| + | - Setting the Absorption voltage for off-grid systems to 56.5V is to ensure the PV Inverter Assistant works properly. Setting this voltage to 56.5V, ie a bit higher than the default 55.2V, prevents the Frequency shift algorithm to lock at 52.7 or 53 Hz, and thereby disabling AC-Coupled PV Inverters. The setting has no effect on the actual charge voltage as used by the inverter and other components in the system, since these are directed directly by the battery via DVCC. | ||

| + | |||
| + | The 'high voltage' | ||
| + | |||
| + | It is easiest to confirm this diagnosis in VRM in the Advanced Widget for the Battery Monitor as it logs this data over time. | ||
| + | {{: | ||
| + | |||
| + | It is also possible to see an instantaneous cell max/min on the GX device in the Menu -> BYD Battery -> Details | ||

| + | |||
| + | To help the batteries balance quickly, keep the batteries fully charged and the system voltage stable until the errors go away. In an ESS system, set it to 'keep batteries charged', | ||
| + | |||
| + | If you are unable to maintain the target voltage to balance the batteries without the 'high voltage' | ||
| + | |||
| + | {{: | ||
| + | |||
| + | Another method that may also help is limiting the maximum charge current that is provided by the solar chargers. In some cases this can allow a better charge without needing to reduce the overall battery charge voltage as much (or at all), by reducing the high current spikes. Charge current limits can be applied at a system level in DVCC - however they will be much more effective and quicker to react to changing conditions if applied at an individual unit level within the MPPT settings in VictronConnect: | ||
| + | |||
| + | {{: | ||
| + | |||
| + | Start with a severe current limit (i.e 50%) and then see if that resolves the issue (while still making sure the system receives a full charge). If the issue is still not resolved, continue to restrict further. | ||
| + | Once the alarms stop, then increase Max Charge Current back to the point where the issue reappears, and then reduce it again by 10%. Note this may also be seasonally affected (if solar window is limited with the changing sun angle). | ||
| + | |||
| + | All of these values can be monitored, and the settings adjustments can be performed remotely with an internet connected system via VRM and VictronConnect Remote. | ||
| + | |||
| + | If it is not possible to raise the voltage or current limits over time, and eventually disable the manual overrides without the alarms reoccurring; | ||
| + | |||
| + | 1: If you have 2 or more batteries in your system, you can try shutting down the system once it is as close to fully charged as possible, and then physically connecting the batteries in smaller groups (or even individually) so that balancing can occur on each individual battery without it being masked by the others connected in parallel. It may help you to see the indicator lights on the battery (if available on that model) to find which battery might be out of balance with the others. You can also monitor this in VRM and the GX device using the min/max cell voltage reporting. | ||
| + | |||
| + | 2: Contact your BYD dealer for further assistance (they can provide additional software to see even more detailed individual cell level data), or assist with other potential solutions. | ||
