Adding Your Solar System With Batteries
In 2023, the home solar market grew 40% over the previous year, marking its 17th straight record year. It comes as no surprise given that the cost of home solar panel systems has decreased by roughly 70% over the past ten years and that consumers are increasingly seeking ways to lessen their influence on the environment and save money on energy in the long run. What you should know if you’re thinking about adding batteries to your solar system is covered below.
Why Would a Solar System Need Batteries?
There are a variety of reasons to add batteries to your solar power system, but it’s crucial to first assess whether doing so makes sense in your particular circumstance. The most frequent explanations we have observed for why people ultimately choose to add batteries to their solar systems are listed below:
Energy security: Such as a solar system connect the solar battery to enable you to store solar energy for application whenever it runs best for you, from making your cabin completely off-grid to giving yourself more freedom when on your next road trip. Batteries provide you access to renewable energy at night or on particularly cloudy days, whereas solar energy is typically only used during the day when the sun is shining.
Reduction or elimination of utility bills: If your house is connected to the grid, a solar-plus-battery system can help you save a lot of money by reducing your dependency on your neighborhood utility company. Therefore, you can reduce your utility costs by using solar energy during the day, your energy storage system at night, and utility electricity only when necessary.
Grid buyback Your utility
Grid buyback Your utility can be compelled to buy back any energy you produce more than what you use, depending on where you live. You can store extra energy in your batteries and sell it to your utility by including batteries in your solar energy system. You will receive compensation in the form of a reduced monthly utility cost in situations like this.
Peak price reductions in costs: For the use of power, many utilities have various rates for different hours of the day. For instance, prices are frequently higher during busy times, such as the evening when many people return from work.
Currently, some users are becoming more aware of this, so they will prepare for the next blackout by buying portable solar-plus-storage systems, or adding batteries to their home solar system and calling an expert to set up a solar system.
Environmentally friendly energy source: As the threat of climate change increases, more people are investing in solar batteries to get the most out of their solar system and have access to clean energy around-the-clock.
What To Pay Attention Before Choosing A Solar Battery
When you first start looking at batteries, it might be overwhelming because there are so many different types available, each with different features like power output or cycle life. The following are the most crucial elements you must make sure you examine while evaluating solar batteries:
Whatever a battery agent says to you, you will always read the guarantee period because it will tell you how many years your battery will live based on the overall cycle life or lifespan specified in the guarantee period. For instance, lithium batteries can have a warranty that lasts up to 10 years, whereas lead-acid batteries typically have a shorter warranty period.
The quantity of energy or power that can be continuously held in a specific battery is known as its storage capacity. Generally, Watt hours (Wh) and kilowatt hours (kWh) are units used to indicate capacity. A battery’s capacity can also be expressed in amp-hours (Ah), which are calculated by multiplying the current’s value by its duration. The following are the conversion formulas from Ah to Wh and vice versa:
Wh = xAh volts
Ah = Wh / V
Power is measured in watts (W) and kilowatts (kW)
Power is measured in watts (W) and kilowatts (kW) and represents the rate at which energy is transported. Make sure you know the battery’s rated power before choosing a solar battery.
Power is essential because, even if you merely choose a battery with a bigger capacity, if it has a low power rating, you might not be able to offer enough power for numerous higher-power devices, such as a hair dryer or a space heater.
The roundtrip efficiency of a battery is the ratio of the energy input to the output of the battery. No battery has a perfect efficiency level. Lead-acid batteries often have a lower roundtrip efficiency than lithium batteries. This is crucial since it has an immediate effect on how much capacity is usable as opposed to a nameplate.
Lifespan:
Every battery has a finite amount of time before it starts to lose its capacity to store a charge. Knowing how long your battery will perform is essential if you need to get the most out of your investment in energy storage use. Although lead-acid batteries may be less expensive initially, they need to be replaced considerably more frequently, which results in higher replacement costs.
Voltage:
To make sure the batteries you want to buy are compatible with your solar panels and solar system, you need to verify the voltage of the batteries before buying. 12 volts is the most typical voltage for solar panels used in tiny homes, RVs, camper trailers, vans, and small cabins. You could need a 24-volt system if your energy requirements are moderate. Off-grid homes with more space typically use 48 volts.
Depth of Discharge (DoD):
This term describes how much a battery can be discharged throughout a battery cycle. While lithium batteries like Maxworld Power’s may be depleted up to 100%, many lead-acid batteries will suffer damage if they are discharged more than 50%.
Batteries come in a variety of chemistries, including flooded (FLA), gel, AGM lead-acid, lithium cobalt, and non-lithium cobalt batteries. All Maxworld Power lithium batteries use lithium iron phosphate, also known as LiFePO4, which is the safest and greenest lithium battery chemistry. Lithium batteries can also be installed both inside and outside, whereas FLA batteries can only be installed outside due to the need to exhaust dangerous gasses.
Cost:
Although lead-acid batteries frequently cost less upfront, you will have to replace them considerably more frequently than lithium batteries, which frequently last ten years or longer. Make careful to account for the overall cost of your long-term energy storage investment(s).
Size of Solar Batteries
Your energy needs and use will have a big impact on the size of your solar battery installation. Make a list of the things you will need to use, such as appliances, before sizing your battery. Next, figure out how frequently you use each appliance or other device and how much energy they consume daily. For instance, if you use 2,000 watts for 7 hours each day, your energy consumption is 14 kWh. You should be able to calculate the size of the battery bank you require using this data, the battery’s peak current requirements, the battery bank voltage you’ve chosen, and other factors. To make sure you are never left without access to energy, it is always preferable to over-prepare when it comes to sizing your battery system.
How to Make Maxworld Power Lithium Batteries Perform at Their Peak
It is not sufficient to select the best gauntlet lithium battery for the intended use. Furthermore, you must take good care of it. Here are some suggestions to help you get the most life out of your deep-cycle battery if you purchase a 12V lithium battery.
Discharge Batteries Only to Recommended DoD Levels
Each battery is rated by the DoD. You run the danger of reducing its capacity or altogether ruining it if you push it past that point. To ensure you deplete the battery to the required percentage, keep an eye on its levels and stop the discharge at the proper time. You may even set up a system of controls to do it automatically.
Choose the Correct Charger
Each deep-cycle battery has the ideal levels of voltage and current to ensure efficient charging. When purchasing a 12V lithium battery, make sure to follow the manufacturer’s instructions and get a charger that will properly set the battery’s characteristics.
Charge your batteries
Batteries should be at an 80% charge when kept in storage for extended periods. This makes sure they don’t get discharged after using up their maximum DoD. Additionally, you need to regularly check the charge levels if you aren’t utilizing them. Three to six months apart is more than enough.
Set Them Up Correctly
It is impossible to overstate how crucial correct installation is. Above all, never short-circuit a battery. The majority of manufacturers advise only wiring batteries with the same chemistry and model that you bought at the same time when building a battery bank. This guarantees that all batteries have the same features, including the same cycle life.
