Why can't the smart home panel be connected to a rooftop solar system using AC coupling?

• Smart Home Panel 2 is designed for managing and distributing AC (Alternating Current) power within a traditional electrical system. Rooftop solar panels, on the other hand, generate DC (Direct Current) power. This fundamental difference in current type means direct connection without proper conversion and control mechanisms (like an inverter) is not feasible. • In a rooftop solar system, the DC power generated by the panels must be converted to AC power to be compatible with home appliances and the grid. This conversion is done by an inverter. A direct connection without this conversion process would not only be inefficient but could also damage the electrical grid or the solar panels. • The Smart Home Panel 2 must be connected to the main house panel, which is part of the grid. Connecting the rooftop solar system directly to the Smart Home Panel 2 could lead to unstable power supply. This instability might result in insufficient power delivery to appliances connected to the panel, causing them to malfunction. Moreover, local regulations stipulate that integrating the rooftop solar system in this manner would necessitate a shift to the current Net Energy Metering (NEM) policy, requiring users to reapply for permits. This process could take several months for approval. Additionally, the new NEM 3.0 policy offers less favorable credit terms compared to the NEM 2.0. Therefore, both from a power usage and economic standpoint, it is not advisable to wire a rooftop solar system directly to Smart Home Panel 2.

What if my house panel is already connected to a rooftop solar system?

If your house panel is already connected to a rooftop solar system (AC Coupling) through an inverter that links to a dedicated breaker, it is compatible with our Smart Home Panel 2. Please be aware that in the event the grid fails, the AC coupling system will also cease to function because it relies on detecting the electrical signal from the grid. When the grid is operational, the solar system can supply power to the Delta Pro Ultra, treating it as a load.

Which EcoFlow products are compatible with Smart Home Panel 2?

The EcoFlow Smart Home Panel 2 is compatible with the Delta Pro Ultra and Delta Pro models. By connecting the Delta Pro Ultra, you can ac hi eve a power capacity of 90kWh and an output of 21.6kW, with a maximum charging speed of 7200W. When connecting Delta Pros to the panel, it's important to note that with only one Delta Pro connected, it can only be charged through the panel. To enable both charge and discharge functionalities, you need two Delta Pros connected via a specialized double voltage hub, which allows for a 7200W output. Each Delta Pro has a power capacity of 3600Wh, and you can expand this capacity by linking up additional batteries, allowing for a maximum power capacity of 25kWh.
