Solax Surplus Energy kWh correction

[josiahhiggs]

Using dual Lillygo on 5.9 with TM3 LFP and Solax X1 Hybrid G4.
Solax App reporting on 'battery card' surplus energy is off by one decimal.
TM3 LFP Lillygo reporting 59 kWh and SOLAX_CAN lilygo reporting 59 kWh but inverter app reading 5.9 kWh,.
After discharging 10 kWh from battery, both Lilygo reporting 49 kWh and inverter reading 4.9 kWh of surplus energy.
Battery SOC% is correct when #define BATTERY_USE_SCALED_SOC false
