We are asked often why a customer cannot see the power flows from the inverter on the device screen when the inverter is a Hybrid/DC-Coupled system.
What is a Hybrid Battery?
Battery systems that charge directly from the solar array and cannot charge from AC are usually referred to as being DC-Coupled or Hybrid.
This type of battery system uses the solar PV inverter to provide power from the batteries, thus it is not possible to differentiate between solar and battery power when using a CT to measure the AC current
from the inverter.
Due to this, we cannot distinguish on the myaccount or graphs what is excess solar or battery power. As long as you have an export back to the grid of the 1.4kW required to start a charge while that is ongoing Zappi will charge the vehicle.
