Series Connection of Solar Panel
Series connection of solar panel with parallel connection of batteries and UPS
The circuit diagram of series connection of solar panel with the parallel connection of batteries and UPS is given above. The two 6V solar panel are connected with two 12V batteries and automatic UPS system. As you know in previous article, parallel connection of batteries gives double capacity with same voltage. The current in the parallel connection of batteries is different while voltage in the parallel circuit is same.

Here, if we connected two 12V and 120Ah batteries in parallel it will gives you 12V 240Ah at the end. That means, one 12V battery work for 120Ah but connecting them into parallel gives 240Ah for same voltage.

Parallel Connection of Solar Panel
Parallel connection of solar panel with series connection of batteries and UPS
Here the two 24V solar panels are connected with two 12V batteries(In series) and UPS syetem. As we know the solar panel produces the 24V and our batteries connected in series so batteries must be 12V each. The batteries in series gives us 24V (12v+12v) DC so, the 24V inverter is requuired for this.

One thing keep in mind is that by connecting the two batteries in series we can not double the capacity of batteries. It is possible by connecting them into the parallel. In the series connection of batteries the current is same and the voltage is double(only voltage is double not the capacity).

In this article we learn about how to control a lamp with 3 different switches at different places. This is very useful. For doing this we required two 2-way switch, 1 intermediate switch and a lamp. Connect all these as shown as in the below diagram. Fig.-1 In the above diagram the lamp is on because the circuit is in closed condition.To understand easily the circuit diagram for this, is given below.  Fig.-2 In this case the lamp(bulb) is in off condition. So, the circuit is open condition. Here, one more example is given.  How you can turn on/off a lamp or bulb from six different places. For this we required four number of intermediate switch, two number of 2 way SPDT switch and 1 bulb. Connect all these components as shown as in the figure below. Fig.-3 What is Intermediate switch , its construction and working principle? Fig.-4 An intermediate switch have four terminals. Because of this terminals it is possible to change the flow of the current fro

In this article you will learn about how to do three phase wiring in home. Generally, the elctrical supply provider company install single phase energy meter for where requirements is 7.5 kW load in domestic areas but if this limit exceeded then they install 3-phase meter. For this we required following things. Requirements- Required Materials Number Three phase energy meter 1 Three pole, 63 A, MCCB 1 Double pole, 63 A, 30 mA, Trip current RCD 3 Double Pole MCBs, 63A 3 Single Pole, 20A, MCB 6 Single Pole, 16A, MCB 3 Single Pole, 10A, MCB 6 Distribution board cases 3 Cupper strips for MCB Common connection 3 Here, the connected load is single phase. their is no 3 phase load connected to the 3 phase system. The 3 phase wiring are used because our load is more then 7.5 kW. Now, let's start the procedure how to install 3 phase wiring for your home. Figure 1- 3 phase winding in home As shown in the

Automatic UPS system wiring for home or office This article is about how to connect a UPS system in our home or office and this is very useful information.  The below circuit diagram shows the how to connect a UPS from our main supply to appliance(load). This circuit diagram is for in case of falling the main power supply and you want to supply power to specific appliances, TV, AC, laptop etc. in your home or office.  As shown as, two rooms are connected with main power supply.  Here, you don't have to connect the neutral wire connection from UPS because it's already connected the phase and neutral wire from the main power supply with the same point. To connect UPS first you have to remove the connection of phase wire from the main distribution box(from SP,DP or CB) of those rooms which you want to connect with UPS. By doing this(connect with both supply), we can use the power without interruption. If main power fails the UPS will provides the power to the
