Sol Donum™ Low Voltage Energy Storage Services

“What would happen to your organization during an unscheduled power interruption or an extended power outage if you were unprepared? These can be very costly and are the reason why power protection is so important.”

We provide pre-engineered products and solutions for low voltage single-phase and three-phase energy storage systems and applications from 2kW to 45kW of output power. We apply our pre-engineered products and engineering capabilities for customer requirements to:

  • Design and build systems that support off-grid power, long-term backup, capacity firming/load management, power quality, and generator firming requirements to provide hours, days, or perpetual power generation. We currently offer:
    • Single-phase 120/240VAC and 220VAC
    • Three-phase 120/208VAC, 230/400VAC, 220/380VAC, and 240/415VAC 
  • Develop secure battery storage monitoring software and 5G/Wi-Fi enabled IoT framework services using our -Grid framework to improve operational efficiencies, decision making, and cost savings can be deployed to the customer’s cloud or through the internet and support third party services such as SNMP 
  • Develop electrical resilience contingency plans to maintain continuity of operations in organizations in case of natural disasters and critical incidents — site surveys & assessments, Continuity of Operations (COOP) & Resiliency planning, training, tests, and exercises (TT&E)

Why us:

  • Battery storage, power/electrical, and software engineering capabilities in one organization
  • Strong vendor partnerships and supply chain with component and battery cells manufacturers
  • We design low-risk solutions using safe lithium iron phosphate (LiFePO4/LFP) batteries and proven power conversion technology
  • Partnerships with established domestic renewable services providers
  • Customer technical support staff have reach back to all engineering teams

Whether it’s industrial refrigeration, whole building backup, renewables or generator firming, maintaining power quality, or working with CHP or hybrid off-grid systems — our services team can create a solution using our prebuilt products to meet your energy storage needs.

Our Vision

We develop portable, renewable energy generation and storage products focused on reducing fossil fuel dependency and supporting energy resilience – one village, one home, one business, and one user at a time.

Our portable, price-accessible technologies provide backup and off-grid power access to a wider consumer market. Our products are designed to increase consumer awareness, support renewable energy accessibility and adoption, and increase the ownership of renewable alternatives for energy generation and backup.

Sol Donum™ is an LLC founded by engineers and entrepreneurs who built their careers within the U.S. Federal Government, DoD, and Intelligence Communities. We’ve successfully operated several software and information technology services companies and have now turned our attention and applied experiences to renewable, portable energy technology – designed and built within the United States.

Unstoppable Power for Critical Applications

Made in the USA, the Vulcan is an expandable, battery energy storage system (BESS) for powering your home or small business.

It is a scalable and portable alternative to permanent fixture energy storage solutions. The Vulcan Inverter-Charger outputs 2KW of filtered 120V AC from solar panels, grid power, or other DC sources and stores energy in safe, high-energy Lithium Iron Phosphate batteries. The Inverter-Charger can run as a standalone system using its internal 1.4KWH battery and can also operate with one or more 2.6KWH or 3.6KWH Energy Stores to increase its overall capacity.

Unlike other home appliance grade systems that are permanently attached to your home or business, you can easily transport the Vulcan system with you as you commute, travel, or move. Unlike most portable systems that need replacement after a year or two, the Vulcan system is an investment that is built to last. We guarantee 10 years of daily use and offer the ability to refurbish your system even beyond the warranty.

Ingenuity & Reliability

Sol Donum™ is a battery energy storage and power disruptor with the Vulcan system that became available in June of 2021. Vulcan is unique in that it fits into the categories of both permanently installed and smaller portable systems due to the engineering and design of its power flow electronics and battery charging circuits. 

Vulcan is not a wall-mount permanent system, but rather a modular and portable system that can be installed on shelving or a floor. The base system itself contains a 1.4 kWh battery, a 2000 or 3000-watt pure sine wave 120V or 2000-watt 240V AC inverter, solar charge controller, and AC to DC charger for grid charging. Vulcan is durable to operate in a wide range of climate environments and can expand to over 100 kWh of battery capacity. The high-density Lithium Iron Phosphate batteries live up to 5000 cycles (or 10 years) at 80 percent depth of discharge, without decreasing in performance. 

Vulcan was designed and built with reliability, availability, and maintainability (RAM) as guiding principles:

  • Multiple AC-to-DC and MPPT chargers within each system ensure redundancy so that system charging capabilities are always present
  • MPPT chargers in each unit allow for solar optimizing with panel groups so that charging continues if some panels are shaded or damaged
  • Automatic power-sharing ensures that damage to any battery unit does not affect the overall system’s ability to continue operations while the battery unit is being replaced or repaired
  • A second Inverter-Charger unit can be added to ensure continued AC power generation if one unit fails or to double the output if more AC power is required
  • Simultaneous charging from AC and Solar inputs to reduce charging times by a factor of 2X
  • Automatic circuit protections ensure overload, short circuit, and low battery conditions are easily and automatically recovered
  • All AC plugs feature waterproof covers for further protection against moisture and dust penetrations
  • All AC inputs and outputs feature electromagnetic interference filters (EMI) to protect critical appliances, electronic circuits, and systems
  • Each unit features our advanced battery management system (BMS) that protects against overcharge, over-discharge, high and low-temperature charging, and short circuits.
  • A subsystem-based architecture allows for component replacement and upgrading without sacrificing the entire unit
