FAQs 6

What causes a DC inverter to overvoltage?

This can arise from high inertia loads decelerating too quickly, the motor turns into a generator and increases the inverter’s DC voltage. There are other causes of DC overvoltage, however. POSSIBLE FIXES: Turn the overvoltage controller is on. Check supply voltage for constant or transient high voltage. Increase deceleration time.

Why does my inverter go into 'voltage-dependent power reduction' mode?

Why your inverter goes into 'voltage-dependent power reduction' mode In marginal cases your inverter may not trip off, but may reduce its power output instead as a way to cope with grid voltages that are a little too high. When your inverter reduces its power due to high grid voltages it is in what's called "Volt-watt response mode".

What causes a voltage rise?

Voltage Rise - Typically occurs with the same inverters at the end of a cable run and is caused by resistance greater than 2% voltage drop. Wires have resistance causing Voltage Drop. All grid-tied inverters increase voltage to export power. Typically they only need to raise the voltage above the grid and any wire resistance. Enphase calls

Why is my solar inverter causing a voltage rise?

3. The maximum voltage rise between your solar inverter and the grid is above the 2% maximum in the Australian Standard, because the resistance in the cable (including any connections) is too high. If this is the case then the installer should have advised you that your AC cabling to the grid needed upgrading before solar could be installed.

What are the most common power inverter problems?

Over 60% of inverter failures stem from preventable problems such as loose connections, overloaded circuits, or poor maintenance. This guide takes an in-depth look at the most common power inverter problems faced by users and provides actionable solutions backed by specialized knowledge.

When should a solar inverter disconnect from the grid?

The Australian Standard for Solar Inverters AS4777.1 mandates that an inverter must disconnect from the grid if: So if your inverter trips on an 'over voltage' error, the voltage where the grid connects in to your inverter has breached one or both of these limits.
