Note: The absence of AC breaker will lead to inverter damage if an electrical short circuit happens on grid side.

1. Use separate AC breakers for individual inverters.
2. On the AC side, an individual breaker should be connected between the inverter and grid but before any loads.

Requirement of AC cable connected to On-Grid and Back-Up side

• Make sure inverter is totally isolated from any DC or AC power before connecting AC cable.
• The choice of AC cable needs to meet both the outside diameter and conduct core section requirements. Please refer to the table for selecting the AC cable.
• Neutral cable shall be blue, line cable is black or brown (preferred) and protective earth cable yellow-green.
• For AC cables, PE cable shall be longer than N&L cables, so that if in any case AC cable slips or taken out, the protecting earth conductor will be the last to take the strain.

Back-Up wiring connection process is as below Note: On-Grid wiring connection process is as below

Back-Up wiring connection process is as below

Note:

1. An external AC breaker (≥32A) is needed for Back-Up connection to be isolate when necessary.
2. The absence of AC breaker on Back-Up side will lead to inverter damage if only electrical short-circuit happened on Back-Up side. And Back-Up function cannot turn off under On-Grid condition.
3. Make sure the terminal cover is rightly locked onto the terminal.

Declarations for the backup function

The back-up output of inverters have over load ability.
For details please refer to the technical parameters of the inverter section.
And the inverter has self-protection derating at high ambient temperature.
The below statement lays out general policies governing the energy storage inverters.

1. For Hybrid inverters, the standard PV installation typically consists of the connection of the inverter with both panels and batteries. In case of systems not connected to the batteries, the Back-Up function is strongly not advised to use. GoodWe shall not cover the standard warranty and be liable for any consequences arising from users not following this instruction.
2. Under normal circumstances, the Back-Up switching time is less than 10 ms (the minimal condition to be considered as the UPS level). However, some external factors may cause the system to fail on Back-Up mode. As such, we recommend the users to be aware of conditions and follow the instructions as below:
   • Do not connect loads if they are dependent on a stable energy supply for a reliable operation
   • Do not connect the loads which may in total exceed the maximum Back-Up capacity
   • Try to avoid those loads which may create very high start-up current surges such as Inverter Air-conditioner, high-power pump etc.
   • Due to the condition of battery itself, battery current might be limited by some factors including but not limited to the temperature, weather etc.

Acceptable loads are shown below:

The inverters are able to supply over load output at it’s Back-Up. For details please refer to the technical parameters. And the inverter has self-protection derating at high ambient temperature.

• Inductive Load: 1.5P non-frequency conversion air-conditioner can be connect to back-up side. Two or more non-frequency conversion air-conditioner connect to Back-Up side may cause UPS mode unstable.
• Capacitive Load: Total power <= 0.6 x nominal power of model. (Any load with high inrush current at start-up is not accepted.)
• For complicated application, please contact after-sales.

Note:
For a convenient maintenance, an DP3T support could be installed on Back-Up and On-Grid side. Then it is adjustable to support load by Back-Up or by grid or just leave it there.

Questions & Answers (Q & A)

About the Wi-Fi Configuration
Q: Why can’t I find the Solar-Wi-Fi* signal on mobile devices?*
A: Normally the Solar-Wi-Fi signal can be seen immediately after inverter has powered up. However, the Solar-Wi-Fi signal will disappear when the inverter connects to the internet. If changes to the settings are required to connect to the router for changes. If you cannot find the Wi-Fi signal or connect to the router, please try to reload the Wi-Fi.
Q: Why can’t I connect to the Solar-Wi-Fi* signal on my phone?
A: The Wi-Fi module can only connect to one device at a time. If the signal is already connected to another device at the same time, you will not be able to connect to the signal.
About Battery Operation
Q: Why does the battery not discharge when the grid is not available but it discharges normally when the grid is available?
A: On the APP, the off-grid output and backup function should be turned on to force the battery to discharge under off-grid mode.
Q: Why is there no output on the backup side?
A: For backup supply, “Backup Supply” on the SolarGo App must be turned on. In off-grid mode or when the grid power is disconnected, the “Off-Grid Output Switch” function must be turned on as well.
Note: When turning the “Off-Grid Output Switch” on, do not restart the inverter or battery. Otherwise, the function will be switched off automatically.
Q: Why does the battery SOC suddenly jump to 95% on the Portal?
A: This normally happens when BMS communications fail when using lithium batteries. If the batteries enter float charge mode, the SOC is automatically reset to 95%.
Q: The battery cannot be fully charged to 100%?
A: The battery will stop charging when the battery voltage reaches the charge voltage set in the SolarGo App.
Q: Why does the battery switch always trip when it starts up (lithium battery)?**
A: The switch of the lithium battery trips because of following reasons:

1. BMS communication fails.
2. The battery SOC is too low and the battery trips to protect itself.
3. An electrical short-circuit has occurred on the battery connection side. Alternatively, for other reasons, Please contact the after-sales department.

About SolarGo Operation And Monitoring

Q: Why can’t I save settings on the SolarGo App?
A: This could be caused by losing the connection to Solar-Wi-Fi *.

1. Make sure you have already connected to Solar-Wi-Fi (make sure that no other devices are connected) or to the router (if Solar-Wi-Fi is connected to the router). The APP homepage shows the connections.
2. Make sure you restart the inverter 10 mins after you have changed any settings because the inverter will save the settings every 10 mins while operating in normal mode. We recommend that parameter settings be changed when the inverter is in wait mode.

Q: Why are the data displayed on the homepage different from the param page, like charge/discharge, PV value, load value, or grid value?
A: The data refresh frequency is different, so there will be data discrepancies between different pages on the APP as well as between these shown on the portal and APP.

Q: Some columns show NA, like battery SOH, etc. Why does that happen?
A: NA means that the App has not received data from the inverter or server because of communication problems, such as battery communications and the communications between inverter and the App.
About the Smart Meter And Power Limit Function

Q: How to activate the output power limit function?
A: For the inverter system, this function can be activated by following these steps:

1. Make sure the Smart Meter connections and communications are functioning correctly.
2. Turn on the export power limit function and set the maximum output power to the grid on the APP.
   Note: Even if the output power limit is set to 0W, there might still be a deviation of a maximum of 100 W when exporting to the grid.

Q: Can I use other meter brands to take over from the Smart Meter in the system or to change settings in Smart Meter?
A: No, because the communication protocol is integrated into the inverter and Smart Meter, other meter brands cannot communicate. Also, any change to the manual settings could cause a meter communication failure.
Q: What is the maximum current allowed to pass through the CT on the Smart Meter?
A: The maximum current for the CT is 120A.

Other Questions

Q: What kind of load can I use to connect to the backup side?
A: Please refer to 2.4.3 On-Grid&Back-Up Connection section.

Q: Will the warranty of the inverter still be valid if, for some special conditions, we cannot follow 100% of the User Manual instructions for installation or operation?
A: Normally we still provide technical support for problems caused by not following the instructions in the User Manual. However we cannot guarantee any replacements or returns. So, if there are any special conditions for which you cannot follow the instructions 100%, please contact the after-sales department for suggestions.
