Hi all,
New to the community and am trying to charge a 48volt portable power station with a charger 1
It has a 12-150 volt dc input range with a 15 amp max for the PV input.
It seems to start off okay and builds up to around 500w and shortly afterwards drops to zero with a 4 red light flashing sequence which equates to a input under voltage.
Can anyone suggest what may be happening and possible solutions
TIA
What is your source to the Charger 1?
Are you using the OEM cable for the Charger 1?
Solid red means input undervoltage, but 4 flashing every 1 second means OUTPUT undervoltage. For 3rd party power stations that have a high VDC in your case 12-150 you may need to adjust the voltage. I believe the default is 27V, but you can try 56V in the Bluetti app. If that doesn’t work, make sure the cable you are using for your PV input is rated to handle the voltage range. I know on the Ecoflow units you have a high PV and a low PV. The high PV operates at 30V minimum so the default of 27V won’t fly. You may need a proper cable to handle the voltage curve of the PV port you are plugging into the power station from what I read.

Thanks for your suggestions. I ran it at 56 volts and it gave the same result. I kept an eye on the vehicle battery voltage and even though the vehicle was running admittedly at idle it steadily dropped until the fault. Then it returns to 14.3 volts and start the cycle again. It tried it holding higher revs to provide more input from the alternator but same result. Im waiting for a response from Bluetti !
I am using the cable kit supplied with the charger 1
Ps. I did mean to say output undervoltage.
On the cable topic I have the cable connection which comes with the unit and a 30cm mc4 to pp30 anderson to suit my power station
To ensure your wiring is correct, flip the 60A breaker switch to OFF position. On the app DISABLE the charge slider. Now turn on the vehicle, and flip the breaker switch to the ON position. The LED indicator on the charger 1 should blink green then go steady green. You haven’t enabled charging but at least you know that you don’t have any ground faults or wiring issues.
Lastly, in the charging profile (select charging voltage) choose CUSTOM and play around with the voltage. Since you have a 12V battery you can use the entire 15-56V range. The YouTube video recommends for 12V to be within the 15-27V range. So you can try that. The app defaults to 27V which is MINIMUM for a 24V battery. Hopefully you aren’t one of the 5% that this doesn’t work for. From my understanding the initial voltage reading from alternator will push out around 14.4-14.6 as it regulates it, so if you are checking it from a multimeter that’s normal behavior.
I noticed when I connected my C1 to my 4x4 to power an AC180, it had issues charging the power station. With no charge.
I tried the initial 27V setting, changed it to 40V and then to 56V with no change at output. My 4x4 has a smart alternator.
The C1 cable was not installed fully, but connected to the Start battery using the OEM cable, then to the C1 and on to the AC!80. This was a static test at idle in my driveway.
The result may be totally different when driving compared to idling in the driveway, but I never intended the C1 to be fully installed. Therefore it’s hard to test with several metres of cable flapping around on the outside of the vehicle when driving.
What I can say is, I then used a 12V - 100Ah LFP deep cycle battery to power the C1 and it worked perfectly at all set voltages. This was my primary reason for buying it as none of my 6 power stations have dedicated expansion battery ports. Sitting in my dining room, using a short cable I made, from the 100Ah to the C1, set at 56V, I got a constant 556W output.
Therefore, excepting a fault, I see my issue as being on the supply side, which caused an issue at the output. Your issue may be for the same reason.
Thanks for the responses, see attached screen shot from Bluetti help. Looks like I may have a charger1 up for sale. Unless the smarter than me people come up with something!
What doesn’t make sense to me is my power station will accept volts and amps from a solar panel no problem with no (cc) or (cv) in sight?
