Product Description:

EA4KDL/EA4K6DL/EA5KDL/EA6KDL    

EA4KDL / EA5KDL / EA6KDL is designed for residential and small commercial PV installations. This inverter has dual input section to process two strings with independent MPPT, high speed and precise MPPT algorithm for real-time power tracking and energy harvesting, as well as transformerless operation for high performance efficiencies of up to 97.5%. The wide input voltage range makes the inverter suitable to low power installations with reduced string size. This outdoor inverter has been designed as a completely sealed unit to withstand the harshest environmental conditions.

   

● Transformerless, maximum efficiency up to 97.5%
● Dual input sections with independent MPP tracking, allows optimal energy harvesting from two sub-arrays oriented in different directions
● Wide MPPT range, convenient for module configuration
● High speed and precise MPPT algorithm for real time power tracking and improved energy harvesting
● High reliability with full protective functions
● Ideal for outdoor installations
● Water-proof direct plug-in terminals
● Multilingual LCD, easy to operate
● Integrated multi-communication interfaces, easy to monitor
● TÜV, AS4777, CE, CQC certification

·         Q. What's lifetime of a UPS ?

Most plug-in UPS are workable for at least five years. We'd advise you to change the batteries every three to four years. For larger equipment, we maintain equipment for twenty years old and still going strong.

·         Q. How to maintain a UPS ?

There are three simple methods:  Never overload your UPS, never connect any home electronic devices such as cooling fan to your UPS. This may cause malfunction of your UPS. Discharge the battery in a consistent interval, once a month or once two months.  You can do this by turning on the UPS without connecting the mains.
