Having a solar power battery storage system is essential if you have a solar panel roof or even just grounded solar panels. A downside is the price. A Tesla Powerwall can be expensive to some, which prompts #### Consumers to look for alternatives that have a similar performance. Let’s take a deep dive into excellent choices that work just as well from other companies.
What is a Tesla Powerwall?
What exactly is a Tesla Powerwall and what does it do? It’s Tesla’s version of a solar energy storage unit that is rechargeable. It’s also referred to as an AC battery and the unit can be wall mounted for aesthetic purposes and convenience.
There are two components within a Tesla Powerwall - the AC inverter and the lithium-ion battery pack.
The battery pack is what stores your solar energy and the AC inverter is what converts the energy to electricity and delivers it to your home power grid.
Is a Tesla Powerwall Worth It?
It sounds very technologically advanced, which is no surprise why the Tesla Powerwall commands a high price - but is it worth it? For the 10K you need to cough up to get the unit and to install it, we understand why many people are hesitant to shell out that money.
If you have a Tesla solar roof, then we would say it is worth it for a seamless integration. Even if you don’t have Tesla solar panels, a Powerwall is a good investment. However, there are more wallet-friendly options on the market that could do the job as well.
Top Alternatives to the Tesla Powerwall
We kick off the list with the LG RESU Prime. LG is a well-known brand that produces anything from home appliances to smartphones. There are 2 RESU Prime options - the 16H and the 10H. We recommend the 16H for whole home backup power, and this capacity also happens to be the world’s largest at the moment.
The 10H has a 9.6 kWh, which is optimal for daily use and both capacities have remote battery monitoring. The RESU batteries charge up during the day and power your home at night. The 16H has a larger profile than the 10H, so other than taking into account what capacity you want, you also have to look at the space you have.
With your choice of either, you can rest assured knowing that you are prepared against power outages from extraordinary weather conditions and you can cut back on your electricity bills.
- Excellent for daily use
- 2 capacities
- Be prepared for power outages
- Save on utility bills
- Detachable Control Unit
- Dividable modules for easy installation
- Reliable brand
- Not too much cheaper than a Tesla Powerwall
Why We Like It
We love the detachable modules which makes installation and maintenance much easier than single units. There are also two capacities to choose from to better match your unique needs.
For residential battery storage, Alpha ESS has the Smile line. They each have varying capacities:
Smile-B3 - 3000W/2.9-17.2 kWh
The B3 has lithium iron phosphate batteries, which makes it the safest among all lithium batteries. The battery storage unit is compatible with both DC and AC coupled installations and provides multiple operation modes. It’s another modular design that is easy to maintain and install. Plus, the unit offers 24/hr monitoring.
Smile-B3-PLUS - 3000W/5.04-30.24 kWh
The B3 PLUS offers much of the same with a higher capacity than the regular B3 unit.
Smile5 - 5000W/2.9-80 kWh
The Smile5 comes complete with the features of the previous two tiers but with additions such as self #### Consumption, visualization features, and a very long lifespan.
Smile-S6-HV - 6000W/49.5 kWh
The-S6-HV is where things get a bit more advanced. The unit is outfitted with Class II lightning protection circuitry along with photovoltaic utilization.
Smile-T10-HV - 10,000W/8.2-49.5 kWh
Lastly, the Smile-T10-HV is super heavy duty and offers lightning protection as well as a phase unbalance function.
The brand also has commercial and industrial energy storage solutions, which edges out some of its competitors.
