performance of the inverter, you can change the operating parameters using the Sunny Explorer
software. You can read off the default settings in Sunny Explorer.
Requirements:
☐ A computer with an Ethernet interface must be available.
☐ Sunny Explorer with minimum software version 1.07 must be available and installed on the
computer.
☐ The inverter must be registered in the communication product.
☐ The changes to the grid-relevant operating parameters must be approved by the responsible
grid operator.
☐ When changing grid-relevant parameters, the SMA Grid Guard code must be available (see
Certificate "Order Form for the SMA Grid Guard Code" at www.SMA-Solar.com).
Procedure:
1. Access Sunny Explorer and log in as an installer or user.
2. If required, enter the SMA Grid Guard code.
3. Select and set the required parameter.
4. Save settings.
8.6 Setting the Lower Battery Charge Limit
You will need to set the lower battery charge limit if it is likely that the battery cannot be charged
for a certain time, e.g. in winter due to snow-covered PV modules. This will help to protect the
battery.
Procedure:
• Select the parameter Lower battery charge limit and set the value as follows:
Expected period in which the battery cannot be
charged Lower battery charge limit
≤2 months 0%
2 to 3 months 3%
3 to 4 months 5%
4 to 5 months 6%
5 to 6 months 8%
≥6 months 16%
