Keith Posted June 6 Report Share Posted June 6 Hi all, Hoping someone can clear this up for me. I came across the Livoltek Hyper-5000 inverter in PVSOL. However, I noticed the PV panels where easily exceeding the Current of the inverter. I notice that the Input current & Short circuit current values (in the 'Electrical data- DC' section) are the same as the values on the MPP inputs ('MPP Tracker' section). However, should it not be the case that for the current values in the 'Electrical data - DC' section, the MPP current values are multiplied by the number of MPP trackers (in this case 2, as there are 2 inputs on this inverter). Thus, this would make the Input current & Short circuit current values in the 'Electrical data - DC' section higher values, therefore the inverter can take higher levels of current. I have attached screen shots which may help. Regards, K Quote Link to comment Share on other sites More sharing options...
developer_mh Posted June 17 Report Share Posted June 17 Hi Keith, you are right, the max input current at inverter level should be the sum of the max input current values per MPP tracker. In the datasheet of the Hybrid-5000 it is stated that the 14 A are the max PV current. In total or per tracker? We don't know. It would be best if you contact the manufacturer and ask. When we divide the 5000 W by 360 V, we get a "nominal current" at inverter level of 13.9 A. So I personally doubt that the max current at inverter level is 14 A. I guess it is 28 A, whereas it is 14 A at MPP tracker level. I will forward this to our database team as well so that they can have a look.
