Wiring Up Batteries and Solar Modules

We are going to describe and illustrate the process of connecting batteries in series or parallel and combination of both. Installation of the solar system and batteries require wiring up configurations in the form of series, parallel and combination of both.

These wiring up configurations can be learned easily. Once learned with interest, then this task becomes easy and simple like a pie.

Two Terminal Points

All devices that generate direct current have negative and positive terminal points. Current or electrons flow from the negative terminal to a positive terminal. This flow is possible through the load. Just for the purpose of an easy explanation, we would represent it to a battery device or solar module device.

Series Wiring

In a series wiring, we connect the positive terminal of one device to the negative terminal of another device. It is key to remember that voltage remains additive when we wire devices in a series. If we say, our devices are capable of producing 12 volts each. Then four devices will produce 48 volts. Suppose that these devices are batteries then their total battery pack is 48 volts. However, if they were solar modules and each produce 17 volts. Then they will produce a total voltage of 68 volts.

Rule Of A Thumb

Another rule of thumb about series circuits is the similarity of current or amperage in a series circuit. Now suppose that batteries where these devices with a rating of 12 volts @ 220 amperage hours. Then total value of the series becomes 48 volts @ 220 amp hours.

Circuit Value Of Solar Modules

Solar modules with a rating of 17 volts @ 5-amperage hours make total circuit value of 68 volts @ 5-amps. In the example given above, two batteries with 6 volts @ 350 amps wire in series yielding 12 volts @ 350 amp hours.

Behavior Of Current And Voltage

Suppose devices were solar modules with a rating of 17 volts @4.4 amps. Then this series of circuits would yield 34 volts @ 4.4 amps. Keep in mind that in the series of circuit current stays the same while voltage is additive.

Parallel Circuits

In parallel circuits, connect the positive terminal of the first device to the positive terminal of the subsequent device, negative terminal of the first device to the negative terminal of the subsequent device.

Key To Remember

Key: In parallel circuits current and voltage behave just opposite to the series circuits. Voltage stay the same while the Current is additive. Suppose each device discussed in this example is capable of producing 350 amp hours while both can produce 700 amps at a same voltage.

Voltage Of Battery Devices

Let us say that these devices were batteries then total voltage of 12 volts @ 700 amp hours will yield. Solar modules will produce 17 volts @ 4.4 amps and each will result in 17 volts @ 8.8 amps.

Solar Modules Wired In Parallel Series

Four 17 Volt @ 4.4 Amp solar modules wired in parallel series yields 16.6 amps total @ 17 volts. Now suppose these devices were batteries with a rating of 12 volts each @ 220 Amps hours. Then this parallel circuit result in 12 volts @ 880 Amp hours.

Series/Parallel Circuits

Hold of your nerves because something wild is going to happen. We have learned almost everything about the series and parallel circuits. Now it is a time to understand a combination of the series and the parallel circuits.

Combination Of Series And Parallel Circuits

It is simply a combination of both the series and the parallel circuits. They wired together in the parallel setting. Suppose two separate pairs of batteries with 6 volts wired together in series and parallel ways.

Raising Amp Hour Rating Of A Battery

Suppose you desire to raise the Amp hour rating of a battery pack. You want to run your appliances longer. You demand to wire the battery pack in such a method as to retain the battery pack at 12 volts. You desire to raise the charging capacity of your solar panels.However, you demand to wire the solar modules in such a method as to retain the solar array at 34 volts. Well, series & parallel are the merely method to do that.

Increasing Charging Current

In fact, you increase your charging current when you wire the solar modules or batteries in parallel circuits because current is additive. Hence increasing run time or amp capacity would increase charging current. For solar modules, we need batteries with a voltage of 17 or 34 volts. When we wire solar module system, we get 12 or 34 volt requirement.

Voltage Produced By Batteries

Wire the batteries in individual sets that will give you the voltage that you need. Let us say that you demand 24 volts but have six-volt batteries on hand. Now wire four batteries of 6 volts in a series to yield 24 volts.

Wiring A Single Set Of Batteries

Wire all four batteries parallel to each other until wired jointly in parallel circuits. Every single set of batteries equals 24 Volts at 350 Amp hours. Subsequently five sequence sets wired to every single set in parallel series yielding a battery pack Of 24 Volt @ 1750 Amp hour.

Assistance In Wiring Up Batteries

Always keep in mind that voltage is additive and current stays same in series circuits while current is additive and the voltage remains same for parallel circuit.
