With the development of the energy storage market, traditional grid-connected inverters have been unable to meet customer needs.
Depending on the application scenarios, there is a need for network-connected features, as well as off-grid functions, particularly in the home energy storage market. In network-connected and off-grid states, the inverter must provide energy to the load.


It allows users to produce their own energy, to obtain certain economic benefits.
When solar energy is sufficient, the inverter draws energy from the PV station to power consumers, and the remaining power will charge the energy of the batteries. The inverter automatically powers the battery charge.
When the battery's energy runs out, the inverter takes power from the grid, powers consumers and recharges the battery.
This all-or-nothing network inverter can be installed indoors or outdoors.

New Sermatec: AC Coupling

Maximize your self-consumption, even for older facilities 

PV inverter connected to the network is connected to the output of an inverter and then to a hybrid. Photovoltaic energy is first used to power the charges, then to charge the battery, and any excess photovoltaic energy can be re-injected into the grid.

Daily and total consumption status


You can look at your consumption from your facility

 Graph of your consumption

There is an asymmetry between our electricity needs and the production of our solar installation.
As can be seen, theoHybrid nduleur allows via batteries, storage of unused production during the day (red line down).
So you enjoy in the morning and evening the energy produced throughout the day (red line up).
The yellow highlight indicates the production of energy via solar panels.
The electricity consumption used on the network is shown in blue (blue line down).
The reinjection of electricity produced by the panels is injected onto the network (blue line up).


We will observe a consumption on a day Whole 

At 04:00 we use the public grid for our energy needs

At 10:00 a.m.: the panels produce 3002 W and the batteries recharge.

At 2:35 p.m.: The battery consumes 10.60 W and 2665 W is injected into the public grid.170 W.

At 9:00 p.m.: Using the battery to meet our energy needs.

Steps to change the language of the application

Setting up Wi-Fi on your inverter


Step 1 and 2 wi-fi configuration



European Server Settings 

Come in in the server's IP box, and 19042 in the server's port box.

Send the settings by tapping Proceed;
Make sure that all the inverter's LEDs turn off and restart. This will confirm that the setting has been taken into account



Step 3, 4 and 5 wi-fi configuration




Setting the router 

Select the working mode as a way to connect to the platform, enter the router's name and password (the router's name and password can only contain English characters or numbers),
Send the settings by tapping Proceed;
Make sure the inverter's LEDs turn off and restart. This will confirm that the setting has been taken into account.
