Can DC and AC cables run in the same conduit?

By |2020-06-29T11:58:08+05:30June 29th, 2020|

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 [...]

Inspection using thermal camera

By |2020-06-18T22:49:13+05:30June 15th, 2020|

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 [...]

How panel level monitoring has helped…

By |2020-06-18T12:42:51+05:30June 14th, 2020|

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 [...]

Charging lead acids properly

By |2020-06-09T20:33:30+05:30June 9th, 2020|

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 – Types, Working and Trip Curves

By |2020-06-09T13:55:40+05:30June 9th, 2020|

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 [...]

Optimum tilt angle for fixed panels

By |2020-06-08T10:58:03+05:30June 8th, 2020|

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 [...]

Solar Window Period

By |2020-06-08T10:39:48+05:30June 8th, 2020|

Overview Almost in all meetings, we have noticed that clients require clarification on the placement and orientation of panels. Particularly, clients have pointed out that shadows are falling on panels at 5PM or early morning at 7AM. In this regard, it is imperative upon the EPC to educate the client on the solar window [...]

Understanding C-rate

By |2022-08-16T08:25:27+05:30May 13th, 2020|

Let’s get the basics right for C rate.If someone says to you that they are supplying a 100Ah battery, then it has no meaning. It is incomplete information. It is like a shopkeeper saying to you, “I will give you 2 Oil”. Whether it is 2 liters of Oil or 2 bottles of Oil has [...]

Criteria for sizing battery banks

By |2020-06-02T22:27:01+05:30April 22nd, 2020|

Solar Battery: Design it right. In solar applications, a lengthy charge time is not desirable since we only have a maximum of 4-6 hours of peak sun each day due to limited daylight and varying weather conditions. To ensure that the batteries receive enough charge, batteries must be adequately sized to prevent deficit charging [...]
