I-V 400 is the ideal solution for the ordinary and scheduled maintenance of photovoltaic systems. With I-V 400, searching for possible failures and problems in systems is extremely rapid, efficient and intuitive. I-V 400 carries out the field measurement of the I-V characteristic and of the main characteristic parameters both of a single module and of module strings. The instrument measures, together with the I-V characteristic of the device being tested, also the values of its temperature and incident irradiation.
The acquired data are then processed to extrapolate the I-V characteristic at standard test conditions (STC) in order to proceed with the comparison with the nominal data declared by the modules' manufacturer, thus immediately determining whether or not the string or the module being tested respects the characteristics declared by the manufacturer. Output current or voltage from the module or string is measured with the 4-terminal method, which allows extending the measurement cables without requiring any compensation for their resistance, thus always providing accurate and precise measures.
In its internal memory, I-V 400 manages a database of photovoltaic modules, which can be updated at any time both via the management software and directly on the instrument. Together with the measurement of the I-V characteristic and the extrapolation of the characteristic at standard test conditions, I-V 400 compares the obtained values with the values declared by the manufacturer, immediately providing the OK / NO result of the test. The operator must not do any calculation, nor any difficult operation. The instrument carries out the comparison rapidly and automatically

Like it. just installed a 10 kilowatt array in Huntsville Ontario. Canada.
Well shot and easy to understand.
Good job on the video!
Please help me , In my result in all PV module I am getting negative dp
@@hafizsalmanishrat7940 , obtuviste alguna solucion?
Very easy to use, I tested hundreds of panels a day :)
is there a new updated version of this unit?
I'd be VERY CAREFUL connecting to the entire string, It has a high voltage and high current and can give you a bad burn. DC can really arc and make a nasty burn on you and the connectors!
The DP max, as long as it is +, all panels are okay right? How about if the reading shows 0.95 ? Still normal?
I want ask you something,why I test the HT,the erro is a unstable currently
Please help me I test almost 100 module but in all test I am getting negative dp, Is any more setting I need to make
How do I reset the device to factory settings?
Plz tell me about testing kit
Why is this guy ramming MC4 connectors into MC3 connectors? Lol 😂
what negative value is he talking about?.....DPmax?
40MW Amherstburg ON
Im work
I made it with Avasva solutions.
do it yourself , go to inplix page and learn how
