Problems During Operation
Problems Solutions
Battery settings on APP
1. For Lithium batteries:
connect Solar-Wifi, check on EzManage APP (Parameter >>>
Battery) if Battery Mode is right for your requirements. If not right,
please change it to the correct mode in “Boost settings”
2. For lead-acid :batteries
All the settings should comply with the parameters of the battery
(GoodWe do not suggest the settings for lead-acid batteries)
1. Make sure the voltage of battery is higher than 48V, otherwise
battery cannot start SBP up.
If battery voltage is OK, but problem still there, please contact
GoodWe after-sales services.
SBP not starting up with ONLY
battery connected
SBP Battery not discharging
when Pmeter<-150W.
Check items:
1. Communication between SBP and EzMeter is OK or not;
2. Make sure Meter power is higher than 150W?
a. SBP/battery will not discharge continuously unless Meter Power is
higher than 150W;
b. If Meter Power is higher than 150W, but SBP/Battery still not
discharge, then please check Ezmeter & CT connection and
direction;
1. Make sure SOC is higher than 1-DOD ;
Or if battery discharged to below 1-DOD, than battery will only
discharge again when SOC charged to 20%+(1-DOD)/2 and SOC
>105%-DOD(if need
restart the system)
battery discharge immediately, customer can
2. Check on APP if it is set as charge time, during charge time,
battery will not discharge (battery will charge preferentially during
coincident time of charge/discharge)
If everything is OK, but problem still there, please contact GoodWe
after-sales services.
SBP/Battery not charging when
Pmeter>150W
Check items:
1. Check if charge voltage is properly set
2. Check if it is set as only discharge time.
3. Check if battery is fully charged or not, or battery voltage reachs
“charge voltage” or not.
If everything is OK, but problem still there, please contact GoodWe
after-sales services.
Q&A (Questions and Answers)
Big Power fluctuation on Battery
charge/discharge
Check items
1. Check if there is a fluctuation on load power;
2. Check if there is a fluctuation on Meter power on GoodWe Portal.
If everything is OK, please contact GoodWe after-sales Services.
Check items:
1. Make sure BMS works OK. if not, please try to restart
SBP, and check the connection (for lithium batteries);
2. Check if EzMeter & CT are connected in the right position and to
right direction as on the user manual;
1. Battery does not charge
About OutPut Power Limit
Cannot see Solar-WiFi signal
on mobile devices
Battery change between
Charge/discharge continually.
Check items:
1. Make sure battery settings are saved successfully;
2. Check if there is a fluctuation on Meter power on GoodWe Portal
If Meter power is stable but problem still exists, please contact GoodWe
services.
Questions Answers
“Battery Activate” function
Only use battery when grid is
OFF
On Portal, SOC has a sudden
jump up to 95%?
1. Can set on APP the max output power to grid;
2. If Output Power Limit set as 0W, then 100w max can be still exported
to grid.
1. Open or close it on EzManage APP;
2. Used to activate battery when battery is discharged completely;
3. Only used when there is no battery charge.
1. On APP, Open off-grid output function and backup function;
2. Set charge time as 00:00-23:59, discharge time as default
1. Happened on Lead-acid battery or when BMS communication NG on
lithium battery;
2. If battery charge current is keep lower than floating charge current set
on APP for 30mins, SOC will be reset to 95% compulsively;
Battery cannot charge to
100%
1. For LG batteries, it will stop charging at SOC 95%. This is normal for LG
batteries.
2. Battery will also stop charging when battery voltage reaches charge
voltage set on EzManage APP.
1. Solar- signal will disappear when SBP is connected to the internet; if WiFi
need to change settings, it can be connected to the customer's router to change.
2. If you cannot see wifi signal and cannot connect to router, then please try
to reload wifi (refer to SBP user Manual)
3. If you still cannot find wifi signal, then restart SBP(disconnect everything
including battery and AC.)
If you cannot find Solar- after all these steps, please contact GoodWe after-WiFi
sales services.
