Understanding your GoodWe working modes

Understanding your GoodWe working modes

Your GoodWe system can operate in several different modes, each designed for a different goal. The mode determines how your system prioritises solar energy, battery storage, and the grid. You can view and change your working mode in the SEMS+ app under Device settings.

Self-Consumption Mode

The standard mode for most households. Solar generation powers your home first. Any surplus charges the battery, and any remaining excess is exported to the grid. When solar isn't enough, the battery supplies your home. The grid steps in only when both solar and battery are depleted.

Best for: Most households looking to reduce electricity bills and maximise use of their own solar energy.

Backup Mode

Recommended for areas with unreliable grid supply. In this mode, the system keeps the battery charged to a set backup level at all times. If the grid fails, the inverter switches to off-grid operation and the battery powers your backup loads without interruption. When the grid returns, the system switches back automatically.

Best for: Households in areas prone to outages, or anyone who wants reliable backup power.

TOU Mode (Time of Use)

Lets you buy and sell electricity strategically based on peak and off-peak electricity prices. For example, you can set the battery to charge from the grid during cheap overnight periods, then discharge during expensive peak periods to reduce your bills.

Best for: Households on a time-of-use tariff who want to actively manage electricity costs.

Delayed Charging Mode

Designed for areas where grid export is capped or limited. You can set a peak power limit so that any solar generation above the export cap goes into the battery rather than being wasted. You can also set specific PV charging windows.

Best for: Households with grid export limits or solar curtailment requirements.

Demand Control Mode

Primarily suited to commercial and industrial setups. If total power consumption exceeds a set quota in a short period, the battery discharges to cover the excess and avoid peak demand charges.

Best for: Commercial properties with demand tariffs.

Off-Grid Mode

When the grid fails, the inverter automatically switches to off-grid mode. During the day, solar powers your loads and charges the battery. At night, the battery discharges to keep your backup loads running.

Note: Do not operate in pure off-grid mode if your system is not connected to a battery.
