Operation Modes
M-TEC Hybrid inverter has the following basic operation modes and you can configure the operation mode as per your preference
in the App.
In this working mode, when the power from the PV array is sufficient, PV power will supply the loads, battery, and grid by the
following sequence:
Loads>Battery>Grid.
PV power will supply the loads with priority, and secondly charge the battery if exceed PV energy, and then feed to the grid. (You
can set the power to the grid to 0W if the local grid doesn’t allow through APP or inverter display).
When the PV power is insufficient, the battery will discharge to supply loads, and the grid will join in if the battery power is not
enough.
Setting Step: General Mode-->Pmax.
In this working mode, the customer can set the maximum allowable power from grid("Pmax") through App or inverter display.
When the loads consumption less than the Pmax, loads are supplied by the PV array and grid together.
When the loads consumption more than the Pmax, the power exceeded Pmax (cannot be higher than the inverter max output
power) will be supplied by the inverter. PV power will take the priority to supply loads and if not enough, the battery will support
the real-time loading immediately.
* To realize the “Peak Load Shifting” function, the load power that exceeded Pmax has to be within the inverter max output power, otherwise,
the inverter will only output the max power which allowed.
