Growatt MID20KTL3-XH AFCI Inverter 20kW 3PH 2MPPT

MOD TL3-XH series inverters are versatile, highly efficient transformerless 3-phase inverters.
GROWATT products meet all European standards and norms and have the necessary certifications, including TUV.
Three-phase inverter with battery output - cooperating with Growatt batteries.

Photovoltaic inverters cooperating with batteries

  • TL3-XH photovoltaic inverters prepared to cooperate with batteries is a novelty that Growatt New Energy is introducing to the Polish market.
  • This system can be built as an emergency power supply system, so that in the event of a power outage from the grid, the devices in our home will be able to work without problems.
How do the GROWATT MOD TL3-XH photovoltaic inverters work?
  • Dedicated modular batteries and other products such as the Growatt GroHome are designed to increase the energy consumption of photovoltaic panels in real time.
  • The Growatt GroHome can, for example, be used to control the operation of a heat pump based on the product from the photovoltaic panels.
  • The reason for this is balancing with the power industry, which in other countries is no longer beneficial from year to year.
  • This is a result of the state of the grid, which, due to its old architecture, has limitations when working with a large number of photovoltaic installations.
  • To the rescue come energy storage systems and products to maximise auto consumption.
  • This is a policy that Growatt New Energy introduced earlier this year and will continue to follow for the next couple of years.
