What is backflow power?

The backflow power implies the energy transferred from the bus to the battery every switching period if the power is transferred from the battery to the DC bus or vice versa. It is obvious that the larger the backflow power with the same average transferred power is, the larger the effective current becomes, which means larger conduction losses.

What happens if I Turn Off backflow power?

If I turn off backflow power, the battery will get the full recharge rate from the panels. If backflow power is off, the battery gets to 100% and nothing is generated from the panels if the house doesn't need power. If I set the backflow power to the rating of the inverter, 5kw, the battery won't recharge, or will at a lower rate.

Does a load SW have a backflow prevention function?

With a load SW, etc. equipped with backflow prevention function, the voltage on output side may be output to the input side depending on the backflow prevention control system of the product. It is necessary to keep this in mind.

Why is a complete backflow prevention circuit necessary?

This is a fatal problem. For this reason, a complete backflow prevention circuit with low current leakage is necessary. The simplest and most effective measure is configuring a complete backflow prevention circuit using the ideal diode IC.

Is backflow designed to limit export to the grid?

Isn’t Backflow designed to limit export to the Grid by the value set and when the house demand is satisfied and battery full it reduces the inverter output accordingly. Isn’t Backflow designed to limit export to the Grid by the value set and when the house demand is satisfied and battery full it reduces the inverter output accordingly.

Does a charger IC have a backflow prevention function?

However, for charger IC that has no built-in backflow prevention function or devices for which a device with a built-in charger IC and a device equipped with a battery are separated, it is necessary to take measures against voltage output to external terminals.
