Solar inverters convert the DC power from solar panels into AC power that can be fed into a commercial power grid or used by a local off-grid power grid. A standalone inverter can be used in isolated systems where the inverter gets its DC power from batteries charged by solar panels.
What happened?
Tesla has just launched its first standalone solar inverter, which is available in two capacities – 3.8 kW and 7.8 kW. The two "versions" offer two (for the 3.8 kW version) and four (for the 7.8 kW version) Maximum Power Point Trackers (MPPTs).
With the inverters, Tesla Solar Roof and Roof solar modules can equip houses with different energy requirements with an inverter that corresponds to the size of their house.
What does that mean?
The benefit here is that Tesla now has a product verticality that covers the entire solar installation process, providing more control over the cost of its solar systems.
This also means that Tesla is now directly competing with Enphase and SolarEdge for part of the inverter market business.
