Hi All,
i have a Growatt SPH4600 Inverter with 8,375kWp solar panels and a 5kWh LiFePo4 battery.
The communication with the Growatt TPM works (telephone symbol in the display).
Communication with the battery is via CAN and works well (SOC and battery voltage).
Now to my problem:
If the energy from the PV system is no longer sufficient in the evening/night to supply the load in the house, the missing required energy from the battery. The inverter attempts to control the to export power / import power to 0 watts.
But that often doesn't work. The SPH4600 almost always gets over a longer period of time about 20 - 50 watts from the grid, although the battery had enough energy.
Can I change the value in the SPH4600 in the settings or register that no longer to control 0 watts but, for example
regulated to -50 watts (export power). It is better to always export a bit to grid then to import from grid.
Thanks in advance for any tip
