Battery Storage Solution

Power Everyday With Renewable Energy That You Can Use Day And Night.

Solar Battery Storage

Solar panels require sunlight to create energy, so as soon as its dark you'll be back using power from the grid. Having a battery means the surplus solar energy can be fed into the battery. The batteries are charged during the day by means of solar energy. The surplus solar energy is fed into the battery rather than being exported to the National Grid. This means that the batteries are always fully charged so that these can be put to use at night-time.

For the last 14 years we have specialised in the design, installation and commissioning of Renewable Energy systems, LED lighting system design and installation, Electrical Inspection & Testing, Battery Storage and EV charge points, De-stratification systems and all Electrical contracting from domestic to Industrial including repair and maintenance in Dorset, Hampshire and surrounding counties.

In the summer, when there is adequate solar energy, the home can run up to 3 weeks at a time without relying on the national grid. The StorEdge solution helps home owners reduce their electricity bills while maximising energy independence from the grid. StorEdge is compatible with Tesla’s Powerwall Home Battery, and is based on a single SolarEdge DC optimised inverter that manages and monitors PV production, consumption and storage. Unused PV Power is stored in the battery and utilised when needed to maximise self -consumption.

How Much Capacity Do I Need and What Does It Mean?

The renewables industry is becoming increasingly popular in recent periods amongst people wanting to save on energy bills and run their lifestyle with natural energy that directly impacts the environment. With this, costs of battery storage are becoming more and more affordable making it more viable for customers to invest and have a backup plan in the event that their primary source of power is inaccessible, or a power cut occurs. Some people even take the opportunity of using battery storage as an everyday evening backup after their solar is no longer generating.

The “capacity” of a battery is the amount of kWh energy that is available to be stored within that device. The amount of capacity your storage device has will vary from brand to brand. Some, cheaper storage devices will, as a result, have a lower storage capacity where others such as the Tesla Powerwall's will have considerably higher capacities to give you flexibility with your energy.

When it comes to finding out how much capacity you’ll need for your battery storage it’s the amount of “usable” capacity a battery has that you're looking for rather than the “total” amount its able to store. So that there is no internal damage done a batteries total magnitude will never be fully run down but instead your battery will exhaust only its usable capacity. It's important to know this so you don’t get the wrong information about a product because the storage size Is not as you thought.

Is Battery Storage An Ideal Solution?

When you're unable to carry on generating solar in the evening time it could be incredibly handy having a useful backup plan in order to carry on running your day to day electrics as normal. This is where we suggest investing in your own battery storage device. Any surplus energy your solar system generates that you don’t use will be stored straight into your battery ready for use later on. Making it easy to become self-sufficient and untied to the grid

While using the amount of capacity to power your home correctly it's important you have the right amount of storage to accommodate your needs for ultimate long term reliability.

Are Solar Storage Batteries Worth It?

Solar storage batteries are used to utilise the energy your solar produces in the day with the ability to store it and use it later on. At Empower we know how helpful this is for any homeowner looking for a solution to a frustrating problem with the goal to be self-sufficient all day long, without the need to be so reliant on your solar system.

Can You Power A Home With Battery Storage?

Powering your home on Battery storage is possible however, it involves multiple considerations in different areas to know whether its a smart and viable decision for your household. Different batteries have varied power capacities so if your looking to run your home's electricity on stored solar energy one of the things you'll need to consider is the type of battery storage device your investing in. Batteries that have higher energy capacitiy give you more freedom and opportunities to run your house exactly the way you want to with the ability to store excess energy in the battery device because their maximum energy hold is higher. We offer two very different but equally intelligent battery storage solutions including the Growatt storage solution and the Tesla Powerwall 2. The Tesla Powerwall 2 has a high capacity of 13kWh over twice as much as their first-generation Powerwall. Before rushing into anything researching the different battery storage devices available on the market to get an idea of price ranges, benefits and possible problems that may occur is essential.

How Many Batteries Are Needed To Power A House?

This will depend on your households electricity usage per month and the size of your home. Most homes require no more than one battery storage device to power their home, however, if you're looking to store large amounts of energy for backup supply in case of a power cut or unexpected situations you may need to look into investing into more than 1 battery storage device. Talking to your expert installers will give you a better idea of how much energy you're using if your not sure and the size and amount of storage you'll need to power your home.

How Long Can A Tesla Power A Home For?

Tesla power walls can power a home for days at a time if need be, however, they aren’t designed for this purpose instead they act as a backup if the primary energy source is unavailable or not working. The Powerwall is also designed to substitute the solar array in the event of a power cut or anything similar

How Long Does A Tesla Powerwall Last?

Tesla power walls have a 10-year warranty. However, many customers have used their battery storage device for many years after this with no complications. It all depends on reguarly your household use it as to whether youll get longer than 10 years out of your device. For instance if you only use your battery storage as a backup in case of a power cut or anything similar then your battery may still operate perfectly even after your 10-year warranty has finished, whereas if you’re a homeowner that regularly uses your battery storage on a daily basis then your Powerwall is less likely to last over the 10 year warranty period as a household that uses it less frequently.

How Much Will A Tesla Powerwall Cost?

Battery storage devices can vary in price so it's difficult to put an exact number on what yours will be at least until the required details are given to make these calculations. The price of your Powerwall will be determined on 2 factors; The average electricity usage your family consumes regularly as well as the size of your solar system. Powerwall’s are one of the more expensive battery storage products on the market however, there are plenty of benefits the Powerwall gives that you wouldn’t receive from any of the other battery storage devices on available on the market.

Can I Go Off-Grid With Solar Batteries?

The Tesla Powerwall 2, allows you to go off-grid with your electricity due to the large number of capacity it holds, however, you'll still need to work out the amount of electricity your home uses each month to know if going off-grid with your solar battery is viable.
