Solid, reliable back-up

This is the fourth B300 I've purchased to add to my AC300 system. All batteries are working perfectly. The build quality is excellent and I can now cope with the frequent power outages that we get here.

B300 battery

Large capacity extension battery which can power my house for 6 hours . Love the modular design. Sturdy and strong and stacks easily

Does exactly what they said it woukd6

Brilliant buy so far, quiet, powerful and charges quickly.

B300

Superb quality, I have 4 of these now with my new AC300, which gives me enough power to run my utility room with my boiler, washer, dryer, fridge and lighting.

more battery space

my second b300. giving me more flexibility to store the power i need to keep me running off grid.

Great Value & Simple to use

Easy to connect to the ACMax 200 though connections would have been easier on the opposite side like the smaller b230 but when setup on shelving, its no trouble.
The added Solar charge option is ideal and ensures the battery turns on with the ACMax for simpler charging.

Brilliant bit of kit and already saving me money!

I have the AC300/B300/PV350/EB70 and it is a great bit of kit! I charge it up during my cheap 5 hour window on my energy tariff and then run the system during peak saving myself £1.00 a day in energy costs and even more if the solar panel pulls in more energy for free! In just a few weeks I’ve reduced my ‘peak time’ energy use by 6.7% so my first 3kWh battery will be paid for itself from savings in 5 years, or less depending on how much solar we pull in! Great way to give us energy security and help the financial burden in the years to come with ever rising energy costs. I think we will never see the days of peak time energy at a rate of 12p per kWh (or less) ever again so these are a no brainer. I can’t have a ‘full house’ install tied to the meter as my home is rented so this gives me the next best option of securing savings and ensuring I have energy security.

Easy to use, Versatile and powerful.

I am so happy with this expansion battery. This doubles the power of my system. BLUETTI products are incredible.

Loving it so far. Great product
