The LG Resu 16H Prime is LG's largest battery in their Resu lineup, holding up to 16 kWh. The typical efficiency rating of batteries we looked at was 90%. The EcoLinx is also the least efficient battery we reviewed, with a round-trip efficiency of 81.60%. The downside is the EcoLinx is significantly more expensive than other batteries we looked at, costing more than $30,000 before installation. This battery offers plenty of extra bells and whistles too, including smart home energy automation, energy tracking, smart weather forecasting and more with the Sonnen app. The Sonnen EcoLinx has an incredibly high depth of discharge rating (the amount of energy you can draw from the battery without causing damage) at 100% and has a decent on-grid continuous power output (how much power a battery can output at all times) of 7 kW. Every other battery we looked at had a 10-year warranty, and with batteries all facing a limited lifespan, the exceptional warranty on the EcoLinx set it apart. Both models include an outstanding 15-year/15,000-cycle warranty. You can also go with the EcoLinx 30, which holds up to 30 kWh. This means your battery capacity is extremely flexible.

The EcoLinx 1.5 holds between 12 kWh to 20 kWh and allows you to upgrade your battery capacity in increments of 2 kWh by inserting a battery module into the battery cabinet instead of installing an entirely new battery. The main difference between the two is the battery capacity. Sonnen offers two models of the EcoLinx: the EcoLinx 1.5 or the EcoLinx 30. California's new net metering policy that went into effect April 2023 ( NEM 3.0), for example, lowers the value of solar credits by 75%, making the idea of solar storage more attractive.

Some states have even begun making changes to their net metering policies, lowering the purchase rates of solar credits.

Installing solar storage with your panels decreases your reliance on the power grid, allowing you to still have power during outages, use solar energy to power your home at night (instead of buying electricity from the power grid) and even go off-grid entirely. Solar batteries are useful for more than just saving you from expensive time of use rates. There are two ways you can avoid letting your extra energy go to waste: sell it to the power company (if you have net metering) or store it in a solar battery to use for later. So what exactly can you do with this extra energy? And how can you get electricity when your solar panels have a slow day? When your solar panels are performing at their best, they might generate more electricity than you need.
