Smart Home Panel

Smart Home Panel with Two Delta Pros

I have 2 Delta Pro (DP), each with two extra batteries for a total of 21.6kWh. This feeds into the Ecoflow Smart Home Panel (SHP). The SHP is wired to a sub panel, which has various circuits throughout my house: kitchen, office, bedroom, bedroom mini split, etc.

I charge the DPs 2 ways. I have a solar tracker that gives me around 1.3kwh via the Anderson Port. When my rooftop solar is generating more power than I am using, it turns on the AC coupled charging via the SHP. They can both charge at the same time.

Charging the Batteries and Time of Use (TOU)

Since my solar panels on my rooftop are micro inverters and grid tied, when I am producing more power than I am using I like to charge my Delta Pros via the AC coupled smart home panel.

This is what the Ecoflow mobile app looks like when setting a charge time for the Delta Pro Batteries. Port1 and Port2 are the Delta Pros. Recharge rate is per Delta pro and is from 200 watts all the way to to 3400 watts each.

I always try to get my batteries charged to 100% before the 4pm hour because that is when my Kwh charge goes from $0.31 to $0.52. Most of the time I have enough solar power to get the batteries to 100%.

Also, my Smart Home Panel flips over to backup mode at 4pm, so most of my house runs off the batteries from 4pm to 9am the next morning. This on average consumes around 1/2 of my batteries power, around 11 Kwh.

Instead of using the Ecoflow app and manually adjusting the recharge rate of my Deltas Pros, I use the Ecoflow API with a combination of Home Assistant to trigger the recharge. This can be done because my rooftop solar is Enphase and the Enphase Envoy talks directly to Home Assistant and give me Energy Consumption and Production with update speed of around 10 seconds. Before this integration I would just have a timed charge rate similar to the app picture with a low charge rate, as not to draw power from the grid.
