Residential

1. Enphase Energy

Enphase offers an AC plug-and-play system based on a lithium iron phosphate battery from Eliiy Power, with a 10-year warranty on two cycles per day. The battery offers greater than 95 percent depth of discharge. In October, the microinverter maker began offering its Home Energy Solution, an integrated solution combining solar generation, energy control and energy storage to Australian homeowners, the first country in its global roll out.

2. Orison

Orison, based in San Diego, recently announced that its residential, 2.2-kWh storage systems may be ordered for summer delivery via crowd-funding platform Kickstarter at a price of $2,000. The Orison system, based on Tesla lithium ion batteries, uses cloud communications to analyze utility rates, peak demand charges, weather, blackout alerts, local usage, as well as internal monitoring.

3. OutBack Power

OutBack Power’s FLEXpower Radian preconfigured system is built around the company’s Grid/Hybrid inverter/charger that includes programming, charge control, networking and other BOS components for solar energy storage. The system also can be paired with sonnen’s energy management software. OutBack’s system utilizes Nano-Carbon batteries that combine absorbed glass mat/valve-regulated lead-acid (VRLA) battery chemistries with cycling and performance characteristics that are more fault-tolerant and function in partial state-of-charge applications.

4. SimpliPhi Power

SimpliPhi Power utilizes safe, non-toxic lithium ferrous phosphate chemistry in its 3.4-kWh optimized energy storage battery. The 3.4-kWh battery is available in 24V and 48V and features proprietary architecture and a Battery Management System (BMS) that delivers a long cycle life without generating heat. A built-in accessible 80 amp DC breaker on/off switch increases safety and simplifies installations. Compatible with all industry standard inverter/chargers SimpliPhi’s LFP batteries are safe, non-toxic and require no AC or toxic liquid cooling.

5. sonnen

sonnen Inc. has almost 10,000 storage systems installed globally. With products that are engineered in Germany and made in the United States, sonnen’s goal is to provide clean, affordable energy for all. The sonnenBatterie eco system, coupled with solar, supplies homes with up to 100 percent of their energy needs, in addition to providing backup power for homes and taking advantage of different tariff structures for off-peak vs. on-peak use.

6. Tabuchi

Tabuchi’s EneTelus Intelligent Battery System (EIBS) is a solution that houses both an inversion unit and a battery as well as the transfer switch, which is usually something you’d have to mount separately. The battery has its separate box, but it is all developed together, which enhances the functionality of the entire unit. Tabuchi says the advantage of the system is its lithium ion battery. After looking at about 20 different brands, Tabuchi decided on working with Panasonic, which has a battery that can be cycled approximately once a day for 10 years — which is the length of the warranty.

7. Tesla

Tesla, based in Palo Alto, Calif., is offering its own lithium ion battery packs in the much-anticipated Powerwall, a 7-kWh configuration for $3,000, and 10 kWh for $3,500. The system offers 3.3 kW of continuous power and carries a 10-year warranty. The system is designed for either a daily cycle or a weekly cycle. Tesla is working with SolarEdge, Fronius and SolarCity, among other companies, for its national rollout.

8. Trojan Battery

Addressing the impact of partial state of charge (PSOC) on batteries, Trojan Battery offers Smart Carbon as a standard feature in its Industrial and Premium flooded battery lines. Smart Carbon is a proprietary Trojan formula that provides improved performance when the batteries operate in PSOC, enhancing overall battery life in off-grid and unstable grid applications where the batteries are undercharged on a regular basis. Along with increased life in a PSOC, Trojan’s Smart Carbon proprietary formula also provides improved charge acceptance and faster recharge in PSOC applications.

 1. Ideal Power

Ideal Power’s Grid Resilient 30-kW Multi-port Power Conversion System (30B3-4DF) utilizes the company’s patented Power Packet Switching Architecture in an AC/DC/DC configuration to directly integrate solar+storage, serving both grid-tied and off-grid applications. PPSA also provides transformerless isolation resulting in significant savings in equipment weight and size compared to conventional PV + battery solutions, dramatically lowering installation costs, while also dramatically improving operating efficiencies.

2. Princeton Power

The GTIB-100 G1.2 is a three-phase, 100-kW four-quadrant converter utilized in microgrid applications. Launched in 2009, it was the world’s first commercial-scale microgrid converter certified to UL-1741 safety standards. It is designed for advanced batteries, solar, on-grid and off-grid applications. The GTIB-100 is capable of operating autonomously in on-grid mode, detecting grid outages and transitioning to off-grid (island or microgrid) mode and transitioning back when the grid returns. Power quality in on-grid and off-grid modes meets IEEE 1547 guidelines.
