I created a small solar system on my balcony, consisting of a single 300W panel, 100/20 MPPT, 200Ah LiFePO4 and 2,000W inverter - made for educational purposes.
For few weeks I have been experiencing a specific problem:
During evenings (small or no light), when the converter is off, I am not able to start it. Battery is fully charged but it acts like it was flat = no response. I feel it is the Victron battery charger causing it…
The situation is back to normal in the mornings when more Volts are generated.
Has anyone experienced the same problem? Can there be something wrong with my Victron?
An addition observation: at evenings, in the Victron app I can see the voltage fluctuating (up to few Volts), but no Amps. There is an additional note popping up and disappearing: “why is my charger switched off?”
Please help. Many thanks for help.
