2.3.2 ESS Working Modes

The ESS supports three working modes: Maximum self-consumption, TOU, and
Fully fed to grid.
Maximum Self-Consumption
●
●
●
Example:
System configuration: one 5KTL inverter, equipped with the 21 kWh ESS. The ESS
works in the Maximum self-consumption mode.

Issue 01 (2024-03-27)
This mode applies to areas where the electricity price is high, or areas where
the feed-in tariff (FIT) subsidy is low or unavailable.
When the PV energy is sufficient for loads, the ESS stores the surplus PV
energy. When the PV energy is insufficient or no PV energy is generated at
night, the ESS discharges to supply power to loads. This improves the self-
consumption rate of the PV system as well as energy self-sufficiency rate of
the household, reducing electricity fees.
Set the working mode to Maximum self-consumption. For details, see
Setting ESS Parameters.
PV energy usage priority: Powering loads > Charging the ESS > Fed to grid
