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


It allows users to produce their own energy, to obtain certain economic benefits.
When solar power 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 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 old installations 

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

View daily and total consumption status


état de consommation journalière et totale


You can look at the consumption coming from your installation

 Graphique de votre consommation

There is an asymmetry between our electricity needs and the production of our solar installation.

As can be seen, theohybrid ndurator allows via batteries, storage of unused production during the day (red line down).

So you benefit in the morning and evening from the energy produced throughout the day (red line upwards).

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 recharge.

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

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

 Configurable battery charging range

HorlogeAt 8am on 20/09 the battery east to 30% of its capacity of charge, the inverter will engage the recharge of the battery, the recharge is carried out at times configurable from the inverter, so we can choose the time slots where we decide to recharge the batteries, once 100% the inverter no longer sends the energy to the battery but sends the unused energy to the public grid. From 7pm, the battery begins to drain. We then use the energy of the battery to meet our energy needs.

Connection to Pylontech US-2000 C


CAREFUL: When connecting your Sermatec inverter to Pylontech US-2000C battery, cut the White/Orange, Orange, and White/Green cables.

Connect the cable to the RS485 port on the master battery.
