In the past ten years, lithium-ion technology has developed rapidly, and Tesla has become one of the most innovative and innovative home battery storage technology companies recognized by everyone, but it is precise because of this that Tesla has brought a surge in orders and The long delivery time, so many people will think, is Tesla Powerwall the first choice? Is there a reliable alternative to Tesla Powerwall? Yes.

BSLBATT LiFePo4 Powerwall Battery is one of them!

One fact that continues to surprise people is that Tesla is not the first company to manufacture storage solutions. Energy storage technology has actually existed for decades. Lead-acid batteries have played an important role in keeping people off the grid altogether-but at a high cost.

Why does Tesla have such a big impact on the solar storage market?

In our opinion, most of the hype surrounding Powerwall stems from Tesla's excellent marketing and branding efforts-they are undoubtedly the technical symbol of Apple in the field of residential battery storage.

There is no doubt that everything about the well-built Tesla home mobile power supply is great, but there is one main problem-Tesla's solution may cost you a few months' salary!

Many people have been attracted by Tesla's hype and have forgotten that Powerwall has other reliable home energy storage alternatives.

Fortunately, BSLBATT has a cheaper alternative to Tesla Powerwall, and you can still enjoy all the benefits of off-grid energy without spending too much budget on the power storage system.

What is the cost of a Tesla Powerwall?

Tesla's 13.5kWh Powerwall costs about US$7,800, and the cost per kilowatt-hour has reached US$577. This figure makes many homeowners who want to have a home energy storage system hesitate! Since the huge size of BSLBATT is 20 kWh, its cost per kWh is very low. The battery is also independent and has wheels. This means that almost any customer can install the battery and roll easily.

BSLBATT ESS (energy storage solutions) energy storage solutions based on lithium battery technology cover residential and commercial markets.

The Powerwall battery uses LFP technology, which is much safer than the lithium-ion battery in the Tesla Powerwall. LFP technology is relatively new, but looks very promising.

This product is a high-tech product developed in response to the requirements of new backup power sources. It has the characteristics of integration, miniaturization, lightweight, intelligence, standardization, and environmental protection. It can be widely used in indoor distribution stations, integrated base stations, and marginal stations. , Distributed power supply, home energy storage, and other fields.

A solar battery allows consumers to control their power consumption and where their energy goes. It also provides you with backup power in the event of an outage. Smart features associated with backup battery packs enable you, the consumer, to understand where your power is going and what steps you can take to lower your grid consumption.


The substantial benefits that Lithium-Ion technology offer over lead-acid technology means that using Lithium-Ion batteries is becoming an ever more popular choice. And you haven't done it yet, maybe that’s because you’re already adapted to the lead-acid solar storage system and still confused about this replacement process. To be honest, this is not as complicated as you think, and it brings the conveniences that you can’t imagine with lead-acid products. 

Just like all the battery replacement, if you want to replace your existing lead-acid battery or any other type of photovoltaic system, you need to consider your capacity, power, and size requirements, as well as making sure you have the right system. So is there anything else needed to think about?  

Wall-mounted home battery battery

When considering replacing existing lead-acid batteries by Lithium-ion batteries, one needs to take a couple of things into consideration. 

1)The inverter brand/Communication protocol.

If you want to gain all the smart functions that our powerwall battery can provide or you want to say bye to the power bill and sell electricity to the grid, please make sure that you have got or you’re going to buy the inverter which we’ve matched the protocols, so that you can make the full use of this intelligent device. 

Most existing inverter brands are compatible with our lithium iron phosphate wall-mounted powerwall batteries. Our Powerwall has matched with the brands of the inverter as following: Goodway, Growatt, Deye, Victron, East, Huawei, Sermatec, Voltronic Power, etc. If you’re using some other inverters, get contact with us to check whether we’ve matched or not. We are still in the process of matching new brands. Therefore even if it's not paired yet, we can also match for you, it takes about 1 month for the matching process.

2)The actual capacity you want.

You may discover that the lithium battery's capacity is generally lower than the lead-acid battery in most of the replacement cases. That's because, with the longer cycle life, Lifepo4 can be discharged deeper. Then our customers can save some costs by decreasing capacity without influencing the working hours. So please also noted that when upgrading from lead-acid to LiFePO4 batteries, you may be able to downsize your battery (in some cases up to 50%) and keep the same run time. Confirm the actual capacity you want, we can get back a more cost-effective solution to you.


3)The charging voltage.

To get the most from the Lithium-Ion batteries stay within the recommended operating conditions. Although the batteries are set up to do this automatically and safely, taking proper care of your new batteries will prevent nuisances during use such as Lithium-Ion batteries disengaging themselves (by a safety relay). The charge voltage of the battery needs to be checked and possibly changed. Where low charge voltage will result in incompletely charged batteries, overly high charge voltage will potentially push the Lithium-Ion batteries outside their allowed operating conditions. Also, don’t forget to clearly claim your charge&discharge current requirements, and series and parallel requirements when buying this wall-mounted battery.

Is there a clear-cut winner among solar batteries? 

Tesla’s Powerwall remains one of the most popular solar batteries produced, but that doesn’t make it a clear-cut winner in all categories. 

BSLBATT Powerwall battery packs covered above have viable applications. 

What battery will work best for your home will largely depend on your budget, your location, your personal energy consumption profile, and what additional features you’d like to see in your system.


By the way, since there is no fluid inside of LiFePO4 batteries. This gives you the flexibility to install these powerwall batteries where it is best suited for your application. 

Please contact our technical support if you need assistance with your upgrade and they will be happy to make sure you’re going through the right process.Are you looking for a cheaper alternative to Tesla Powerwall? From the perspective of price and performance, BSLBATT LiFePo4 battery seems to be becoming a strong competitor. If your budget is not enough, you can contact us for a cheaper solar cell solution!
