Series Connection of Batteries with Solar Panel
We can do the wiring connection of batteries in the series, parallel or both combine series and parallel as per our requirements. Here, the wiring connection of  24V solar panel with the series connection of two 12V batteries is given. The voltage of solar panel is 24V so we have to required the two number of 12V batteries. 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).

Parallel Connection of Batteries with Solar Panel

Here, the wiring connection of  12V solar panel with the parallel connection of two 12V batteries is given. 

Mostly solar panel have rating like 12,24,36 volts. Here,we are using 12V solar panel and parallel connection of batteries. The batteries are in parallel so we required two 12V batteries. Aiding more batteries in parallel gives you more capacity. i.e., If you have one 120Ah battery that able to make run a fan for 24 hours then adding one more battery in parallel gives you 48 working hours for same fan.

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...

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 cu...

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 ...
