Description Datasheet

SunFusion Echo 2.0 3T > 15kW Inverter/Battery Cabinet with 28kWh

Sunfusion Echo 2.0 3T for Indoor or Outdoor - Partial Home Backup

The ECHO 3T 28kWh/15kW is a true partial home backup system. SunFusion did not want to follow the competitors, so they gave the homeowners what they needed for a real arbitrage and TOU usage. The average Time of Use period (TOU) is from 4pm -9pm. Most homes use 10 to 25kWh in a single night. This is why the utility changed the time period when there is no sun. The best savings is by charging from the sun, as long as you have adequate solar PV installed.
