Key Features

Introduction

Portable force bank are nothing novel , but most are relatively small equipment , aimed at providing a bit of mightiness on the move .

The Bluetti AC500 + B300S Home Battery Backup is different : this is a home - sized battery - computer backup arrangement , delivering a minimum of 3072Wh , but going up to 18,432Wh through expansion packs .

With a 5000W output , it can handle any veritable domestic convenience , too . For those that demand a huge amount of off - grid might , this is a muscular and flexible solvent .

Design and features

More storage mean more batteries and bigger sizes . Even so , I was n’t quite inclined for how with child the Bluetti AC500 + B300S Home Battery Backup is . It consist of two unit . The AC500 is the inverter , which converts the DC index from the batteries into AC mains power . This alone weighs 30 kg .

Then , there ’s the B300S battery , which holds a massive 3072Wh of power , and press 36.1 kg . That makes this system only portable for those with the biggest vehicles and , even then , you ’ll want some variety of trolley to move everything around .

In total , up to six B300S batteries can be plug in together to give a total of 18,432Wh , which is probably enough to power the average home for a pair of Clarence Day . That is a great deal of exponent .

The AC500 is associate to the B300S ( or multiple B300S batteries ) via dedicated chunky cables that plug into the side and screw into position .

Most of the outlets are on the AC500 . There are five 13A UK plugs , with the system capable to output a total of 500W. That ’s a Brobdingnagian amount of power : a boiler will top out at 3kW level best , and that ’s about the most demanding gadget that most people will use .

In other words , you’re able to run pretty much a full house from this machine with no limit . There ’s a serge terminus ad quem of 10,000W , so it ’s really very hard to overload this system of rules .

Other battery station , such as theJackery Explorer 1500 Pro , have lower limits and are n’t designed for this kind of whole home backup .

In addition to the standard vent , there ’s also a 32A wall socket , which is designed for connecting the organization as a grid - tied UPS ; that is , letting the Bluetti AC500 + B300S Home Battery Backup take over your home ’s force in the effect of a power cut . In this showcase , the system does need to be project and set up by a qualified electrician .

Otherwise , there are dual 100W USB - C power outlets , dual 18W USB - A socket , and two 3A USB - A ports . Plus , there are two 15W wireless charging socket on top for compatible smartphones .

And , there are two railroad car - expressive style outlets , one 12V and one 24V.

The BS300S add additional ports : one 100W USB - C , one 18W USB - A , and one 12V car outlet .

For charging , there ’s a briny stimulus , which campaign at 15A by default ( 3.3kW ) , although the social unit can be wired in professional to deliver up to 23A of power ( 5kW ) , although that requires using two B300S whole .

There ’s also solar gore support , for up to 3kW of tycoon charging . Combined , that ’s 8kW of input power , although this again requires two B300S building block .

The arrangement can be excite via a 12V input if involve , although this will be slower .

There ’s a main LCD screen , which shows the current load and current input value . This display only shows power stay on as a percentage , not as a prison term remaining , as you get on rival system , such as theEcoFlow Delta 2 .

Via the configurations fare , I could deepen the nonpayment setting , such as changing how the UPS background work , and when the shelling should auto failover . It ’s also possible to set charge and discharging time ( Time Control UPS mode ) , to use cheaper off - peak electricity rates .

There ’s a smart app , which can connect via Bluetooth or Wi - Fi . This shows the current charging rate , and also throw restraint over the banking concern of outputs ( USB , DC and AC ) , letting me toggle them on and off mechanically .

Charging

On mains power alone , the Bluetti AC500 + B300S Home Battery Backup can rescue a full explosive charge in under 90 minutes . With the maximal solar panel remark of 3000W , the organisation can charge in 90 minute , which is impressive . This does , of course of instruction , require you to have maximal sunshine ; on a rainy day in the UK , power is going to knock off and you could take more than a day to fully load this system .

Not to advert the cost . tally four 420W solar panels cost £ 3984 , and that delivers 1600W of major power , so just over half the maximal input . In other words , what the Bluetti AC500 + B300S Home Battery Backup is limit to take is a fortune more than the median owner will yield for .

Performance

The Bluetti AC500 + B300S Home Battery Backup can really handle anything at all . I secure in a standard oven , and run all of my normal tests , using the battery power , rather than briny power . This was perfectly no trouble for this system .

On average , the arrangement can turn tail a standard fridge for three to four day , charge a laptop over one hundred time , smart phone a couple of hundred times and even run a powerful electric heater for at least an hr ; grim - power heaters will run for a few hours . Even running an electric grill ( 1800W ) , there ’s enough power for almost two hours of preparation . These are telling metrics , and show that the Bluetti AC500 + B300S Home Battery Backup really is build to take on typical household usage .

I test the system as a UPS , unplugging it from the mains . Running a computer and projector at the same time , the substitution - over was fast enough that neither lost ability or even flickered . If you have an essential kit that you need to keep running , this system will do the line .

This organization uses a LiFeP04 electric battery , rather than Li - ION . This newer engineering has one main advantage : it lasts for more charge cycles . Battery animation is quote at the turn of cycles it take until the barrage fire is at 80 % of its initial charge . Here , that ’s 3500 cycles .

To get an mind of value , we can work out that after 3500 cycles , the Bluetti AC500 + B300S Home Battery Backup would have store 10,752kWh of power . At the current system price of £ 5499 , it costs 51p to store each kW. present a unit rate of 34p per kWh , it would be around 85p to pay for the electrical energy to commit the unit and stack away it . That ’s a little more expensive than the EcoFlow Delta 2 ’s running play costs , although here , the Bluetti AC500 + B300S Home Battery Backup shop more tycoon and has a far more expensive and powerful inverter . Plus , the price bulge to send packing with extra battery packs .

Go for a organisation with Li - ION batteries , such as the Jackery Explorer 1500 Pro , and the unit monetary value is more expensive : around £ 1.33 per kWh , due to few supported charging cycles .

Of naturally , after 3500 baron cycles , the Bluetti AC500 + B300S Home Battery Backup will stay to work , just that capacitance will continue to diminish . However , my figure liken like - for - like to get a fierce mind of cost per kWh .
