What follows are the Top Solar Storage Products for 2019. We separate them into small-scale (typically residential) systems and large-scale storage. We also feature some battery accessories (like charge controllers). Take a look at this year’s innovative products (listed alphabetically by company) within the energy storage and battery category for the solar industry.
See the full list of the 2019 Top Solar Products here.
Use your residential solar system and power critical loads on and off-grid with the ABB Universal 10/4 solution. The Universal 10/4 is capable of simultaneous AC and DC coupling, continues operating during grid outages, comes with an ABB solar inverter, and accepts charging from multiple AC and DC sources.
The Electriq PowerPod is a fully-integrated home energy storage, management and monitoring system that includes lithium-ion batteries and a hybrid solar/battery inverter controlled by intelligent software. When paired with solar, the PowerPod can self-consume and export excess power back to the grid.
Fortress Power eVault 18.5-kWh is one of the single most powerful solar storage batteries on the market. It uses proved lithium-iron phosphate technology, offers a user-friendly digital display for monitoring of remaining capacity and power output. More compact and affordable, the eVault powers up to 12 stacks in parallel (222 kWh).
The Yeti Tank and Link expansion module is a proprietary technology that allows consumers to chain lead-acid and lithium batteries together — previously not possible. Paired with Goal Zero’s Yeti power stations, this allows consumers to scale based on the individual power needs for a fraction of the typical cost.
The LG Electronics Energy Storage System is a state-of-the-art home energy management system. The LGE ESS features quick and easy installation for installers, a compact and elegant design, a reliable, scalable LG Chem lithium-ion battery and an integrated smart energy management system. Offered in both AC-coupled and DC-coupled configurations.
Built with lithium iron phosphate, the NV14 Solar Home Battery is safe and long-lasting. Its 14.4 kWh capacity powers a home for up to 18 hours. Unlike competitors, the NV14 is expandable to a 24 kWh capacity without an extra inverter and connects to either AC or DC solar panels.
The Panasonic EverVolt is a flexible energy storage system compatible with any solar system or inverter. A premium offering from the industry’s largest battery producer, EverVolt features a modular design and is available in AC- and DC-coupled versions, offering a flexible solution optimized for homeowners’ energy needs and budgets.
Rolls Battery offers flooded and sealed deep cycle batteries in a wide range of voltage and capacity options. The popular 6-volt S6 L16-HC (445 Ah) flooded model is the go-to solution for installation professionals and homeowners seeking reliable and scalable energy storage for use in residential off-grid and battery-backup applications.
Adaptable and scalable, Conext XW Pro, certified to Rule 21, provides the one solution you need for solar with storage, backup power or off-grid systems. The XW Pro provides high reliability, drawing on its high surge power rating, integrated transfer switch for continuous power supply, and optional backup generator integration.
The latest evolution of SimpliPhi’s popular turnkey, indoor/outdoor AccESS energy storage and management system combines SimpliPhi’s highly efficient energy storage with the Sol-Ark DC transformerless hybrid inverter to deliver operational efficiencies in size, weight, power and energy capacity that are supported with an interactive user software interface.
The SMA Energy System Home represents the company’s most complete storage offering for North America to date, delivering value to homeowners through backup power and energy management functionality, and simplicity to solar professionals with a complete, single-source solution for residential energy storage.
Trillium, Trojan’s intelligent lithium battery, features more runtime, lifetime and peace of mind. Trillium is available in three popular sizes for solar applications. From its superior cell and battery design to its intelligent, built-in diagnostics, Trillium offers a life expectancy over 5,000 cycles and will deliver return on investment.
Ampt String Optimizers are lowering the cost and improving the performance of large-scale PV + DC-coupled energy storage systems. Ampt optimizers perform string-level MPPT, allow DC:AC ratios up to 3:1, and enable high- and fixed-DC bus voltages to eliminate 50% of electrical BOS components while lowering inverter and BESS costs.
ESS Inc.’s 100-kW/400-kWh Energy Warehouse (EW) iron flow battery is a durable, environmentally safe, long-duration energy storage solution. The 4+ hour system is designed for time-shifting renewables, increasing resiliency and managing demand. Its 25-year life span complements solar and wind projects, with minimum maintenance and low levelized cost of energy.
The Mark 1 has been designed from the ground up to be an optimized energy storage platform capable of delivering industry-leading 110.7 kWh while operating in the 1,500-V class. High density and high voltage equals lower installation and operational costs at higher efficiency.
The SMA DC coupled storage solution is built for new PV plants, but it can be used to retrofit PV plants for those operators who want to enjoy the benefits of solar-plus-storage. In many utility-scale applications, DC coupling can offer significant operating cost and efficiency advantages over AC-coupled systems.
Viking Cold Solutions’ long-duration Thermal Energy Storage (TES) solution utilizes phase change material and intelligent controls to reduce up to 95% of grid-sourced energy during off-solar hours, improve temperature stability, and maximize energy efficiency in low-temperature cold storage facilities. TES maximizes solar returns with an LCOE < 2¢ per kWh.
Proven over two decades of use and continuously improved. For off-grid PV systems up to 1,100 W. All versions have TrakStar technology and load control. Advanced thermal engineering eliminates cooling fans for maximum efficiency and longer life — a breakthrough in this power range. Available in 25A or 40A, up to 120Voc.
The Conext MPPT 80 600 charge controller offers top performance with the reduced installation time and balance of system costs for DC-Coupled solar with storage. Compatible with 600V PV arrays, the MPPT 80 fully integrates with the XW Pro and includes a shade-tolerant MPPT algorithm and optimized battery charge profiles.
