What is a powerwall battery
A powerwall is a rechargeable battery system that power home appliances back up power outages with stored solar energy. Powerwall batteries are self-powered and are designed to automatically detect power blackouts and keep necessary amenities functional with the stored solar energy. This battery is versatile and very customizable to the energy needs of a home.
Why opt for powerwall battery
●Uninterrupted power back up – A powerwall prioritizes charging for backup when the grid is off. The system is designed to spontaneously detect power shortages and hold up till the power is back.
●Monitoring – A powerwall battery contains a feature that monitors the energy consumption of the household. This way you can know how much energy is required to keep the whole house backed up. Also see power percentage, solar panels and appliances etc.
●Time-based- A powerwall that is connected without solar can charge from the grid. It can also be set to a backup only or time-based control setting to maintain your energy needs when the grid is off.
●Self-powered home – The powerwall battery will give you control over your household energy usage and realize independence, security and green life style. Solar energy is also clean energy that should not go to waste.
●Cost-saving- lowers the utility costs and maximizes the savings by charging on off-peak periods and using stored energy. This is a great added feature for backup power of the home and also cuts costs in a commercial setup while still reducing losses that would be incurred in an event of power shortage.
What batteries does the powerwall use
Powerwall battery consist of a rechargeable lithium-ion battery pack in a fully integrated AC battery system. This means that the battery requires an AC to DC inverter incorporated within its system. This makes a powerwall best suited for light commercial use and residential purposes.
Advantages of powerwall battery
●They can be added to an already installed solar panel.
●Powerwall battery can be used for backup-only purposes.
Is powerwall an LFP
Most powerwall battery are iron-based. Their cathodes are made of Lithium Iron Phosphate which is a safer material.
Advantages of LFP
●Environmental friendly material.
●LFP does not decompose when exposed to higher temperatures.
●Do not require any maintenance as they have no memory effect.
●Has the best chemical and thermal stability.
● Has a higher life span of at least 6000 cycles without a decrease in performance
●Can run in extreme conditions without losing its capacity.
●Efficient charge and discharge cycles.
What is inside a powerwall
Inside a powerwall is Lithium iron-based battery pack, protection board and connection points.
●LiFeP04 square aluminum battery pack
●The inverter converts the current from direct to alternating current for use at home
●The connection point connects the home to the solar system through the powerwall.
The most commonly used battery pack consists of 3.2v square aluminum shell battery whose capacity storage is 4.8/7.2/9.6 kwh of energy.
Choosing a square aluminum shell battery
When choosing a square aluminum shell battery you should consider the continuous discharge rate of the cell (CDR). This is the rate at which current can be drawn from a battery without causing it to overheat.
How long do powerwall battery last
On average one powerwall battery can last 12-15 hours at a maximum draw of 2kw. However, how long the batteries can take you is dependent on your usage and whether you are replenishing the stored energy from your solar panels.
The period will vary when the home is completely off-grid and when the powerwall is used partially to sustain the functioning of necessary appliances. A powerwall battery system like Tesla has a 13.5 kW and could last you at least 3-5 days.
The life of a battery
The cycle life of a powerwall battery are a major determinant of the batteries’ life span. These are several causes of battery degradation:
●Overcharge. Continued charging of an already charged battery causes degradation of the battery. Overcharging powerwall battery is a potential hazard that causes damage to the battery. It takes about 7-8 hours for a powerwall battery to be fully charged. Check the battery indicator to plug it out or the charge once it is full.
●Over-discharge- If the power is used up and not charged in time, it will affect the battery’s performance.
●Exposure to high temperatures for prolonged periods reduces the life of a powerwall battery
How many powerwalls would a home need
Generally, a powerwall will be installed as a backup for crucial parts of the home i.e. lights, outlets, and emergency circuits. In an instance where a homeowner desired to power larger appliances, 51.2V 200AH (10KW) powerwall (marked blue) will meet the energy requirements at ease.
How to use a powerwall
A powerwall battery system is a reliable source of electricity for the home. When the battery system is connected without solar it charges from the grid but when connected with solar it also charges from the sun. A powerwall can be fully charged by one solar panel.
Powerwall battery with solar charges by sun and stores energy for when the home needs it the most for example night and blackouts. Those installed without solar charges your utility band is mainly the main source of power to back up the whole home. Back up is dependent on Appliances, home energy consumption, and the number of powerwalls available.
Provisions of a powerwall battery system
●Full Home Back Up
This covers the energy needs for the whole house inclusive of the appliances. This again is also determined by the number of powerwalls you have.
●Limited Home Back Up
This offers backup for only essentials. This way it is operating and can be monitored when the grid is functional. The essentials will be working even on occasions when the grid is down.
General guidelines on the use of powerwall battery
When purchasing a powerwall battery make sure to check your large appliances for their compatibility with the powerwall. If your appliances are not compatible with the powerwall it is safer to opt for the powerwall with high spec for the whole home.
Alternatively make sure to:
●Turn off your large appliances when there is a power outage
●Upgrade to more energy-efficient appliances.
Install the powerwall in the non-living areas of your home like garages or basements. Exposure to high and low temperatures may cause degradation of the battery. This way you can take advantage of its efficiency.
Integration of powerwalls battery systems
These batteries can be integrated with other sources of energy to improve performance.
●Solar- Most commonly used integration where the batteries are installed along with solar panels to act as their source of power
●Grid- Powerwall battery are powered by the grid.
●Generators- a backup generator is connected with a manual transfer switch. This way the generator is only turned on when the powerwall has exceeded maximum output or when its charge is running low. The generator in this case does not act as the source of energy for the powerwall as it is not directly integrated into it.
●Electric vehicles- the home electric panel enables charging of an electric vehicle with solar energy.
Can a powerwall run an air conditioner
A single powerwall may not have the ability to run an air conditioner However, a permanently connected powerwall to a solar system will support an air conditioner comfortably.
Does powerwall work without internet
A powerwall battery system needs to be connected to a cellular network or Wi-Fi. This will enable:
●Monitoring apps use.
●Accessibility of new features over time
Can you go off-grid with powerwall
