Grid Voltage Low on AC300+B500K

Product Discussion BLUETTI Apex & AC Series
1

Hi @BLUETTI or @BLUETTI_CARE, I’m from Ukraine and experiencing frequent 058. (Grid Voltage Low) errors on my AC300 + B500K due to unstable grid voltage (often around 180-200V because of the current situation). Standard firmware and Grid Self-adaption don’t solve the problem as Grid Self-adaption just can’t be enabled. Could you please provide a custom firmware with adjusted lower voltage thresholds or suggets how should I charge my device?

Serial number AC3002313002115675
Communication BoardSN IoT2310001507839

IOT v9041.10
ARM v4037.07
DSP v4053.03
BMS v1084.05

Thank you for your support!

Hi Vitalii, I have the same situation and problem. The ONLY decision in your situations - Inverter voltage stabilizer. Brand VOLTER and only Inverter type (yes it’s expensive but believe me - I tried everything and only inverter stabilizer helped me to charge my Bluetti). Grid Self-adaption - not a panacea in such unstable electric environment.

Hi Arvian, thanks for info. Are u saying that stabilizer like Conter MSER 3000 VA-V2/2250W will not help me to charge my AC300. If u know the concrete VOLTER model, please suggest

Got new firmware. Will check if it solved the problem or not and write later.

I’m preferring Volter Smart series (any from Smart models - deviation of stabilisation not more than 0.5%)

It’s a dinosaur )) I know it’s fresh but the technology itself not for the modern devices. Search for the “test for the difference of stabilisation: inverter VS toristor/stepped” on youtube. You will see the difference.
