Solar batteries are quite in vogue now, and people like the fact that this can serve as both a viable fuel backup source for energy in the short term, and an ecologically liberating go to an energy source in the long term. This said, there is more to solar panels and solar batteries—and things that go solar—than just soaking up solar energy and storing it up for later use.
“Really?”, you ask, “there is more to this whole thing than just extra energy storage”? Why, yes, my friend, there is a bit more and while we are it, that “a bit more” could give you some ideas in the future as to your future with regards to solar technology products.
All right, so in this article, we take the good and the bad of solar batteries (batteries that store solar energy) and how to set up these batteries to make a solar battery bank setup (like a power bank, for you know, larger appliances).
All right, let us not waste too much time and get right to some facts: a solar battery bank setup is just a fancy term to indicate multiple solar batteries linked up to produce a compact source of storage. So, yes, there really is not much to say of this matter except that you may not know how to go about such a process and you are maybe confused as to what the fuss is about.
If you are not, then you can now take this advice and share it with other people (this article, too, of course). If you are confused and in need of some info, well, this article might be the answer that clears up your problem. Without further ado, let us get into the solar battery bank setup essentials.
The Kind Of Batteries For A Solar Battery Bank
For batteries of a solar battery bank setup, there are two that always come up in observation:
1. Lead-Acid Type
2. Lithium-Ion Type
The most common (and often, cheaper) amongst these two is the lead-acid type. That said, lithium-ion is then more expensive but for the price of greater efficiency (trust me, friend, this term is really important concerning all things battery) and longer lifespan, not to mention greater energy density than the ones you find in the lead-acid types.
Wait, just a minute, I could just buy a solar battery ba…
No, no, no! You cannot just buy a solar battery bank! Just kidding, of course, you can. Most handiwork and manual labor today is done a lot by other people and there is no shame in having your solar energy system set up by installation packages from stores (really, no shame, at all).
But, it may cost you a pretty penny and some extra money, depending on the service. If you have time and some curiosity, you can set up your own. That said, let us now move along the process, now, friends.
Setting Up A Solar Battery Bank
1. To determine the solar panel energy production that occurs in a span of a day (including those induced by your several appliances).
2. Take notes of how weather and seasons affect your solar panel energy production (winter vs summer, for example).
3. Understand that the conversion system of your household appliances will be under the kilowatt-watt-hour calculation.
4. Understand that the conversion system of your solar bank setup will be under the voltage-ampere-hour calculation. (Learn how to calculate battery capacity).
5. Do remind yourself to add up everything that uses energy on a daily rate. Case in point, if your television, fan and computer wattage is 100, 300 and 400 watts, respectively, then you are looking at a total of 800 watts utilized per day. If your solar battery system has a voltage of 21, you would divide 800 watts by 21 volts and you would get 38.0 amperes-hour. Your bank battery would need 38.0 amps per hour stored in it to match your appliance costs of energy.
Connecting Solar Batteries For A Solar Bank Setup
Essentially, there are about two ways you can go about this. You can do them in either parallel or in series.
The positive (+) terminal of each battery is placed right next to negative (+) of another battery—this is the linkage. Doing it this way provides a combined voltage from the added batteries. If you have batteries that have, say 6 volts each, you can link them up in a series to join them as one voltage of 12-volts.
The negative (+) terminal of each battery is linked together with the negative terminal (+) of the next battery as well as linking the positive (+) terminal of each battery. You can then add all of the amp hours of these batteries together.
Also, you will need an inverter (the device responsible for converting DC or stored energy to AC, of which is useable energy). The more electric grids you plan to connect, the more you need to invest in proper inverters. And, these inverters will mostly likely need to correspond to the wattage of your appliances.
Having A Controller For Solar Battery Bank Setup
Oftentimes, a “charge controller” is given a mention. Rightfully so, this is a type of controller that regulates the charge of your solar system to your given battery set. This is important because without the monitoring that comes from this, the battery you have may be damaged because of states like overcharging.
As with the type of batteries, there are two types of charge regulators or controllers:
1. Maximum Power Point Tracking
2. Pulse Width Modulated
And, as with lead-acid and lithium-ion, maximum power point tracking (maximum, being a hint) has a better track record than the common pulse width modulated type, albeit the former is more expensive despite being energy efficient.
The choice will ultimately be up to you and the manufacturing shops you decide to talk to and gain advice from. Hopefully, this article has given you some perspective on how to go about a typical solar battery bank setup. Till next time!
