REFUsol AE 3LT 13K Grid-Tied Inverter

Description

Choosing a grid-tied inverter for a solar power plant is an important decision, as the overall performance of the solar power plant depends on the inverter’s performance and quality. A German manufacturer of power equipment has produced a high-quality inverter, the AE 3LT 13K model. It is designed to operate in a grid with a total capacity of 13 kW.

The AE 3LT 13K three-phase grid-tied inverter operates with a maximum input power of 15,600 W. As part of a solar power plant, it converts the direct current (DC) generated by solar panels into alternating current (AC) to power the home’s electrical system.

 The MPPT tracker's voltage range on the DC circuit is from 480 to 800 V. The device's start-up voltage is 350 V. The maximum input voltage is 1,000 V. The maximum input current is 31.1 A. The device’s architecture calls for the use of a single MPPT tracker with four inputs. The maximum output voltage is 13,000 V. The voltage range on the AC circuit is from 320 to 460 V. The device’s efficiency of 98.1% allows it to operate effectively over the long term (with proper operation, the device will last more than 20 years). The warranty for this inverter model is 60 months. The device’s standby power consumption in night mode is 0.5 W.

The device has undergone a series of certifications. The declared protection rating meets the IP65 standard. This ensures the device is protected against external factors such as dust and moisture (water jets from any direction). The temperature range to consider when installing the device outdoors is from -25 to +55 degrees. It complies with the 4K4H environmental standard.

The device uses passive cooling—natural convection. It is important to prevent direct sunlight from hitting the device to avoid overheating. To do this, place it indoors and ensure natural ventilation. Alternatively, place it outdoors but install an additional canopy over the inverter.

Ethernet and RS485 communication interfaces allow information to be transmitted to the user’s external devices (such as a personal computer) or to monitor operation directly from the display located on the device’s housing. The device has a built-in temperature sensor and a sunlight sensor.
