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 from the batteries. The inverter automatically powers the battery charge.
When the battery energy is depleted, 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 old installations 

The Sermatec hybrid inverter is connected in parallel to the grid inverter. Photovoltaic energy is first used to power the loads and then to charge the battery, and any excess photovoltaic energy can be fed back into the grid.

View daily and total consumption status

You can look at the consumption coming from your installation

There is an asymmetry between our electricity needs and the production of our solar installation.
As can be seen, theoHybrid nduleur Allows via batteries, the storage of unused production during the day (red line down).
You therefore benefit in the morning and evening from the energy produced throughout the day (red line up).
The yellow highlight indicates the production of energy via the solar panels.
The electricity consumption used on the network is indicated in blue (blue line down).
The reinjection of electricity produced by the panels is injected into the network (blue line upwards).

We will observe a consumption over a day Whole 

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

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

At 2:35 p.m.: We produce (3170 W), the battery consumes 10.60 W and we inject 2665 W into the public network.

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

Visualize the charge level of your batteries 

Configurable battery charging range

At 8am on 20/09 the battery east at 30% of its capacity charging, the inverter will start recharging the battery, charging is done at times configurable from the inverter, so you can choose the time slots where We decide to recharge the batteries, once at 100% the inverter no longer sends the energy to the battery but sends the unused energy to the public network.  from 7pm The battery starts to discharge / we use the energy of the battery to meet our energy needs. From 7pm The battery starts to discharge / we use the energy of the battery to meet our energy needs.

You can find the installation steps in the technical sheets & documents. "Sermatec-FR param Manual"

Connecting to the BMS SC0500 module

CAREFUL: If the Sermatec is connected to the BMS SC0500 Pylontech, cut the White/Orange, Orange and White/Green cable.

Connect the cable into the RS485 port on the BMS.
