Solar batteries are ideal for storing excess power generated by your solar panels. This energy storage will allow you to access that stored power at a later date.
When choosing a solar battery, it’s important to take into account both your power needs and budget. Furthermore, be sure to assess the warranty options available.
1. LG Chem RESU 10H Solar Batteries
The LG Chem RESU 10H is one of the top solar batteries on the market. As a DC-coupled battery, it can receive power directly from solar panels without going through an inverter first.
The battery is highly rated in terms of round-trip efficiency and depth of discharge, which allows it to transform incoming electricity into stored energy. These attributes make it one of the top solar batteries available today.
Additionally, LG’s RESU Monitor tracking software backs the battery system, giving homeowners real-time updates about their battery’s health and performance. It also enables them to communicate with their installer if there are any issues with the battery.
2. Enphase IQ Solar Batteries
The Enphase IQ Battery is an AC-coupled solar battery system designed to work with grid-tied solar panel systems for backup power. It stores excess energy generated during the day so you can access it at night or during a power outage.
IQ batteries are composed of lithium iron phosphate (LFP) battery modules, which offer superior safety and longevity compared to cobalt-based lithium-ion batteries. Plus, these IQ batteries boast 100% depth of discharge (DoD) and 89% round-trip efficiency.
IQ batteries can be used with any IQ microinverter solar system to maximize power production and store energy for later use. Their modular design means you can install multiple IQ batteries for the required storage capacity at home.
3. SolarEdge Home Battery
The SolarEdge Home Battery is an ideal choice for homeowners seeking to add solar and storage capabilities to their residence. It boasts a stylish design and industry-competitive power rating.
This battery is designed to store energy produced by solar panels so your home remains powered during a power outage. When it’s time for use, excess power from the battery will be sent through an inverter and converted to alternating current (AC) electricity that your house can utilize.
The SolarEdge Home Battery is the perfect solution for a smarter home, offering industry-leading efficiency and seamless integration with other SolarEdge products. This enables you to control and manage all your home energy needs from one app.
4. SolarEdge Eco Solar Batteries
SolarEdge offers a complete home energy ecosystem that enables homeowners to manage and monitor their solar power production, consumption and backup storage from one app. The SolarEdge Home Hub Inverter, Power Optimizers, Home Battery Backup Interface as well as Smart Energy Devices like EV Chargers, Hot Water Controllers and Load Controls are all integrated into this app for seamless control.
It is NEMA 3R-rated and compatible with 3-phase SolarEdge Home Hub and StorEdge-RWS inverters!
This system also features rapid shutdown, LCD display and module-level monitoring via Internet connection, Ethernet or wireless. This is an ideal choice for homes looking to add solar storage while still remaining connected to the grid.
5. Tesla Powerwall 2
If you’re considering self-powering your home from the sun, Tesla Powerwall 2 is one of the top solar batteries on the market. It’s easy to install and comes with a mobile app that lets you manage energy usage and stored amounts easily.
The Tesla Powerwall 2 offers high power capacity, excellent drain-off efficiency, and efficient power cycling. Furthermore, it qualifies for the 30% federal tax credit on battery storage added to solar systems or standalone solar batteries.
Powerwall 2 battery packs can be ordered online through Tesla or from various solar and storage installation companies for between $12,400 and $11,550 full installed (after 30% federal tax credit is applied), though you may receive discounts if you purchase multiple batteries at once.
