All-inclusive residential energy storage
The SMA Energy System Home delivers value to homeowners through backup power and energy management functionality, and simplicity to solar professionals with a complete, single-sourced solution for residential energy storage. The SMA Energy System Home includes a Sunny Boy 6.0-US battery inverter and a10kWh battery from BYD. The system is available in two variants. The first includes the fully integrated Automatic Backup Unit, which simplifies installation for backup use cases. Whole-home backup can quickly and easily be achieved, or specific loads can be identified and protected. The second variant is for users exclusively focused on home energy management. This allows users to optimize rates and power consumption, as well as participate in unique markets with zero export grid requirements. Furthermore, even systems designed for energy management come with SMA’s exclusive Backup Lite feature, which allows users to access 2000W of available power via a manual switch. Up to three high-voltage batteries can be connected to a single Sunny Boy Storage-US, simplifying installation, reducing labor, and cutting balance-of-system costs. The AC coupled architecture allows for new PV or retrofit installations. The system pairs with the Sunny Portal PV monitoring platform to monitor and control home energy usage. SMA Smart Connected is a proactive service solution provided with the SMA Energy System Home. Smart Connected ensures uptime is maximized for the homeowner while service truck rolls for installers can be cut in half.

Hybrid energy solutions
Darfon America Corp.’s energy storage products have improved features and functionality. Among the models upgraded are the H200 and H300 hybrid energy storage systems and the H5001 hybrid inverter. The H200 is an energy storage solution that integrates lithium batteries and the H5000 hybrid inverter into a 19" industrial enclosure. The H200 now offers Panasonic LNMC and Dragonfly LFP as battery options. The wiring terminals have been relocated
to the backside of the H200 for easy access and speedy installation. The distribution panel was also redesigned with micro breakers thus making it more compact and increasing the battery bay space to allow up to 30kWh of battery storage. The H300 is a wall-mounted energy storage solution consisting of the H5001 hybrid inverter and a 5kWh LNMC battery. The H300 solution is now available in a 10kWh configuration using two battery packs and a master box. The H5001 hybrid inverter has undergone some physical changes including a lockable distribution box and lockable external PV disconnect for extra security. The conduit knockouts are laser-cut for easy removal and consistency in size. Also, the access cover is easier to remove for installers to program the AP registers. In all three models, the hybrid inverter fans have been upgraded for more precise temperature control. The hybrid inverters have also been improved to handle in-rush overload with 120V circuits. There is also an optional generator start-up kit, if needed.

Giga-scale cryogenic battery
Highview Power has developed, in partnership with Finland-based Citec, a modular cryogenic energy storage system, the CRYOBattery, that is scalable up to multiple gigawatts of energy storage and can be located anywhere. This technology reaches a new benchmark for a levelized cost
of storage (LCOS) of $140/MWh for a 10-hour, 200MW/2 GWh system. Highview Power’s cryogenic energy storage system is equivalent in performance to, and could potentially replace,
a fossil fuel power station. Highview Power’s proprietary cryogenic energy storage technology, which uses liquid air as the storage medium, provides all the services essential for a robust grid including time shifting, synchronous voltage support, frequency regulation and reserves, synchronous inertia, and black start capabilities. Highview Power’s CRYOBattery can be sited almost anywhere. The CRYOBattery has a small footprint, even at multiple gigawatt-levels, and does not use hazardous materials. Highview Power has developed and optimized its own proprietary BLU core controller system. The BLU controller enables a system to be configured to
a particular application through the selection of individual operational modes. It also provides operation and performance monitoring feedback, ensuring a facility’s optimal efficiency. The system’s embedded flexibility further ensures
that the controller has the built-in capacity to adapt as a facility’s demand varies with market development. Highview Power recently won the 2019 Ashden Award for Energy Innovation with its proprietary CRYOBattery technology.
