Hello,
I am looking for some help with the AC200L. So far I have been happy with it. It can run most everything on my RV and solar charge at 1200 watts. There is a limitation that I have found that I would love some help with. My RV air conditioner pulls 1400 watts while it is running. That means that if the sun is perfectly over the panels and I am getting the full 1200 watts, I can run for about 8-10 hours before the power station goes flat. The bummer is that clouds and sun angles and all that get in the way of a constant 1200 watts of solar, so I average around 800-900w on a sunny day. Pretty good, but that means the battery goes flat a lot faster.
I use the power station to power the RV Air conditioner mostly when I am driving down the road…
Brilliant idea! What if I install a small (pure sine wave) inverter to supplement the solar and limit the draw off the inverter through the Bluetti app to 700 watts. This will keep me from overloading the alternator and keep the cab cool while never discharging the power station (on a sunny day).
Okay, so I buy said inverter, hook it directly to the battery, fire up the engine, test the voltage to make sure the alternator is working, and hook up the inverter to the AC power input on the Bluetti. Grid connection lights up and it starts pulling 700 watts from the inverter! cool. Then I go to fire up the air conditioner, a few relay clicking sounds happen, and the power station shuts off the ac input and output. Something overloaded…
It seems like I want the power station inverter to continue to draw from the internal battery, but the power station wants to passthrough the draw to the inverter, which then overloads the inverter and then overloads the power station inverter.
Is there any way to disable the passthrough functionality on the Bluetti AC200l? So when I plug in the power station, all it does is start charging the batteries in the power station? This way the Bluetti inverter will keep powering the RV air conditioner and the small inverter connected to the car 12v system can be shielded from the start up load on the air conditioner and just charge the bluetti at 700 watt limit.
Hi @Thor, It seems that you are using two inverters, one of which is our AC200L, and the other is from another brand. Is that correct?
If you want to disable the bypass mode, please turn on the Time Control UPS mode and set the current time as the discharge period. This way, the load will not be bypassed, and charging will not be possible either.
Thanks for the response. Sounds like I need to clarify. I want the power station to charge both with solar and grid without passing the load through to the grid. Attached are some diagrams showing what is happening. Two important things to note while interpreting this diagram. 1. The AC200l has no problem running the air conditioner without the grid connection. The power output from the 30A socket is enough. 2. If I plug the power station into the household outlet, it can work as I intend and will run the air conditioner but draw a reduced amount of power based on the charge limit (set to 6 amps). I believe it works because the household outlet can handle the momentary power demand of passthrough as the relay clicks over and then dials back the current to 6 amps.
Ok try this…
Go into Advanced Settings…
Adjust the Max Grid Input down to the 6Amps.
It should work… but it will draw down your AC200L battery…
I think that is what you have already done…
I think you are asking if there is a way to stop the air con overloading the supply to the AC200L… that is the only way I think will work… Not sure if power lifting will help…
I suspect it will be a compromise… I know from the loads I run, an aggressive fan speed on my heater setting will trip the AC200L, but starting it again won’t…
As a suggestion try starting the Aircon without the input into the AC200L turned on… and with the 6 Amp grid input set, then turn on the inverter feeding into the AC200L… The challenge is the AC200L can’t predict the load of the Air con… thus it “just” passes the spike through to the source… which can’t handle the spike and it then shuts off… the AC200L goes WTF… and shuts down…
I suspect there is a better way of handling these spiked… but I am not an expert in this area… I am only a drip under pressure!
Cheers,

Hi @Thor, Thank you for providing the detailed information. We believe this is an overload caused by exceeding the load range.
Please note that for some machines with built-in compressors or condensers (such as fridges, air conditioning, pumps, and freezers), the surge power will be 3-7 times higher than the rated power, and it will keep several seconds after it is just turned on. Then we will check if our machine can afford it or not. Please consult the supplier of your device for more information.
The starting current of your load is too high, making it impossible to operate. You can use a larger power station to power the air conditioner.
Thanks to @Apheres for the suggestion, which is very helpful.
