Over 70% of our product parts are North American made, mitigating the supply chain risk, and we make every effort to continue producing and delivering our products on time. We will update you if our timeline changes.
- Question: Is there any extra shipping fee and custom fee for certain areas/countries?
The shipping costs will be added automatically to your bill on the payment page. Please check it before you pay.
- Question: Will you ship to my country?
Currently, we are only shipping our Vulcan and Energy Stores to the USA, Canada, and Mexico. Our product is currently only available in these countries. We plan to develop a 240V product for other countries.
- Question: I’m not an electrician. Will I be able to set up and operate the Vulcan?
The Vulcan was designed to be a turnkey plug and play system and does not require an electrician. There is no installation required. Our plug and play system makes it easy to use our system right out of the box! Simply plug the Vulcan System to your power source (Solar or Grid) and plug in the devices you want to use with the Vulcan. If you would like to use our system with a generator transfer switch, we recommend hiring an electrician for a more seamless and cleaner integration. Moreover, our customer support specialists and online resource center are available to answer any integration questions you may have.
- Question: Do I need a permit to operate and purchase your system?
Our Vulcan and Energy Stores do not require a permit to purchase or operate unlike the permanent installation systems, removing the lengthy and arduous process of obtaining permits.
- Question: What is the surge power of the Vulcan?
The Vulcan has a surge power rating of 4,000W and can easily handle any 15A inductive load. Two (2) Vulcan Inverter-Chargers can be chained together through Energy Stores to provide up to 8,000W of surge power and 4,000W of continuous power.
- Question: How long will the Vulcan run my device?
A general formula for determining the duration for which a Vulcan system can run your device is to take the watt-hour usage of the device, divide it into the watt-hour capacity of the system and multiply that by the system inverter efficiency of 91.5%.
For example: A 21 cu. ft. Energy Star refrigerator that has an average energy usage of 71WH can be run for ((5000/71) * 0.915) = 64 hours.
- Question: What’s the operating temperature of the Vulcan and Energy Stores? How low of a temperature can you run it?
The Vulcan can operate from -20°C to 50°C (-4°F to 122°F) with built in safety to prevent operation outside of these temperature ranges for safety and longevity of the product. Once the temperature rangers are back within operating range, the Vulcan will automatically charge the batteries for use.
- Question: Does operating temperature really matter?
Yes, the recent events of the 2021 winter storm in Texas shows us that operating temperatures are an important factor when choosing the right product. Most backup power systems failed to run due to limited operating temperatures of 0°C to 40°C (32°F to 104°F), rendering them useless. The Vulcan was designed to run in the toughest of conditions. It has one of the highest and lowest operating temperature ranges on the market from -20°C to 50°C (-4°F to 122°F).
- Question: What appliances can the Vulcan run? Can the Vulcan run an air conditioner?
Yes, the Vulcan can run any appliance that plugs into a three (3) pronged, 15A 120V wall outlet as long as the appliances are less than 2000W. Please be sure to check your appliance ratings.
- Question: Are the Vulcan batteries safe? Don’t Lithium batteries overheat sometimes? What battery chemistry do you use?
The Vulcan uses top of the line Lithium Iron Phosphate Batteries (LiFePO4). This specific chemistry is the safest battery chemistry for lithium batteries. This chemistry has superior thermal stability providing higher safety, incombustibility (won’t explode) and runs at much cooler temperatures. These batteries are not prone to thermal runaway. It can withstand high temperatures and is not flammable like other lithium batteries. These batteries come with an added bonus of a longer life cycle, efficiency, and charge time. Lastly, our battery management electronics constantly monitor the battery temperature to ensure safe charging and discharging.
- Question: How long will the battery last unused? If I were to just store it for use in an emergency what would I need to do to maximize the life of the battery?
The batteries will maintain a usable State of Charge (SOC) for 1 year or more with the power buttons turned off. However, they may be maintained indefinitely if they are plugged into a wall outlet. The maintenance energy draw is approximately 6 watts for an Energy Store and 6 watts (Unit Off) and 14 watts (Unit On) for the Inverter-Charger.
- Question: Is it possible to increase the life cycle(%) of the product?
The products are designed to ensure the greatest life cycle % of the batteries. If the units were continuously charged and discharged every day the batteries would provide a product lifespan of 13 years and 7 months estimated before the batteries were degraded to an 80% SOC. The system would still be usable but at a diminished storage capacity.
- Question: After the stated 5,000 battery cycles, how much capacity is left? Does the overall capacity just go down to like 80% after that amount of time?
The capacity degrades over time as the batteries are charged and discharged. The more a battery is cycled the faster it will reach the 80% SOC rating. 80% represents the average resultant capacity at the point of maximum cycles of use.
- Question: Can you charge the Vulcan or Energy Stores using Solar and Grid (AC Power) simultaneously?
Yes. You can charge the Vulcan and the Energy Stores from Solar and Grid power simultaneously.
- Question: Is there any chance to somehow build into the firmware the option to charge the units only to a certain percentage?
There is no need to charge this battery chemistry to any specific ranges. Unlike lead acid, NiCad (nickel–cadmium) or other battery types, Lithium Iron Phosphate batteries are not susceptible to deep discharge damage and charging memory. They are designed to be fully charged and discharged over and over again during the rated 5000 cycles life. Therefore, the systems are designed to store and produce the greatest amount of energy at the highest levels of efficiency.
- Question: What’s the difference between the Vulcan and the Energy Store?
The Vulcan Inverter-Charger is the main system unit and can generate 120V AC at 2000W continuous and 4000 watts peak. The output powers devices and appliances that use a 15A three-pronged plug. This unit contains an internal battery and charging components as well.
The Energy Store is used to provide added battery capacity to the system. The unit contains an internal battery and charging components and sends its energy to the Vulcan Inverter-Charger unit. Adding additional Energy Stores allows you to incrementally increase your system storage capacity up to 30.2KWH.
- Question: Can you chain multiple Vulcans or Energy Stores together for high battery capacity and higher surge capacity?
Yes. We have designed the system to be scalable and can be chained together in a variety of ways depending on the consumer’s needs. The configurations are endless, but we recommend a chaining limit of 30.2KW.
- Question: When the battery of the Vulcan and Energy Store are low, which unit takes precedence in charging? Can they be charged at the same time?
Yes. The systems can be charged at the same time or separately since they have their own independent charging circuits. The system will also balance out all batteries across the entire system to ensure that no unit is depleted below the other.
- Question: How frequently do I need to use or charge the device?
The product can operate on a single charge within a one year period or operate within daily use/charging patterns. If the product is planned for long term storage for more than 6 months, it is recommended that the units are charged once every 6 months to maintain optimal battery State of Charge (SoC).
- Question: What is the charge time from depletion of battery?
Our Vulcan and Energy Stores are easy and quick to charge from depletion. It takes roughly 2 hours to charge a Vulcan and 3 hours to charge an Energy Store with 1,200W of solar panels.Due to our scalability, the 3 hour system charge time from depletion remains constant with more panels added. Maximum AC charging times are 9 hours or less for the Energy Store and 4 hours or less for the Inverter-Charger. The charging times will remain below these thresholds regardless of the number of Vulcan or Energy Store units chained together as long as you have the energy to charge them.
- Question: Is there a built-in protection (solar controller) against overcharging from AC/DC/Solar? At what voltage is that figure calculated?
The Vulcan contains MPPT charge controllers and a separate AC/DC chargers that charge system batteries to 14.4V and idle the batteries at 13.6V. This represents a 100% charge in the system.
- Question: What is the depth of discharge (DoD)?
The batteries can be discharged up to a rate of up to 3C (300A for 20 minutes). However, the DoD depends upon the constant rate of current being drawn from the batteries. The combined capacity of the 5KW system is 382AH. For example, if the rate of discharge is 50A for 20 minutes, then the DoD equation is DoD% = (((50A*(20min/60min)) * 100%) / 382AH
This results in a DoD of 4.36% at a rate of 50A for 20 minutes.
- Question: Will the Vulcan automatically switch to solar charging during days or do I have to manually turn it on in the morning?
The Vulcan will automatically switch to solar charging when the panels are harvesting energy and if the battery requires charging or if there is an AC load on the system. No manual intervention is required.
- Question: Does the Vulcan also operate as a UPS?
Yes. Vulcan contains a 30A automatic AC transfer switch that passes grid power through the system and automatically switches over to battery power when the AC input is lost.
- Question: Does the Vulcan have an Automatic Transfer Switch? If it does, how long does it take for the ATS to switch to over?
Yes. Vulcan contains a 30A automatic transfer switch (ATS) that is suited for all loads, inductive and non-inductive. The ATS switch over time is 0.02 seconds (20 milliseconds).
- Question: Will you be selling solar panels?
Yes. Coming soon; we plan to sell solar panels.
- Question: Can I use any solar panels?
Yes. We have tested our product with panels from various vendors. However, you may choose and series connect any solar panels that allow for a combined Open Voltage output of up to 150V for the Energy Store and up to 100V for the Inverter-Charger (as long as the per panel Open Voltage is greater than 18V). Our units accommodate a native MC4 plug to connect directly to the solar panels cable so no special adapters or connectors are required to tie in your panels.
- Question: What’s the frequency?
The Vulcan can be ordered as a 50Hz or 60Hz at 120V AC system.
- Question: What is the noise level of Vulcan?
The Vulcan system cooling fans range from barely audible to a maximum noise level that is comparable to a desktop computer fan when running at maximum speed. The sound will not adversely affect standard room sound levels or conversation discussion levels.
- Question: Any kind of water-resistance for this product?
Our product was designed to operate under multiple temperature and humidity conditions and is IP52 and NEMA rated. This means the unit is water resistant and can be operated under cover in moist and humid environments.
- Question: How does Faraday Shielding work?
Faraday shielding routes the electrical energy induced from a radio frequency signal into an earth ground distributing the electric charge and canceling it out.
- Question: Is the Vulcan susceptible to EMP?
The Vulcan has an option to include a 17,000 AMP EMP Transient Voltage Suppression Devices, which shields all internal circuitry and AC loads. These EMP Transient Voltage Suppression devices meet the MIL-STD-188-125-2 specifications.
- Question: Does the Vulcan output pure sine wave?
Yes. The Vulcan outputs a pure AC sine wave at 120V.
