Page 9: Wifi Setting
Before turning on the power switch, the main battery switch must be closed. Touch the power switch, and all the indicators Power on will self-check and light. (if the gird power or PV has been connected in advance, the power will automatically turn on). In emergency case, the system can not work normally, can press the power button for more than 10 seconds, the system will Reset... - Page 10 Set between 0-11 hour and 0-59 minute. For example, the setting is 01:20, it means the 1 charging period is 1 hour Charge period and 20 minutes (if the timing mode is started, but don’t 00：00 want it charge,change the charge period to 00:00 directly, then 1 charge period will not work) Set between 20%-100%;for example,set as 50% it means...
- Page 11 (This charging here refers to the mains charging instead of solar charging.For solar charger,it will be automatically charged as long as there is solar power). Set between 1-40A. For example：10.0 means the charge current of 2 charging period is 10A. (This charging here Charger current of 10.0 refers to the mains charging instead of solar charging.For...
- Page 12 discharge,change the discharge period to 00:00 directly, then 2 discharge period will not work). Set between 20%-100%;for example,set as 30% it means the system will stop discharge battery power to the grid (feed to grid) once the battery SOC reaches to 30% in the discharge period.
