6 FAQs about [The mppt current of photovoltaic inverter is too large]

What happens if a PV inverter does not have an MPPT circuit?

An inverter without an MPPT circuit would result in lower efficiency operating outputs between any PV module (or string) and the inverter. Unless the inverter can match the PV strings to extract maximum power the result is a lower power output during operation for the connected strings.

What happens if a PV inverter exceeds MPP current?

Should the MPP current of the PV array exceed the maximum input current (I DC max.) of the inverter in a particular system design, there will not be any potential for damage to the inverter. Exceeding the MPP current therefore also has no impact on the inverter’s statutory warranty.

What is a MPPT inverter & how does it work?

The MPPT circuit constantly monitors the array voltage and current and attempts to drive the operating point of the inverter to the maximum power point of the array, resulting in the highest energy harvest. Bottom line, the MPPT is designed to increase the amount of power you get from your PV array. They are worth having in most circumstances.

What is the maximum input current for a MPPT?

If each MPPT has two strings, the maximum input current for each string is 12.5A. If there is only one string, the string current is less than 25A. Inverter current peak clipping issue: What causes it? Inverter current peak clipping issue may occur when the selected component current exceeds the maximum input current of the inverter.

How many MPPT trackers should a PV inverter have?

If you have one PV string then 1 MPP Tracker is fine. If you have multiple PV strings then its often the best case to have one MPPT for each string. Different inverter companies offer string inverters with upwards of 6 MPPT trackers. Inverters typically have 2 to 4 inputs per MPPT tracker as the idea of balancing cost with efficiency is important.

How to choose a PV inverter?

When it comes to choosing an inverter, the I SC PV short-circuit current (“SC” stands for “short circuit”) is always the deciding factor. This value indicates the highest electrical current that a PV cell or PV module can deliver.
