Sungrow SH5K+ Check Points

Battery not charging and discharging
After checking wiring correctly and commissioning, if the battery is not charging or
discharging without any error codes showing on the inverter, please follow the below
processes.

Battery not charging

1. Check the SOC of the battery. It is correct that the battery does not charge if the
SOC is 100%.
2. Check whether the PV power is sufficient. The battery will not charge under normal
charge management mode if the load power is more than the PV power. It will not
start charging if the excess PV power is less than 150 W (in which case it will be
exported to the grid instead).
3. Check the settings of battery type and battery capacity.
Note: Key-stop the inverter (select 'OFF' on the LCD screen) first before checking the
settings. For 'other lead acid battery', check the parameter settings according to the
battery specifications.
4. Is the battery in maintenance mode (only for lead acid battery) ? It will show 'maintain'
on the main screen of the LCD.
