I have a 200L, it is a great machine.

The cable that comes in the box with the B300S is P150D on both sides, since that is the connector on both the B300S and the AC500 (150 Amp rating). The B300 and AC300 have the P090D connector (90 Amp).

It’s a beautiful thing isn’t it. On a good day I can make and store 10kWh with my 1600W of panels.

The Bluetti products with selectable UPS modes will do this. I’m running part of my house on an AC300 right now in this way with it set to PV priority UPS mode.

Most Bluetti products will wake up with solar input then power themselves off a bit after it goes away. Inverter is never on and consuming standby power unless you turn it on.

Yes, read post 4 of this thread. The AC300 NEEDS a B300 to talk to. The B300 and its BMS aren't an optional accessory, at least one attached is mandatory to have the AC300 work.

Math on their published load and runtime claims.

Here is some math on Honda inverter generators I did some time ago based on Honda's run time claims at 1/4 and full load: The Honda EU7000 burns 5.1 gallons of gasoline in 6.5 hours at 5500 W to make 35.75 kWh at 7.00 kWh/gal (fuel injected!) The Honda EU6500 burns 4.5 gallons of gasoline in...

I am not seeing this on mine. What edition of HA are you on? I'm running 'HA core' on a Pi.

That was vague, not this site. one of the HomeAssistant forums. I'm happy to share what you need to duplicate.

I spent some time with HA today, following other threads on the topic and have mapped individual cell voltages for my B300's into HA. love it.

Reviews on that 5-20 to L14-30 adapter cord indicate that it doesn't power both the X and Y blades on the L14-30 side. you may want to take a multimeter and poke through your whole setup.

Three of those in series on each of the two MPPT inputs would be a good setup. 123Voc so some headroom for cold weather on the 150V input. 1110W nominal x2 = 2220W total. Yes you could overpanel by doing another three in parallel (for 3S2P) on one of both controller inputs. It wouldn't make...

They are pretty responsive, I hope you see improved results. Forecast is neat when it works. Yesterday expected 9.3kWh, I got 2.5 due to clouds rolling the wrong way. Today is 9.7 and I need it!

#1 is what firmware fixed for me.

What is your indicated battery SOC? Mine throttles to AC output +~550W when it gets to 91%, even with the new firmware.

Contact Bluetti support, there is a firmware update that helps. Big load changes still sort of upset the MPPT on mine and cause it to hunt around for a few seconds, but it doesn't throttle like that anymore.

No. Make sure the voltages match very closely, like +/- 0.2V. Be EXTREMELY careful, you are dealing with hundreds of amps of available current.

I have not sorted the difference in those. Something I have deciphered...I think on the AC300 that the internal power sensor 1 is Watts, and sensor 2 is VA.

That's all the built in controllers on the head unit will take. You can however add solar to the B300 battery, it will take 200W directly connected, then up to 500W via a D050S Charge enhancer (external MPPT) connected to the AC adapter charge port. For up to 700W total input directly to each...

The AC300 does not know the external pack is there, there is no BMS/computer connection, only the power leads. It properly shows the B300 battery, which is same voltage and being augmented with the external in parallel, in theory they are all at the same charge level.

I’m still happy with my two since balancing them.

I bought the P90D to P150D adapter cable for my testing. One end connects to the AC300/B300, the other end an AC500/B300S.

If it’s sat for a bit it may be out of pack balance. I’d just plug it in and leave it overnight until it stops taking power. Then discharge at low load, like 50-100W running a fan until it shuts off, plug back in overnight.

The Bluetti AC180 Does not support WiFi. It is bluetooth (proximity) access only via the app.

For my AC300 I created a new entity for PV2 which is the subtraction of the reported PV1 input from the total PV input. Works a treat.

Welcome. I’d be happy to help when you get to it if there are questions, feel free to PM.

I used a 60V/5A adjustable/lab power supply. It worked well.

The new little Bluetti, the AC2A, does not exhibit these issues in UPS mode and is pretty solid. They have learned.

Agree. Every surface had a thick polished heavy lacquered look to it to me, was kind of strange seeming. I think the cooktop was induction at least. They probably scraped the label off something else and stuck their own on. I didn’t look too close at the name on it and did not notice that.

They told me the motor assist is only for self-parking/hitching, and for starting assistance up to 10mph, where it goes into freewheel. It did look heavy for its size.

I walked through it too, super nice and polished, it certainly should be though for 100K. It had some really wide tires for a trailer, probably to avoid going to double axle. They said it had a 1kW array on the roof.

@johnnysweekends @Jasonoid @minutemanprep The guy at the right escapes my jet lagged and sleep deprived memory at the moment, he does RV related things. I also ran into: Scott @EverydayHomeRepairs , @everydaysolar Ray @diySolarPowerFunWithRay

It was huge! They also had a matching bulldozer.

Did you see them giving rides up and down the stairs on the dog? It was hilarious. Might have been a different company, I remember the head of the dog looking different.
