Comparison Deye SUN-8K-SG01LP1-EU vs Deye SUN-8K-SG03LP1-EU

The rated output power of the inverter, expressed in watts (W).

This parameter means the power that the device can provide to consumers for an unlimited time. It is necessary to choose according to this indicator so that the rated power of the inverter covers the power consumption of the expected load by approximately 15-20%. It is also worth considering that some electrical appliances (in particular, units with electric motors - vacuum cleaners, refrigerators, etc.) consume significantly more energy when starting up than after entering the mode. For such a load, it is also necessary to clarify the peak power of the inverter (see the corresponding paragraph) - it should be higher than the starting power of the load.

The highest total output power in watts (W) that the inverter can deliver to a load for a relatively short period of time, on the order of 2 to 3 seconds. As a rule, this power is 30 - 50% more than the rated power (see above). The peak load value can be useful when calculating how the inverter works together with appliances that consume a lot of energy at start-up (vacuum cleaners, borehole pumps, power tools, etc.). The rule here is simple - the peak power of the inverter must not be lower than the starting power of the load.

The efficiency of the solar system, laid down by the manufacturer of the inverter, directly depends on this parameter. The following battery voltage options are most widely used: 12 V, 24 V and 48 V.

Ambient temperature range in which the inverter for solar panels is guaranteed to maintain normal performance. Here it is necessary to focus on the expected minimums and maximums of temperatures. Moreover, for operation in the cold season, it is worth paying close attention to models with the ability to work at sub-zero temperatures.
