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 [...]
Solar Installation at Rainbow Drive Villa Community, Bangalore | India Solar Plant Generation in Bangalore, India Generation during Monsoon Season? “Does it work at all in the monsoon months?” “I don’t think Bangalore is an ideal place for Solar Rooftop [...]
A lot of time, effort and money can be save if one has the right tool in hand. One such useful device is the thermal imaging camera which EcoSoch has invested in. It is important that electrical components work correctly and in case of any fault, it should be detected as early as possible [...]
We will have a look at a couple of our sites where we have installed solar panels with SolarEdge systems and how module level monitoring of panels has helped us in identifying issues. Case Study I - Solar Panels @ Krishi Group, Bangalore We noticed that 2 of the solar panels were producing less [...]
The life of a solar plant can be 25 years or more but how do we ensure it? We have seen many installations where usage of substandard materials has been quite prevalent. Though they may serve the purpose for the first few years, they will never last 25 years for which solar systems are [...]
Charging of lead acid batteries is not an oft-spoken or documented topic. So here I would like to describe how to charge lead acids properly using the 3-stage method (Bulk, Absorption and Float) or the CC-CV method as shown below. Particularly, the “Charging current during Bulk phase” and the “Time for Absorption phase” that [...]
MCB or Miniature Circuit Breaker is an electromechanical device which protects an electric circuit from an overcurrent. The overcurrent in an electrical circuit may result from short circuit, overload or faulty design. In short, MCB is a device for overload and short circuit protection. They are used in residential & commercial areas. Just like we spend the time to make [...]
Solar panels generate the maximum output when the sun-light falls perpendicular on the panels. However to achieve the ideal harvest of solar energy, you need to have a multi-axis tracker which throughout the day and throughout the year face the sun and try to maximize the generation. The only disadvantage with such a system [...]
