT, DC IN, DC out) and mass-produced, to reduce costs. But I understand you because I am also looking at a B300 rather than a B300K for one of my AC200MAX for the same reasons.
Hi @digait and @Snips1, we completely understand your perspective.
The B300K does have a smaller capacity, as it was designed as a compact battery to be lighter and save space.
At the same time, we enhanced its compatibility so it can be freely paired with more power stations.
We recognize that the reduced capacity and lack of DC output make the B300K less than perfect, and we are working on new accessories and new battery models to better meet customer needs.
The B300/B300s is a mutli-purpose unit with battery, charger DC out etc… It is bulkier and most expensive. I think Bluetti select the B300k as a “pure battery” allow it to be less expensive and smaller. Not everyone who has an AC300/500/Apex300 needs additional DC or solar charging so it is a product line decision. I think they have additional accessories that would allow increased solar input or DC output, which would be good to add to their line without having each battery module to add all those components and cost. The 2.8kWh vs 3kWh isn’t a bit deal, as long as it is less $ and size and weight per kWh.
