Comparison Growatt MIN 2500TL-X vs Growatt MIN 2500TL-XH

The maximum allowable input power from solar panels, expressed in kilowatts (kW). Let us remember that 1 kW contains 1000 W.

When selecting an inverter based on this indicator, they are based on the total power of the solar panels involved in generating electricity. Moreover, it often makes sense to select models with an inverter input power slightly less than the maximum power of solar panels - for example, if they are shaded part of the time or for other reasons do not receive enough sunlight during the day. The power of the solar battery should not exceed the power of the inverter by more than 30%. However, for some inverters the excess can be only 10%, while for others it can be up to 100%. It is better to clarify this point in advance.

The operating range of the inverter is usually located between the starting voltage and the maximum voltage. This interval is indicated in volts.

The noise level in decibels (dB) produced by the inverter during operation. The lower this indicator, the more comfortable the use of the equipment will be, which is especially important for residential premises.

Note that decibels are a non-linear quantity, so the easiest way to assess the noise level is to use comparative tables. Here is a simplified table for the range that most modern inverters fall into:

35 dB – conversation in muted tones;
40 dB – quiet conversation; maximum noise level allowed in residential premises during the daytime;
45 – 50 dB – conversation in a normal tone;
55 dB - background noise in an office without special noise sources;
60 dB - loud conversation;
65 dB - city street with average traffic intensity;
70 dB - a conversation between several people in a raised voice.
