Ordering & Shipping
Do you offer free shipping?
Yes — all orders ship free within the United States. This includes large, heavy freight items like inverters, battery pallets, and solar panel packs. No minimum order value required for free shipping.
How long does shipping take?
Most in-stock items ship within 1–3 business days. Delivery typically takes 4–7 business days ( Monday - Friday) depending on your location and the size of the order. Large freight orders (pallets, heavy inverters) may take slightly longer. You will receive a tracking number as soon as your order ships.
Do you ship outside the United States?
Currently we ship within the US only. We are actively working on international shipping options — check back soon or contact us to be notified when international shipping becomes available.
How are large items shipped? Do I need to be home?
Heavy items such as inverters, battery systems, and solar panel pallets are shipped via LTL freight. For freight deliveries, we strongly recommend having someone present to inspect the shipment and sign for it. Please inspect packaging for visible damage before signing. If damage is visible, note it on the delivery receipt before accepting.
Can I track my order?
Yes. Once your order ships, you will receive an email with a tracking number. You can also track your order anytime at our Order Tracker page.
Do you charge sales tax?
VoltEdge Industries is registered in Wyoming, which has no state sales tax. For most customers shipping to addresses outside Wyoming, no sales tax is collected. Tax rules vary by state — if your state requires use tax reporting on out-of-state purchases, that responsibility falls to the buyer.
Products & Compatibility
Are your products certified for use in the United States?
Certifications vary by product. Each product page lists the specific safety
certifications that apply to that model — such as UL or ETL listing and the
unit's IP rating. If you need the certification document for a particular
product, contact us and we'll provide the manufacturer's certificate.
Will your inverters work with my existing solar panels?
In most cases, yes — our inverters are compatible with standard solar panel configurations. The key parameters to match are your panel string voltage (make sure it falls within the inverter's MPPT input range) and your system voltage (48V is the most common for our larger inverters). Contact our support team with your panel specs and we'll confirm compatibility before you order.
Can I add your batteries to my existing solar system?
Our 48V LiFePO4 server rack and Powerwall batteries are compatible with most 48V hybrid inverters. If you have an existing system, contact us with your inverter model and we'll confirm which batteries are compatible. We do not recommend mixing battery chemistries (e.g., adding LiFePO4 to a system with existing lead-acid batteries).
What size inverter do I need for my home?
For a typical American home (1,500–2,500 sq ft) with standard appliances, a 6kW–12kW split-phase inverter is usually sufficient. For homes with central air conditioning, electric water heaters, or EV chargers, a 12kW–18kW system is recommended. Our team can help size your system — call us or use the Trade Pricing form to describe your load requirements.
How many battery modules do I need?
As a general rule, most homeowners want at least 10–15kWh of usable storage for meaningful overnight backup. A single 5.12kWh Powerwall gives you basic backup for lights and essential loads. Two units (10.24kWh) handle a full day of moderate usage. Four units (20.48kWh) support high-consumption households or multi-day backup. Contact us to calculate the right configuration for your specific usage.
What is a split-phase inverter and do I need one?
Most American homes run on 240VAC split-phase power — two legs of 120VAC that combine to power 240V appliances like dryers, HVAC, water heaters, and ranges. If you want your inverter to run your whole home including these appliances, you need a split-phase inverter. If you only need to power 120VAC loads (lights, refrigerator, small appliances), a single-phase unit is sufficient.
Returns, Warranty & Support
What is your return policy?
We accept returns within 30 days of delivery for items in their original, unused condition and original packaging. Freight shipping costs for returns may be deducted from your refund for large items. Contact us at support@voltedgeindustries.com to initiate a return.
What warranty do your products come with?
Warranty terms vary by product type: Solar panels carry a 25-year performance warranty. Inverters typically carry a 1–5 year manufacturer warranty. Battery systems typically carry a 3–5 year warranty covering manufacturing defects. Specific warranty terms are listed on each product page. As an authorized reseller, all warranties are fully honored.

How to Size a Portable Power Station or Battery Bank
Choosing the right portable power station or battery bank starts with understanding two important specifications: capacity and output. Capacity, measured in watt-hours (Wh), determines how much energy the battery can store, while output, measured in watts (W), determines how much power it can supply at one time. Selecting the correct combination ensures your equipment can run your devices reliably without paying for more capacity than you actually need.
The first step is calculating your daily energy consumption. Make a list of every device you plan to power, note its wattage, and estimate how many hours per day it will be used. Multiply the wattage of each device by the number of hours it operates, then add everything together. This gives you your total daily energy requirement in watt-hours.
Once you know your daily energy usage, you can determine the battery capacity you need. Because all power systems experience some energy loss during conversion and operation, it's wise to include a safety margin. Dividing your daily energy requirement by 0.85 provides a practical estimate of the minimum battery capacity required for reliable performance.
Output power is equally important. A battery may have enough stored energy to run your devices for hours, but it must also be capable of delivering sufficient power at any given moment. The power station's continuous output rating should exceed the combined wattage of all devices operating simultaneously. Appliances with motors or compressors, such as refrigerators, pumps, and power tools, often require two to three times their rated power during startup, so additional surge capacity should be considered.
For example, a mini-fridge consuming approximately 60 watts around the clock uses about 1,440 watt-hours per day. Adding roughly 300 watt-hours for charging phones and laptops brings the total daily consumption to about 1,740 watt-hours. After accounting for system losses, a battery capacity of approximately 2,050 watt-hours would be recommended. In this situation, a power station in the 2,000Wh class, especially when paired with solar charging, would be an excellent choice.
As a general guideline, power stations between 300Wh and 600Wh are suitable for charging phones, laptops, lights, and other small electronics during camping trips or emergencies. Units around 1,000Wh are better suited for RV use, small refrigerators, fans, and short power outages. For home backup, off-grid applications, or powering multiple appliances, a system with 2,000Wh or more is often the best option.
If you plan to recharge using solar panels, daily solar production can be estimated by multiplying the panel wattage by the number of peak sun hours and then applying a real-world efficiency factor of about 70 percent. For instance, a 400W solar array receiving five hours of peak sunlight can generate approximately 1,400Wh of usable energy per day.
If you're unsure which size is right for your needs, provide a list of the devices you want to power and their daily usage. Our team can help you determine the most suitable power station or battery solution for your application.
