At EcoSoch, we use UPVC conduits on the rooftop for a reason whether it be residential, apartment, commercial, industrial or institutional projects as shown below: However, the current norm of other EPC vendors is to use perforated Pre-GI cable trays to carry the DC cables for large projects as shown [...]
DC Voltage Drop For Solar PV installations, the standard to follow would be from Australia called AS/NZS 5033:2014. It states, "For LV PV arrays under maximum load conditions (Imp), the voltage drop from the most remote module in the array to the input of the inverter should not exceed 3% of the Vmp voltage [...]
Please have a read of the below article from Nuevosol which talks about corrosion in Pre-GI and Hot Dip Galvanised (HDG) Structures. Salient points are as below: Nuevosol article Pre-GI can be used as long as it is 550 GSM steel. The galvanization coating thickness is a maximum of 20 micron each side for [...]
Basics A CAT6 cable can theoretically carry data for 100m but after 80m, there would be signal attenuation and it would be impractical. So 80m is the practical limit for CAT6 cables. An RS485 cable can carry data upto 4000ft (or 1.2km) @ 100kbps as shown below. If you need more information on the [...]
We have been asked a few times in the recent past as to whether we can run DC and AC cables run in the same conduit.The answer is No since the DC cables could induce a DC voltage onto the AC side. The AC sine wave should oscillate about the 0 volt axis i.e., the positive and negative [...]
Not the usual day it was. Very lovely weather. Mesmerizing for people working in Sun. We started to our site having hot tasty breakfast of our choice. We started with an enthusiasm that we will finish installation of 1000 panels crossing 300 kW on the project we are working. Started at our usual time 8:45 [...]
