Just saw a comment on amazon on the Charger1 posted 3 days ago about somebody getting G003 on an Astro van - he is measuring 14.5V from the alternator.
Seems more and more that the Charger1 doesn’t work in the 14.x…
Did anybody that ever got a G003 error got it working after getting it repaired ? Still waiting on Bluetti support to send me info for sending them the info so my units get repaired.
@chauffeurdevan I think we may have discovered the fault and that is it can’t cope with the voltage being to high but I would have thought as most campers are vans this would have been something @BLUETTI would want be able to fix with a firmware update to make the voltage range wider aka 12v to 15v
Hi @chauffeurdevan, I believe this service representative might be lacking experience.
Please let us know your service ticket number, and we will contact customer service on your behalf to inform them that there is no need to ask the customer to remove the 6AWG cable.
Our goal is to resolve the issue as quickly as possible, not to create more trouble for the customer.
Hi @Audiotech1986, Please find the screenshot as the voltage range of the Charger 1.
Please rest assured, Charger 1 can tolerate low voltages like 14.25V. There’s no need to install a voltage regulator.
We recommend charging while the vehicle is running.
@BLUETTI_CARE hmmmm if the range is upto 14v then when my alternator peaks at 14.9v when driving then it will be out of range can charger 1 be altered to cope to peak at say 16v without a regulator?
Yep, the Valeo smart 250A alternator in my Mercedes Sprinter is also pretty much running at 14.9 as long as it needs to recharge to vehicule battery. The dealer confirmed me that 14.9v is on specs.
OEM battery in my Sprinter is a Varta AGM battery.
@chauffeurdevan spoke to my local caravan service friend and he said he is looking into a Vistron DC-DC regulator for me
@Audiotech1986 The 12-12/30 dc-dc converters are limited to 380 watts and same price as a charger1 - not sure how the charger1 gonna react if input current is limited. If not there is the new 12-12/50, but this one is already a charger and even more expensive (but only 12v).
On my side, i might just go the victron dc-dc charger 12-48/8 route (seems they are not available in canada, that’s why i did know they existed.) Might be able to charger my power station (in power supply mode i suppose), and also charge my lifepo4 battery (need a victron mppt 100/20-48v if i choose to keep the charger1).
I sent the charger1s for repair/replacement yesterday. Not sure i want to lose more time beta-testing this on my Sprinter, already lost too much time on this, and still no real info on what’s triggering the G003 error.
Hi @Audiotech1986, The peak voltage won’t last long.
Charger 1 was originally designed for 12V starter batteries. As long as the car uses a 12V starter battery, it should be fine.
We don’t think a voltage regulator is necessary—you can use it directly.
Hi @chauffeurdevan, Thank you for sharing this. If you need to arrange priority handling, please let us know your service ticket number.
I appreciate your kind understanding and patience.
@BLUETTI_CARE can you please help explain in lamens terms what G003 error is please if it isn’t the voltage
Your factory battery is an AGM ? If your car/van is built to be used with an AGM battery, bulk charging voltage should be higher. Acid-lead battery BULK charging voltage is 14.2v. AGM bulk charging voltage is 14.7v (on my sprinter, with a factory AGM with smart alternator, bulk is at 14.9v).
Hi @Audiotech1986, A G003 error indicates an input overcurrent. Hope this is helpful.
Thanks to @chauffeurdevan for the explanation.
@BLUETTI_CARE can you explain in lamens terms what “input overcurrent” is? In my mind this means it is receiving too many amps whereas if it is to much voltage it would read “input over-voltage”
This has been so frustrating. I’m having the same issue with my 2023 Sprinter. I was sent another Charger 1 but same problem. Bluetti please help!!!
What’s the voltage you are getting ?
And just for future ref, your sprinter is diesel or gasoline?
how many amp the alternator (M40/200A or M60/250A)?
AGM battery ?
Auxiliary battery installed ?
Hi @Audiotech1986, We would like to confirm whether the input and output share a common ground.
Excluding this possibility, input overcurrent is just one of our conclusions. The underlying cause may be due to a chip malfunction.
Hi @BLUETTI_CARE,
No, the ground (negative terminal on the vehicle battery) is direct to the Charger 1 alongside the live (positive on the vehicle battery) and the same from the charger 1 to the AC200Max aka the positive output of the charger 1 is direct to the AC200Max positive DC input and the negative output of the Charger 1 is direct to the DC input of the AC200Max.
This is the second Charger 1 I have had and really don’t beleive I could be so unlucky to have a second one showing the same fault.
I beleive my VW van is producing to much voltage as stated in previous posts of about 14.9v which is above the 13v threshold of the Charger 1. I have a caravan friend investigating a type of regulator for me to bring that voltage down to within the ratings of the Charger 1 you so kindly shared with me in a previous post
@BLUETTI_CARE @Audiotech1986 It really look like it mightbe too much voltage at the input. Nobody here in this thread have their alternator voltage under 14v, but more in the range 14.1-14.9v.
