Customer Reviews
This is my third battery for the AC500; I could use more as I max out the solar output with my 6 x 600w Canadian solar panels. I was an Early adopter of this system (Indiegogo) and had a few teething problems in cold weather; these were eventually sorted with the help of customer support, and the system has worked flawlessly since. Highly recommended.
I have to say this has worked really well, I have 800w solar on the roof and this works well being a continuous cruiser. The only problem I have had is with my EB55 has stopped working which is disappointing. I will do a video on YouTube about the sertup "kitty land rover "
Merry “Bluetti Who Christmas” from us Bluetti
Love my latest addition to my collection!
Easy to expand and connect to the existing AC500+B300s combo.
Now there is more storage power. Both batteries easy to manage on screen on AC500 and mobile app.
I love this system so much more than a home power unit . The stuff you can run out on the road. Fantastic. Keep up the good work.
A B300S was purchased to add to the one that was initially purchased with the Bluetti AC500/B300S combo. So far, no issues have been encountered and the unit has been working great. A nice feature of these batteries is that they not only expand the capacity of the AC500 when they are connected to the unit but they can also act as their own independent provider of DC power (up to 120 watts). A small aftermarket inverter was plugged into the utility outlet on the B300S in order to provide AC power to smaller loads when the battery is disconnected from the AC500 and this has worked well so far. Although very heavy, the battery can be moved around for maximum flexibility. A good overall addition for those with an AC500.
This is my second B300s battery it will double the storage I already have. This is extremely useful due to the UK energy prices. So now I will be able to save twice what I used to save.
The battery itself is a life saver in power cuts. I rate BLUETTI 10 out of 10 for ease of use, it’s plug and play no experience needed.
