Safe, eco-friendly battery technology
e engineers at Fortress Power announce the New Generation of its eVault battery (G2LFP-15kWh). Fortress eVault series uses Lithium-Ferro-Phosphate technology instead of Lithium-Nickel-Manganese-Cobalt (LNMC), which is a safe, eco-friendly technology o ering better operating temperature, signi cantly more life cycles, and a high peak power output. e new battery is user friendly with a front display showing the State of Charge (SoC) and the battery voltage. e battery is compact and can be stacked
5 in parallel, to achieve 75kWh. Each battery communicates with each other via RS-485 cable to balance the charging capacity when they are connected in parallel. ese new units will be available in November. All Fortress batteries have a 10-year warranty with 6000 cycles. e batteries
are designed to work with commonly used 48V chargers/ inverters such as Schneider, Outback, Magnum, Darfon, and SMA among others. e long cycles enable Fortress batteries to support backup, time-of-use, self-use, and o - grid applications. Currently Fortress o ers 10 and 15kWh in North America, which are scalable to 20 and 30kWh.

Maximize charging options for drivers while reducing operational costs eMotorWerks’ JuiceNet Enterprise solution simpli es management of electric vehicle charging stations across multiple sites. By deploying both smart-charging EV supply equipment (EVSE) and cloud software solutions on a commercial scale, electric vehicle eet owners and facility managers are able to remotely manage eets
of chargers at various locations from a single cloud dashboard and maximize EV charging capabilities
on their properties. rough the dynamic load balancing control of the JuiceNet Enterprise solution, EV owners can install more stations on their property without costly electrical upgrades to their building infrastructure, balancing the charging load in real-time to match site electrical capacity. In addition, JuiceNet Enterprise enables EV drivers and building managers
to optimize renewable energy use by aligning charging when solar and wind generation are most abundant
on the grid. e solution allows customers to reduce onsite peak electricity demand charges by sharing loads between chargers throughout the day, while ensuring vehicles are charged when needed. e system also empowers drivers to locate available stations within their network on the JuiceNet mobile app. JuiceNet Enterprise allows deployed stations to automatically shift power use to nighttime hours, when prices are
low, or curtail charging during peak afternoon times. rough JuiceNet Enterprise, eet operators gain exible con guration, reporting, and noti cations, such as the ability to con gure charger settings across the network, by customer account, location, or individual station. e bene ts of JuiceNet Enterprise also extend to a regional utility level, allowing eets of JuiceNet- enabled EV chargers to aggregate charging loads and respond to demand response programs, helping to bring greater stability to the grid during peak load times.

DC coupled solar + energy storage solution
Alencon Systems LLC’s SPOT (String Power Optimizer and Transmitter) is a string level DC-DC optimizer which optimizes the power from PV string inputs with voltages ranging from 600V to 1500V. e SPOT-ES family of products has been speci cally designed for the needs of DC-coupled Solar + Storage deployments. e SPOT-ES V5 includes
a true 1500V input based on 1700V rated Silicon Carbide (SiC) rated mosfets, an ability to map a wide battery charge/discharge voltage range, reliability enhancements developed in concert with Solar + Storage technology providers and integrators, as well as exible communications options for better integration with Solar + Storage and Microgrid control systems. e SPOT-ES’s galvanic isolation concept isolates the PV input from the output by attaching isolation transformers to each PV input. is technique provides a unique bene t in the DC-coupling of Solar + Storage because the integral magnetics to the SPOT can be easily con gured from one deployment to another to easily support
a broad battery charge/discharge DC-bus voltage, where the voltage range could vary by as much
20% from complete discharge to full charge. e SPOT-ES V5 includes an ultra-fast circuit to protect it from sudden system power output overloads. e SPOT-ES V5 features enhanced communications features to allow it to be interfaced with third party system controllers via either Modbus TCP, for communicating to the SPOTs wirelessly, or Modbus RTU, which allows for hardwire communication to each SPOT directly. e enhanced communication functionality o ered in the SPOT-ES V5 allows for granular control over the PV, including the ability to curtail production at the string level.
