Hi Folks,
I inquired about this about a year ago.
is there any way to prioritize charging from solar first, and use grid power if solar is not present?
Maybe even SoC% added in there, so it won’t choose to go grid until I’m down to xx% SoC.
Basically, I have excess solar, my batteries ALL charge up to full before 1 PM
If I could make the Bluetti stay around xx% SoC using grid, then do the full 100% SoC from the solar input, that would help me use a LOT more of the solar I have.
Hi @rhousedorf, The BMS system of the AC180 is already set to prioritize solar charging, with AC charging only supplementing when solar power is insufficient. No additional settings are needed for this.
If you want to completely isolate grid charging while solar power is available, we recommend using a smart socket to set the AC charging time.
Based on your description, since your area has good solar performance and can fully charge before 1 p.m., we suggest considering an upgrade to a larger capacity power station or connecting an additional battery pack.
I completely understand your requirements, but currently, this feature is only available on larger models. In the future, we may optimize the app to allow for setting SOC values to select the charging method.
We recommend upgrading to models like the AC200L or AC300, which support SOC setting options.
Dear @rhousedorf Thats not what I experience with my AC180:
With an AC power consumption of 163 Watt, and a Solar input of 238 Watt everything works fine and a battery level of 99%. BUT when I connect to the grid the Grid input tops up to 273 Watt?!
Why? Solar produces enough for usage and charging?
Whats happening here?
I hope you can explain.
Thank you
Hi @Peterm, When the AC180 is nearly fully charged, it will enter a trickle charging mode, gradually reducing the input power. This is designed to prevent overcharging and protect the battery. At this stage, it will automatically switch to AC bypass mode, where grid input is used solely for the load.
If you want to avoid grid charging altogether, you would need to manually disconnect the AC charging cable or use a smart plug to control the AC power connection.
Alternatively, you could upgrade to a newer model with more features and larger capacity, such as the AC200L or Elite 200 V2. These models support customized charge and discharge schedules based on time or energy levels, which may better meet your needs.
